Crisp, Arctic Air Snaps Into East, Midwest

January 22, 2020
UPDATED By WeatherBug's Chris Sayles
Arctic air is sending chills through most of the East and Midwest today, reaching as far south as southern Florida. Thankfully, the cold will depart during the latter half of the workweek.

A large high-pressure system diving into the eastern half of the U.S. will keep frigid air locked in place mid-week. Parts of New England are waking up to temperatures in the frosty teens while the Mid-Atlantic, eastern Plains and the Ohio and Middle Mississippi valleys only rise into the 20s and 30s.

The Arctic air has oozed deep into the Southeast, and not even Florida can escape winter's grip this time. Residents north of the I-4 corridor will notice brisk changes with morning temperatures in the 30s, while crisp northerly winds aid even colder low to mid-20s along the Florida Panhandle.

Freeze Warnings and Wind Chill Advisories are in effect for places such as Miami, Orlando and Jacksonville, Fla., and Tifton, Ga. Wind chills will range between the mid-20s and 30s as far south as Miami and Homestead, Florida on Wednesday morning. The last time a wind chill advisory was posted this far south in Florida was in February of 2015. 

The unusually cold weather will not last long. High-pressure will shift to the east late today into Thursday, and southerly winds ahead of a developing low-pressure system will lead to a warming trend. Portions of the Midwest, Mid-Atlantic and Northeast will see normal to above normal temperatures by Thursday afternoon, with highs in the mid to upper 30s and 40s.

Along with the cold, a wintry weather disturbance will spread through the Nation's Midsection today. Heavy rain will be reserved for Texas, whereas ice, sleet and possibly snow will blanket central Plains and Upper and Middle Mississippi Valley. This goes for Kansas City, Mo., St. Louis, Omaha, Neb., Tulsa, Okla., and Fayetteville, Ark., where Winter Weather Advisories have been issued where snow totals up to 3 to 4 inches and a glaze of ice are expected.
