SEVERE WEATHER POSSIBILITY THIS EVENING...TEMPERATURES THROUGH THE WEEK...AND POSSIBLE SNOW EVENT FOR LATE IN THE WEEKEND...ARE THE MAIN FORECAST CONCERNS. FIRST BATCH OF THUNDERSTORMS MOVED OUT OF THE AREA THIS MORNING LEAVING BEHIND CLOUDS AND A RELATIVELY STABLE AIRMASS. HOWEVER THIS IS CHANGING THIS AFTERNOON AS LATEST OBJECTIVE ANALYSIS OF SURFACE DATA...SATELLITE AND RADAR SHOWS INCREASINGLY UNSTABLE AIR SURGING NORTH INTO THE CWA. LAPS ANALYSIS SHOWS 1500 J/KG CAPES JUST SOUTH OF THE KS/NE BORDER WITH AXIS OF 500-1000 J/KG EXTENDING THROUGH NORTHEAST NEBRASKA. SPCS ANALYSES ALSO INDICATE HIGH SHEAR VALUES ACROSS ALL OF THE CWA. INCREASING LAPSE RATES WERE NOTED AS MID LEVEL TROUGH PUSHES INTO THE PLAINS. VISIBLE SATELLITE PICTURES SHOWED CU FIELD BECOMING MORE ROBUST OVER THE SOUTHWEST CWA...AND RADAR WAS HINTING AT LIGHT RETURNS BEGINNING TO SHOW UP NEAR KBIE. EXPECT STORMS TO DEVELOP OVER THE SOUTHWEST CWA THEN MOVE NORTHEAST QUITE RAPIDLY.

NEXT UPPER TROUGH ADVERTISED TO MOVE INTO THE PLAINS HAS BEEN DIFFICULT TO PIN DOWN AS RUN-TO-RUN MODEL CONSISTENCY HAS BEEN LOW OVER THE LAST SEVERAL DAYS. MOST MODEL ARE NOW POINTING TO A CLOSED LOW TO MEANDER INTO THE PLAINS THIS WEEKEND WITH VARYING SOLUTIONS ON THE TRACK. WHATEVER THE CASE...IT LOOKS LIKE MILD TEMPERATURES AND RAIN WILL PREVAIL AHEAD OF THIS SYSTEM SATURDAY INTO SUNDAY.
