Major Arctic Air-mass Poised for the Lower 48 Next Week
An Extended Period of Subfreezing Weather Possible Over the Deep South
Hard Freeze Potential Increasing Over the Immediate Gulf Coast From South Texas to Florida Panhandle
Powerful Nor'easter Also Possible Next Week
Discussion:
We continue to gain confidence that a large Arctic Airmass will develop over western Canada this weekend and spill quickly southward over much of the Lower 48 next week bringing below to much below normal temperatures. The leading edge of the Arctic air is forecast to make quick progress southward across the Northern Rockies, Central and Northern Plains and Upper Mississippi River Valley on Sunday, January 9th, then southward across the Southern Plains, northwestern Gulf Coast and the remainder of the Mississippi Valley on Monday, January 10th. The cold air will then slide eastward across the Atlantic Seaboard and Deep South on Tuesday, January 11th as low pressure quickly intensifies off the North Carolina Coast.
Temperature Concerns:
Temperatures will likely drop well below normal behind the Arctic Airmass through the remainder of next week over most areas east of the Rockies, especially over the Great Plains and Mississippi Valley from the Dakotas and Minnesota southward to Texas and Louisiana. Be advised there is now an increasing risk for a hard freeze along the immediate Gulf Coast from south Texas through Mobile Bay as the Arctic Airmass builds over the region. Even though it’s a little too early to predict overnight lows this far out, there's some potential that temperatures could fall as low as the low to mid 20s over the immediate coast from South Texas to the Florida Panhandle sometime during the time period from January 12th through 17th. Just inland from the coast from South Texas to South Georgia temperatures as low as the teens and low 20s will be possible, with the best chance occurring again from the 12th to the 17th. Lows in the single digits and teens are looking increasingly more likely from north Texas and Oklahoma, eastward across northern Mississippi and Alabama to the western Carolinas. Another huge concern over the Deep South are daytime highs may average only in the 20s and 30s from Texas and Oklahoma eastward to the Carolinas and Florida Panhandle during this same time period.
