NORTHEAST LOUISIANA, AND CENTRAL MISSISSIPPI
NATIONAL WEATHER SERVICE JACKSON MS
327 AM CDT THU SEP 17 2026
DISCUSSION
HIGH PRESSURE WILL REMAIN DOMINANT AND LEAD TO CONTINUED ABOVE
NORMAL TEMPERATURES AND MOSTLY DRY CONDITIONS LATE THIS WEEK. NEXT
BEST CHANCE OF RAIN (LOW CHANCE OF 15-30 PERCENT) LOOKS TO BE
LATE WEEKEND IN SOUTHEAST FIRE DISTRICTS WITH INCREASING COVERAGE
NEXT WEEK (LOW TO MEDIUM CHANCE 15 TO 35 PERCENT AT ALL FIRE
DISTRICTS). AFTERNOON MINIMUM RELATIVE HUMIDITY (RH) WILL DROP
NEAR CRITICAL THRESHOLDS, ESPECIALLY IN NORTHWEST FIRE DISTRICTS,
BUT LIGHT WIND WILL LIMIT FIRE DANGER. WHILE PATCHY FOG IN
SHELTERED LOCATIONS CANNOT BE RULED OUT, WIDESPREAD FOG AND
ESPECIALLY DENSE FOG ARE UNLIKELY IN THIS HOT REGIME.
