.DISCUSSION…
IN THE SHORT-TERM… WILL WATCH FOR THE CHANCE OF THUNDERSTORM
DEVELOPMENT IN OR NEAR THE NORTH TEXAS COUNTIES. THERE HAS BEEN A
PERSISTENT SIGNAL IN THE MESOSCALE MODELS HAVE STORM DEVELOPMENT
IN THE ARCHER COUNTY AREA THIS AFTERNOON… AND CU FIELD HAS BEEN
INCREASING NW OF BRECKENRIDGE TX AND SOUTH OF COLEMAN TX. WILL
LEAVE THE ISOLATED WORDING AND SUB-20 POPS IN THE FORECAST THIS
EVENING ACROSS NORTH TEXAS AND EXTREME SOUTHWEST OKLAHOMA. LATER
TONIGHT IT APPEARS THAT AREAS OF FOG SHOULD REDEVELOP…
ESPECIALLY IN NORTHWEST AND CENTRAL OKLAHOMA.
ATTENTION THEN TURNS TO STORM CHANCES THIS WEEKEND AND INTO EARLY
NEXT WEEK. ALTHOUGH WE LOOK TO HAVE A HEALTHY CAP IN PLACE
TOMORROW… MODELS ARE CONSISTENT WITH DEVELOPING QPF ACROSS
NORTHERN OKLAHOMA AND THE ECMWF BREAKS OUT A LOT OF PRECIPITATION
AHEAD OF THE DRYLINE THROUGHOUT WESTERN OKLAHOMA AND WESTERN NORTH
TEXAS. WILL KEEP HIGHEST POPS IN THE NORTH BUT KEEP AT LEAST 20S
THROUGHOUT THE WESTERN HALF OF THE AREA. STORM CHANCES INCREASE
SUNDAY AS UPPER WAVE MOVES CLOSER. WE THEN RELOAD FOR ANOTHER
ROUND ON MONDAY AS ANOTHER WAVE DEVELOPS IN THE BROAD UPPER TROF
TO THE WEST AND MOVES TOWARD THE PLAINS AND A SURFACE FRONT MOVES
THROUGH SOME OF THE AREA. SEVERE WEATHER WILL CERTAINLY REMAIN A
POSSIBILITY ON EACH OF THESE DAYS.
