NWS North Platte, NE wrote its last area forecast discussion before the first event at Aug 20, 1:58 PM CST, 5 hours 32 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE NORTH PLATTE NE 258 PM CDT MON AUG 20 2001 MAIN FORECAST CHALLENGE WILL BE PRECIP CHANCES NEXT SEVERAL DAYS. MODELS VARYING QUITE A BIT ON HEIGHT FIELDS ACROSS SOUTHWEST CONUS THIS PAST MORNING AS A RESULT OF SHORT WAVE SITTING ACROSS AZ. AVN AND NGM INITIALIZED TOO HIGH ACROSS AZ WITH THE ETA DOING THE BEST. IT COMES AS NO SURPRISE THAT THE AVN IS MUCH QUICKER AT PUSHING WAVE ACROSS AREA BY TOMORROW AFTERNOON VERSUS THE ETA. WITH WATER VAPOR IMAGERY SHOWING ONLY A SLOW DRIFT OF WAVE TO NORTHEAST...WILL FAVOR THE ETA FOR THIS FORECAST. WEAK WARM FRONT WILL EXTEND FROM NORTHEAST COLORADO INTO NORTHERN KANSAS THIS EVENING WITH LEE TROUGH EXTENDING ACROSS WESTERN PANHANDLE. STRONG MOISTURE CONVERGENCE IN PANHANDLE ALONG WITH GOOD UPPER SUPPORT FROM SHORT WAVE CURRENTLY SEEN EXITING CENTRAL ROCKIES WILL PRODUCE SCATTERED CONVECTION ACROSS WESTERN FA BY EARLY EVENING. FORCING WILL THEN SHIFT EAST INTO CENTRAL AND EASTERN CWA AS 45-50 KNOT LLJ NOSES INTO AREA DURING OVERNIGHT HOURS AND LIFTS FRONT INTO CENTRAL NEBRASKA BY SUNRISE. EXPECT CONVECTION TO FOLLOW BEST LOW-LEVEL FORCING AND WILL THEREFORE MENTION SCATTERED PRECIPITATION ACROSS ALL OF CWA TONIGHT. ANTICIPATE SURFACE LOW TO DEVELOP ACROSS NORTHEAST NEBRASKA BY AFTERNOON ON TUESDAY WITH SURFACE TROUGH/WEAK FRONT ALIGNED FROM NORTHEAST TO WEST CENTRAL CWA. MOISTURE SHOULD REMAIN DECENT ON BACK SIDE OF TROUGH/WEAK FRONT INTO THE AFTERNOON AS NEXT WAVE MOVES INTO AREA. BEST SUPPORT WOULD FAVOR A CHANCE OF TSRA ACROSS WESTERN HALF OF CWA BY AFTERNOON. EXPECT CHANCE ACROSS ALL OF AREA TUESDAY NIGHT AS WAVE SHIFTS SLOWLY FROM WEST TO EAST ACROSS CWA. FOR THIS REASON WILL BLANKET CWA WITH 30-40 POPS. HIGH TEMPERATURES WILL BE TRICKY ON TUESDAY AS 850 MB TEMPS SUGGESTING UPPER 80S NORTH TO MIDDLE 90S SOUTH DESPITE THICKNESS FIELDS DROPPING ACROSS NORTHERN AND CENTRAL ZONES. LOW-LEVEL PATTERN CHANGES LITTLE INTO WEDNESDAY AS NEXT WAVE MOVES INTO CENTRAL HIGH PLAINS. THIS SHOULD SET THE STAGE FOR ANOTHER ROUND OF SHOWERS AND THUNDERSTORMS STARTING BY LATE AFTERNOON IN THE WEST AND SHIFTING INTO THE EAST BY EARLY EVENING. WILL BLANKET AREA WITH 30-40 POPS ONCE AGAIN. TEMPERATURES SHOULD BE A FEW DEGREES COOLER FOR HIGHS AS LOW-LEVEL TEMPERATURE AND THICKNESS FIELDS LOWER. MIDDLE 80S NORTH TO AROUND 90 SOUTH LOOK GOOD AT THIS TIME. EXTENDED...MODELS AGREE ON SHIFTING UPPER LOW/TROUGH ACROSS SOUTHERN CANADA AND NORTHERN CONUS. HOWEVER...MAJOR TIMING DIFFERENCES EXIST BETWEEN THE MRF...UKMET AND ECMWF. THE MRF IS MUCH QUICKER AT EJECTING THIS SYSTEM WITH WEAK RIDGING THEN TAKING PLACE BEHIND WAVE ON DAYS 5 THROUGH 7. THE ECMWF AND UKMET ARE AROUND 24 HOURS SLOWER WITH THIS SYSTEM EVOLUTION. ENSEMBLE MEAN HEIGHT FIELDS ARE IN THE MIDDLE OF THESE TWO SOLUTIONS AND WILL LEAN TOWARDS THIS COMPROMISE FOR EXTENDED. CONDITIONS STILL LOOKING GOOD FOR PRECIP THURSDAY...BUT THEN DRY FRIDAY AND SATURDAY UNDER WEAK RIDGING. RETURN FLOW SHOULD BEGIN TO SETUP SUNDAY AND MONDAY BRINGING A CHANCE FOR RAIN BOTH DAYS AS LEE TROUGH DEEPENS ALONG FRONT RANGE REGION AND PULLS FRONT BACK NORTH ACROSS FA. .LBF...NONE. AWJ
