As a chill reaches deep into the South during the middle of the week, the first freeze of the season will arrive for Dallas, Birmingham, Ala., and Atlanta.
The core of the Arctic air is forecast to take aim on the Midwest and Northeast. However, it will send temperatures to or below freezing for a number of hours from northern and western Texas to the northern and central parts of Louisiana, Mississippi, Alabama, Georgia and South Carolina, as well as central and western North Carolina and part of the Virginia Tidewater.
The date of the freezing temperatures will arrive close to or a little ahead of the 30-year average.
Freezing temperatures will stop short of the Gulf and southern Atlantic coasts. But, the coolest air of the season so far is in store for these areas including South Texas, the Florida Peninsula and the Keys.
On Wednesday temperatures will be held to the 50s in New Orleans, Houston, and Jacksonville, Fla., and the 60s in Orlando and Brownsville, Texas. Temperatures may struggle to reach 50 degrees Wednesday at Myrtle Beach, S.C. The high is forecast to be in the 40s around Charlotte, N.C.
Around much of the Gulf and the southern Atlantic coast, the chill will be accompanied by a stiff breeze for all or part of the time, resulting in even lower RealFeel® temperatures.
For most of the region, the cool air will not be accompanied by precipitation. However, this will not be the case for everyone.
In parts of West Texas, northeastern New Mexico, the Oklahoma Panhandle and southeastern Colorado, the arrival of the cold air can be accompanied by a bit of freezing rain and slippery travel late Monday night into Tuesday.
A few snowflakes are forecast for parts of the southern Appalachians and Piedmont Tuesday evening. However, any small accumulation would be limited to the higher elevations.
Rain showers will affect parts of South Texas, the Keys and the east coast of Florida Wednesday.
