PM Update: Cool and windy tonight and tomorrow

By Ian Livingston

Autumnal conditions return, but weekend looks pretty nice

Humidity levels have fallen and we're headed back toward the type of weather we should be seeing at the end of October. Even though the cold front has passed, cooler air has been slow to arrive, so we've managed another warm day with highs in the mid-and-upper 70s. Things are changing now though, and temperatures will head back toward or below seasonal levels starting tonight.

Through Tonight: It's a breezy evening with temperatures falling into the low-and-mid 60s after sunset. Even though we'll see clear skies, winds stay up through the night, and this should keep temperatures from free-falling out of control. Lows fall to the mid-40s to near 50.

Tomorrow (Friday): With mostly sunny skies the rule, it probably looks nicer out than it actually is. After a streak of warmer than normal days, mid-50s to near 60 for highs are a shade below average. Winds should pick up again -- around 15-20 mph sustained with higher gusts -- during the midday hours. Mixed with temperatures nearly 20 degrees cooler than today, those winds will probably have some bite at times.

Tropics: Even though by definition we've only got about a month left in the tropical season and it's well past its peak, things remain fairly active in the Atlantic (if not near the U.S.). Three areas of disturbed weather, called invests, are roaming the open waters today. It appears possible that we'll see another name or two used in this batch of systems, and the southernmost wave could have the potential to become a solid storm in coming days. The other two invests further north are likely to move harmlessly north, not affecting land as tropical entities.

hah, "free-falling out of control." A little dramatic, aren't we? It's not like we were otherwise doomed to fall into the teens tonight if there were no wind ;)

There may be some sort of mystical meaning attached to the number 79 and it is the record no. of cumulative weeks at #1 on the Billboard charts, held by Elvis Presley. For Elvisophiles, I suppose that's mystical enough.

meteorolinguist, maybe a bit! Dews have dropped a lot though and would probably support colder if winds went calm.

Winds have really whipped up the last hour or two in the city. DCA is gusting past 30 now.

If temp drops a couple more degrees by midnight (likely), YTD DCA Cooling Degree Days will drop below the prelimimary 2,130 figure posted at 5:25 pm on the NWS's Observed Weather Reports page. Hardly matters, since weeks ago 2010 surpassed the previous 1980 record. Hopefully, the new record stays intact for a LONG time.
