MN Transplant

The GFS has outperformed the Euro on temps for the globals, and the NAM has been much better than the HRRR. One thing that I noticed that was not surprising was that the AI models did not handle the wind gusts well. They were too muted, as is to be expected with more extreme events.

Peaks gusts at the airports DCA: 58 BWI: 57 IAD: 52

43mph on my anemometer through the trees ties my top gust since 2021 (localized microburst). We probably won't see the near 60mph number that the NWS was saying was possible, but this is an impressive event.

12/5 - 1.9" 12/14 - 1.3" 1/26 - 8.5" 2/6 - 0.2" Total - 11.9"

DCA to 54mph. My backyard is littered with sticks.

Coldest wind chill I can find in the broader region is Bradford, PA (NW PA) at -35F within the last 30 minutes.

The three airports have already gusted into the upper 40s. Temps are still dropping. Pretty nasty out there.

Peak wind gust IMBY: 12z Euro: 54mph 18z HRRR: 50mph 18z NAM: 46mph 18z HRDPS: 56mph

Ground is whitening. Might squeeze out something measurable.

Lazy flakes. 29.2

My NWS point-and-click has a 60mph gust for noon tomorrow. I'm not sure I've seen something like that since the big March windstorm in the late 2010s.

Consider them the outlier right now. Probably a bit too cold. Mid-teens in the afternoon is a better bet.

We are going to ruin a top-tier cold day on Saturday with a midnight high.

Here's a fun one - the last time that DCA (current airport location) had a consecutive week below freezing with at least 5" of snow on the ground was...never. 1989 had a longer streak, but less snow on the ground (2-4") 1979 had a similar streak, but some of the days had 4" 1961 had a 13 day stretch where it hit 33 twice (3-9")

Road trip to PA?
