Severe Thunderstorm Watch

Anticipating the storms through this evening, the National Weather Service has issued a severe thunderstorm watch for the entire region through 10 p.m.. “ ...

Even with shallower convective clouds (lacking significant lightning and thunder), we are concerned that downdrafts within the clouds may bring down blasts of strong wind in locally damaging gusts. With the influx of southern moisture and rising air, waves of showers will develop and transit our region through the afternoon and evening. Our concern shifts to the early evening, as the front nears and a pocket of unstable air develops just along it. A look at the day’s forecast map reveals that a warm front pushed through our region last night, ushering in wind from the south and a milder and humid air mass. While the instability may be somewhat lacking through a deep layer, the low-level wind fields are exceptionally strong and ideally configured such that any deeper cells may achieve rotation. If a severe thunderstorm (or tornado) warning is issued, it means a storm is imminent for your location and you should seek shelter immediately. The larger Severe Thunderstorm Warning covering DC, around the Beltway in Montgomery and Prince George’s counties, and west into central Fairfax County is in effect until 9pm. This is Level 2 out of 5 on the severity threat scale. A possible tornado was located over Chantilly of Centreville at 8:21 p.m. and moving east.

Still watching heavy rain, lightning and gusty winds moving through northern D.C., the north side of the Beltway, and along I-95 between D.C. and Baltimore. All this activity is moving east.
