Forecast: Cold Front Coming With Showers, Storms
Some thunderstorms today could be strong or severe
A significant cold front is on the way into the area today and it will bring the potential for some strong to possible severe thunderstorms, from late this morning into the evening. Once the cold front sweeps through, the stage will be set for some pleasant September weather on Wednesday and Thursday. Warmer weather, increased humidity, and more thunderstorms get re-introduced to the DC area by Friday and the upcoming weekend. It looks like our dry August is definitely behind us!
Showers and thunderstorms today. Highs in the upper 80s. We should expect one of those variable cloud cover days with scattered showers and thunderstorms, especially after noon. The Storm Prediction Center is predicting an opportunity for severe thunderstorms today too, so expect a chance for some heavy downpours and gusty winds. Chance of rain is 70%. Highs should be in the upper 80s throughout the area, but expect typical cloud and shower-induced temperature volatility today.
Tonight, storms could linger into the evening hours, but the winds should shift and temperatures should begin cooling. Look for lows in the lower to middle 60s with cooler breezes developing.
Keep reading for the forecast through the weekend.
Sunshine returns. Top notch hump day! Highs in the lower 70s. The cold front should do its good work by tomorrow and the day should be quite comfortable with highs only in the lower 70s and nice breezes from the northwest. A few scattered clouds are possible.
Wednesday night is shaping up to be quite cool with lows in the 50s throughout the area (even downtown!). This potentially coolest night of September so far should also come with mostly clear skies.
Thursday stays with the "nice weather" theme by offering up only lower to middle 70s for highs. Look for mostly sunny skies and pleasant breezes again. Lows Thursday night in the 50s to lower 60s. Confidence: Medium-High
Friday sets another change in motion with an increase in temperatures and a little humidity. High temperatures are forecast to reach back up to near 80 through the area and we must re-introduce a chance of showers and thunderstorms (30%). The modest September humidity should keep lows back up in the upper 60s Friday night. Confidence: Low-Medium
The weekend keeps to Friday's theme of more warmth, clouds, and scattered shower and thunderstorm chances (about 30% each day) due to the proximity of a frontal system. Look for highs to hold up in the lower to middle 80s with lows primarily in the 60s. Hopefully, as the weekend gets closer, we should get a better handle on which day of the weekend has the better chance of being the nicer one. But it does appear like our drier pattern of our pre-Hanna days has come to a close. Confidence: Low-Medium
