FORECAST IN DETAIL

Our interruption to regularly- scheduled D.C. summer weather is welcome programming for just about everyone. Still warm enough to enjoy the pools but no sweat to those out and about. All  good things must come to an end but it looks like a  fairly slow demise with humidity only increasing steadily on Sunday, when a tropical  surge brings us our next chance of rain.

I  am beginning to  wonder  if  I will ever need to  break out the sprinkler this year. The gardens and parks are looking great, so consider a trip  to one of the many great ones in this area. Just  watch out for the overworked mowing crews!

nice day
Today (Thursday): The morning is cloudless or close to it and the afternoon sees just a smattering of pop up clouds as humidity levels remain uncommonly low for these parts. Breezes are light from the northwest. Highs only top out in the lower 80s for most. Confidence: High

Tonight: Evening cools quickly into the 70s and the stars should be bright in the clear, dry air. Winds calm and lows reach the mid-50s in the suburbs and the low-to-mid 60s downtown. Confidence: High

nice day
Tomorrow (Friday): Sunshine remains dominant. Even afternoon pop-up clouds are probably in short supply. Humidity levels remain unseasonably low. Barely a breath of breeze is not much of a problem as highs hold in the low-to-mid 80s.  Confidence: High

Tomorrow night: Sidewalk cafes will be in high demand in the evening with temperatures in the 70s and calm conditions. Lows fall to the low-to-mid 60s. Confidence: High

A LOOK AHEAD

Saturday is only slightly warmer and more humid and a far cry from more typical Washington summer conditions. Clouds become more  numerous as a disturbance in the lower Mississippi Valley starts to feed moisture our direction.  Shower chances are only 20% late in  the day and outdoor activities should be fine with  highs mainly in  the mid-80s. Clouds continue to increase overnight with lows in the mid-upper 60s. Confidence: Medium-High

Sunday sees little of its namesake as clouds block the sunshine effectively and shower chances start to increase. Despite increased humidity it is tolerable as highs are likely to do  no more than low-to-mid 80s. Rains chances during the day are 30% but increase to 50% overnight. Lows reach the mid-to-upper 60s. Confidence: Medium

Monday is still likely to find us in a moisture feed from the south. Given our season of monsoon, there should be at least a 50% chance of getting showers in any part of the region. Cloud shackled highs should hold in the low-to-mid 80s. Humidity is more seasonable, in other words, sticky. Confidence: Low-Medium
