First of the year---
Pretty powerful set up, especially this "early" in the year. Meteorological spring does begin tomorrow--
I expect a powerful line of storms to approach our far west regions by 2 PM and begin to move east. This could be impacting the area between 3 and 6 PM. The Watch is currently in effect until 4 PM-- looking at some data, I suspect this will be extended, especially areas to our immediate east and south, guessing until 7PM.
Keep your ears and eyes open to local media and the NWS for the latest updates.
