- Moderate Risk Region Friday
Here is a look at the HRRR Model run this afternoon and evening. The first line which is already on Doppler is below, moving through the region by 1 or 2pm. After that, there may be some clearing before the next system this evening.
- 2pm HRRR Model Depiction
This is the depiction for this evening. At this point, we think there is a chance for heavy showers and storms, potentially severe, between 5pm and 9pm tonight. Something our team will be watching for is a Quasi-Linear Convective System with Line Echo Wave Patterns in them. Basically, those are just fancy words for a line of strong thunderstorms with some embedded areas of rotation.
The biggest threats today will be damaging wind gusts and flash flooding. There is a secondary risk for isolated tornadoes. Check out the Storm Prediction Center this afternoon for the latest on the highlighted risk area and to see if there are any watches for our area.
Live Super Doppler 7 is already picking up on some heavy rain southwest of D.C. Be sure to check on it throughout the day.

1:15pm UPDATE: From the Storm Prediction Center...Tornado Watch Likely… Thunderstorms will increase through the afternoon in a very moist and increasingly unstable air-mass. Isolated storms will first pose a threat for isolated severe weather in the form of hail and winds. Additional severe storms are likely as a forced squall line develops east of the Appalachians later this afternoon. Deep shear and tornado potential may increase across the entire region from late afternoon into the evening. One or more tornado watches will likely be issued over the next 1-2 hours. - Meteorologist Chris Naille
1:35pm Update: Tornado Watch Until 9PM For Frederick County, MD, Loudoun, Fauquier, Culpeper, Madison and all Counties north and west. A second watch box will likely be issued at some point over the next 1-2 hours which will likely include the rest of the viewing and listening areas.
