A number of reports of sleet mixing with rain Wed. night around Jax & nearby areas.  Amounts of frozen precipitation will be minor, especially for Jacksonville but some icy spots -- especially on bridges & overpasses -- will be possible over Northern & Western Duval & areas west & north.  Temps. had already hit 32 degrees on Jacksonville's Westside by 10pm.
The precipitation will end from west to east by early afternoon, clouds will thin some & temps. will climb into the 40s.  The late day commute should be dry & much better.  We'll stay above freezing Thu. night then our warming trend finally kicks in Fri. & especially over the weekend (see the 8th image below).

From our Jax N.W.S.:

Pink shading is winter storm WARNING... :

The illustration below show the temp. profile for freezing rain vs. sleet vs. snow.  Freezing rain is rain that falls through a warm layer throughout most of the lower atmosphere but freezes upon impact when surface temps. are at or below 32 degrees.

From "Earth Gauge":

Big warming trend!

Indications are that our upper level weather pattern will undergo some serious "adjustments" next week.  The polar jet stream will become oriented more west to east.  Very cold air will still be in place across the Northern U.S. while warmer, more humid air spreads into the Southern U.S.  Upper level disturbances -- some strong -- will be driven west to east by the jet stream spawning several surface cyclones -- each one potentially producing "significant" weather.  On the cold side of the cyclones will be heavy snow & ice.... on the south/warm side will be heavy rain & thunderstorms.

For the First Coast... this pattern will result in generally warmer temps. with some rain from time to time & possibly a few t'storms depending on the location & strength of the surface cylcones (low pressure).  There will be temp. drops when cold fronts move across the area, but the progressive pattern should not allow the cold air to become well entrenched (such as this week).
