SHORT TERM
(This evening through Thursday night)
Issued at 329 PM CDT Wed Apr 17 2024

A weak upper level low is currently moving through the Great Lakes this afternoon. It's too far north to send a front down to the Gulf Coast. However, moisture convergence extends from that far north down into Louisiana. Radar shows that even though PW is below 1.5", still have isolated showers able to develop over the CWA Thus, have done a last minute update to the forecast to account for this and added some isolated showers to many zones. QPF should be relatively minimal. Going into tomorrow, a stronger upper level trough will push south out of Canada and into the High Plains to upper Mississippi River Valley. Down here on the Gulf Coast, atmospheric column moisture content will be slightly higher than today. 500mb forecast looks to have a barely discernible shortwave possibly passing across the Lower Mississippi Valley. CAMs seem to pick up on this much better than the global models and depict scattered showers possible across the CWA Therefore, have added them to the afternoon forecast. Otherwise, another warm day expected with temps well above normal with highs in the upper 80s.

LONG TERM
(Friday through Tuesday night)
Issued at 329 PM CDT Wed Apr 17 2024

The above mentioned upper trough will continue east across the Great Lakes Friday and Saturday. The upper low aloft will still be fairly flat/zonal with possibly weak ridging in place. That'll still promote slightly more moderating temps. Could see an isolated location or 2 reach 90 degrees on Friday. That'll be within the realm of record highs for the local area.

As we go through the weekend, models show a shortwave on the backside of the northern trough moving through the region. This is what'll be needed to drive a cold front through the CWA on Sunday.
Ample moisture in place with lift from the front will be a good setup for increasing showers and thunderstorms. Latest forecast depicts this with rain chances increasing to near 80% and rainfall totals around an inch. This cold front won't be particularly strong, so only looking at a day of below normal temps with moderating conditions quickly returning as well as above normal temps Tuesday onward.

AVIATION
(18Z TAFS)
Issued at 329 PM CDT Wed Apr 17 2024

Surface obs and visible satellite quickly point out cloud impacts at terminals with MVFR conditions dominating the forecast at pretty much all terminals. As the late afternoon through overnight period progresses, should see cloud decks lower back into IFR heights.
Could see LIFR Thursday morning as well as areas of light fog impact TAF sights. Those lower visibility conditions should improve by mid morning.

MEFFER

MARINE
Issued at 329 PM CDT Wed Apr 17 2024

A surface high pressure centered east of the local coastal waters will remain generally in that position through the rest of this week and starting this weekend. That'll keep onshore flow in place, but weaker pressure gradient should limit wind speeds and sea/wave heights. Current global model runs indicate that a cold front will move through the coast waters Sunday afternoon. Cold air advection won't be particularly strong with this boundary and thus likely only looking at about 12 to 18 hours of Exercise Caution conditions.
