The last week has felt like when I was living in Fargo, it's been great.

The weenies got a taste of meat after feeding on veggie scraps for years and are rabidly hunting for more. Edit: Do I also consider myself in this category. Yes. Don’t @ me.

For everyone’s awareness the Clarksville Mesonet location is in a bit of a cold sink. Not at the bottom of it, but down far enough to have it be anomalous compared to the surrounding area. The Hancock station (-9) is in a park that a stream runs through. Likely colder, but not anomalous of other low areas in the broader ridge/valley region.

Just die (wind)

The snow pack is actually saving the underground water infrastructure right now. Our sub-surface temperature probes have hardly moved post storm. Still safely above freezing below about 4" depth.

Convective feedback issues.

The thing to realize about dew points in this range is that the difference in water vapor between 10F and 0F is between bupkis, and slightly less than bupkis. Once you get down to negatives you're in "absolute bupkis" territory. That is to say that radiational cooling (~200 W/M^2) will absolutely overwhelm whatever tiny vapor pressure is being released by sublimination. Long-Wave radiational cooling will tank the temperatures (and therefore dew points) if given the chance to do so. The only thing that will stop radiational cooling is a blockage of the long wave infrared energy to space (ie. Clouds or Fog).

I remember when I first started tracking these things 84hrs was just getting into "what the **** are we dealing with range" not "ass hair ticks" range. Oh how times have changed, and yet I'd love to still be surprised Jan '00 style.

Takeaways for the 0z runs are that that the globals are still shifting with the northern stream and fairly large disagreements remain. Accentuated by the fact the evolution is very sensitive. Convective feedback / parameterization issues starting to show with the rapid deepening. We wait.

Interesting

H5 is a tick west. Precip is a tick east. No winners though.

Convective feedback issues. It will sort itself in the next few frames.

Dr. No strikes again

Haven't seen him walking around the building this week, I think he's at AMS in Houston.

Two more days of “ Check back in every 12 hours” mode till we close the book for the I-95. Ocean City maybe a day after that.

Winds definitely stayed up last night and prevented the low single digits in most places. Those that did go calm got to the advertised 5 deg-ish fairly easily. Look at all the ice that got pushed to the east side of the bay yesterday to Kent Island.

If the weenies want a bit of a glimmer of hope to hold onto, climatology does not support a surface low that OTS. Pretty rare.

AIFS-Op definitely trending in the wrong direction today.

AIFS is ever so slightly S and E of 18z which is ever so slightly further E of the 12z at 0z Sunday.

Ugh, gonna be a pain to QC all this out. I'm hoping that the wind and sunshine today breaks most of them loose. All iced over.

Locked in on *something* happening nearby. But I agree, it's a bit further east than we would want at this point.

lol.. 977 on Ocean City and a CCB band from the Caribbean

It's legitimately a 36 hr event.

Good god man, there are children who visit this forum.
