Wednesday 12/31: Cool, Clear Rest of the Week; Light Wintry Mix to Rain This Weekend

Wednesday, December 31st 2014 8am

Today: Mostly sunny.  Highs 37-41.

Tonight: Clear and cold.  Lows 18-22.

Thursday: Sunny.  Highs 40-44.

Friday: Increasing clouds.  Highs 45-49.

Saturday: Light sleet, freezing rain, and snow developing during the morning...changing to plain rain showers during the afternoon.  Highs 41-45.

A large area of high pressure over the center of the country will keep things clear and cool the next few days.  A storm system which is bringing rare snows to the higher elevations outside Los Angeles and Las Vegas is expected to eject into Texas before tracking northeast up into the Ohio Valley.  Although this puts us on the warm side of the storm for the weekend, there may be enough cold air at onset for a period of wintry precipitation early in the day on Saturday...yet another cold air damming event with high pressure over New England sending cold air down the eastern side of the Appalachians. Southwest flow will eventually dislodge the wedge changing things over to rain in time for the steadier precipitation Saturday night into Sunday morning.  Right now, I'd say this is looking like another one of those glaze of freezing rain + coating of snow/sleet type ordeals...something we've seen all too often in December.
