8/15 – The Chief’s “Cold Front To The North” Tuesday Morning Forecast

A strong upper disturbance is near Chicago early this morning, extending southwest to near Oklahoma City. At the surface, a cool (NOT COLD) front extended from near Birmingham to Jackson. An EXCESSIVE HEAT WARNING will be in effect from 11 am to 7 pm today.

The area of low pressure will lift into New England by tomorrow evening; however the front is going to take a while to move out of the area. It will not be entirely east of the area until Thursday morning. In the meantime, the wind shift moves through most of the area during the day today, the elevated moisture content will drop off to about seasonal and stay north of the Interstate 10 corridor until near or after midnight tonight.

Temperatures will be in the upper 90s this afternoon, so any thunderstorms that develop will not get going until mid to late afternoon. Scattered coverage looks to be about the best we can hope for, and a good portion of the area could miss out entirely. Beyond the evening hours, any remaining thunderstorm activity is likely to be limited to the outer coastal areas. Tomorrow will be so much nicer with cooler temperatures and less humidity. This means temperatures will feel like the low to mid 90s.

Don’t get used to the more comfortable weather…it isn’t going to last long. As the area of low pressure pulls away from the area late Wednesday night and Thursday high pressure will become dominate again. Once we get past Thursday morning, we’re likely to be right back into Heat Advisories and Excessive Heat Warnings through at least Saturday. As for Friday through the weekend any thunderstorm activity more than isolated to scattered development along sea-breeze boundaries probably isn’t going to occur.
