FORECAST IN DETAIL

After 2010's seventh heat wave, that lasted 6 days, and boosted our 90+ degree day count to 60 (the second most on record), this weekend's cooler weather is well-deserved. Even better, humidity takes a plunge, the sun shines brightly, and tropical troubles are behind us. We should embrace this stretch, as heat builds again by the middle of next week. Still no signs of appreciable rain.

Today (Saturday): Let's begin by talking about the humidity levels, which are not just going to be low but very low (afternoon dew points in the low 40s). The sun shines brightly in the dry air with some fair-weather cumulus clouds possibly dotting the sky in the afternoon. But cooling winds from the northwest at 10-20 mph make it a struggle to hit 80. Confidence: High

Tonight: With the very dry air mass overhead, temperatures tumble after the sun goes down. Lows plummet all the way down to as cold as the upper 40s in the cooler suburbs with even downtown areas dropping into the upper 50s. No air conditioning necessary, and an extra blanket may be in order in the cool spots. Crazy, huh? Confidence: High

Keep reading for the forecast into early next week...

Tomorrow (Sunday): Run Saturday through the copier and subtract the wind and scattered afternoon clouds, and you've got Sunday. High pressure overhead means sun-filled skies but this air mass is chilly. With many spots starting their day way down in the 50s, 80 is about as high as it gets by mid-afternoon. Confidence: High

Tomorrow Night: Clear, dry and cool overnight -- but perhaps a couple degrees warmer than Saturday night. Lows reach near 50 in the cooler suburbs to around 60 downtown. Confidence: High

A LOOK AHEAD

Whereas Saturday and Sunday have the early fall feel, Labor Day takes on more of the character of late summer. Highs climb back into the mid-80s but at least humidity remains fairly low. Monday night is pleasant enough, with lows in the 50s in the cooler suburbs to the low 60s downtown. Confidence: Medium-High

Another taste of heat returns Tuesday and Wednesday as winds flow out of the south. Highs head up to near 90. Humidity increases a bit, but is still pretty low. The overnight hours continue to be comfortable with lows from the upper 50s to upper 60s (downtown). Confidence: Medium-High

Why am I stuck at work? WHYYYYYYY?

Posted by: Brian-CapitalWeatherGang | September 4, 2010 12:14 PM | Report abuse

Brian, I feel your pain. I am at work all day and cannot get outside until this evening. To make matters worse, I am working at Huntley Meadows and there are hundreds of people coming and going and letting me know what a beautiful day it is here in the park! The silver lining is I am off the next two days. WooHoo!

Sweet (instead of sweat) day, but... why is the NWS calling for a steady temperature and high of 73 today when the temperature at middary reading at DCA is 80? Are temperatures supposed to be dropping this afternoon??

Next rain chance: Rather low, with cold frontal passage late Wednesday or Thursday. Sorry, much-needed-rain crowd.

Dry weather may be impacting cricket population...I haven't been hearing quite as much chirping or singing as last month during the more humid weather.

Crickets may be quiet but stinkbugs are active; have killed several indoors today. The fall invasion is definitely underway.

IF this nice day had been preceded by a week of similar weather we'd barely notice it. But when it was right after a week of 90+ weather, the contrast really makes it stand out.

Spectacular day!

Death to the stinkbugs! They're invading!
