Pretty much the same.

Check out the HRRR snow map I posted. It's still snowing at that point too.

well as Canderson has said a couple times, i'd much rather have that snow then ice.

Their not making out so well with their Prog highs are they? Seems like in the other fo's they too are failing......

Does anyone have an idea what we'll see In Eastern Lycoming county? Usually I can keep up but with this storm I have NO idea lol.

yeah, these models have been terrible on this one, esp the NAM. I would say 1-3 of snow , then an icy mix till mid morning. then light rain showers for us. high in mid 30s seems rite. thats all just my guess for us bro.

COASTAL SFC LOW CENTER DEEPENS AND LIFTS NORTHWARD ALONG THE MID

ATLANTIC COASTLINE LATE TONIGHT AND TUESDAY MORNING...LIFTING

NORTH OF THE OUTER NC BANKS BY 12Z TUE. MOIST AND MILDER ATLANTIC

FLOW WILL OVERRUN COLD LAYER AT THE SFC AND BRING A VARIETY OF

PRECIPITATION TYPES INTO THE LOWER SUSQ. BETWEEN 12Z AND 18Z...

WITH A CHANGEOVER TO PLAIN RAIN LIKELY OVER ADAMS...YORK AND

LANCASTER COUNTIES. FURTHER NORTH...A PERIOD OF FREEZING RAIN WITH

ICING IS LIKELY BUT AT THIS TIME THINK AMOUNTS WILL REMAIN UNDER

0.25" AT PLACES LIKE SCHUYLKILL COUNTY. MODEL TRENDS HAVE BACKED

OFF ON THE WESTWARD EXTENT OF HIGHER QPF...AND THIS IS ANOTHER

REASON TO HOLD ONTO AN ADVISORY FOR NOW VS. THE WARNING THAT WILL

BE HOISTED IN HIGHER QPF AREAS TO THE EAST.

OPTED FOR AN EARLIER START TIME TO THE WINTRY PRECIPITATION AND

HEADLINES THIS EVENING...MOVING UP START TIMES OF EXISTING WSW

HEADLINES TO 00Z...AND EXPANDING WEST AND SOUTH IN COVERAGE TO

INCLUDE SOME CENTRAL MOUNTAIN AND LAUREL HIGHLAND COUNTIES. ONCE

PRECIPITATION SLACKENS OFF ON TUESDAY...IT`S QUITE LIKELY THERE

WILL BE AREAS OF FREEZING DRIZZLE WITH COLD AIR TRAPPED NEAR THE

SFC AND A SATURATED BOUNDARY LAYER BELOW CLEARING MID AND UPPER

LEVEL SKIES. MAX TEMPS WILL OCCUR LATE IN THE DAY...AND MAY STILL

BE ON THE MILD SIDE GIVEN CLOUDS AND PRECIPITATION. MOST AREAS

Warning for Berks County. ARGH! CTP!

Yeah, when you have this issued for a northeast bordering county, it certainly is a head-scratcher. Maybe we can succeed from CTP and join PHI.

Saw Weather World had 3-6" for much of Central PA, from Harrisburg to the Allegheny Front north to the NY border, then over to NEPA and back down to near Harrisburg. Mentioned a sharp cutoff on the western edge west of State College...hopefully we'll end up on the right side of that cutoff. :snowman:
