RADAR returns are looking a bit moth eaten - AND the precip still has to traverse the App's.

SREFs kind of acting "jumpy"

If we are to get the 2" as shown by NAM, that shotgun blasted precip shield had better be a thumper.

Check out the rainbow top.

Circled in red is the sea surface temperature gradient associated with the Gulf Stream

And potentially the nascent low just south of it, over the bath water.

BTW - for those wondering, it stated snowing on UTS Hill - 10 minutes ago.

It seems as if the preceding warmth is going to inhibit immediate accumulation.

Best part of the GYX disco, rain or snow, should be an impressive meteorological display. smile.gif

QUOTE
.SHORT TERM /TONIGHT AND FRIDAY/...
Surface low bombs out, dropping 20 mb in six hours this evening.
Forward speed of system and strong wind fields will allow a couple
hour period of very strong winds for the Midcoast Region this
evening. Expect winds of 50 kt out of the southeast ahead of the
landfalling system which will be just west of the Midcoast. Have
therefore upgraded the wind advisories to high wind warnings over
Knox and coastal Waldo counties where best low level jet will
likely enter the region in the proximity of the coastal front.

Ptype: Warm air will quickly press northward, with the
coastline changing quickly to rain with the passage of the coastal
front this evening. Significant instability just north of the
approaching dry slot will allow for thunderstorms to develop and
head northward through Maine and eastern New Hampshire.

There continues to be a strong signature will all of the models
suggesting banded precipitation this evening. Snowfall rates will
be 1 to 3 inches per hour at this time with periods of
thundersnow. During the 03z-06z time period, mesoscale models are
suggesting that some of this precipitation may wrap back into the
coastal regions, possibly changing back to snow.

.SYNOPSIS...
High pressure over New England moves offshore by morning.
Low pressure moving across Canada will cause a strong cold front to
pass through our region this afternoon. Low
pressure develops along the Mid Atlantic coast Thursday and
rapidly intensifies as it crosses Eastern Massachusetts Thursday
evening, bringing heavy snow well inland and mainly rain along the
coastal plain.


State College getting moderate snow right now.

Here's a look at the temps for the stations not reporting anything ahead of the moisture

Starting to see a thin coating on most surfaces now.

One thing I noticed - at least for here -- no virga what so ever. What you see on radar is prob what you'll get

Haven't really used the RAP, but for those who may like it, looks right in que with other modeling.

Rates have quickly overcome relatively warm surface.
All surfaces whitened - grass covered, stone driveway covered. Only like a half inch by eyeball, but not bad for essentially 45 min's of precip

I'm not sure if it works the same on all devices, I use a tablet or phone and do it by clicking (tapping) on the map where I want to see on this page

http://radar.weather.gov/Conus/northeast_lite_loop.php

That opens this page

http://radar.weather.gov/ridge/radar_lite....N0R&loop=no

You need to make sure it is in "standard version" (or at least I do)
