Isaac on the docket...

Isaac formed and is now not far from impacting the Leeward Islands by this time tomorrow. It should hit Hurricane status just past this point.


From here, the speculation is does it stay far enough south and NOT get beat up badly by Hispaniola. There are mountain peaks OVER 10k ft on that island and it would not be the first time a 'Cane never reached it's potential due to land interaction. Guidance has shown some variety-and the NHC has marked this as the most likely track.

It will eventually take a NW jog-- and it depends how quickly.

My guess so far is it takes the south side of the "cone" over the next 24 hours and we will adjust from there. US interest from FL SW into the Gulf should monitor at this point.

Here's a quick loop from the GFDL-- crosses the storm over Hispaniola, emerges into the Bahamas and hits in the vicinity of Miami.

Cooler and a little rainy pattern on the way..

Cool, rainy Sunday this week with SOME heavier spots were 1-2 inches fell especially to the west of Lynchburg. There was a sinkhole on 81 in between Lexington and Staunton today. I checked the some of the rainfall totals and didn't see anything too extreme so my first guess is this could have just been a long standing issue. However, not having data from this exact spot makes this a big guess.

This pattern will persist for the first few days this week and we will have some chances of showers and thunderstorms through the early part of the week. 

The tropics may be heating up. We do have Gordon taking the rare form and move west to east and should be very close to Portugal in a couple days but likely down to just a tropical depression. After that, a system about 1000 miles west of the Cape Verde Islands looks prime to develop into something very soon. This has  a decent chance of being a "news maker".

Friday Storms.

This spring/summer has been above active storm wise for something you would remember--

HUGE hail event in late March that was up to 6 inches deep in places, Derecho event on June 29th that knocked out power to 90% or more of the region.

Friday MAY add to that event. At this point-- the SPC has placed our area under a 30% risk for 25 miles of any specific point. Considering we are 72-90 hours away-- that's a pretty bold call. We've got a stronger cold front moving in, and the deciding factor may end up being how much sun we get Friday. If we keep the cloud cover from the storms Thursday (not likely to be WIDE severe that day) Despite good parameters, we could avoid another significant event.

Tropical Wise, Florence formed and dissipated without much fanfare, as we expected. Ernesto has been all over the place forecast wise, but seems like it will make landfall in the Belize/ Mexico Yucatan region. top winds are around 80 MPH currently and could MAYBE touch 90 before landfall. I've got a friend who is a dedicated chaser and I'll share some of his updated when it gets rolling down there. His website is

Rainy pattern update--

This should be a cooler and somewhat wetter weak upcoming. I do think the best rain totals and rain coverage is south of our region, but a region wide .5 to 2 inch rain event is likely.

Latest QPF from the HPC shows minor changes--Best chance for rain will be Monday and then more showery and thunderstorm stuff Tuesday into Wednesday.



Earnesto is in trouble-- has not strengthened as much as thought AND is too far south. Landfall maybe Hondorus and or Belieze. Latest NHC plot--

Florence formed as we thought--as it progresses east, likely to NOT become a Hurricane and may just weaken as it goes well north of the Caribbean Islands. I don't see this as much of a threat to anyone. 

Maybe some rain?

Drought has been a "buzz word" in the news recently-- and some parts of the nation are in dire straights. Here in the Commonwealth of VA, it's dry- but not HORRIBLE dry. Parts of the Southeast, and much of the mid west are in HORRIFIC shape the rain wise.

With our "minor" drought conditions here (there was impact from the heat on local crops-- not specific to drought) we will get a nice break of cooler and wetter weather. We've had a ton of showers and thunderstorms but nothing "region" wide. I can think of 2-3 times this summer where the models showed a decent rain and we got NOTHING or very little. I do like how this looks at this point. As a reference, here is the HPC's rainfall total over the next 5 days.

These events tend to be more showery and the gradient won't look anything like that. However, I like how this looks and think we do see a region wide .75 to 2 inch rainfall over the next 5 days. A little more could be in the pipeline AFTER that. 

For those who enjoy tropical events-- Earnesto is fighting it's way through some tougher conditions and should achieve hurricane status later this weekend/early next week. The question is does it run into the Yucatan and just fade out or graze it, end up in the gulf as a more strong threat to the Gulf states region. My take now is I'm hedging more towards the graze into the gulf, but we've got plenty of time.  If you're a map person, the NHC has some good easy to read info on their website.

There was a nice flare up of convection near the Bahamas recently and that has slight potential to form but what I'm really interested is the flair up off the Africa coast-- labeled as LIKELY to become Tropical System in the next 48 hours. We should have Florence by early next week.

Stopping by the blog on a summers evening..

Well Howdy,

I must be the WORST weather blogger with the excessive heat and a few incredible thunderstorms that I've done NO updating on. NONE--

My goal is to improve that. I'm hoping to reformat the entire blog into a REAL website, have daily updates and a bit more features. Time frame on this launch is Oct (tentative)

Today's storm looked a little exciting for a minute, but once it approached there wasn't much where I was on Timberlake Road near Lynchburg. Other places had some hail--etc but none where I was.

So, my goal is to get more consistent updates and move away from the blog format. Winter weather is my greatest passion, but I do get pumped up over Severe and Hurricanes. I'll start to add more information on that as well to provide a more comprehensive service. With that, I'd suggest everyone follow Sean Sublette from WSET and Jamie Singleton when a severe event is on tap. For my money, they are two best local FB/Twitter guys. WxRisk.com is worth following on FB-- he does more medium and long range stuff and is "full of personality" as well.

However, a little pre thought about winter. It seems clear that we are heading into an El Nino. If you recall my winter outlook in Winter 09/10 about how a moderate,west based El Nino is best for our region. Breaking that down a little, anything above a +1.2 in regions 3/4 of the Pacific is GREAT for us. The model data is not exact but some guess have it CLOSE to 1.2 but not quite there. (East based El Nino's are another beast as well)  Anyways, if you want a decent winter-- just on stats alone that 1.2 places us in the best statistical place for an exciting winter.
