AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SPRINGFIELD MO
316 AM CDT FRI JUL 9 2004

.DISCUSSION...
GREETINGS FROM THE VALLEY OF MCVS. ANOTHER VERY CHALLENGING FORECAST
THIS MORNING AS WELL DEFINED MCV JUST SOUTH OF SGF SEEMS TO BE GOING
NOWHERE FAST, WHILE HUGE MCS MOVING INTO EASTERN KANSAS AND NEBRASKA
HAS GENERATED A STRONG COLD POOL AND ANOTHER MCV WILL LIKELY EMERGE
LATER THIS MORNING. HOW THESE 2 FEATURES INTERACT IS THE KEY TO
TODAYS FORECAST. SOUTHERN EDGE OF KANSAS MCS SHOULD PROPAGATE SSE TO
SOUTH AS LLJ VEERS THIS MORNING. THINK THAT EASTERN EDGE OF
WEAKENING CONVECTION SHOULD MOVE INTO SE KANSAS BY AROUND 12Z, BUT
HOW THIS LINE REACTS TO WELL DEFINED AND DEEP EASTERLY MID LEVEL
FLOW AROUND SGF MCV IS UNKNOWN. IN ANY CASE, SLIGHTLY ELEVATED CAPE
OF AROUND 1200 J/KG WILL LAST BEYOND DAWN AS REMNANTS OF LINE
APPROACH, SO THINK AT LEAST HI CHANCE POPS WARRANTED ACROSS NWRN CWA
THIS MORNING. FOR LATER IN THE DAY, 06Z ETA DOES INITIALIZE BOTH
MCVS WELL, AND DOES A FUJIWARA STYLE INTERACTION, BRINGING THE SGF
VORT A BIT NORTH WHILE THE KANSAS VORT SLIDES SWD INTO CENTRAL OK.
STEEP LAPSE RATES YIELD MIDDAY ML CAPES OF OVER 1000 J/KG EVEN WITH
MODEST RECOVERY OF SURFACE TEMPS TO THE UPPER 70S. THINK SCATTERED
CONVECTION A GOOD BET THROUGH THE AFTERNOON, ESPECIALLY OVER THE WRN
HALF OF THE CWA CLOSEST TO THE MCVS. WILL CONTINUE FLOOD WATCH IN SE
KANSAS AND FAR SW MO COUNTIES. OVERNIGHT CONVECTION DID NOT
MATERIALIZE, BUT AM LEARY OF CANCELLING WATCH ATTM WITH KANSAS MCS
APPROACHING.

WEAKNESS IN THE 500 MB SUBTROPICAL RIDGE CONTINUES OVER AREA THROUGH
SATURDAY NIGHT, AND WITH LACK OF CAP, THINK THAT PULSE TYPE
THUNDERSTORMS ARE A GOOD BET SATURDAY. 06Z ETA SOUNDING BROUGHT TO
85/70 YEILDS SBCAPE OF 2500 J/KG SATURDAY AFTERNOON WITH NO CAP. ETA
CONTINUES TO SHOW REMNANTS OF MCV OVER AREA, AND EVEN WEAK FORCING
COULD EASILY TRIGGER CONVECTION IN SUCH AN UNSTABLE AND UNCAPPED
ATMOSPHERE.

MID LEVEL TROUGH FILLS A BIT ON SUNDAY AS THICKNESSES INCREASE 10 TO
20 GPM, BUT CHANCE POPS STILL LOOK WARRANTED AS BL AIRMASS CHANGES
LITTLE AND TROUGH IS STILL EVIDENT. 00Z GFS AND ECMWF RUNS SHOW A
WARMUP EARLY IN THE WORK WEEK AS HEIGHTS BUILD, THEN THE RIDGE GETS
BEATEN DOWN BY 00Z FRIDAY AND A COLD FRONT EDGES INTO THE AREA.

.AVIATION...
MCV OVER SOUTHERN MO IS DRIFTING ONLY VERY SLOWLY SOUTH TONIGHT.
PROFILERS INDICATE A 35 KNOT 850MB JET EXTENDING FROM THE RED RIVER
INTO NORTHEAST KS AND NW MO. ANOTHER CONVECTIVE COMPLEX CONTINUES TO
PUSH SOUTHEAST AT 30 TO 40 KNOTS INTO EAST CENTRAL KANSAS TAKE AIM
AT THE KSGF/KJLN AGAIN TOWARDS SUNRISE WITH GUSTY WINDS AND
