1/17 – The Chief’s “Spring-Like Conditions in January” Tuesday Morning Forecast

A low pressure system over Wisconsin is dragging a cold front north of the !-20 corridor. Isolated rain south of the boundary exists all the way down to Hattiesburg. High pressure along the GOM will build northward a bit during the day. Some sunshine possible during the afternoon with most areas getting into the mid and upper 70s. Can’t rule out a few spots hitting 80 if they get enough sun.

Overnight question will be the potential for fog, with most guidance focusing on areas east of Interstate 55, and primarily north of the Interstate 10/12 corridors. Primarily an advection fog scenario, but will be wind-dependent. If winds are too strong, it’ll be just a low stratus event. While the main concern appears to be marine fog, there’s at least a low end threat that Mississippi coastal areas could be impacted.

Early portion of the long term period will have the main concern for thunderstorms during the overnight hours Wednesday night. The most likely scenario would be a broken line of convection during the overnight hours, beginning at mid-evening in the west and exiting eastern areas around 3 AM. Any severe weather threat should be brief for any one location with damaging wind the main threat, although a brief spin up can’t be ruled out entirely.

Pacific airmass behind the front on Thursday should make for a drier and fairly nice day, as cooler air doesn’t really get driven southward until Thursday night into Friday. Another disturbance will move out of the Rockies over the weekend with the potential for more widespread rainfall.
