DISCUSSION
ISSUED AT 134 AM CST WED FEB 18 2026
THE H500 PATTERN WILL REMAIN ZONAL TO SOUTHWESTERLY THE NEXT
COUPLE OF DAYS AS ELONGATED RIDGING PERSISTS FROM THE EASTERN
PACIFIC ACROSS THE GULF. A SERIES OF MID-LEVEL SHORTWAVE TROUGHS
WILL LIFT FROM THE SW US TOWARD THE GREAT LAKES OVER THE NEXT FEW
DAYS.
FOR THURSDAY, ONE OF THE H500 TROUGHS WILL MOVE JUST NORTH OF THE
STATE WITH A CORRESPONDING SFC LOW AND TRAILING COLD FRONT
APPROACHING FROM THE WEST. STRONG SFC WINDS DUE TO THE ENHANCED
PRESSURE GRADIENT AHEAD OF THE FRONT WILL BE SEEN ACROSS MUCH OF
THE STATE. VERY DRY AIR WILL ALSO BE IN PLACE, ESPECIALLY ACROSS
PORTIONS OF W/N ARKANSAS. AS TEMPERATURES CLIMB TO NEAR RECORD
LEVELS THU AFTERNOON, MIN RH VALUES ARE LIKELY TO DIP DOWN BELOW
20 PERCENT. THIS COMBINATION WILL LEAD TO INCREASED WILDFIRE
DANGER AND POTENTIAL RED FLAG CONDITIONS THURSDAY AFTERNOON.
THE FRONT WILL PROGRESS THROUGH BY FRIDAY MORNING WHICH WILL BRING
COOLER TEMPERATURES TO THE AREA. THE H500 RIDGE TO THE SOUTH WILL
BEGIN TO CONTRACT AND DRIFT FARTHER SW WHICH WILL ALLOW A WEAK
SYSTEM TO MOVE THROUGH FROM FRIDAY INTO SATURDAY. COMPARED TO
YESTERDAY, MUCH LESS PRECIP COVERAGE AND QPF IS EXPECTED. BUT, THE
FLOW ALOFT WILL TURN MORE OUT OF THE NW AND SFC RIDGING WILL
EXPAND SOUTH INTO THE REGION. THIS WILL ALLOW MUCH COOLER
TEMPERATURES THROUGH EARLY NEXT WEEK.
