Winter Storm Warning has been issued..

I like the folks at the NWS over in Blacksburg. I'm not sure how we went from nothing, (under a inch or half inch, to a warning for 3-5 inches in these counties.. Patrick, Bedford, Franklin, Campbell, Appomattox and Charlotte.

Totals are 2-4 in the Blue and 3-5 in the warned area. 

The threat has always been there.. I mentioned yesterday how this COULD become a 3-6 or 4-8 inch event. With that, I'm not TOTALLY sold on a 3-5 warning event in those locals, but then again some places could end up with higher totals. So, bold call upgrading to a warning that fast, but the notice is short. And, there could be some issues still.  So, yeah.. they could verify but this doesn't mean it was the right way to do this.

Where are the models?

Most model data has a general 1-3 over most of the region. A few high res models have a 1-3 inches band west of LYH, a dryer slot near LYH and then 2-6 just east and south of town.

The GFS has been the lead model bring the snow in faster, colder and bringing the wrap around moisture in fastest. New Version Para totals:

Very broad area of 4-6 inches from 460 south to the NC border. 

My call:

Call me whiskers because maybe I'm a worrier. My gut says stay at 1-3, with up to 5 east of the Blue Ridge. With that, My official call:

2-4 inches region wide. Up to 6 possible in about the same places as the warned area. 

IF the Band that forms from the coastal slides west any more, 6-8 possible in the Danville/Lynchburg/ Appomattox corridor.  The 6z GFS is really close to this..

**not all the data supports 2-4, so this is a HIGH BUST potential. Looking at Radar, the snowiest models get the snow in here sooner and radar tends to support that. Schools may end calling it sooner too today, especially out west. Temps got a little cooler than modeled and cloud cover should be racing in**

Timeline: Snow may start in the Highlands and NRV by early mid afternoon and spread east by 5 to 7 PM. Heaviest snows out west will be before 2 am and Eastern areas between midnight and 7PM. Some rain will mix early on areas below 1500 feet and then along the NC Border till late evening. Snow ends 3-5 West regions, 5-10 east regions tomorrow morning. 

**if this busts- wave one slides to our north along 64. A few short term models show this. Wave two from the coastal doesn't make it that far west** 25% chance something like this happens and most places see under 2 inches. 

This is a day for frequent twitter and FB updates. Twitter: LynchburgWx, Facebook Keith David Huffman (would need to add me I think) and VirginiaWx FB page. Keep up the clicks on the ads if you like the efforts and forecasts. Share this for me!

If you wanted ONE more snow event.. read this blog!

At noon yesterday, we about bottomed out with the no snow camp. Outside the GFS, the other models were moving the one piece to our north with snow, the other south with rain and showing very little precipitation in our region.

We may have a true trend emerging. The NAM, which showed the north trend in the January event and the first to show heavier totals on the Valentines day event, doesn't want it to snow. The Canadian is also not for this storm, so these are in the no snow camp. However, the Euro model shows 2-3 inches and the MIDNIGHT run of the GFS looked better and now 6z run is even more intense.

Initial thoughts- I think a 1-3, 2-4 type event is on tap.It's not crazy to say this becomes a 3/6 4/8 type event based on trends today.  Flurries break out Thursday afternoon and then Late evening overnight, steadier accumulating snow develops until Friday AM. Thursday afternoon will have a rain/snow mix, some rain could mix in when the precipitation slows down AND it could end as drizzle. Martinsville to Danville we see a much rainer solution, but may end as a burst of snow that could get them in range of our target snowfall.

Greatest fear- Models trend to a more snowier solution, only to be a smidge too warm and then we get mostly rain. Especially east of the Blue Ridge (Lynchburg) Elevation will have a role in this event. 

WHY ARE YOU LEANING GFS/EURO- the trend has been for a stronger solution and the model trends are always more north.

6z GFS model run..

Total liquid falling- about .5 or .6 , expect much more to our south and east. You can see that this storm is blowing up RIGHT near our area.  Now, the bad assumption is to 

Snowfall totals from Wxbell

Surface temps will be near 40 when the snow/rain starts Thursday afternoon and evening. When the precipitation is heaviest, it will be right near freezing. 

Even if surface temps are OK, we are already on the borderline with temps aloft..


At 7pm Thursday, temps aloft are cold enough all the way down into NC, our battle is at the Surface

At 1 am Friday, Temps aloft have surged and mostly rain is falling just south of Lynchburg.

 at 7 am, you see cold air working back in from the west.  My assumption is that at 1AM, that warmth is still moving north, but likely slowed and then at 7 Am MOST places are turning back to snow. 

For you snow haters-- Look, if this comes to fruition, most will be melted by late Friday. 

There is a lot to be resolved still, but I think a general 1-3/2-4 event is on tap. We've got some wiggle room either way for this to be a bit more or next to nothing. 

As usual, will FB/Tweet out updated information as the event unfolds today. Keep up with the ad clicks! I do appreciate it! . 

Super Tuesday has no Super consensus.

The noon model runs yesterday looked promising in that we had a general idea of what the storm was going develop and general range of 2-6 inches. It wasn't perfect, but a general idea.

Then the Midnight model runs took place.

NAM and Canadian split the storm-- one piece to our north and one piece to our south.

Euro, which was the driest model at 1-2 inches in our area held serve, but it's parrallel model which takes over in ONE week looks like the NAM.

The GFS has decent liquid getting into our area but the storm is faster and most falls as rain.

There are off hour runs of GFS and NAM.

GFS is faster, wetter and snowless because of warmer temps (Not far off from the midnight run)

There is also a para GFS, which 2 runs yesterday showed 6-10 inches across all of our region.

2 options.

GFS- while warm doesn had the system bringing us precipitation. This is faster than the models and still could bring a 1-3 inch snow fall.

 NAM like solution where the northern energy is separate from the southern and snow falls to our north and rain falls to our south and we are basically dry...(Maps VIA Wxbell)

If the models had held server last night, I would have felt pretty good that we see a 2-4 inch event around here. The fact that even the Euro, which verifies best at 500 MB is split between it's current version and upgrade is even more confounding.

The official Virginiawx.com position is:

I'm going to punt until the next model cycle. Obviously, when a decent storm is on the way at 72 hours out we usually have a pretty good handle on it, so this doesn't bode well. Having said that, I think we could still squeeze 2-3 inches out of it if everything goes well.

Possible Snow event Thursday Night and Friday.

A lot can go wrong still, and we are 5 days out.

First, another storm will impact our region earlier in the week and bring a round of showers. I don't anticipate severe storms with this event. 

A pretty strong cold front will push into our region with some very cold air for the time of year. A storm will form and impact our region. 

Model break down: 

GFS- Yesterday the model was very fast bringing in the cold air and pushed the low WELL south, it was a MONSTER storm over North Carolina with the heavy snow band reaching the VA/NC border and the 4 inch line reaching 460. Model runs since then lost the storm. 

Canadian: Pretty much has nothing. 

Euro: Has some consistency bring a low due east. There isn't much wiggle room at all as we are on the southern fringe of accumulating snows. I'm not able to post the "paid" snow map I get but the 4-6 inch line basically runs along 460 and basically at the VA/NC line there isn't much snow at all. 

7 PM Thursday- Low pressure is near Nashville. You can see a High Pressure building in as well noted over MN/WI area. On the precipitation maps, snow has broken up north of our region along the Mason Dixon line. 

24 hours later our low is a couple hundred miles off shore and has strengthened nicely. 

Many details to work out. The euro "spits out" 5 inches of snow in LYH and ROA but as the storm approaches, at 1 AM we are actually warm enough for mix or even just rain east of the Blue Ridge, but then as the low wraps up we kick over to a fast heavy period of heavy snow.  (* I can't post the pay euro maps, but these are the free ones in 24 hour increments that don't show precipitation or snow. 

From Charlottesville to Northern Delaware, as the storm blows up the heavy snow that blows up near us really impacts them an dumps 8-14 inches. 

If you don't want snow-- Speed the storm up and don't let he cold air get in place. THis would result in a more north storm track.

If you want MORE snow- slow the storm up, get the cold air in faster. Rather than a Nashville to Boone to Greensboro track, get a Chattanooga to Charlotte track. That extra 75 miles will make all the difference. 

The storm BOOKS out of here Friday Morning and Friday afternoon temps are back into the 40's via the European model.. March snows, in fast and out fast. 

My thoughts: There are some reasons why we could see a more suppressed track with cold air moving in. However, many reasons why we could see this thing trend 100 miles north and we just get a few rain showers too. No call yet, but my inclination is to expect a more northern track at this point. 

Severe Weather Threat...

First, my Grand Finale is looking more and more like Delaware City or even worse, but I still have hope for the period Match 5-15. Obviously, The clock is running and every day the sunlight is a little longer and brighter and my time is close to running out. Snow Haters, don't spike the ball just yet.

Tomorrow: Our storm we tracked last week for Wednesday is now going well west and presents a severe weather threat. Now, there are factors that could limit this, especially areas along and west of the Blue Ridge. With that, I wanted to make you all aware of this.

Looking at SIM radar, it seems two waves of showers and storms come through, the second being the greatest threat to have tornadic activity.

This is Radar right around 5 with the second round moving through. 

You can see our storm starts near SML and strengthens as it moves rapidly NE from there. 

4pm MAP of greatest risk for Tornado..

One hour later  the risk has shifted east. 

I'm honestly skeptical places just north of Martinsville to just south of Lynchburg see severe storms. There will be a cold air wedge in places and the models QUICKLY move out the wedge and then stir up some storms. 

Not our area temps in the 40's with much warmer air to our east.  at 1PM

3 hours later, we've spiked to near 60 and Tornadic cells are are supposed to form. Now, I'd never rule out anything from happening but I can't remember a time where in our area that we've had a wedge break and tornadic cells pop up that quickly. I would contend that based on climatology alone, the highest risk is east of a line from Danville to Pamplin. With that, please be aware of all the weather reports and be cognizant of all watches and warnings issued tomorrow. If the sun pops out late morning early afternoon, it could mean game on. I'll tweet out and FB update information as it comes available. 

How do you find Will Smith in the snow?

You look for the Fresh Prints..

Today should be a VERY nice day, temps up near 60. 

Tomorrow will be warm as well, but there is a shot for some showers in the afternoon, which could ruin outside time. 

Next weeks event: Trending more like NOT much of anything but rain. Anytime there is some dry air, a 20 minute sleet shower is possible and sometimes if it starts right around dawn, a little freezing rain takes place. With that, the bulk will be rain and it could be a big rain. Much of next week Sunday till Thursday could have some rain each day. 

How's the Grand Finale Looking?? I still like my prediction of one significant and one minor event before spring kicks in. On January 6, I stated no changes to my overall ideas for the winter, conceding that December was much warmer than I thought. 15 days later, we were on the Eve of our big event. 

If I had to pick a date, March 7th, give or take 4 days for those events to happen. (Let's say the week From March 4th to March 11th look best.

PNA: Measures ridging on the west coast.. looks positive, that's good

AO: Measures blocking over the north pole ...looks negative, that's good

NAO: Blocking in the Atlantic to lock in cold air ... looks negative, looks good. 

EPO: Ridge/Block over Alaska, BONUS cold air. .. looks negative, indicating blocking over Alaska. All good signs. 

If the patterns does not develop as I expect, we could be looking at a "Delaware City Finale"

Shortly after this, the pattern will break down March 15th ish... and Spring emerges. 

We're heading to the GRAND FINALE!

 Winter has one last stand and like a good firework display, the GRAND FINALE could be incredible for you snow lovers and miserable for you heat misers.

Growing up, I can remember 3 types of Grand Finales:

1. The standard. My great grandmother owned a house at Slaughters Beach, a location about 20 miles north of Rehoboth Beach, Delaware. The Fire Company hosted the fireworks each year and once the siren went off, the show started and it was a normal  fun grand finale to end the show. 

2. The Phillies game. My family went up to a Phillies game when I was 10 or so to see the 4th of July display. I figured the show would be pretty incredible and from the second the "Power 99" (local radio station sponsor) started shooting out sparks, my jaw dropped in amazement until the show was over. The Grand Finale is still the benchmark by which I grade all firework shows. 

3. Delaware City. One year we stopped someplace new because we were not going to my grandmothers. Some of the shells didn't launch high enough and pieces of burning paper fell in the crowd. During the grand finale, the first firework didn't blast high enough and each subsequent firework got caught in the wake and blew up. There was a ton of noise, but no fancy light show at all. I look back and laugh because it was that bad and such a let down. 

Winter has until about March 10th or so based on the pattern. I see three ways to have OUR Grand Finale of this Winter. 

1. We get ONE more storm above 6 inches and one storm below 4 inches. We'd be above normal snowfall for the winter but within the range I predicted based on the Strong Basin wide, but more western based El Nino. 

2. We Get a Phillies game with 2 or more events over 6 inches and a couple of other minor events. This will put us on the EDGE of a top 10 winter in our area snowfall wise. 

3. We get Delaware City-- Had a lot of potential but something goes wrong and we are done for the year snowfall wise. My winter outlook falls short, snow loves give me a sympathy pat on the back while you snow haters cackle into what could be a SUPER LA NINA next winter, which are often warm with reduced snow. 

Good news for those of you who don't like snow-- I think when the pattern change mid March, The End of the month is actually pretty nice/warm In like a Lion, Out like a Lamb. 

I'm going to hedge on a good Ole Slaughters Beach Grand Finale. You'll be impressed, but you'll know there were better events and better years. 

Next Weeks Event:

The weekend will be great with 60-65 degrees Saturday and Sunday. Some cooler air filters in Monday and while some COLD air moves in from the west a storm approaches from the SouthWest on Tuesday. 

My take is the best potential now makes this the "under 4" inch event as cold air is LATE getting here and we pull something out late, but the bulk of a strong and wet storm is liquid, not frozen. West Virginia into PA does very well away from the coast. 

What is needed: It is presenting as a two wave system. Wave one is all rain, wave two is rain ending as snow, some model data has 10 inches Roanoke/NV and 4-6 LYH. If we can get the cold air in faster and slow the storm up, we could make this a bigger event. 

On this map below, note how there is a storm over New Foundland, This will bring in cold air and you can see a high pressure centered over  MN and that SHOULD be pushing cold air in our region. This is Tuesday Night at 7PM.

This is Wednesday Night at 7PM-- Cold high anchored over Southeast Canada  and broad low over SC/GA. The map is actually very warm at the surface, but SHOULD be colder.

Note that 12 hours later, our low is NE of VAB. If we get This time frame, we could see a 4+ snowfall. Anything sooner, I fear the models would SHOW a few inches but we'd end up disappointed. 

So, with this being round one of our "Winter Grand Finale" I will watch this event closely. This will be a BIG storm for some areas.. Foot plus. I think we catch a little something, but the severe totals will be 100 miles or more north and west of us. IF that cold air finds it's way in sooner OR if the storm is 12 hours slower, we could be looking at January 22  all over again. 

If this falls apart, we should have 2-3 more shots at some snow and ice after this. 

Keep up the clicks! You all rock.
