Arctic Blast This Weekend

An expansive storm system is going to impact the eastern 2/3 of the country this weekend.

Widespread rain and storms will be likely from Texas to the Florida Panhandle along/ahead of a trailing front Friday – Saturday. Some strong to severe storms will be possible. However, the overall threat does not look too impressive at this point.

Behind the front, a blast of bitter arctic air will push south, into the South and Gulf Coast States. Temperatures will drop well below-average. And as of now, a hard freeze is looking probable for east Texas Saturday night/Sunday morning.

A hard freeze will then be likely again Sunday night/Monday morning, including points east (LA, MS, AL and the FL Panhandle), along with wind chills in the single digits and teens.

This storm system and institution of arctic air is going to mark the start of a more sustained cold and stormy pattern, which long-range guidance indicates will last into next month. This means several more storm systems and waves of arctic air are a good bet over the next few weeks.
