Area forecast discussion, May 1, 2:20 AM CDT, 7 hours 35 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SPRINGFIELD MO 220 AM CDT WED MAY 1 2002 INTERESTING WEATHER SCENARIO TO PLAY OUT TODAY AND TONIGHT ACROSS THE OZARKS. CURRENTLY WAITING FOR CONVECTION TO DEVELOP ACROSS SOUTHEAST KANSAS/SOUTHWEST MISSOURI. PROFILERS SHOW 850 LOW LEVEL JET BEGINNING TO SET UP OVER THE LAST SEVERAL HOURS ACROSS OKLAHOMA INTO SOUTHERN KANSAS. AT THE SURFACE...STATIONARY BOUNDARY ACROSS CENTRAL MO WITH WARM FRONT TO THE SOUTH ACROSS ARKANSAS. DEW POINTS ACROSS THE CWA WERE IN THE LOW 60S...WHILE SOUTH OF THE WARM FRONT IN THE UPPER 60S TO AROUND 70. DENSE FOG HAS FORMED OVER THE AREA IN SOUTHERN MISSOURI IN BETWEEN THE FRONTS...WHERE WEAK WIND FIELD WAS OBSERVED...AND CLOUDS ALOFT HAVE PUSHED OUT OF THE AREA. WE ISSUED A DENSE FOG ADVISORY EARLIER AND WILL CONTINUE THIS UNTIL 9 AM. LOOKS LIKE A COUPLE OF ROUNDS OF CONVECTION TODAY/TONIGHT ACROSS THE CWA. STILL EXPECT CONVECTION TO FIRE ACROSS SOUTHEAST KANSAS/SOUTHWEST MISSOURI IN NEXT SEVERAL HOURS...WITH NOSE OF LOW LEVEL JET INTO THE AREA. CORFIDI VECTORS WOULD INDICATE MCS TO PUSH DUE EAST ACROSS THE SOUTHERN CWA THIS MORNING. HAIL WOULD BE THE MAIN THREAT WITH THIS ELEVATED CONVECTION NORTH OF THE WARM FRONT. MAIN QUESTION FOR THIS AFTERNOONS ROUND 2 WILL BE HOW MUCH CLEARING WILL TAKE PLACE TO INCREASE THE INSTABILITY. SURFACE LOW CURRENTLY OVER SOUTHWEST KANSAS IS EXPECTED TO INTENSIFY AND PUSH EAST INTO SOUTWHEST MISSOURI EARLY THIS AFTERNOON. WARM FRONT SHOULD LIFT NORTHWARD INTO SOUTHERN MISSOURI AFTER MCS PUSHES TO THE EAST OF THE AREA BY LATE MORNING. THIS WILL ALSO HELP BRING DEW POINTS UP INTO THE UPPER 60S TO LOW 70S INTO SOUTHERN MISSOURI. BELIEVE SOME CLEARING WILL TAKE PLACE THIS AFTERNOON AS THE WARM FRONT MOVES THROUGH...ESPECIALLY IN THE WESTERN CWA. WILL HAVE THE WARMEST TEMPERATURES IN THE WEST...AND THE COOLEST IN THE EAST. IF CLEARING TAKES PLACE...ATMOSPHERE WILL RAPIDLY DESTABILIZE...WITH AFTERNOON CAPES FROM 4000-5000 J/KG EXPECTED. WITH THE LOW MOVING INTO THE AREA...WINDS WILL BEGIN TO BACK AND INCREASE THE SHEAR VALUES IN THE LOWER LEVELS OF THE ATMOSPHERE. WITH LOW TEMPERATURE/DEW POINT DEPRESSION...ATMOSPHERE WILL BE FAVORABLE FOR SUPERCELLS AND TORNADIC DEVELOPMENT LATE THIS AFTERNOON INTO THIS EVENING...ESPECIALLY IN EASTERN HALF OF CWA. SPC HAS HIGHLIGHTED THIS AREA IN A MODERATE RISK FOR TODAY...AND WILL MENTION POSSIBILITY OF SEVERE WEATHER IN ZONES. COLD FRONT PUSHES THROUGH THE CWA TONIGHT AS NORTHERN STREAM WAVE DIGS SOUTH INTO THE UPPER MISSISSIPPI VALLEY. CONVECTION WILL BE ONGOING AHEAD OF THE FRONT WHICH SHOULD MOVE THROUGH THE ENTIRE CWA BY 12Z. HIGH PRESSURE THEN BUILDS INTO THE AREA ON THURSDAY WITH UPPER LEVEL LOW SHIFTING INTO THE GREAT LAKES. MUCH COOLER AIR MOVES INTO THE AREA AT 850...AND SHOULD ONLY SEE HIGHS REACH THE UPPER 50S TO LOW 60S. NEXT CHANCE OF CONVECTION LOOKS TO BE SATURDAY NIGHT INTO SUNDAY WHEN ANOTHER MCS EXPECTED TO DEVELOP OVER AR/S MO. LOOK FOR TEMPS TO MODERATE TO MORE NORMAL READINGS UNTIL THEN. ISC TEMPERATURE GRIDS ALREADY SENT. HOPE TO HAVE THE FULL SET BY 3 AM CDT. .SGF... MO...DENSE FOG ADVISORY FOR THIS MORNING FOR ZONES MOZ077... MOZ079>082...MOZ088>098...MOZ101>106.
