PM Update: Showers to end, becoming clear & cool
Showery again Thanksgiving & Black Friday
Showers associated with a cold front moving through the region this afternoon have interrupted an unseasonably mild day. On winds from the south, temperatures had ascended all the way into the upper 60s (69 at DCA). The showers should cutoff by dark as cooler air gradually trickles into the region.
Tomorrow (Wednesday): A much cooler air mass settles into the region from the northwest. That means temperatures about 15 degrees colder than today, with highs only in the low 50s despite sunshine. A wind from the north at 10-15 mph makes it feel even chillier.
Second longest freeze-free period on record: Ian Livingston tells me today marked the 269th consecutive day without a freeze at Reagan National Airport (DCA), the second most such days on record (passing 2001, which had 268 straight days). DCA needs to remain freeze-less for another six days to match the record of 275 days from 1980 (see Ian's earlier post). With the intensity of the Arctic outbreak to the West waning as it heads east, this record may well be in play.
