KEY MESSAGES

Issued at 1249 PM CDT Mon Apr 27 2026

- Slight Risk for severe thunderstorms now from Tyler to near Monroe in the SPC Day One through the overnight hours.

- An Enhanced Risk for more severe storms in our Four-State area Tuesday as the cold frontal forcing arrives overnight. - The cut-off low offshore of California now will be racing eastward, lifting some of the best rain totals over our freshly arrived air mass, that will bring more widespread heavy rains.

DISCUSSION

Issued at 1249 PM CDT Mon Apr 27 2026

Mostly cloudy and not much sun yet, but more perhaps in the next few hours of peak heating. Currently, low to mid 80s abound in the gusty SW wind. Our dew points are loaded for bear in the lower to a few mid 70s, while our sounding remains very capped with the clouds in place. There is a short wave phasing over the plains under the closed low over the arrow head of MN. It's subtle, but the SW flow is deep and this phasing will boost forcing aloft with a speed max pouring into the traveling short wave base for the remainder of today. The SPC has updated their day one with a deeper dip of the Slight Risk contour over more of our area, now well south of I-20 from Tyler to Gary City and Longstreet, to Hall Summit and Ruston. Monroe remains in the Marginal Risk.

Once the cap breaks, there is loads of dry air aloft above the inversion at 5.6kft. So while the rain is welcomed, the threat for large to very large hail and some wind are quite valid considering the timing using all the heating we can muster and potentially be sustained overnight with increased warmth and moisture off the Gulf of America as the dry line resets back west. So lots to watch out for this evening as "tail end Charlie" energy swings ENE down much of our I-20. And then perhaps even more so on Tuesday with the added frontal forcing areawide, thus making for another big nocturnal push scenario. The WPC also has Tuesday being potentially much wetter, upping their Marginal Risk for excessive amounts tonight, to a Slight Risk for all of our I-20 corridor on the day 2 ERO.

Our surface winds will finally shift to N early on Wednesday and usher in cooler and much more stable air bringing an end to any further threats for a respite. Mid to late week will see our muggy 80s become comfy 70s, and then the clouds and more so the cold front, that will drop down a nice chill behind the cut-off swinging through the pattern on Friday with 60s for highs this weekend. The week ending rainfall will see more elevation in the storm base and less rooted in the muggy near surface air, which will all arise with this final run of storms. Both with with less severity and more beneficial widespread (winter-like overrunning) rainfall for the new month to totals. /24/

AVIATION

(18Z TAFS) Issued at 1249 PM CDT Mon Apr 27 2026

For the 27/18Z TAF period...

High based MVFR cigs continue to hang tough across portions of Srn AR/N LA and adjacent sections of E TX, but should become VFR by mid- afternoon, and persist through at least mid to late evening before additional MVFR cigs develop over portions of E TX/Wrn LA/SW AR and quickly spread NNE across the remainder of the region overnight. However, isolated to scattered convection may develop by late afternoon/early evening over portions of NE TX/SE OK (with isolated convection development possible farther E across ECntrl LA by mid/late afternoon), which may spread E generally along and N of the I-20 corridor through the evening/overnight hours. For now, have added VCTS mention for all but the TYR/LFK terminals, with the expectation that the convection will diminish late. Depending on timing and longevity of the convection, this could delay the onset or development of the MVFR cigs, with much of the region expected to become impacted by 12Z Tuesday, persisting through much of the morning before lifting. Additional convection may develop and spread E through the region Tuesday afternoon, just beyond the end of this TAF period. SSW winds 10-15kts with gusts to 25kts this afternoon will diminish to 5-10kts after 00Z. /15/
