WEATHER53

33.1 for my high and I was 32.0 or above from 1:45 until 3:20

DCA had three -20 or colder departures in a week which is first time since 1989. i think but dint know last time it happened in Jan or Feb was 1977 or 79 or 82 or 94

DCA averaged -17.4 the last 8 days of January including three -21

DCA still weird as it’s the coldest spot and it was wacadoodle this afternoon with as described above Strong nw winds over frozen Potomac has got to be involved

25.4 for the high here down in the holler at the head of the now frozen creek . 23.5 at 5:30

DCA having a fit this afternoon with an 8 degree increase on one hourly and just now a 5 degree drop on another hourly

What time is this to occur?

This is an arctic siege due to duration length. It’s not a frigid one or two day blast which often sets our records but rather a protracted highs 18-25 and lows 0 to 10.

Low of 11 with minimum hourly wind chill of -4 Any south to southwest breeze influenced warm up is going to travel hundreds of miles over snowpack before reaching our snowpack . It will be interesting to see how that influences milder air attempts starting with tomorrows predicted high temps of 30-33 and 32-35 Tuesday for DC

I gotta get all the data but I think this breaks the record from 1977 for 7 day cold streak

Where is the center of the low? is that it?

7.0 for me and20 at1:45pm

Yes

Green echos lifting due north

94 was extreme and 96 serious business .
