145 PM EDT WED AUG 13 2025
DISCUSSION
LIMITED POTENTIAL FOR WIDESPREAD WETTING RAIN EXISTS, BUT STORMS
CAPABLE OF LOCALIZED HEAVY RAINFALL ARE POSSIBLE TODAY AND TONIGHT
AS A COLD FRONT CROSSES THE REGION. BROAD LIGHT RAIN IS NOT OUT OF
THE QUESTION, ESPECIALLY IN THE I-80 CORRIDOR, BUT IT WILL DO
LITTLE TO QUELL THE EXCESSIVE DRY TERRAIN. LITTLE LIKELIHOOD
EXISTS FOR DANGEROUS FIRE-WEATHER CONDITIONS.
