NEAR TERM
(TODAY AND TONIGHT)
ISSUED AT 1213 AM CDT WED APR 30 2025
SIGNIFICANT FLASH FLOODING AND SEVERE THUNDERSTORMS (ALL HAZARDS)
CONTINUE TO BE THE HEADLINES IN THE SHORT TERM.
AS ONE ROUND OF SHOWERS AND STORMS MOVES OUT, WE CAN SEE THE NEXT
ROUND DEVELOPING IN NORTH AND WEST TEXAS. IN GENERAL, CAMS SEEM TO
BE RUNNING ON THE SLOW SIDE. WHILE CAMS SUGGEST A BREAK IN STORMS,
RADAR TRENDS SUGGEST THERE MAY NOT BE MUCH OF A BREAK. THUS FAR, 24-
HR RAINFALL AMOUNTS HAVE BEEN 1 TO 2.5 INCHES ALONG THE I-44
CORRIDOR WITH LOCALLY HIGHER AMOUNTS. ANOTHER 1 TO 3 INCHES IS
EXPECTED OVER THE NEXT 12-18 HOURS, MAINLY OVER SOUTHERN OKLAHOMA
AND NORTH TEXAS. THIS IS ON TOP OF AN AREA THAT ALREADY HAS NUMEROUS
FLASH FLOOD WARNINGS.
AS MENTIONED IN THE PREVIOUS AFD, ALL OTHER CONVECTIVE HAZARDS
REMAIN POSSIBLE-ESPECIALLY SOUTH OF THE BOUNDARY. THOSE HAZARDS WILL
BE DICTATED BY CONVECTIVE MODE...WITH THE BEST CHANCE OF
DISCRETE/SUPERCELL STORMS OVER THE RED RIVER VALLEY AND POINTS
SOUTH. OTHERWISE, CONVECTIVE SEGMENTS/CLUSTERS ALSO HAVE READILY
PRODUCED DAMAGING WIND GUSTS WITHIN THIS AIRMASS.
CAMS DEPICT THE LAST ROUND WEDNESDAY AFTERNOON / EVENING. THIS ROUND
APPEARS TO BE MORE PROGRESSIVE AND MUCH SMALLER IN AREAL EXTENT,
THOUGH CONFIDENCE IN CAM PREDICTIONS OUT THIS FAR IS LOW DUE TO
EFFECTS FROM CONVECTION BETWEEN NOW AND THEN.
