PRESSURE ADVANCES EASTWARD OFF THE HIGH PLAINS, FURTHER TIGHTENING
THE PRESSURE GRADIENT LEADING TO GUSTY SOUTHWESTERLY WINDS ACROSS
MUCH OF EASTERN OKLAHOMA. THE GUSTY WINDS AND CONTINUED LOWER

MORE DROUGHT STRICKEN AREAS. REMAIN AWARE OF ONGOING BURN BANS
ACROSS THE AREA.
A WELCOME PATTERN CHANGE WILL ARRIVE BEGINNING LATE SATURDAY NIGHT IN
THE FORM OF A COLD FRONT. SHOWERS AND THUNDERSTORMS ARE FORECAST TO
DEVELOP WEST OF THE FORECAST AREA SATURDAY EVENING AND PROGRESS
EASTWARD INTO SATURDAY NIGHT. THESE INITIAL STORMS WILL LIKELY STALL
OUT AND DISSIPATE MAINLY NORTH OF I-44 SATURDAY NIGHT INTO EARLY
SUNDAY MORNING. ANOTHER UPTICK IN SHOWERS AND STORMS WILL THEN
ACCOMPANY THE ACTUAL COLD FRONT LATER SUNDAY MORNING INTO SUNDAY
AFTERNOON. STORM COVERAGE WILL THEN SPREAD SOUTHEASTWARD WITH THE
SLOWLY ADVANCING FRONTAL BOUNDARY THROUGH EARLY MONDAY. A FEW STRONG
TO SEVERE STORMS WILL BE POSSIBLE DURING THE DAY SUNDAY, ALONG WITH
LOCALLY HEAVY RAINFALL DUE TO THE SLOW FRONTAL PROGRESSION.
RAIN CHANCES WILL LINGER IN TO MONDAY AS COOLER, MORE SEASONABLE AIR
FILTERS INTO THE REGION. CLOUDINESS AND COOLER SURFACE HIGH PRESSURE
SETTLING OVER THE AREA COULD KEEP TEMPERATURES IN THE 70S MONDAY AND
TUESDAY, ESPECIALLY NORTH OF I-40, MARKING A NOTABLE COOLDOWN
