A 1016 HPA SURFACE HIGH PRESSURE ACROSS TEXAS INTO EASTERN
KANSAS THIS MORNING IS FORECAST TO SLIDE OFF EAST INTO THE
SOUTHERN MISSISSIPPI VALLEY, ALLOWING AN INCREASE TO THE
SURFACE PRESSURE GRADIENT ACROSS WESTERN KANSAS THIS AFTERNOON.
SOUTHERLY WINDS WHILE NOT STRONG WILL STILL BE FREQUENTLY
GUSTING TO THE MID 20’S (KNOTS) OR NEARLY 30 MPH. TEMPERATURES
BOUNCE BACK WITH FAIRLY HIGH CONFIDENCE OF HITTING NEAR 80S
DEGREES (79 TO 82 IS THE REASONABLE RANGE OF OUTCOMES AT DODGE
CITY).
CONVECTION COULD DEVELOP ANYTIME BETWEEN LATE TUESDAY THOUGH
ABOUT FRIDAY AT WHICH POINT ANOTHER COLD FRONT WILL MOVE
THROUGH, BRINGING COOLER 60S FOR HIGHS AGAIN TO START OUT THE
NEXT WEEKEND. A MARGINAL RISK FOR SEVERE WEATHER INCLUDING LARGE
HAIL EXISTS OVER THE SOUTHEAST HALF OR SO OF THE AREA TUESDAY
AFTERNOON AND EVENING. THIS ARE WILL BE UNDER THE INFLUENCE OF
FAST ZONAL FLOW N THE MID LEVELS AND AN INVERTED SURFACE
TOUGH/SURFACE LOW EXTENDING FROM NE NM INTO SOUTHWEST/SOUTHCENTRAL
KANSAS. MEAN SURFACE BASED CAPE IN EXCESS OF 1000 J/KG IS
POSSIBLE SOUTH OF HIGHWAY 54 TUESDAY AFTERNOON.
BY WEDNESDAY AFTERNOON, LESS OF A FOCUS AREA FOR CONVECTION AS
FAR AS OBVIOUS SURFACE BOUNDARIES EXIST, HOWEVER WEAK FORCING
ALOFT MAY STILL BE IN PLACE WITH THE DEVELOPING SOUTHWEST FLOW
ALOFT. MUCH MORE SIGNIFICANT PRECIPITATION PROBABILITIES
(60-85%) COME INTO THE FORECAST BY THURSDAY AFTERNOON AS THE
UPPER FLOW REMAINS BUCKLED OVER THE WESTERN STATES ALLOW
DIFLUENT FLOW ALOFT ACROSS THE CENTRAL ROCKIES AND WESTERN
PLAINS, AS THE NEXT COLD AIRMASS INVADES THE SOUTHERN HIGH
PLAINS FROM THE NORTHERN PLAINS THROUGH FRIDAY AFTERNOON. HERE,
THUNDERSTORMS MIGHT TURN TO A STRATIFORM RAIN EVENT BEGINNING IN
EARNEST THURSDAY EVENING AND ENDING.
