NATIONAL WEATHER SERVICE MIDLAND/ODESSA TX
240 PM CDT MON AUG 17 2026
DISCUSSION
THE FORECAST REMAINS UNCHANGED. MIN RHS GENERALLY REMAIN ABOVE
15% AND WINDS STAY BELOW CRITICAL THRESHOLDS THROUGH THE PERIOD.
ERCS REMAIN NEAR OR JUST ABOVE THE 50TH PERCENTILE, BUT FUELS
CONTINUE TO CURE GIVEN PERSISTENT HOT AND DRY CONDITIONS.
ISOLATED TO SCATTERED STORMS ARE EXPECTED ACROSS THE HIGHER
TERRAIN AND FAR WEST TEXAS THIS AFTERNOON. STORMS THAT DEVELOP MAY
PRODUCE GUSTY/ERRATIC WINDS AND LEAD TO LIGHTNING STARTS.
HOWEVER, THE OVERALL THREAT FOR FIRE SPREAD WILL BE LOW. MOSTLY
DRY CONDITIONS PREVAIL LATE THIS WEEK INTO THIS WEEKEND.
FOR POINT-SPECIFIC FORECASTS PLEASE SEE THE POINT FIRE WEATHER
MATRIX PRODUCT ISSUED BY THE MIDLAND/ODESSA NATIONAL WEATHER
