Today: Sunny and pleasant. 80-85 | Tonight: Mostly clear and cool. 60-65. | Tomorrow: Mostly sunny and hot. 87-91. | A Look Ahead | Get Express Forecast by E-mail


Just when you think the summer is over and the 90s are finally vanquished for this year, here they come again, trying to best that 1980 record. After an excellent day today, the heat is back in action tomorrow through possibly Saturday. Look for humidity increases sufficient to justify air conditioning. Will this week be the end of 90-degree weather? It is tough to say. This pattern type suggests Mother Nature may have at least one more round of heat in her yet.

Today (Tuesday): There is little to complain about today, except for us allergy sufferers. Brilliant sunshine and still-comfortable low 80s temperatures dominate the Washington, D.C.-area weather scene. Light winds blow from the south direction, especially by afternoon. Confidence: High

Tonight: Mostly clear skies with warmer overnight temperatures that only drop into the low-to-mid 60s. Light winds from the south again. Confidence: High

Keep reading for the forecast through the weekend...

Tomorrow (Wednesday): Mostly sunny skies is the good news, but a high temperature reaching up to around 90 is probably the bad news. Dew points increase, so you'll probably notice the increased humidity by the afternoon. Some clouds may arrive in the area by late afternoon into early evening. Confidence: Medium-High

Tomorrow Night: Partly cloudy skies with a 30% chance of showers or thunderstorms. Low temperatures range from the upper 60s to low 70s (yes, muggy). Confidence: Medium


Thursday brings more dominant sunshine, but hotter temperatures are expected to menace our area. Low 90s seem to be the most likely outcome again despite the fact that this is the first full day of autumn! Thursday night temperatures are again in the upper 60s to low 70s under mostly clear skies. Confidence: Medium

Friday is another hot one with mostly sunny skies, highs in the low to maybe (gulp) middle 90s and moderate humidity levels. Friday night favors warm and humid conditions with those upper 60s to low 70s again. Confidence: Low-Medium

The weekend is setting up to be a divided one. Saturday may find lingering heat with highs in the 80s to maybe 90 again under partly cloudy skies. A slight chance of an afternoon shower or thunderstorm is expected. Saturday night should be partly cloudy and turning cooler with lows in the 60s. A more comfortable Sunday may salvage the weekend, but we worry that cloudy or partly cloudy skies linger with a chance of showers, especially early. At least our high temperatures return to a more comfortable 70s-level. Confidence: Low

When it hits 91 on December 4, will we saying "I hope this is the last of the 90-degree days". Oy vey, enough heat already (and it doesn't even start up again until tomorrow...).

Where are we in terms of the record now? I mean hell, if it's gotta be hot might as well go for it haha.

I like my weather like I like my people- passionate and sure of their beliefs! If it's going to be hot in the summer, let it be hot! No one likes waffling, moderate, un-opinionated people-and why should we like such weather!?

I believe we are 4 90+ days away from tying the 1980 record number. I am thinking we could net our 3-4 days here between Wed and Sat. The latest we've seen 90s around here is about Oct 11th or so, so we'll have time for a few more heat events believe it or not!

I am loving this forecast! I froze walking my son to school this morning so please... more warmth!

Already looking forward to next spring/summer!

Has mother nature been diagnosed as bipolar yet? Chick is crazy.

rumbly45 - by chance do you know how cold the temperature was during your walk? I am always on the lookout for locales hitting the 40s for the first time this season.

authorofpoetry - I understand where you are coming from. 2010 has been quite challenging with its highly variable weather, eh?

Didn't punch below 50 this morning in the Blue Ridge at my location... although we did hit 49.5 a few days ago.

WTOP was reporting widespread 40s this morning in locations like Manassas...

I never root for 90 degree days... ever.

46 degrees during my run this morning in Montgomery Village, MD. Can't believe we will be back in the heat tomorrow!

Camden - the weatherbug app on my phone says it got down to 47 in Western Loudoun...

looks like you both have some cool temperatures to revel in, at least, before the heat returns :)
