I think that's been the case for most guidance.

So I'd favor a hugger track...but it still doesn't make it an easy forecast. The heights crash very quickly and a lot of places flip to snow even on the Euro...so something slightly colder would throw even more of a wrench into the equation.

Though that's pretty much been my rough thinking on this system for SNE...interior like Monads/N ORH county sees maybe some brief ptype issues early on and then flip to snow while the rest of the region goes rain to snow. The Euro is actually sleet and freezing rain to snow over interior this run as sfc temps are below frz there.

But just a tiny little shift in thermal profile could make a decent difference for some areas (like 2 inches vs 6 inches)

Ice to snow I guess is the way to go for us tomorrow. Euro is probably a bit too amped and west ,but no way we'll start as all snow

What was the qpf? i never heard it... I"m guessing on track and NWS discussion that it's similar to the GGEM? BTW, get a load of the RGEM 6z...

EC has us in 0.50-1.00". I don't know what we exactly are, but the 0.50" line is up to BML and the southern end is over the S Coast of SNE. So if someone put a gun to my head I'd guess closer to 0.75". 00-06z Sunday there's a 6hr QPF max stripoe from LEB-here-LCI-PWM.

What would you forecast for SNE as far as ptype from start to finish?

This sounds good to me. GYX was humping the GFS and SREFs. I'll take the Doc anytime over them.

Here's the commentary from ALY. Currently saying, just below advisory-level. Hopefully, those amounts might be higher just to the east of their cwa.

ALL SOURCES OF GUIDANCE SHOW BEST CORE OF

ISENTROPIC LIFT ACROSS POU TO NW CT...WHICH SEEMS IN CONFLICT WITH

BRINGING HIGHER AMOUNTS OF PRECIPITATION FURTHER NW. ALSO...SOME

HILLIER AREAS AROUND POU AND NW CT TO THE BERKSHIRES COULD SEE A

MIX OF SLEET AND FREEZING RAIN...WHILE SOUTHERN LITCHFIELD AND POU

COULD SEE A COLD RAIN WITH TEMPERATURES MAINLY JUST ABOVE

FREEZING. AS IT IS...TEMPERATURES EVEN TO THE CAPITAL DISTRICT AND

SOUTHERN VT SHOULD GET TO OR JUST ABOVE FREEZING. SO SNOW THAT

DOES FALL WILL BE WET...WITH BELOW CLIMATOLOGICAL SNOW RATIOS.

UPPER ENERGY...ISENTROPIC LIFT...FRONTOGENESIS AND BOUNDARY LAYER

WIND CONVERGENCE PREDICTED TO EXIT QUICKLY LATER SATURDAY

AFTERNOON AND EVENING...LIMITING THE DURATION OF PRECIPITATION...

AGAIN IMPLYING THAT PRECIPITATION AMOUNTS WILL LIKELY BE SOMEWHERE

BETWEEN THE WETTEST AND DRIEST GUIDANCE VALUES. WORDING A CHANCE

OF FREEZING RAIN IN SOME AREAS THAT HAVE THE BEST CHANCES FOR A

MIX. FOR AREAS THAT SEE MOSTLY SNOW...GOING JUST UNDER ADVISORY

AMOUNTS...KNOWING THAT WHEN 12Z GUIDANCE ARRIVES LATER

TODAY...BETTER CONSENSUS FROM GUIDANCE WILL HELP ZERO IN ON AREAS

NEEDING ADVISORIES...EITHER FOR AROUND 4" OF SNOW...OR INCREASING

CHANCES OF FREEZING RAIN TO LIKELY...SO STAY TUNED LATER TODAY FOR

THOSE DECISIONS.

Tough one...

I don't like the airmass during the day on Saturday for you guys (even here I may hit 33-35F). I think it would be RA to some snow at the end for the valleys/coast and RA/ZR for the higher terrain transitioning to some accumulating snow.

The airmass is kind of meh for sure. It would probably be one of those 32F flash overs for many, if they do go to snow. I think the higher terrain from ORH north and over to you are fine at the surface.
