NAM is mid-20s at the surface during the morning quick hit of snow.

Lost the column by 15z in DC, but at least some front-end snow.

Back to weather. That sim radar for the NAM looks very spring like. Should be lots of CAPE available 

There is lightning showing up tonight SW of Richmond.

3k NAM. This is the sounding at DCA (top) while the sim radar looks like that (below).

The 3km is a front end thump DC and north.  Nearly 0.3” in 3 hrs, apparently snow and 28-29 degrees.

15z on Thursday - 90kts at 700 blasting through on the NAM.  Not so much on the GFS.

Absolutely wild

The NAM is strengthening the primary in Ohio.  That’s not what we want.

Lol.  DCA ~6hrs into precip

Mike Seidel was on I-20 in Monroe, LA and compared it to the NY State Thruway in the lake effect belt. 100 yard visibility in heavy snow. I’ve never seen anything like that in my life. This storm is amazing.

It is a convective band that is pouring snow.  Fantastic.

It’s interesting how these crazy cold shots come down so far south in the middle of the country. I would think that the Gulf of Mexico would help moderate temps in places like Houston, but apparently not or not always? 

I read recently that in 1895 there was snow as far south as Tampico, MX. 

Seems like the Atlantic (or maybe our longitude) is our worst enemy here in the mid Atlantic 

Both the Atlantic and the Apps.  Expansive cold air outbreaks are often shallow.

lmao south TX is going to get more snow than DC this year (and definitely going to record a colder temp).

It is colder in Houston right now than it has been at DCA for years.  This is amazing stuff.

Snow and blowing snow at DFW right now and 11 degrees.  Wonder what is the last time DCA had an ob like that.

Damn

 

I’m always skeptical of those obscene ratios unless they are doing a snow core measurement.  If they are comparing to a heated ASOS bucket I toss.

Can you locate our problem here?

Everything?

0.41” precip.  That is a ton of frozen.

Skating rink on the sidewalks out there this morning.

There are 400k Dominion Energy customers in Fairfax County.  One poor sap is without power right now.

Sure enough, sun went down and it all froze up nicely.  There is the faintest breeze, and you can hear the trees crackle.  27.3 and freezing drizzle.

Just took a walk with the dog.  Sidewalks greasy but not slippery, if that distinction makes sense.  There is a glaze on all elevated surfaces, but nothing significant.  Maybe 1/8”.  This would have been a big deal if it happened overnight.

29.2

Pretty much sleet now.  27.7

Most icy thing I could find.  27.7.  72 w/m2 solar.

27.7 and ZR, but this is really low-impact due to the sun angle.  Little accumulation on the wires or trees.  Sidewalk is wet.  Metal surfaces are certainly icy.

28 in Burke with drizzle and a bit of sleet.

Almost fell on my arse when stepping onto the deck.

The sleet is providing a bit of grip!  28.6

Sleet and ZR started a bit ago.  28.9/22 so the temp will probably fall a bit.

At some point you just have to marvel at it.

All hail King NAM.
