FORECAST IN DETAIL
The low humidity we were treated to over four of the last five days is outta here. Now the stickiness ramps up - peaking tomorrow into Monday. The associated deep tropical moisture will fuel any thunderstorms that form, impacting some areas with very heavy downpours - especially in the evening hours. We won't lose the humidity until Tuesday.
Today (Saturday): Considerable cloud cover prevents a true scorcher, but you'll notice the increase in humidity from the last couple of days. An isolated shower or thunderstorm could pop up in the afternoon (20-30% chance), but I think the best chance of storms waits until the evening. Highs reach the upper 80s to around 90. Confidence: Medium-High
3:30 p.m. UPDATE: A line of strong storms has formed southwest of Fauquier Co. which may impact the southern suburbs (including Fauquier, Prince William and then southern Fairfax County) between 4 and 6:00 p.m, possibly extending into the immediate metro area after that. These storms may produce damaging winds in excess of 60 mph. Watch these storms on our severe weather tracking station below...
Tonight: A disturbance rippling through the region or just to the north produces an elevated chance of showers and thunderstorms (50-60% chance) mostly between about 5 p.m. and midnight. It won't rain everywhere, but where it does the rain may be quite heavy and even produce some flash flooding. It will be a muggy night, with lows only falling to 70-75. Confidence: Medium-High
Keep reading for the forecast into early next week...
Tomorrow (Sunday): Humidity reaches into the gross category with dew points in the low 70s. When you combine this humidity with air temperatures heading up to around 90, it will feel more like the mid-90s. Thunderstorm activity remains a possibility - with odds in the 30-40% range...late in the afternoon and into the evening. Confidence: Medium-High
Tomorrow Night: Scattered showers and thunderstorms may persist through about 10 p.m. or so, then we're looking at just another muggy night. Lows fall to 70-75. Confidence: Medium-High
One more sticky & steamy day Monday with highs again approaching 90 coupled with unpleasant humidity levels. An approaching cold front gives us at least a 50/50 shot at thunderstorms during the usual late afternoon and evening hours. Overnight, storms end by mid-evening, followed by partial clearing. Thankfully lows fall below the 70s with upper 60s downtown with some low-to-mid 60s in the suburbs. Confidence: Medium-High
Drier, less humid air arrives from the north on Tuesday. So we should have plenty of sunshine and more pleasant highs in the mid-80s. We will need to watch where Monday's cold front ends up. It may stall close enough to the region to keep some clouds around and even some thunderstorm activity just to our south. Confidence: Medium
