Why? Just curoius?:) It actuall looks fairly good for the Boston Area.

Because those warm layers located high up always like to ruin the party. It's going to hit the D-Line right near the Pike, but it's precarious in my area. I didn't see any significant changes to my thinking. Hopefully we get over 6" new, but not so sure. Sticking with 3-5" for here. 5-9" for Ray potentially.

Looks like Vince Wilfork sets his azz up on Rt. 2 and pushes.

My 700mb temps warm to a saturated -2C in the heart of the "blitz" tomorrow morning. :lol:

NAM goes gangbusters up here 12-18hr. Hopefully I hold off the pings. :lol:

Was hearing earlier that we risk an H7 dryslot. It is generally good though to be just north of the changeover line as get maximum lift is that? I wonder who will get the best deform and ratios. I looked at 18z bufkit and our ratios suck and we only get 10 inches.

They're talking 2-event total. Note this disclaimer from GYX:

EVEN THOUGH WE HAVE TREATED TODAY/S SNOWFALL EVENT AND WEDNESDAY/S

AS SEPARATE EVENTS FROM AN ADVISORY/WARNING STANDPOINT...OUR SNOW

TOTAL GRAPHIC ON OUR WEB PAGE REFLECTS THE COMBINED TOTAL FOR BOTH

DAYS TO BE CONSISTENT WITH SURROUNDING OFFICES.

That's the old AFD. New one states new map shows Wed storm total.

They Must have meant Total. Not for the period that it's written for. But if you just read it, you'd think 8-12 is coming between 1am-10am! HaHa. Not written well.

700mb temps are warm for a lot of us. Even far NNE. BTV and BML get up to -6C/-7C at H7 too. I'm not liking the ratio potential until we get into hang back precip.

I like again that you're being very honest with your concerns..big help to all.

If I had a gun to my hotdog, I'd forecast 2-4" for Boston proper, 3-6" north, nothing to 2" south just off the NAM and RUC trends.

RUC continues to torch more later after the initial CAA. When the NAM had us comfortably in the snow today the RUC had us toasty....

Don't let the guys obsessing over every 1\10 of a mile change on the NAM and RUC upset you.....these swfes with strong highs play out the same way just about all of the time.

Yeah, it's going to rip like gangbusters from like 9z to 18z and after that there may be some crap. 10'' here we come.

Hey, 3-5"...just what I was thinking.
