Around the 23rd I posted that 1/7 time frame would bring back the cold. Some coastal action portrayed also and within 7 model days, 3-5 still the best indicator, of event which matches analogs.
Jan 5th to 8th fits the two week oscillation pattern we are under so models showing storminess and/or cold will likely be right this time.
Maybe we can even get a meandering low along the coast
40 for a high but just 33 13” off the ground. Ground still frigid and should radiate out colder temps overnight than forecasted. The only exception is that one station that somehow doesn’t radiate out.
DCA set a record at 22 breaking 23 from 1989.
IAD tied at 22 also from 1989
BWI tied 20 from 1880’s.
Average daily at DCA of 15.75 is also a record for Christmas Eve
It’s not winter rarity but we are in a 2 week oscillation pattern . Gets mild after this and then turns cold about 1/7 and that push looks like very cold air pouring down on us from PA/NY instead of rollover cold from Midwest
Yes this is not the top but it’s number 4,5,6 or something. I did not break my records for 1,3,6 hour drop rate but with 54 at midnight I’m going to break my 1983 record of 40 degrees in 12 hours.
14.5 at 6:30 and definite slick spots driving around here Need to be alert to this is not a typical night and if you see shiny you are not seeing things, it’s ice
