Interestingly, the zfp even for here in western Franklin has a sleet taint on Wednesday. BOX is sticking with a mix scenario in their AFD.

Nice to see 4-6" in the official forecast for NW areas from the appetizer.

Doesn't really matter what the AFD says.Everything is coming in much colder/south and snowier Mike,. Euro/NAM/GFS ..look at trends..not AFD's

I'm not sure that extra inch over 24 hours would merit exclusion--especially since we're talking "watch" and the confidence level has to be quite high. I wonder if VT has the same criteria as they've been hoisted there.

Read the AFD it's explained in there also IIRC.

PER COLLABORATION WITH UPSTREAM OFFICES AND BASED ON MEETING WINTER

WEATHER CRITERIA...HAVE ELECTED TO ISSUE A WINTER STORM WATCH

TUESDAY THROUGH WEDNESDAY NIGHT FOR MUCH OF THE AREA...VERSUS AN

ADVISORY TUESDAY AND WATCH FOR WEDNESDAY...AS THE LULL IN

PRECIPITATION INTENSITY TUESDAY NIGHT IS EXPECTED TO BE BRIEF.

THE WATCH WILL LIKELY BE EXPANDED NORTH INTO NEW HAMPSHIRE THIS

AFTERNOON...GIVEN CRITERIA THERE IS NOT EXPECTED TO BE MET THERE

UNTIL LATE 4TH OR 5TH PERIOD. WILL HIGHLIGHT POTENTIAL EFFECTS AND

NOTE IMPACTS OF THIS TWO PART SYSTEM IN THE WATCH STATEMENT. THE

WATCH MAY BE EXPANDED CLOSER TO THE SOUTH COAST AS WELL...ALTHOUGH

WARMER AIR IS EXPECTED TO CUT DOWN ON SNOW AND ICE ACCUMULATIONS.

I see that, Kevin. My comment was tied to their AFD not seeming to really give that a whole lot of weight for whatever reason. Either way 12+ looks pretty good.

I mentioned this yesterday, but I'll do so again. I would think the duration of this over two days will allow for some compaction of snow during the events (even without tainting). So, folks should take that into account when putting out their accumulation forecasts.

Won't matter if wiping the board clean every six hours.

I don't know, would think the two systems should be measured and accounted for seperately if there is an extended break (several hours) in precip.

Also, everyone shuold be wiping clean their measuring boards/surfaces every 6 hrs which negates the compacting issue.

Not enough meridonal flow for the weekends system to catch it seems. (OT)

You are qyuickly becoming the latest DD. All this talk of wanting zr and storms missing.

SATURDAY...

NO REST FOR THE WEARY. ANOTHER SYSTEM BURSTS OUT OF THE GULF OF

MEXICO AND UP THE EAST COAST. BOTH THE GFS AND EC OPERATIONAL RUNS

AGREE ON THE SURFACE LOW MOVING PAST NEW ENGLAND SATURDAY

AFTERNOON/EARLY NIGHT WITH A FEW DIFFERENCES IN TRACK AND TIMING

DETAILS. THE GFS IS FASTEST AND DEEPEST...AND SHOWS A PRESSURE FALL

OF 24 MB PER 24 HOURS FROM 12Z SAT TO 12Z SUN. BOTH GFS AND ECMWF

THERMAL PROFILES WOULD BE MAINLY SNOW...WITH POTENTIAL FOR RAIN/SNOW

MIX ACROSS THE ISLANDS.

OF COURSE...THIS IS A DAY SIX FORECAST SO EXPECT CHANGES AS THE

EVENT GETS CLOSER. FOR NOW THERE SEEMS ENOUGH AGREEMENT ON A SYSTEM

CLOSE ENOUGH TO AFFECT MOST OR ALL OF OUR AREA SO THAT WE WILL

MENTION CHANCE POPS IN ALL OF SOUTHERN NEW ENGLAND. HIGHEST POPS

WILL BE ON THE CAPE AND ISLANDS AND LOWEST POPS AT CHESHIRE AND

FRANKLIN CO/S. WE WILL USE A BLEND OF GFS AND ECMWF THERMAL

PROFILES TO GENERATE P-TYPES.

SUNDAY...

HIGH PRESSURE BUILDS OVERHEAD WITH MARGINAL COOLING OF THE AIRMASS.

EXPECT FAIR/DRY WEATHER WITH SEASONABLE TEMPERATURES.
