HAVING FLASHBACKS TO YESTERDAY WITH BOUNDARY CURRENTLY ACROSS FORECAST AREA EXTENDING FROM KSPW TO KSUX. SOUTH OF THE BOUNDARY...AREAS WARMED MUCH MORE THAN ANTICIPATED WITH HIGHS IN THE 90S IN NW IOWA. EXPECT BOUNDARY TO WORK OUT OF THE AREA EARLY THIS EVENING...WITH DRIER AIR FILTERING IN BEHIND. EXTENSIVE AMOUNT OF CIRRUS WILL GRADUALLY SPREAD OVER THE AREA TONIGHT IN ADVANCE OF MONSOONAL WAVE MOVING OUT OF COLORADO AND WYOMING. MODELS HANDLING THIS WAVE VERY DIFFERENTLY...ADDING TO THE COMPLEXITY OF THE FORECAST. GFS DEVELOPS CONVECTION DOWN IN KANSAS...LOWERS THE HEIGHTS AS A RESULT CAUSING ADDITIONAL CONVECTION TO DEVELOP TO THE SOUTH CUTTING OFF THE MOISTURE SUPPLY TO THE FORECAST AREA. THE NAM BRINGS THE WAVE FURTHER NORTH ACROSS NEBRASKA ALLOWING AREA TO TAP INTO BETTER MOISTURE AND PRECIPITATION. HAVE SIDED MORE WITH THE NAM...WHICH IS ALSO SUPPORTED BY THE ECMWF.

WAVE SLIDES ACROSS NEBRASKA CREATING THE POTENTIAL FOR PRECIP ACROSS PORTIONS OF FORECAST AREA...WITH THE BEST CHANCES IN NORTHWEST IOWA. NEW 18Z RUN HAS THE WAVE SLIGHTLY FURTHER SOUTH CLOSER TO THE CANADIAN GEM SOLUTION...WHICH MAY SUGGEST MUCH OF THE AREA MISSES OUT ON PRECIP EVENT ALL TOGETHER. TEMPERATURES VERY TRICKY WITH THIS SYSTEM...AS THEY WILL BE STRONGLY DEPENDANT ON AMOUNT OF CLOUD COVER ACROSS THE AREA. HAVE FOCUSED HIGHEST TEMPERATURES IN THE WEST...WHERE CHANCES OF PRECIP ARE FAIRLY MINIMAL. THEREAFTER...A SIGNIFICANT HEAT WAVE WILL IMPACT THE AREA FROM WEDNESDAY ON. HAVE ADDED MENTION TO HWO...BUT FORECAST HIGHS CONSERVATIVELY WILL RANGE FROM THE LOWER 90S TO THE MID 100S...WITH THE WARMEST READINGS IN CENTRAL SOUTH DAKOTA. HAVE RAISED FORECASTED HIGHS SOME...AND WITH SOUTHERLY FLOW BECOMING ESTABLISHED AND THE GULF OPENING UP...HAVE RAISED DEW POINTS INTO THE UPPER 60S TO NEAR 70.
