Area forecast discussion, Sep 26, 4:29 PM CST, 2 hours 18 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SPRINGFIELD MO 529 PM CDT FRI SEP 26 2003 ...UPDATED FOR 00Z AVIATION FORECAST... .DISCUSSION... MAIN FORECAST CONCERN IS THE EVOLUTION OF THE CONVECTION ALONG A COLD FRONT NOW OVER NORTHWEST MO. SYNOPTICALLY...THINGS LOOK PRETTY STRAIGHT FORWARD. A MIDLEVEL LONGWAVE TROUGH OVER THE UPPER MIDWEST WILL DEEPEN AS A SHORTWAVE MOVES SOUTHEAST INTO THE LOWER MO RIVER VLY TONIGHT. A SURFACE COLD FRONT IN ADVANCE OF THE SHORTWAVE WILL QUICKLY MOVE SOUTHEAST THROUGH THE AREA LATE THIS AFTERNOON AND THIS EVENING. THERE HAS BEEN A DRAMATIC INCREASE IN LOW LEVEL MOISTURE SINCE YESTERDAY...WITH DEWPOINTS WELL UP INTO THE 60S ACROSS THE AREA. MLCAPES RUNNING ABOUT 800 TO 1200 J/KG OVER THE FORECAST AREA. 0-3KM SHEAR OFF THE 18Z KSGF SOUNDING NOT ALL THAT IMPRESSIVE...ABOUT 100 M2/S2. DEEP LAYER 0-6KM SHEAR ALSO NOTHING TO WRITE HOME ABOUT EITHER. HOWEVER...SHEAR PROFILES SHOULD BECOME MORE FAVORABLE FOR SEVERE WEATHER LATE THIS AFTERNOON AS THE MIDLEVEL FLOW INCREASES WITH THE APPROACH OF THE SHORTWAVE. VIS SATELLITE IMAGERY INDICATES THAT CONVECTIVE DEVELOPMENT IS INCREASING ALONG THE COLD FRONT OVER WESTERN MO/EASTERN KS AS THE FRONT MOVES SOUTH INTO INCREASING INSTABILITY. SEVERE STORMS LOOK LIKE A GOOD BET THROUGH THE EVENING HOURS...ESPECIALLY OVER THE NORTHEASTERN TWO THIRDS OF THE FORECAST AREA. SEVERE THUNDERSTORM WATCHES ARE ALREADY OUT FOR MY WESTERN AND NORTHERN COUNTIES. BEHIND THE FRONT...COOL AIR WILL STAY IN PLACE THROUGH EARLY NEXT WEEK. BY 12Z MONDAY...BOTH THE ETA AND GFS MOVE A CANADIAN SURFACE HIGH INTO SW MO/SE KS WHICH SHOULD BE OPTIMAL FOR RADIATION COOLING. HAVE UPPER 30S RUNNING FOR LOWS OVER THE OZARKS...WITH READINGS A BIT WARMER ELSEWHERE. WE MAY SEE SOME PATCHY FROST...BUT AT THIS POINT I DONT SEE A WIDESPREAD FIRST FROST MONDAY....WITH THE COLDEST AIR STAYING TO OUR NORTH AND NORTHEAST. FURTHER ON INTO THE EXTENDED...ANOTHER COLD FRONT IS PROGGED TO MOVE THROUGH THE AREA TUE. PAST MODEL PERFORMANCE HASNT BEEN TOO GOOD WITH THE DEGREE OF MOISTURE RETURN IN SOUTHERLY FLOW AHEAD THESE FRONTS LATELY. BUT FOR NOW...WILL GENERALLY BUY OFF ON THE SCENARIO THAT WEAK SURFACE RIDGING ALONG THE GULF WILL LIMIT THE AMOUNT OF MOISTURE RETURN AHEAD OF THIS NEXT FRONT AND WILL LEAVE THE MIDWEEK PERIOD DRY. HAVE ADDED RAIN CHANCES FOR FRI WITH A POSSIBLE OVERUNNING RAINFALL EVENT WITH AN APPROACHING SHORTWAVE FROM THE CENTRAL ROCKIES. && .AVIATION... LINE OF STRONG TO SEVERE CONVECTION HAS DEVELOPED ALONG STRONG COLD FRONT. FRONT WAS MOVING OUT OF CENTRAL MISSOURI INTO SOUTHEAST KANSAS AND SOUTHWEST MISSOURI AT 22Z AND MOVING SOUTHEAST AT ABOUT 40 KTS. CURRENT SPEED WOULD BRING CONVECTION INTO JLN/SGF BY 23-00Z TIME FRAME. MORE BROKEN LINE OF CONVECTION ON SOUTHWEST PORTION OF FRONT AND WILL HAVE LESS INTENSE CONVECTION IN JLN TAFS THAN IN SGF TAFS. LOOKING AT OBS UPSTREAM...WILL DROP VISIBILITIES DOWN INTO THE 1 TO 2 MILE RANGE WITH THE THUNDERSTORMS AS THEY PUSH THROUGH AND DROP CEILINGS TO AROUND 2000 FEET. QUICK MOVEMENT OF COLD FRONT AND LINE OF CONVECTION AND WILL END PRECIPITATION IN TAFS BY 02Z IN JOPLIN AND 04Z IN SPRINGFIELD. WILL PROBABLY SEE SOME MID LEVEL CLOUD COVER OVERNIGHT AND SOME STRATOCU DURING THE DAY ON SATURDAY...BUT SHOULD REMAIN VFR CONDITIONS AFTER CONVECTION ENDS THIS EVENING. && .SGF WATCHES/WARNINGS/ADVISORIES... MO...NONE. KS...NONE. PUBLIC(ALBERT)/AVIATION(LINDENBERG)
