Yesterday morning saw the coldest morning since mid-November.  Today we hit 50-55 & as of 8 p.m., temperatures are very mild at 47-53 over the viewing area.

Periods of rain develop tonight with very mild temperatures in the upper 40s to 50s.  A rise to 50-55 is possible.

Periods of rain will occur tomorrow to tomorrow evening before ending briefly as a bit of snow tomorrow night.

Highs tomorrow will run near 50 to mid 50s with strong southwest winds up to 30-40 mph.

Temperatures should tank to 20s tomorrow night-Tuesday morning.  Winds still look strong with gusts to 30-40 mph, but from the northwest.

Overall, 0.50-1.25" of rainfall is possible.

Highs will only run in the 20s Tuesday with breezy conditions with mostly cloudy skies & a few flurries possible.  Wind chills will run in the single digits & teens.

Single digits to teens (7-16) are possible Tuesday night.  Wind chills may drop a bit below 0.

We should turn mostly sunny Wednesday with highs in the 20s & lows in the teens with less wind.

We should cloud over Thursday & be overcast Friday-Saturday.  With temperatures warming to the 40s with a strong south wind, rainfall is possible at times Friday-Saturday. 

Sunday looks much colder with strong northwest winds up to 40 mph with a few flurries with cloudy skies. 

We need to watch Monday/Tuesday & of next week for storm coming from the Texas Panhandle.  What will determine whether we get accumulating snowfall event & how much is up to the position of an Arctic high over the Corn Belt to Great Lakes.  Whether or how quickly system develops into Nor'Easter will also determine snow magnitude here.

We may end up with very little, medium amount or a lot with band of heavy snow possible from the system.  Arctic high is the key to the storm track.

Strong gusty winds of +30 mph are possible with system too.

If we get a good snow pack night following the snow could be a sub-zero to zero one.

After this with highs in the 20s, it looks like all rain Thursday of next week with sudden 40s to 50 with fog (though brief shot of freezing rain is possible north) & gusty winds winds developing.

Bitterly cold air should follow as strong Arctic high sinks southward from Manitoba.  Highs in the teens to 20 are possible with strong northwest winds & a few flurries following this system.

Snow &/or mix is possible from Panhandle system around December 22-23 with track determined by position of Arctic high & how quickly it evolves into a Nor'Easter.

Gusty winds are possible with the system.

Highly-preliminary...............trend is for dry Christmas Eve with sun, light wind & highs in the 20s after lows in the single digits.  Trend for Christmas Day is dry with sunshine, but increasing clouds & a south wind 10-15 mph developing with highs in the 30s after teens in the morning.

With strong southwest winds, day after Christmas may feature some cold rain showers to snow showers as that wind turns to northwest.

After highs 37-44, we may tank to teens at night.

Strong Arctic comes in for December 27-31 period with lows near 0 to single digits & highs near 16-21.

Split flow pattern in the West should continue with more cold than warm here, but some sudden temp fluctuations.

Given this, we need to watch potential storm development in Mexico & then clipper in Alberta dropping southward.

In the first 5 days of January, it appears a strong storm system may form off the Texas coast & phase with clipper bringing wind & potential heavy snowfall here.  However, it could also evolve into Nor'Easter, too, which would trim snowfall totals here some.

Bitterly cold Arctic air should follow with our lows potentially well below 0.

This all a favorable pattern & MJO phase for this situation here & the set-up is found in analog data with a snowstorm coming to fruition.
