The two big stories for today are 1) Wintry Precipitation and 2) Freezing Temperatures and Low Wind Chills tonight.
** 1) WINTRY PRECIPITATION **
A *Winter Weather Advisory* is in effect for all areas through this evening, then continues until midnight for areas along and south of I-10.
As of 7 AM this morning, we’re already seeing a changeover from light rain to a mix of light freezing rain, ice pellets, and snow across the far northern extent of our forecast area from Jasper, TX through Leesville, LA to Alexandria. The mix of wintry precipitation will spread south through early afternoon, while areas north of I-10 will see a changeover to mainly snow. Accumulations are not expected to be significant, but snow amounts of one half to one inch will be possible across interior southeast Texas into central Louisiana. Farther south, snow amounts are expected to be less than one half inch. Ice accumulation is also expected to be minimal, not exceeding more than a few hundredths of an inch. Primary impacts for ice will be to bridges and elevated roadways. Precipitation will end from north to south this evening.
** 2) HARD FREEZE TONIGHT **
Temperatures will be steadily dropping through today as cold arctic air rushes in behind the front. A *Hard Freeze Warning* is in effect tonight through Wednesday morning as temperatures dip into the mid-10s to low-20s overnight. Strong northerly winds will cause wind chill values to fall into the single digits across central and western Louisiana, with lower teens elsewhere. A *Wind Chill Advisory* is in effect tonight through Wednesday morning.
* TIMING…Winter precipitation from late tonight into Tuesday.
Dangerous wind chills from Tuesday evening into Wednesday
* WIND CHILL VALUES…single digits to lower teens.
* MAIN IMPACT…Elevated roadways and bridges may become slick from ice. Light accumulations of snow on grassy surfaces and rooftops. Low wind chills may result in frostbite in as little as 30 minutes to exposed skin.
