SHORT TERM
(Today through Thursday night)
Issued at 219 AM CDT Tue Apr 23 2024

High pressure remains the main factor influencing our weather and will continue to be so through the middle of the week with clear skies and calm conditions. 

Cold air advection will bring temperatures well below average with highs 5 to 10 degrees below average. Highs today will still be cooler than normal, with highs only in the low to mid to upper 70s.
This will be the last day before the 80s return along with more humid conditions.Consistent warm air advection will increase on Wednesday leading to a steady increase in temperature and humidity. The increase in moisture will see an increase in fog during the early morning hours. On Thursday a front will extend across north Louisiana. This will increase our pressure gradient and winds.

LONG TERM
(Friday through Tuesday)
Issued at 219 AM CDT Tue Apr 23 2024

As the forecast period begins, the forecast area will be under a very warm and humid pattern with high pressure at the surface off the southeast US coast ridging into the forecast area providing southerly flow bringing in warm and moist Gulf of Mexico air.
Despite the moist air mass, upper level ridging will keep the atmosphere capped, along with keeping the storm track well to the north, and thus no significant shower activity is expected.

It will also become quite breezy on Friday as a deep low pressure system will form over the Plains allowing for a tight gradient over the region. Conditions will be close to advisory criteria with sustained winds nearing 20 mph and gusts close to 30 mph.

The pattern will persist into Saturday with possibly an even stronger low level jet that will allow for sustained southerly winds in the 20 to 25 mph range with gusts over 35 mph, and if this verifies, wind advisory criteria will be met.

By Sunday afternoon, the upper level ridge looks to shift a little to the east. This will allow for a short wave to cut into the ridge and move through the region late Sunday into Monday. The weakness aloft and plenty of Gulf moisture will allow for a chance of showers and thunderstorms during that time period.

AVIATION
(06Z TAFS)
Issued at 1120 PM CDT Mon Apr 22 2024

Light, variable winds are anticipated through at least sunrise with high pressure in control. Surface high will continue a movement to the east throughout the day Tuesday resulting in winds prevailing from the south-southeast and south after 15Z.
Daytime winds will increase to around 10 to 12 kts with some higher gusts in the mix from diurnal impacts. Winds decrease after 01 to 02Z, but will remain from the south.

VFR skies with only some high cirrus are expected thru much of the period. Southerly flow brings moisture and lower clouds in at BPT towards the end of the period with all terminals seeing some lowered VIS after 06Z.
