SHORT TERM
(SUNDAY NIGHT THROUGH TUESDAY NIGHT)
ISSUED AT 201 AM CDT SUN JUL 26 2026
VERY HOT TEMPERATURES WILL CONTINUE INTO EARLY NEXT WEEK WITH
CONTINUED WIDESPREAD TRIPLE DIGIT TEMPERATURES. DRIER AIR WILL FILL
IN ACROSS THE WESTERN PORTIONS OF THE AREA WITH SLIGHTLY LESS HUMID
HEAT. HOWEVER, WITH TEMPERATURES BEING SO WARM, HEAT HEADLINES ARE
STILL LIKELY TO PERSIST EACH DAY. WITH THE DRIER AIR OUT WEST,
RELATIVE HUMIDITY VALUES WILL DROP INTO THE TEENS AND THANKS TO
CONTINUED HEAT AND A LACK OF SUBSTANTIAL RAIN, ELEVATED FIRE WEATHER
MAY RETURN IN THE AFTERNOON ACROSS PORTIONS OF WESTERN OKLAHOMA
MONDAY AND TUESDAY AFTERNOON. PRECIPITATION CHANCES WILL REMAIN LOW
MONDAY AND TUESDAY. NORTHWESTERLY FLOW MAY RETURN TUESDAY AND AN
EMBEDDED SHORTWAVE COULD BRING LOW CHANCES FOR CONVECTION OFF THE

NORTH OF THE RIDGE AND BEING ON THE EASTERN PERIPHERY, NORTHWESTERLY
FLOW IN COMBINATION WITH THE SHORTWAVES MAY BRING CHANCES FOR
PRECIPITATION TO PORTIONS OF NORTHERN OKLAHOMA. BY FRIDAY, THE UPPER
RIDGE WILL CONTINUE TO RETROGRADE WESTWARD INTO THE DESERT SOUTHWEST
WITH A STRONGER SHORTWAVE DIVING SOUTHWARD ACROSS THE CENTRAL PLAINS
