Forecast: Stormy End To Our Weekend

By Brian Jackson

*Severe Thunderstorm Watch in effect until 8 p.m. for metro area.*

By Brian Jackson

The approach of a cold front heightens thunderstorm chances this afternoon and evening. Some storms may be severe so stay tuned. Before storms begin to affect our area from the northwest, we should see a fair amount of sun and warming today. But calling today's storm-producer a cold front seems a bit controversial as temperatures may actually warm after it passes by.

TODAY (SUNDAY)

Radar: Latest mid-Atlantic radar loop from the National Weather Service. Click on image to expand, or here to zoom. Refresh page to update. What's UTC?

P.M. thunderstorms, 85-89. The front approaching the metro area late today will likely set off some thunderstorms over the region. A few of these storms could be strong/severe packing gusty winds. A good deal of sunshine should allow temperatures to reach the upper 80s to near 90 before the clouds build and storms develop. Winds will be out of the west at 5-10 mph but potentially much higher in any area of storms.

Storms will continue into the evening hours but will decrease with the loss of heating. Most storm activity should diminish before midnight with skies staying mostly cloudy through the early morning. It won't be unbearably sticky but still quite mild overnight with lows around 70.

Confidence: Medium-High

TOMORROW (MONDAY)

Sunny, not as humid, 87-92. Though we'll be behind the cold front, temperatures won't cool with strong sun and little in the way of cloud cover. While temperatures stay hot, you will notice lower humidity and a nice breeze from the north at about 5-10 mph.

Monday night will be relatively comfortable for us. Clear skies and dry air will allow for cooling with lows in the low-to-mid 60s in the suburbs to the upper 60s to near 70 downtown.

A LOOK AHEAD

A hot summer pattern returns midweek with chances for afternoon/evening showers and storms throughout the forecast period.

On Tuesday, the front may pass back overhead as a warm front from the south and give us a chance (30%) for afternoon thundershowers. Even if it doesn't make it all the way back it will still be close enough to ignite some scattered activity over our region -- especially south. Otherwise, we'll see a good bit of sunshine and highs in the low 90s. Confidence: Medium

On Wednesday, it's a similar story as we warm to the mid 90s with a chance of afternoon thundershowers. Confidence: Medium-High
