FORECAST IN DETAIL


Clouds: Latest mid-Atlantic infrared satellite shows movement of clouds over past two hours. Refresh page to update. See more maps on our Weather Wall.

The conveyor belt for showers moves just far enough north today and tomorrow to dry things but also lets in a little hint of summer, or weather more typical of mid-June. An extended sweat-fest does not seem likely as clouds and a few showers come to our rescue on Saturday but make outdoor activities hit-or-miss.

On the bright side, those of you “bawlin” from the pollen should see enough rain Friday night into Saturday to get relief. For those with a west view, Mercury starts appearing above the horizon beginning Sunday through much of the month at dusk in a rare display.

Today (Thursday): The clouds are likely to linger at least into mid-morning with a slight chance of shower (<20%) before  the responsible warm front creeps north. Clearing by midday allows temps to jump to the low-to-mid 80s. Breezes are light from the west but enough to keep the heat under control. Humidity levels are moderate. Confidence: Medium-High

Tonight: Evening is perfection with starry skies, calm winds and readings in the 70s. Lows only slip to the upper 50s to lower 60s. Confidence: High

Tomorrow (Friday): An unobstructed sunrise quickly gives way to a barrage of clouds steadily advancing from the west. The result is a mostly cloudy afternoon but just a 20% chance of a shower, mainly late afternoon. Breezes are light from the south. Despite the nature provided sun screen, highs should still reach the low-to-mid 80s thanks to a warm start to the day. Humidity levels climb as well, making AC start to seem like a good idea. Confidence: Medium-High

Tomorrow night: Clouds are persistent but showers are very spotty with only a 40% chance that your location gets wet. Temperatures are very slow to drop, at least in areas without a shower and most of the region only bottoms out in the low-to-mid 60s. Confidence: Medium-High

A LOOK AHEAD

Saturday is a keep the umbrella handy day but showers are still likely to be scattered and brief. Your chance of getting some of these showers is up to about 70% but don’t look for any more than a quarter inch in most spots. The cold front kicking off these showers is a dying one, keeping dynamics pretty weak. Highs should be held to the upper 70s wet spots and lower 80s drier ones. Showers taper off after dark and lows reach the upper 50s to lower 60s. Confidence: Medium

Sunday should see a steady decrease in clouds and that will up the warming factor, with highs back in the low-to-mid 80s. The clear evening should allow the first good look at Mercury about 10 degrees above the horizon around 9 p.m. with temps comfortably in the 70s. Lows only fall to the low-to-mid 60s. Confidence: Medium-High

Monday has the best chance to see highs escalate up to the mid-to-upper 80s, that is if clouds and showers stay to our west as expected. Humidity should be moderate but since we are still acclimating, so it could be a bit uncomfortable. Confidence: Medium
