Forecast: Heat Hangs on Through Tomorrow

By Dan Stillman

Cooler and somewhat unsettled starting Wednesday

* Severe Weather Site for Kids | Later: Heat = Weather Whiplash *


Today: Sunny and hot. 89-93. | Tonight: Clear and mild. Upper 50s to low 60s. | Tomorrow: Mostly sunny and still hot. Upper 80s to near 90. | A Look Ahead


It was just on Friday that the morning low at Dulles Airport dipped to a crisp 36 degrees. Fast forward to today and we're looking at a third straight day of highs near and above 90, with a near repeat performance on tap for tomorrow. Wednesday through Friday, temperatures step back to more typical levels for this time of year, and the chance of scattered showers and thunderstorms enters the picture as well.

Today (Monday): The difference between today and this past weekend?... only that most of you will be stuck inside at work or school as temperatures rise once again to highs in the low 90s in most spots. Skies stay sunny and an afternoon breeze picks up from the south around 10-15 mph. It'll be a busy day for those office A/C units. Confidence: High

Tonight: Just a great evening to spend some time outside as temperatures drop through the 80s and into the 70s. We'll keep mostly clear skies through the night with morning lows in upper 50s (suburbs) to low 60s (downtown). Confidence: High

The forecast continues after the poll...

Keep reading for the forecast through the weekend....

Tomorrow (Tuesday): Our heat streak reaches day 4 with mostly sunny skies and highs in upper 80s to near 90. Take some time to soak up the sun and feel the warmth -- this will be the last of our mid-summer-like heat for a while. Confidence: High

Tomorrow Night: An approaching cold front brings a 25% chance of a shower. Under partly cloudy skies, it's another mild night with lows in the upper 50s (suburbs) to low 60s (downtown). Confidence: Medium-High


The heat wave comes to an end Wednesday and Thursday, when highs will probably top out in the upper 60s to mid-70s under partly cloudy skies. Scattered showers and thunderstorms are possible (40-50% chance) through the period, thanks to a cold front that will stall out upon reaching the area. Wednesday and Thursday night lows should settle in the 50s. Confidence: Medium

A more powerful cold front could bring a period of more widespread showers and stronger thunderstorms on Friday, as well as breezy winds from the south. Highs should be somewhere in the 70s to near 80. Confidence: Low-Medium

The weekend forecast is uncertain at this point. If Friday's cold front is slow to move out, then we could see come clouds and shower chances lingering into early Saturday. Otherwise, one scenario leaves us partly to mostly sunny for most of the rest of the weekend, while another scenario brings the next shower-maker in as soon as Sunday. Best guess on high temperatures is in the 70s. Confidence: Low

Love it. Have been waiting a long time for this type of weather again!

Nicer if they had switched over the A/C in my apartment complex. It was pretty stuffy in my room this morning. I cracked open a few windows but I think that will only help with air circulation and not the heat (sigh...)

I love the heat, and love the final entry of late-spring/early summer from the dreariness we had been having, but I wish those pools were open. A/C is not working in the house right now, so last night was a sticky/hot night. Oh well, i'll take what I can get

All I know is that my black car now looks like a yellow submarine.

Too hot too soon... and too much pollen!

You guy's are in a heat wave and we have a month of flooding. This weather is extreme.

Not liking it one bit. No time to adjust to the heat and humidity. I call this a big FAIL.

I love it! I feel so energized now after all those cool, cloudy days earlier in the month.

My hair, on the other hand, is going a little spastic from the sudden humidity.

It probably helps, psychologically, to know that temps will be cooler later this week. I might be a little less of a heat cheerleader if we were predicted to have highs in the 90s indefinitely. But since we're not, it just feels kind of nice.

It IS too big a swing at once. We should get cooler weather about Wednesday which will last several days.

Tonight's dance looks okay, but these are mainly swing dances with an occasional disco or rock and roll dance mixed in. They are not supposed to be rain dances, but that's apparently what the anti-Bombo rain dance conspiracy has in mind. There was a thunderstorm Saturday night while we were all safely INSIDE the Glen Echo Spanish Ballroom. Friday's dance looks rainy and it's possible tomorrow night. However the rain expected from Wednesday through the weekend will generally involve stable air so will be more gentle and less convective.

Out in the Midwest they are getting plenty of rain, but food prices may go up anyway. They are getting too much rain, the ground is soggy and farmers can't plant their crops.

Otherwise, the swine flu outbreak is making headlines. This is supposed to be the tail end of flu season, so we don't know if it will take a break for the summer but there won't be a vaccine for this strain for 2 years or more. Mexico City just had a 6.0 earthquake and that combined with the swine flu could make the disaster worse.

what happened to spring???

Posted by: madisondc | April 27, 2009 2:02 PM | Report abuse

I think it's quite nice out. Warm, but the humidity it only 37% and a nice breeze. Much better than the 90 degree weather we get in July with 87% humidity!

What are the chances of a shower during the Nats game Friday? It'll be my first of the season and I'm really hoping for good weather (we have good seats!).

Posted by: sillygoose22 | April 27, 2009 3:50 PM | Report abuse

I hate this weather. I hate it in July, when it is more or less seasonal, and I REALLY hate it in April, when it isn't at all. What's wrong with a high of 70? Much nicer than 95. Especially in April.
