Cullman County Urgent Winter Weather Advisory January 6 2017
* Light Snow Expected (up to 2″)
* Sleet & Freezing Rain Also Possible
* Wind Chills Friday Night (0° to 10°)
* Hazardous Driving Conditions (melted moisture re-freezing)
The National Weather Service (NWS) in Huntsville has issued an urgent Winter Weather Advisory alerting of:
‘LIGHT SNOW ACCUMULATIONS POSSIBLE FRIDAY MORNING INTO FRIDAY NIGHT’
The NWS believes a band of light snow will push east across the northwest portions of northern Alabama this morning.
They indicate that snow accumulations up to 1 INCH are possible through 12 noon.
NWS expects the second band of snow to move across northern Alabama during the later afternoon to early evening hours with snowfall likely to end west of Interstate 65 by midnight.
An additional 1/2 INCH of snow is possible with this 2nd band with snow lingering east of I-65 until 3 am with accumulations of up to 2 INCHES in the western area, especially in higher terrains.
Temperatures will fall into the teens late Friday night with any moisture that melts re-freezing quickly potentially causing roadway icing and the chance of hazardous road conditions.
North winds up to 20 mph Friday night into early Saturday morning will yield WIND CHILL values of 0° to 10° in northern Alabama.
The NWS in Birmingham sent up one of their sophisticated weather balloons earlier this morning. It found HUGE amounts of warm air aloft. They expect all liquid precipitation with SLEET & FREEZING RAIN to be the main threat this morning. (See comments section for their balloon findings).
“If you have to travel, GET IT DONE NOW! Deteriorating conditions expected this afternoon.”
NOTE: Regular operations at Birmingham-Shuttlesworth & Huntsville International Airport may be impacted this afternoon and evenings. Anticipating delays and cancellations at Atlanta’s Hartsfield Airport tomorrow seems wise.
