Day 1 Convective Outlook
NWS Storm Prediction Center Norman OK
0804 PM CDT Sat Apr 19 2025
Valid 200100Z - 201200Z
...THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS CENTRAL TEXAS
INTO SOUTHEAST OKLAHOMA...
...SUMMARY...
A couple of strong tornadoes will be possible this evening into
tonight across north-central Texas and southeast Oklahoma.
Elsewhere, very large hail will be possible late tonight across west
Texas as additional thunderstorms develop.
... 01Z Update ...
The major change to this update is to introduce an enhanced risk
(Level 3 of 5) for tornadoes across north-central Texas into
southeast Oklahoma. Here, surface dewpoints into the mid 60sF along,
southeast surface winds, and an increasing low-level jet will yield
an increasingly favorable environment for a couple of strong
tornadoes through the evening and into the overnight hours. The
observed 00Z RAOB from Dallas/Fort Worth is indicative of this kind
of environment with MLCAPE around 1500 J/kg and 0-3km SRH of 380
m2/s2.
Additional thunderstorms capable of producing very large hail and
damaging wind threat should redevelop/continue into tonight across
portions of west Texas as the main upper-level low begins to eject
into the Plains.
