Strong Santa Ana winds and very dry conditions are producing elevated to critical fire weather conditions in southern California. Isolated strong to severe thunderstorms are possible through early Wednesday morning across parts of northeast Texas into western Tennessee. Read More >

Key Message:
- Seasonably warm
Upper level ridging passes overhead this weekend. Warm mid level
temperatures provide a capping inversion to inhibit thunderstorm
development over our area. A weak steering flow aloft will keep any
dryline and Serranias del Burro storms west of our area until just
beyond this forecast on Sunday evening. However, cannot rule out a
few showers due to heating of a seasonably moist airmass over our
area today. Southerly flow maintains seasonably warm temperatures.

(Sunday night through Friday)
Issued at 130 AM CDT Sat Apr 26 2025
A weak disturbance over northern Mexico could generate some Sunday
evening convection over Val Verde county as it loses steam while
moving off the higher terrain and into an upper ridge over TX. Warm
and humid conditions continue Monday with another few claps of
thunder possible over Val Verde County Monday night.
Tuesday`s H5 pattern over TX shows a slightly suppressed ridge over
East TX, with the 00Z GFS showing deeper moisutre while the mid level
dry air looks less capable of keeping the cap strong. Thus some
garden variety storms are possible Tuesday afternoon and carrying
over into Wednesday. Late Wednesday, a good amount of vorticity
swoops into West Central TX which could upscale the storms into a
strong to severe line which will pull the convective focus east
Wednesday night. A cold front arrives Thursday, but it is relatively
weak under a zonal pattern aloft, and it will potentially allow for
some overrunning showers and storms for Friday into next Saturday.
