Area forecast discussion, Jun 26, 2:06 PM MDT, 8 hours 56 minutes before
GOODLAND FORECAST DISCUSSION NATIONAL WEATHER SERVICE GOODLAND KS 206 PM MDT SAT JUN 26 1999 POPS ARE GREATEST CHALLENGE FOR THIS PACKAGE. HAVE CHOSEN ETA/ECMWF BLEND FOR PERIOD 1 THROUGH DAY 5 PORTION OF PACKAGE WITH A LITTLE WEIGHT GIVEN TO NGM FOR PERIOD 1 BASED ON INITIALIZATION OF MASS AND MOISTURE. SCENARIO IS BEING SET WITH INCREASING FLOW ALOFT ASSOCIATED WITH SHORTWAVE AIDING THE FLATTENING OF THE UPPER WESTERN U.S. RIDGE. AT 1940Z CU WERE BEGINNING TO DEVELOP ALONG MAIN FRONTAL BOUNDARY ROUGHLY FROM KLBF TO KSNY. EXPECT TSRA TO INITIATE NORTHWEST OF THE CWFA AND SOME TYPE OF CONVECTIVE CLUSTER TO MOVE ALONG THE KS/NEB STATE LINE OVERNIGHT. OTHER ACTIVITY IS POSSIBLE SOUTH OF CLUSTER AS NUMEROUS OLD BOUNDARIES LIE OVER THE CWFA. A SECOND MCS COULD BEGIN IN THE EASTERN CWFA AND MOVE SOUTH SOUTHEAST. LOWEST COVERAGE LIKELY TO BE IN SOUTHWEST CWFA WHERE 700 MB TEMPS ARE PROGGED TO REMAIN ABOVE 14C...ALTHOUGH MESOSCALE INTERACTIONS WITH TSRA TO THE NORTH COULD COOL THAT AREA ENOUGH TO ALLOW CONVECTION TO SURVIVE. WILL HAVE TO WAIT AND SEE. 3 HOUR FLASH FLOOD GUIDANCE RANGES FROM 2.0 INCHES AROUND KHLC TO 3.4 INCHES IN EXTREME SOUTHWEST NEBRASKA...SO WILL NOT ISSUE ANY TYPE OF FLOOD WATCH AT THIS TIME AND LET THE EVENING SHIFT EVALUATE BASED ON WHERE THE STORMS GO. MUCH OF THE AREA WILL BE CLOUDY WITH AREAS OF FOG BY THE EARLY MORNING HOURS IN THE WAKE OF MCS ACTIVITY AND UPSLOPE FLOW RETURNING. THIS SHOULD COOL TEMPS A BIT FROM TODAYS MAXES. HEIGHTS LOWER ONCE AGAIN IN RESPONSE TO ANOTHER SHORTWAVE IN THE FLATTENED FLOW WITH MID LEVEL VORTICITY GENERATION PROGGED TO OCCUR ALONG THE COLORADO FRONT RANGE. BELIEVE MOST STORMS WILL BE WEST OF THE COLORADO PORTION OF THE CWFA...BUT CONVERGENT TROUGH WILL BE CLOSE ENOUGH TO WARRANT A MENTIONABLE POP. SHORTWAVE CONTINUE TO MOVE OVER THE AREA SUNDAY NIGHT INTO MONDAY... WITH MAX TEMPS COOLER BY A CATEGORY OR SO ON MONDAY THAN ON SUNDAY. LOWS BASED ON PROGGED BOUNDARY LAYER DEWPOINTS. IN THE EXTENDED...BLENDED ECMWF AND UKMET FOR PROGS. CHANCE POPS MONDAY NIGHT ALL AREAS. CHANCE TSRA FOR COLORADO COUNTIES ON TUESDAY WITH CHANCE ALL OF CWFA WEDNESDAY. COULD STILL HAVE SOME LEFTOVER SHOWERS THURSDAY...BUT FRONTAL BOUNDARY LOOKS TO BE ALL THE WAY TOWARD RED RIVER VALLEY WEDNESDAY WHILE ENERGY EJECTS FROM TROUGH MOVING OVER THE CWFA. TEMPS NEAR NORMAL TUESDAY AND THEN BELOW NORMAL WEDNESDAY AND THURSDAY. .GLD...NONE. ENTWISTLE
