UPPER LEVEL RIDGING EXPANDS INTO THE REGION MONDAY, PROMOTING

THE RIDGE WILL STRENGTHEN FURTHER ON TUESDAY AND WEDNESDAY WITH
HIGH TEMPERATURES RESPONDING AND INCREASING INTO THE UPPER 90S AND
LOWER 100S. DEWPOINTS WILL ALSO INCREASE DURING THIS TIME AND
RISING HEAT INDICES MAY WARRANT HEAT HEADLINES FOR PORTIONS OF
THE AREA. THE TULSA METRO AREA AND AR RIVER VALLEY ARE MOST AT
RISK FOR HIS GREATER THAN 105 DEGREES TUESDAY AND WEDNESDAY. DRY
CONDITIONS ARE LIKELY TUESDAY AND WEDNESDAY, THOUGH A FEW ISOLATED
SHOWERS CANNOT BE RULED OUT WEDNESDAY AFTERNOON ACROSS THE HIGHER
TERRAIN OF SE OK AND W AR AS DEEPER MOISTURE IS PULLED NORTHWARD.
MEANWHILE, NORTH OF THE RIDGE, BROAD TROUGHING WILL DEVELOP
ACROSS THE NORTHERN PLAINS THROUGH MID WEEK. AS A SERIES OF
IMPULSES ROUND THE BASE OF THE TROUGH, A WEAK COLD FRONT WILL BE
PUSHED INTO THE CENTRAL PLAINS AND THEN INTO NORTHERN PORTIONS OF
OUR AREA LATE WEDNESDAY.
THE FRONT WILL TEND TO INCREASE PRECIPITATION POTENTIAL ACROSS NE
OK AND NW AR THROUGH LATE WEEK, ESPECIALLY WHILE RIDGING IS
SUPPRESSED AS ANOTHER SHORTWAVE OR TWO INFLUENCE THE REGION
THURSDAY INTO FRIDAY. WHILE MODEL SOLUTIONS VARY AT THIS RANGE,
HIGHEST RAIN/STORM POTENTIAL IS CURRENTLY EXPECTED TO REMAIN ALONG

THREAT FOR LOCALLY HEAVY RAINFALL AND STRONG WIND GUSTS. HEIGHTS
INCREASE SOMEWHAT AGAIN THIS WEEKEND INTO EARLY NEXT WEEK, THOUGH
LOW DIURNAL RAIN/STORM CHANCES MAY PERSIST WITH DEEPER MOISTURE IN
PLACE. TEMPERATURES AND ASSOCIATED HEAT RISK THROUGH THE END OF
THE FORECAST PERIOD WILL DEPEND ON PLACEMENT OF THE FRONTAL
BOUNDARY AND PRECIPITATION COVERAGE, BUT POTENTIAL FOR DANGEROUS
HEAT WILL LIKELY PERSIST INTO THIS WEEKEND. LONG RANGE GUIDANCE
CONTINUES TO SUGGEST ABOVE AVERAGE TEMPERATURES AND NEAR TO BELOW
AVERAGE PRECIPITATION ARE FAVORED THROUGH MID MONTH.
