DAY 1 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0640 AM CST SAT DEC 13 2025
VALID 131300Z - 141200Z
..NO SEVERE THUNDERSTORM AREAS FORECAST
..SUMMARY
SEVERE THUNDERSTORMS ARE NOT EXPECTED TODAY OR TONIGHT.
..DISCUSSION
LARGE-SCALE TROUGH AMPLIFICATION WILL OCCUR OVER THE MIDWEST/EAST
THROUGH TONIGHT, WITH EXPANDING SURFACE HIGH PRESSURE ACROSS THE
PLAINS AND MIDWEST IN THE WAKE OF A COLD FRONT PROGRESSING
SOUTH-SOUTHEASTWARD TOWARD THE LOWER MISSISSIPPI VALLEY AND GULF
COAST BY LATE TONIGHT AND EARLY SUNDAY. PRECEDING THE FRONT, WEAK
WARM/MOIST ADVECTION SHOULD ALLOW FOR NORTHEASTWARD-EXPANDING
THUNDERSTORM DEVELOPMENT ACROSS SOUTHEAST TEXAS AND LOUISIANA TODAY,
WITH POTENTIAL PERSISTING UNTIL THE FRONTAL PASSAGE TONIGHT.
A LOW-LATITUDE DISTURBANCE CROSSING THE GULF AND A NORTHWARD
MOISTURE FLUX AHEAD OF IT WILL CONTRIBUTE TO THUNDERSTORM POTENTIAL
ACROSS THE FLORIDA KEYS/FLORIDA STRAITS TODAY, AND ALSO ACROSS THE
SOUTHERN FLORIDA PENINSULA TONIGHT. SEVERE THUNDERSTORMS ARE
UNLIKELY WITH THESE SCENARIOS.
