New AVIATION

SHORT TERM
(This evening through Wednesday night)
Issued at 145 PM CDT Tue Apr 23 2024

Under sunny skies and a zonal/progressive upper flow regime, temperatures have warmed across the region. With the surface flow veering to a more onshore flow with the surface high departing stage east, some better low level moisture has started to creep northward back into the area. This will limit critical fire weather concerns this afternoon.

Overnight, the upper level flow will transition to a dry northwesterly flow and a surface front will make an attempt to near the region. Although low level moisture influx has been weak, there is still a weak SREF signal for lower visibilities, especially across southwest Mississippi, where some shallow fog isn't out of the realm of possibility, especially if some moisture pool develops ahead of a stalling front just upstream over central MS/AL.

On Wednesday, outside of some scattered high clouds, the story will be temperatures (and that isn't even much of a story). With a continuation of increasing heights, temperatures should continue to increase gradually...both MaxT's and MinT's. (Frye)

LONG TERM
(Thursday through Monday night)
Issued at 145 PM CDT Tue Apr 23 2024

The long term period starts with the stalled front just to our north and east. Again, ahead of the front there could be some morning fog, however, as pressure gradient tightens between a high to our east and a strengthening surface low over the high plains, this will become less of a concern late in the week. The northwesterly flow on the eastern periphery of a ridge axis over Texas will eventually transition to a southwesterly flow by Friday as a strong H5 trough begins to amplify over the central plains.
This trough will suppress the upper ridge across the Gulf of Mexico...as such the heights and thicknesses will increase across our region allowing for the warming trend to continue before balancing out later in the weekend or early next week.

A cold front stalls upstream early in the weekend close to the Sabine River and ArkLaTex region. This will likely keep most rain chances up that way this weekend. A strong mid and upper level impulse amplifies and takes the same path roughly as the prior weaker impulse. This feature looks to move the aforementioned stalled frontal boundary eastward toward our area early next week.
As it does, we'll likely start seeing an uptick and scattered showers and thunderstorms, especially across our western tier counties/parishes late Monday or early Tuesday. Still low confidence in timing and precip probs, but we'll fine tune going into the weekend. (Frye)

AVIATION
(00Z TAFS)
Issued at 632 PM CDT Tue Apr 23 2024

VFR conditions across all terminals at issuance time this evening.
That should remain the case through the forecast period at most terminals, with the exception being KMCB, where radiation fog formation could produce MVFR to IFR visibilities for a couple hours around sunrise. With moisture levels slowly increasing, could see some cumulus clouds develop by late morning or early afternoon Wednesday. However, cloud bases are likely to remain above FL030.

MARINE
Issued at 145 PM CDT Tue Apr 23 2024

Fairly benign marine conditions early on in the forecast period.
Onshore flow is anticipated to develop and gradually strengthen through the week. During the afternoons, winds could be enhanced over the MS Sound and Tidal Lakes. May need short fused Cautionary headlines or even SCA if the forecast trends up even just slightly. The pressure gradient increases on Friday and through the weekend where Cautionary headlines and/or SCAs look to be a safe bet across the local waters. (Frye)
