FIRE WEATHER PLANNING FORECAST FOR SOUTHWEST ARKANSAS...

AND EXTREME SOUTHEAST OKLAHOMA
NATIONAL WEATHER SERVICE SHREVEPORT LA
227 AM CDT SUN SEP 20 2026
DISCUSSION
ALTHOUGH SOME WEATHER CHANGES ARE ON THE WAY IN THE FORM OF A COLD
FRONT, THE INTENSE HEAT WILL CONTINUE TODAY WITH MID TO UPPER 90S
AND SOME ISOLATED TRIPLE DIGIT HIGH TEMPERATURES. DRIER AIR IN
PLACE WILL RESULT IN MIN RH VALUES RANGING BETWEEN 25-35 PERCENT
WITH SOUTHERLY WINDS GENERALLY REMAINING BELOW 10 MPH. HOWEVER,
THE DRY AIR IN PLACE MAY CONTRIBUTE TO SOME SLIGHTLY HIGHER GUSTS
MIXING DOWN TO THE SURFACE DURING THE AFTERNOON HOURS LATER TODAY.
THEREFORE, FIRE DANGER CONCERNS WILL REMAIN ELEVATED UNDER THESE
CONDITIONS GIVEN HOW DRY FUELS HAVE BECOME OVER THE PAST SEVERAL
WEEKS. BY TONIGHT INTO MONDAY, THE AFOREMENTIONED COLD FRONT WILL
ADVANCE INTO THE REGION AND BRING SLIGHTLY MILDER TEMPERATURES AND
EVENTUALLY A NORTHERLY WIND SHIFT. UNFORTUNATELY, LITTLE IF ANY
RAINFALL LOOKS TO COME OUR WAY WITH THIS FRONT.
