Everyone have a very Merry Christmas!

Patchy light snow, drizzle & freezing drizzle is gradually exiting.  Liquid amounts should remain trace-0.01". Very little to no snowfall accumulation is expected.

No White Christmas :(

Clearing trend will occur today with highs 38-45.

Widespread rain should come in Thursday with the potential of an isolated rumble of thunder.  Highs will be mild in the 50s with gusty winds.

Dry slot should come in Thursday night-Friday morning with clearing, before actual cold front brings line of showers Thursday morning.

After initial highs in the 50s early Friday, temperatures will fall in the afternoon as low clouds rotate in on gusty northwest to west winds.  Temperatures will fall through the 40s.

A few flurries & snow showers are possible Friday night-Saturday.  Saturday's highs will only reach 29-33 after lows in the 20s to around 30 Saturday night.

Next system to watch is around New Years period.

With cold air in place, it would tend to be mix &/or snow.

Arctic high with bitterly cold air should dominate after New Years period.  Cold air will be sufficient for potential of icing/snow episode to nearly the Gulf Coast of Texas, Louisiana & Mississippi to eventually Alabama to near the Panhandle of Florida.

Our highs in this cold snap may only run in the teens to 20s with lows potentially below zero (especially if we can get a snow pack).

The dry, bitter cold may moderate quite a bit suddenly & briefly around January 7-8, followed by potential mix to snow around January 9-10.

Bitter Arctic air should follow.

Highs in the single digits & lows well-below zero are possible.

We will have multiple opportunities for snow & ice mid to late January.  A big Nor'Easter or two is likely in the Northeast, too.

The CFSV2 models is finally coming around, seeing the cold coming.

Look at the lobes of bitterly cold air coming in during January.

The worst may be after January 15.

 actually do agree with this in the CFSV2 model.  Big Arctic warming episode will translate to a "Polar Vortex" type episode over all areas east of the Rockies.  Temperatures 20 to 40 degrees BELOW NORMAL for the central, southern U.S. to northern Mexico are expected.

Highs in the 30s may occur in far south Texas & northern Mexico, damaging winter crops there. The worst of the cold may miss Florida, but it looks record cold in growing areas of far south Texas & into Mexico. This "Blue Norther" will likely ride the Mexican coastal plain, all the way to near the Yucatan.  Very impressive!

Look at that January 1994-style Arctic high in latter January!

Check out the projected record snow in south Texas & northeastern Mexico with ice to the coast!  Wow!

Although it is likely that temperature moderation will occur for a period as we wrap up January with a thaw, bitter cold should return in early February.  February should be the coldest, snowiest month of the three-month winter period.

Here is what to expect overall (there will be ups & downs, but overall cold, cold) January-March as a whole...........then ApriMay (temperature-wise compared to normal):
