Severe Weather and Snow Update Friday

Unfortunately, the models have been trending to us getting dry slotted on Friday, giving us no or limited flakes falling on Friday. A bare ground is expected for many, with up to a trace of snow, but even that isn't likely. However, the chances for severe weather tonight has increased.

There is now a marginal risk for a lot of our region(including all of MoCo), and a chance for some non-severe thunderstorms elsewhere(in the DMV). Our western and southern areas are in the marginal zone, while our northeastern areas are in the non-severe thunderstorms area. 


The main concern here is hail. In the brown area, there is a 5% of seeing 1 inch or larger in diameter hail in any given location 25 miles away from a certain point. This isn't the chance of any given location seeing any size of hail in any given location in the brown area, and that is likely much higher than 5%. There might be some isolated supercells in our western and southern areas, but they aren't expected to form into tornadoes. Damaging winds and some isolated tornadoes cant be ruled out though, and you should be preparing for them. Some thunder and lightning are actually kind of likely this time, mainly in our southwestern areas. As severe weather starts to become more common in our area, I will be making more posts about them. Until then, stay safe!
