FIRE WEATHER PLANNING FORECAST FOR THE MIDSOUTH
NATIONAL WEATHER SERVICE MEMPHIS TN
330 PM CDT WED APR 22 2026
DISCUSSION
MINIMUM RELATIVE HUMIDITY WILL FALL TO 25-35% ACROSS MUCH OF THE
MID-SOUTH AGAIN TODAY (MORE LIKE 30-40% WEST OF THE MISSISSIPPI
RIVER) WITH SOUTHERLY 20-FT WINDS OF 8-14 MPH THROUGH SUNSET.
THIS WILL RESULT IN ANOTHER DAY OF ELEVATED FIRE WEATHER
CONCERNS. RH WILL MODERATE THURSDAY AND FRIDAY AS LOW-LEVEL
MOISTURE INCREASES AHEAD OF THE NEXT SYSTEM. A WETTING RAIN IS
LIKELY AREA WIDE FRIDAY AFTERNOON INTO THE OVERNIGHT PERIOD AS
SHOWERS AND THUNDERSTORMS TRAVERSE THE REGION.
THERE REMAINS A LOW CHANCE (20-40%) FOR SHOWERS AND THUNDERSTORMS
SATURDAY AND SUNDAY, BUT THE NEXT SIGNIFICANT SYSTEM WILL BRING
ANOTHER ROUND OF THUNDERSTORMS ON MONDAY.
