AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SPRINGFIELD MO 130 AM CDT SUN MAY 2 2004 .DISCUSSION... FORECAST CONCERNS: DENSE FOG THIS MORNING...SHOWERS/THUNDER THIS AFTERNOON AND FROST POTENTIAL MONDAY MORNING. VIS/FOG SATELLITE PICTURE SHOWING AN ENHANCED AREA OF LOW CLOUDS/FOG DEVELOPING OVER FAR SOUTHWEST MISSOURI AS OF 1 AM. GROVE OKLAHOMA AND NORTHWEST PORTIONS OF ARKANSAS ALREADY AT A QUARTER OF A MILE. WILL MAKE SOME CALLS THIS MORNING AS TO WHETHER TO ADD A DENSE FOG ADVISORY...OR LEAVE PATCHY DENSE FOG IN THE ZONES INSTEAD. UPSTREAM SHORT WAVE ALREADY PRODUCING A BAND OF MID LEVEL CLOUDS AND SOME WEAK REFLECTIVITY RETURNS OVER SOUTHERN NEBRASKA AND NORTHERN KANSAS. MODELS HAVE BEEN ADVERTISING AN INCREASE IN AREAL COVERAGE AND QPF AMOUNTS FOR THE PAST SEVERAL RUNS...AND THIS SEEMS REASONABLE DUE TO THE STRENGTH OF THE UPPER SHORT WAVE...SHARP 50H TEMPS...AND STEEP LAPSE RATES BY THIS AFTERNOON OVER THE FORECAST AREA. CROSS SECTIONS OVER THE AREA DOES INDICATED ENOUGH INSTABILITY TO PRODUCE AN ISOLATED THUNDERSTORM OR TWO. ANYWAY...THIS SHORT WAVE QUICKLY MOVES SOUTHEAST OF THE AREA BY THIS EVENING WITH STRONG SUBSIDENCE IN ITS WAKE. LATEST MODEL INFORMATION FOR MONDAY MORNING MAY INDICATE ENOUGH MIXING IN LOW LEVELS TO KEEP SURFACE WINDS FROM DECOUPLING. HOWEVER...GRADIENT IS NOT STRONG AND ANY COLD AIR ADVECTION ENHANCEMENT SHOULD KEEP AS LEAST THE SHELTERED VALLEYS AND LOW LYING AREAS TO FALL INTO THE LOW TO MID 30S. WILL KEEP PATCHY FROST IN THE ZONES...BUT LATER SHIFTS WILL NEED TO LOOK AT ADDITIONAL INFORMATION AND SEE IF A FROST ADVISORY IS WARRANTED. THE UPPER LEVEL FLOW BECOMES LESS AMPLIFIED BY MID WEEK. HOWEVER...ANOTHER COLD FRONT MOVES AS FAR SOUTH AS NORTHERN MISSOURI BY TUESDAY NIGHT/WEDNESDAY. HAVE INCREASED CLOUD COVER A BIT...BUT WITH THE UPPER FLOW WNW...AND BECOMING INCREASINGLY WESTERLY...DONT BELIEVE THE COLD FRONT WILL MOVE INTO SOUTHERN MISSOURI AT THIS TIME. NO CHANGES IN THE EXTENDED PERIOD WITH THE MAIN JET AXIS ACROSS THE NORTHERN PLAINS. THEREFORE...DONT SEE ANY SIGNIFICANT CHANCE OF PRECIPITATION AFTER TOMORROW THROUGH THE NEXT 5 TO 7 DAYS. JLT && .AVIATION... HAVE ALREADY ADDED SOME FOG TO THE KSGF AND KJLN TAFS FOR THE OVERNIGHT PERIOD. OTHERWISE...FOG SHOULD BURN OFF FAIRLY QUICKLY SUN MORNING...BUT DIURNAL CUMULUS SHOULD QUICKLY DEVELOP LATE IN THE MORNING. HAVE ADDED A PROB30 FOR SHOWER ACTIVITY SUN AFTERNOON. CLOUD BASES SHOULD GENERALLY BE VFR DURING THAT TIME. DSA && .SGF WATCHES/WARNINGS/ADVISORIES... .MO...NONE. .KS...NONE. WFO SGF
