Max temps yesterday December 23, 2017. Some Wow's out there. 80s in Florida, 50s in Louisiana.





Radar loop last 4 hrs.. I see 2-4" of fresh snow that fell across Illinois, Indiana, & Ohio this afternoon.


Started snowing on Long Island right now. Raining in NYC. Storm now forming off the coast.

if I were back home rather than at my parent's …

Per the HWRF / HRRR / NCAR
ensembles, reason to believe that this band has the potential of
producing 1-3"/hr snowfall rates where snow-ratios modify higher
with the influx of colder air, winds picking up out of the W
behind the band such that considering the fluffy snow we could
be dealing with blowing and drifting, potential for near-blizzard
criteria with white-out conditions.

Snow is expected in northwest MA and north central MA for most
of the storm. The snow may be moderate to heavy at times.
Total snow accumulations are expected to reach 4 to 7 inches in
the Warning area, with a localized 8 inch amount possible
nearest to the Vermont and New Hampshire borders.

forecast upped the totals to 4-8 inches.

The past few GFS model runs have been pretty consistent with bringing frozen precip through Louisiana around New Year's.

The latest NAM even shows a little frozen precip in Louisiana this coming Thursday morning!

I was looking at estimated forecasts for my area (upstate sc) and back north in Cincinnati where I use to live. The low temperatures starting in January seem to be lower than average then I have seen recorded the past few years (10-18F). Up north its even worse -5 to single digits for lows and lots of chances for snow.

Check out International Falls, last 6-7 hours:

National Weather Service : Observed Weather for past 3 Days : Falls International Airport

Now THAT is some radiative cooling. Similar temps earlier in the morning.

(The local airport is a bit of a frost hollow, the town was probably a bit warmer)

interesting it warmed up in the middle of the night. A little bit of wind broken the inversion and mixed in less radiately cooled air
