FORECAST IN DETAIL

Temperature Map

Temperatures: Latest D.C. area temperature map. See interactive map on our Weather Wall.

The next couple of days are pretty normal by D.C.’s summer standards: highs near 90 with a small chance of late day storms.  This week’s hottest, most humid and stormiest weather probably hits Wednesday and Thursday, but this is also the same time a cold front slowly edges through the region.  So by Friday – July 4, we may see some relief from the mugginess.  A tropical weather system  off the coast of the Carolinas later this week may be a nuisance or even hazard at the Atlantic beaches, but probably avoids areas west of the Chesapeake Bay.

Today (Monday): It’s not as nice as the weekend, but not horrible.  Under partly sunny skies, highs climb into the upper 80s to near 90, with humidity in the moderate-high range (dew points in the mid-to-upper 60s).  The chance of a late day storm is just around 10-20 percent (highest chances towards the mountains.)  Light winds from the south around 5-10 mph. Confidence: Medium-High

Tonight: Any storms diminish quickly with the loss of daylight.  It’s warm overnight, with lows from the mid-60s in our cooler suburbs to the low 70s downtown. Confidence: Medium-High

Tomorrow (Tuesday): Humidity grows slightly higher (with dew points around 70) and the temperature ticks up as well.  Highs climb to near 90 or even into the low 90s, and it feels like 95-100 factoring in the humidity.  The breeze from the south at 10 mph does just a little to take an edge off the heat. A few isolated storms could pop up in the afternoon, but chances of getting hit are just about 20-25 percent (highest odds west of the District). Confidence: Medium-High

Tomorrow night: An evening storm is possible (but not probable).  Otherwise, partly cloudy skies and muggy, with lows 69-77 (suburbs-city).. Confidence: Medium-High

A LOOK AHEAD

Wednesday and Thursday are both very warm and humid with a pretty good shot at showers and storms, especially during the afternoon and evening hours. A few of these could be on the strong side, so keep apprised of forecasts as the week goes on.  Highs both days range from 90-95 (probably closer to 95 Wednesday), with overnight lows in the upper 60s and 70s. Confidence: Medium-High

The slow-moving front responsible for our storm chances from Wednesday and Thursday shifts to our south and southeast, which should allow for some cooler, drier northerly winds to stream in around July 4 through the weekend.  During the day Friday (Independence Day), clouds should slowly decrease (unless the front slows down, which would then introduce rain chances), allowing for partly sunny skies in the afternoon, with highs 80-85.  The prospects for Friday night fireworks displays are promising with dry weather favored and lows mostly in the 60s.  Both weekend days are looking good right now, with partly to mostly sunny skies  and highs in the 80s (lows in the 60s Saturday night). Confidence: Medium
