AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GOODLAND KS 213 PM MST SAT MAR 27 1999 MAIN CONCERN FOR THIS PACKAGE WILL BE AREAL COVERAGE OF STORMS THIS EVENING AND TEMPS IN THE OUT PERIOD. AFTERNOON TEMPS WELL INTO THE 70S ACROSS THE WESTERN PORTION OF THE CWFA WITH DEWPOINTS IN THE LOWER 40S JUST EAST OF THE COLORADO STATE LINE AT 20Z...RESULTING IN AN AIRMASS THAT IS A LITTLE MORE UNSTABLE THAN SUGGESTED BY PROGS. CONVECTIVE ECHOES BEGINNING TO APPEAR AND BECOME ORGANIZED ON RADAR/SATELLITE IMAGERY/LIGHTNING DATA WEST OF CWFA. WILL PLACE POPS AT 70 PERCENT TONIGHT FOR ALL OF CWFA UNLESS CONVECTION APPEARS TO BECOME BETTER ORGANIZED PRIOR TO ZONE ISSUANCE. WILL RUN WITH ETA/NGM BLEND FOR THIS PACKAGE WITH A LITTLE MORE WEIGHT AT LOWER LEVELS TO THE ETA GIVEN ITS BETTER TERRAIN AND HIGHER RESOLUTION. COLD FRONT PUSHES THROUGH CWFA BY 08Z...WITH DECENT LOW LEVEL SUPPORT TO KEEP WINDS IN THE BREEZY CATEGORY OVERNIGHT. WITH TURBULENT MIXING EXPECT MINS TO BE ABOUT A CATEGORY ABOVE GUIDANCE MINS. SURFACE HIGH MOVES TO EASTERN PORTION OF CWFA SUNDAY. WINDS WILL SHIFT SOUTH TO SOUTHEAST LATE IN THE AFTERNOON IN WEST AND CENTRAL PORTIONS OF THE CWFA COURTESY OF HIGH TO THE EAST AND LEE TROUGH DEVELOPING ALONG THE FRONT RANGE...BUT THESE WINDS WILL BRING IN RECYCLED COOL AIR. THIS AND THICKNESS DECREASES FROM PREVIOUS DAY SUPPORT COOL DOWN OF 10 TO 20F. MINS SUNDAY NIGHT WILL BE QUITE THE PROBLEM. SHEAR PROFILE SUGGESTS LEE TROUGH WILL BE FRAGMENTED INTO NUMEROUS LITTLE TROUGHS WITH WAVELENGTHS ON THE ORDER OF 60 MILES...RESULTING IN VARIABLE WIND DIRECTIONS AND SPEEDS. WOULD NORMALLY CUT TEMPS IN THIS SITUATION... BUT LOW LEVER THERMAL RIDGE DEVELOPS DURING THE OVERNIGHT HOURS. MOST OF NIGHT WILL PROBABLY BE SPENT A COUPLE OF CATEGORIES ABOVE THE FORECASTED MINS...BUT TEMPS WILL PLUMMET FOR A HALF HOUR OR SO DURING THE INDIVIDUAL TROUGH PASSAGES. ZONAL FLOW LOOKS TO CONTINUE INTO MONDAY WITH WARM POOL DEVELOPING IN LEE OF ROCKIES. WEST TO SOUTHWEST WINDS SHOULD SUPPLY SUFFICIENT DOWNSLOPING WARMING TO JUSTIFY USE OF FAN GUIDANCE MAXES. IN THE EXTENDED...RELATIVELY FAST ZONAL FLOWS GRADUALLY BACKS FROM WEST TO SOUTHWEST TUESDAY THROUGH THURSDAY WITH A FRONTAL SYSTEM APPROACHING LATE IN THE DAY. PREFRONTAL TROUGH OR DRYLINE MAY SWEEP LOW LEVEL MOISTURE OFF TO THE EAST BEFORE TIME OF MAX HEATING AND ARRIVAL OF BEST DYNAMICS...SO WILL NOT MENTION PRECIP AT THIS TIME FOR DAY 5. PATTERN LOOKS LIKE A DRY ONE WITH ABOVE NORMAL TEMPS FOR THE PERIOD. ALTHOUGH HEIGHTS AND THICKNESSES SEEM TO DECREASE ON THURSDAY IN RESPONSE TO SHORTWAVES EJECTING AHEAD OF NEXT NORTHWEST U.S. LOW...THIS SEEMS OVERDONE GIVEN THE STRENGTH OF RIDGES THAT HAVE DEVELOPED AHEAD OF THESE SYSTEMS IN THE PAST. WILL OPT TO KEEP THURSDAY AS WARM AS TUESDAY AND WEDNESDAY AT THIS POINT. .GLD...NONE. ENTWISTLE
