DISCUSSION
ISSUED AT 328 AM CDT SUN OCT 18 2026
THE UPPER LEVEL TROUGH WHICH HELPED USHER IN COOLER TEMPERATURES
EARLIER WILL CONTINUE SHIFTING EAST WHILE RIDGING ALOFT BUILDS INTO
THE REGION FROM THE WEST THROUGH THE DAY. AS THIS RIDGE BUILDS IN
EXPECT LIGHTER WINDS AND TEMPERATURES A BIT WARMER THIS AFTERNOON.
CRITICALLY LOW AFTERNOON MINIMUM RELATIVE HUMIDITY VALUES THROUGH
THE WEEK WILL ALLOW FOR FIRE DANGER CONCERNS TO PERSIST FOR SEVERAL
DAYS. PLEASE CONTINUE TO MONITOR THE LATEST FORECAST AND OUTLOOK, AS
APPROPRIATE FIRE WEATHER HAZARDS/PRODUCTS MAY NEED ADJUSTMENTS TO
AREAL COVERAGE AND INTENSITY DAY TO DAY, PARTICULARLY THROUGH THE
WORK WEEK. LIGHTER WINDS THROUGHOUT THE WEEK WILL MITIGATE AGAINST A
HIGHER FIRE WEATHER THREAT.
THIS SURFACE HIGH AND INCREASED RIDGING ALOFT FROM UPSTREAM WILL
ENSURE WEATHER CONDITIONS FOR THE WEEK REMAIN CALM AND QUIET, WITH
TEMPERATURES RAISING DAILY.
FIRE WEATHER CONCERNS REMAIN THE MOST SIGNIFICANT FACTOR SO FAR THIS
WEEK. FIRES MAY RAPIDLY SPREAD ONCE STARTED DUE TO DRY FUELS./OAJ/
