Today: Sunny a.m., partly cloudy p.m. 55-59. | Tonight: Clear and chilly. 30-36. | Tomorrow: Sunny. 51-55. | A Look Ahead | Get Express Forecast by E-mail


Another beautiful stretch of weather will have us forgetting all that blowing and crashing of the past day in short order. The mild, dry conditions allow all of you well-prepared cooks to get in those grocery runs for next week's Thanksgiving feasts. My only question is will downtown DC, including Reagan National, ever hit the freezing mark? It is already two weeks late and right now it looks like it will take until Thanksgiving weekend!

Today (Thursday): Sunny skies allow temperatures to pop up into the 50s fairly quickly. However, a dying storm born in the Plains yesterday passes over in the afternoon with a fair amount of clouds probably stopping us from hitting 60 in most areas. Winds from the west at 5-10 mph feel like zephyrs compared to the day before. Confidence: High

Tonight: Quickly clearing skies in the evening allow readings to return to the 40s. The real chill comes later with overnight lows to hit lower 30s outside the beltway and mid-30s inside. Confidence: High

Keep reading for the forecast through Monday....

Tomorrow (Friday): Bright sunshine should not be challenged on this day. The heart of the high pressure and cool air mass are on top of us. This slows the upturn in temps with highs only in the low-to-mid 50s. Breezes remain light from the north. Confidence: High

Tomorrow Night: Calm winds take some of the bite out of the chilly temperatures but 40s rule the evening. Cloudless skies prevail. Frost is reserved for only the far out suburbs with lows ranging throughout the 30s. Confidence: High


Saturday is a beauty! Sun filled skies and highs in the upper 50s to lower 60s beckon us all to the outdoors. The evening should be a fine one with readings holding in the 50s. That should keep the Terps fans from getting too chilled as if that would happen with Florida State in town. Confidence: High

Sunday dawns chilly but manageable with mid-30s to lower 40s. A cool high pressure system slips south out of Canada into the area. The only impact is a slight upturn in northerly breezes and drop in temperatures. Highs still peak in the mid-to-upper 50s. The clear evening makes it a treat to look up and see the full "Frost" moon rising in the company of Jupiter. An even greater treat for the early risers is brilliant Venus and Saturn in the predawn. With lows only in the upper 30s to lower 40s, it's worth it. Confidence: Medium-High

Monday has a sunny start but a few clouds begin to sneak in from a Midwest storm system later in the day. This does nothing to dent the rise in temperatures. A building breeze from the south pushes highs to the low-to-mid 60s. Confidence: Medium-High

Based on the "two weeks late" comment above, I take it DCA's average first freeze is approximately November 4? I guess I thought it was a little later than that...

Hi MKoehl - let me first link you to a previous discussion of this, from earlier this season:

I am looking at the data and can arguably believe the first frost at DCA (median number) is today. I believe David is evaluating long-term averages, instead of the last 10 to 30 years, during which all our region's first frost dates.. have advanced later into the season (about 1 week).

The later the freeze date moves later into the season, the longer "The Glover Park Stink Bug Massacre" Smell-o-Vision flick plays. Two months; long enough, already!

re: freeze dates--

Ian's dived into the data and we'll have an in-depth post on this in the next few days.

@Jason, hope Ian will include inforation re: how low temps need to go to kill off the stinkbugs.

I guess this is more for the mods. Given the recent issues with the message boards, do you know of any other message board sites like those? With the first vague hint of snow somewhere in the future, I need to get my weather overhyping fix in! Thanks!

inadvertent double post above, due to system error msg.

So that big bright planet we're seeing in the early evening is Jupiter? I'd been wondering.

I saw no meteors this early a.m., not that I craned my neck for very long. Funny thing, I see one almost every night of the year when I gaze for 10-15 min., but seldom have I spotted even one during a reported meteor shower. The Perseus shower in August is a hopeless case--the summer sky is murky even in Jefferson County.

Nautachris23, here is the new version of the weather board!

It's normal not to have freezing temps for quite a while down here inside the Beltway. During a few mild late falls I've heard crickets chirping as late as Christmas or New Years--generally only the small ground crickets.

Here's a global warming cite: In the latest Journal of Geophysical Research, Russian scientists Vladimir Petoukhov and Vladimir Semenov correlate REDUCED sea ice in the Barents Sea and Kara Sea with more severe winters in continental regions. This seems "good" for everyone: the Russians get more ice-free Arctic port facilities, and WE get more "Snowmageddons"! Evidently warmer Arctic water in winter results in more Greenland blocking, resulting in more cold air sent towards Washington.
