While we won’t see much sun today, the milder temperatures are a reasonable trade-off. Tomorrow wins the best of the litter for the next 5 days with dawn to dusk sun and none of that pesky high humidity to mar it. The weekend is no bust but thunderstorm chances return Sunday as does the heat and humidity.  Still no grousing from me as my garden thrives and another cool push early next week keeps the grip of summer a very  tenuous one this season.

Want more good news? As of yesterday, the normal high is down a degree from its peak of 89 at Reagan National. The bad news is that it takes another two weeks to drop another degree while on the daylight front we are losing nearly 2 minutes a  day!

Today (Thursday): The most likely time for showers or a thunderstorm should be very early in the day and right around midday. By afternoon most of the big storms are more likely to form far to our south, say Richmond, and keep moving south. There is still a reasonable chance of you getting wet (40 percent in our northern suburbs to 60 percent in our southern suburbs), so no stepping out without the  umbrella. Humidity holds tough but the abundance of clouds helps to hold highs in the low-to-mid 80s. Breezes shift to come from the north early at a brisk 10-15 mph pace. Confidence: Medium-High

Tonight: Most showers should be long gone by evening but a stray on the south side of town is still possible (< 20% chance). For most,  the evening is worth getting out for with readings in the 70s and lower humidity carried in on light north breezes. Skies clear during the evening and lows slip to the low-to-mid 60s. Confidence: Medium-High

Tomorrow (Friday): Unfettered sunshine is just fine today as low humidity (dew points in mid-50s) keeps it comfortable. Add in just a hint of a breeze most of the day and a good seat at  an outdoor cafe might be hard to come by. Highs top out in the mid-to-upper 80s.  Confidence: High

Tomorrow night: The heat of the day quickly drops off at sunset thanks to that low humidity. Look for a sliver of moon in the western sky at dusk followed by a sky full of stars throughout the night. Lows hold in the mid-to-upper 60s. Confidence: High

A LOOK AHEAD

Saturday starts feeling a whole lot more like typical  summer as southerly breezes gradually pick up and so does humidity although at a gradual  pace. There is plenty  of sun and this  allows most areas to reach or just break  the 90 degree mark.  Clouds increase overnight and a stray  shower or thunderstorm could slip into  the region just before dawn (20% chance). Lows only drop to the low-to-mid 70s. Confidence: High

Sunday is back in the soup tureen with high humidity (dewpoint in lower 70s). Despite plenty of clouds and an ever-present thunderstorm potential, highs still manage to reach the uncomfortable lower 90s.  There is a 70% chance of getting wet at some point with  the most likely drenching to take place in the evening. The potential for severe activity is low but bears watching. Overnight lows again get stuck in the low-to-mid 70s. Confidence: Medium

Things are still unsettled on Monday with showers and a stray thunderstorm possible (60%) through much of the day. Highs only  make the  mid-to-upper 80s which is a consolation, but the grand prize  comes the following few days when drier, cooler air settles in.  Confidence: Medium
