Here's a new near term update:

.NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/...

WATCHING SFC PRESSURE EVOLUTIONS CLOSELY FROM AL TO THE GA COAST

THIS EVENING...DUAL LOW STRUCTURE IS FURTHER NORTH THAN 18Z

GFS/NAM AND SIMILAR TO 12Z ECMWF...AND EVEN FURTHER NORTH THAN THE

NEW 00Z NAM12...BUT THE NAM IS CATCHING UP. RESULTING NAM12 RUN

PRODUCED A LOW TUCKED CLOSER TO THE COAST LOCATED NEAR THE

CHESAPEAKE AT 00Z THU...SUPPORTIVE OF THE POTENTIAL FOR HEAVY SNOW

(6" OR MORE) IN AREAS WHERE WINTER STORM WATCHES ARE CURRENTLY PLACED.

WINTER WEATHER ADVISORIES FOR SNOW ARE SOLIDLY IN THE 0.25 TO

0.35" QPF TOTALS. WHAT WILL BE INTERESTING IS TO SEE THE

OPERATIONAL GFS AND GEFS MEMBERS...AS THE NAM HAS BEEN ON THE

DRIER SIDE OF SOLUTIONS FOR THE PAST SEVERAL DAYS. AS PER COORD

WITH WFO MOUNT HOLLY THIS EVENING...WILL KEEP ALL HEADLINES AS IS

FOR THIS EVENING AND ALLOW THE OVERNIGHT SHIFT A GOOD LOOK AT THE

00Z SUITE TO MAKE THE BEST WARNING DECISION POSSIBLE FOR WEDNESDAY

AFTERNOON AND NIGHT.

TIMING OF ONSET OF SNOWFALL STILL LOOKS GOOD...BREAKING OUT AROUND

OR SHORTLY AFTER 12Z WED ALONG THE MD BORDER IN THE LAUREL

HIGHLANDS AND SOUTH CENTRAL MOUNTAINS. 20 OR 30 POPS WILL BE

RETAINED ALONG THE SRN TIER BEFORE 12Z...WITH SUCH LOW POPS...NO

ACCUMS EXPECTED IN 1ST PD.

Aside from the actual obs being even further north of the new NAM, another thing I see is it may be shortchanging precip a bit as well. We're already have a pretty nice radar as well as a good push north so far. If the other new models hold serve or come back NW a lil bit CTP will probably at least get advisories up another tier or so.

GFS continues to shove that thing off the coast, i'm actually surprised with its low track that it got the precip it did into the southern half of PA. I still like the 12z ECMWF track and precip evolution to this system. In the meantime i'm hitting up the snowboarding IMBY, be back in a bit :snowman:

The ULL is over southern MD not sure why it is all whacky.
