DISCUSSION

Issued at 138 PM CDT Mon May 25 2026

Not much convection noted today as we have a relative lull in moisture across the area with a (very) weak mid-level ridge trying to build as a cutoff low drifts north and gets absorbed into an advancing trough. Moisture will begin to increase during the day tomorrow and could be enough for a few sea breeze showers/storms in the afternoon. The main event comes in tomorrow night and Wednesday morning as the aforementioned trough swings energy across the region. Expected setup is for convection to develop northwest of the area Wednesday afternoon, moving southeastward through the evening and night developing into an MCS as we often see here. We are under a marginal to slight risk for severe storms through early Wednesday morning as this moves through. Slight risk is confined to the Rio Grande Plains at this time. Will be interesting to see if the pattern of an enhancement in winds occurs as it approaches the coast occurs again as it has been in recent events. There does appear to be plenty of CAPE to work with close to the coast, so would not be surprised to see this happen again. For Wednesday, thinking it's mostly an early morning situation assuming this MCS moves through as expected. Without a low level feature as forcing, is less likely that we would see any redevelopment in the afternoon. Rainfall totals in the 1-3 inch range are expected with localized higher amounts possible. This could lead to some minor flash flood concerns, primarily due to high rainfall rates.

Temperatures remain mainly in the 80s to around 90 through Wednesday before deep layer moisture decreases a bit and 850 winds shift around to the south bringing warmer air back into the region. Temperatures will be back to near or above normal levels by late in the week.

AVIATION

(18Z TAFS) Issued at 138 PM CDT Mon May 25 2026

Expect mainly VFR conditions through this afternoon with convection remaining generally over the Gulf. MVFR CIGS likely to develop again tonight with VIS restrictions over the corridor from ALI to VCT.

MARINE

Issued at 138 PM CDT Mon May 25 2026

Light to gentle winds will continue to shift east and then southeasterly by later tonight. Flow will remain generally weak to gentle through Tuesday before increasing to gentle to fresh levels by Tuesday evening. This flow will then continue through the end of the week. A round of showers and storms is expected early Wednesday where gusty winds will be possible.
