Definitely getting an increase in ENE winds now despite similar sky conditions. Down to 44.7

Jeez, you have been warm for hours, my Davis hit 43F/ now showing 37F, light wind.

Likewise, 37/31 light east wind down 2 each in last hour.

You’re going to need a good, sustained push of CAA in the zr zone because of latent heat release. 3-5” in the max sn zone looks good to me…either side of an AFN-BVY line. If there’s a junk +1C layer aloft that could wreck havoc on the southern end of that if you’re battling junk precip for awhile.

Is there even any ice threat anymore ? Hope it’s not totally over

Im thinking ORH hills south of rt2 might be the best bet until they flip to sleet/snow

That’s a really bizarre sfc temp map for early March

I'd say!

The new HREF is going to have to fail miserably with the amount of zr it has south of pike in NE/ NW CT hills into N RI

Very breezy in Chelsea when I left work...right next to KBOS

Looks great to me!

Nothing scream busting colder right now. 
 

Not overly impressed with the dewpoints yet in SE NH/E MA. PSM is 29F dew. Need that at least 4-5F lower. Or at the very least, 2-3F colder with a corresponding SFC temp drop so that it’s the same difference for wetbulb…if we’re trying to bust colder. It’s fairly close to most guidance.

the problem is how much QPF you waste before dropping below freezing

Your area has been warmer than the coast all day.  Kind of like April and May

Dews have climbed here in N ORH county.  KFIT at 33 now

KFIT is prob kind of fake because they radiated so well earlier. ORH has been rotting at 29F dewpoint for hours....briefly spiked to 31F when rain moved in, but fell again when it tapered. 

[rimetree]

Down to 35/31. 18z HRRR drops 4" or so here.

Their dews are always too low no matter the season . I check it daily. Typically 3-5 lower than all surroundings

They’re slowly advecting through Rockingham county now.

FIT or ORH? Typically ORH is gonna have lower dewpoints because of the elevation difference. But if you’re a rad pit, you may start off the day artificially low because of extra moisture that was lost from the atmosphere when you condensed frost or dew.

ORH. It’s very noticeable in summer but even in winter . They’re usually lower than everyone else at similar elevations. I’ve brought it up on here before

Nam is a cancel for most. Probably the right idea.

I mean this is either going to break some grids or fail terribly . New HREF

It’s usually decent .. but I don’t think so this time

NAM is a scalping to a crusty inch or two here. Meh.

There’s your micro +1C layer. That’s dangerously close to a thump though.

3k is like 4-5” here

NAM looks alot better than 12z for central NH.
