Area forecast discussion, Aug 21, 1:44 PM CDT, 7 hours 2 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GOODLAND KS 1244 PM MDT (144 PM CDT) THU AUG 21 1997 BIGGEST CHALLENGE TODAY IS ONCE AGAIN POPS FOR THE FIRST PERIOD. 18Z ADAP DATA SHOWS NO CAP...LI OF -11...AND STRONG MOISTURE CONVERGENCE ALONG AN IML-DDC LINE. THIS BOUNDARY WAS PRODUCED BY SEVERE STORMS OVER CENTRAL NEBRASKA EARLY THIS MORNING. WILL EXPECT TS TO START DEVELOPING FAIRLY EARLY ON THIS AFTERNOON NEAR THIS BOUNDARY. ANOTHER BOUNDARY EXTENDS FROM IML SOUTHWESTWARD TO NEAR LHX...BUT DEW POINTS ARE A BIT LOWER ALONG WESTERN BOUNDARY AND IT MAY TAKE AN ADDITIONAL SOURCE OF LIFT TO BREAK CAP ACROSS WRN ZNS. OTHER KEY PLAYER IS SHORT WAVE OVER NWRN NEBRASKA. MODELS CONSISTENT IN MOVING WAVE SOUTHEAST INTO NERN FA BY LATE AFTERNOON. DRYING BEHIND THIS FEATURE IS QUITE IMPRESSIVE ON WATER VAPOR IMAGERY...WHILE ETA PROGS PW VALUES OF OVER 1.5 INCHES OVER SERN FA BY 00Z THIS EVENING. FFG IS RELATIVELY LOW OVER ERN ZNS...BUT NOT YET CONFIDENT ON POTENTIAL COVERAGE SO WILL NOT FAVOR FFA AT THIS TIME...BUT EVENING SHIFT WILL NEED TO WATCH CLOSELY. FAIRLY STRONG MID-LEVEL NORTHWEST WINDS REMAIN IN PLACE AND WIND SHEAR MAY ADD TO SEVERE POTENTIAL. TOMORROW AND TOMORROW EVENING...ETA FORECAST CAPES ARE ONCE AGAIN QUITE INPRESSIVE ACROSS CENTRAL AND EASTERN FA. LITTLE EASTWARD PROGRESS OF MAIN TROUGH CURRENTLY OVER REGION SHOULD LEAD TO THE BEST CHANCES OF PRECIP IN CENTRAL FA...THOUGH LESS TODAY GIVEN THE LACK OF DYNAMICS. WILL RETAIN SLIGHT CHANCE POPS ON SATURDAY AS ETA FORECAST LAPSE RATES DECREASE SLIGHTLY AS LOWER LEVELS WARM. TIMING OF FAST MOVING NORTHWEST FLOW SHORTWAVES AND POSSIBLE MODEL UNDERESTIMATION OF MONSOON MOISTURE TO OUR WEST MAKES IT DIFFICULT TO ELIMINATE AFTERNOON POPS ANYWHERE IN FA. .GLD...NONE. BARKER
