SHORT TERM
(Today through Wednesday)
Issued at 320 AM CDT Tue Apr 16 2024

Upper ridging extended from the Gulf of Mexico to Wisconsin this morning, with an upper low near the Colorado-Kansas border. At the surface, high pressure extended from northeast of Bermuda to the eastern Gulf of Mexico. Low pressure was noted over Nebraska with a frontal boundary eastward to the Virginia-North Carolina border.
Locally, skies were mostly cloudy. Radar indicated the possibility of a few sprinkles of rain, but they shouldn't amount to much.
Temperatures at 3 AM CDT ranged from the mid 60s to lower 70s with southeast to south winds.

The upper low will continue to move northeast over the next 36 hours as it gradually gets absorbed by a stronger system over the Canadian Prairie Provinces. The surface low will also move northeast and be centered near Green Bay Wednesday evening. This will keep the main frontal boundary well to the north through Wednesday. Can't totally rule out a few sprinkles, but the layer between 700 and 850 mb is pretty dry. Mid level RH values are generally in the 15-25% range today and 35-40% tomorrow. Forecast soundings do indicate a pretty extensive cirrus deck, though, so any sunshine the next couple days is going to be a bit filtered.
In most locations, NBM deterministic temperature numbers aren't far off the GFS/ECMWF operationals, so there's not a real significant target of opportunity to make changes.

LONG TERM
(Wednesday night through Monday)
Issued at 320 AM CDT Tue Apr 16 2024

With the northern stream system suppressing the upper ridge southward over Mexico, that sets up quasi-zonal mid level flow across the northern Gulf Coast Thursday into the weekend. The northern stream system will also serve to slowly push the frontal boundary southward toward the area as weak shortwaves move through the mid level flow.

It may take until Saturday for the front to actually reach the area. There will be one shortwave that will be a little stronger, which will move across the northern Gulf Coast Saturday night or Sunday. That will be the best rain chance over the next week, with some potential for thunderstorms. Don't see any strong indications of severe weather at this time. Drier and slightly cooler weather arrives for early next week.

Until the front arrives the weather will be unseasonably warm across the local area, with highs for at least Thursday and Friday well into the 80s across most of the area. On Friday, if we were to get full sunshine, soundings are supportive of highs around 90 away from marine influences. That would be right around record territory at our main climate sites. Highs greater than 90 degrees are a rare event in April, even in southeast Louisiana. As noted yesterday, Baton Rouge has only exceeded 90 degrees in April 3 times in the last 25 years. However, can't ignore that NBM probabilities of the high being at or above 90 degrees on Friday exceed 40 percent for a good chunk of the area near and north of a Bogalusa-Hammond-Bayou Sorrel line. Saturday will likely be the transition day, with highs Sunday and Monday mainly in the 70s.

AVIATION
(06Z TAFS)
Issued at 1148 PM CDT Mon Apr 15 2024

No major changes in thinking from the previous forecast package. A decent inversion layer has started to form over the past hour with IFR ceilings already in place at MCB. Continued deepening of the inversion will lead to LIFR ceilings and MVFR visibilities of around 3 miles. At ASD, HDC, MSY, NEW, and GPT, an extensive low stratus deck ranging from 500 to 800 feet is expected to develop beneath the elevated inversion layer during the same general time frame as MCB. Stronger winds at BTR and HUM will keep ceilings higher and in MVFR range at around 1500 to 2000 feet between 10z and 14z. After 14z, warming temperature will mix out the inversion layer, and a return to prevailing VFR conditions is expected.
Southerly winds will also turn more gusty by the end of the forecast period with sustained winds near 15 knots possible.
After 00z, another inversion will start to form and have MVFR ceilings returning by 03z at several of the terminals.

MARINE
Issued at 320 AM CDT Tue Apr 16 2024

Wind speeds have been relaxing overnight, and will allow the Small Craft Exercise Caution headlines to expire. There may be brief periods late this afternoon or evening where winds could exceed 15 knots slightly, but doesn't appear to be widespread enough to justify a prolonged period of Exercise Caution headlines. If the waters get into Small Craft Advisory criteria, it probably won't occur until Sunday night or Monday.
