AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SPRINGFIELD MO
1242 PM CDT THU JUN 19 2008

...UPDATE TO AVIATION...

.DISCUSSION...

MAIN FOCUS WITH THIS FORECAST PACKAGE WILL BE WITH PRECIPITATION
CHANCES AS WE REMAIN IN NORTHWEST FLOW DURING THE SHORT TERM PERIOD.

MAIN MCS ACTIVITY THIS MORNING WAS CENTERED FURTHER WEST THAN LAST
NIGHT AND WAS AFFECTING WESTERN KANSAS/OKLAHOMA INTO NORTHWEST
TEXAS. A SECONDARY AREA OF CONVECTION WAS PUSHING SOUTHEAST ACROSS
WESTERN NEBRASKA.

SHORT RANGE MODELS CONTINUE TO STRUGGLE WITH TIMING OF SHORTWAVE
ENERGY AND PRECIPITATION CHANCES ACROSS THE AREA. IT APPEARS AS IF
MOST OF THE CONVECTION WILL REMAIN WEST OF THE AREA
TODAY...ESPECIALLY THIS MORNING BEFORE INCREASED CHANCES DURING
THE AFTERNOON. ANOTHER SHORTWAVE WILL TAKE AIM AT THE AREA TONIGHT
INTO FRIDAY MORNING WHICH WILL LIKELY PROVIDE THE BEST OPPORTUNITY
FOR PRECIPITATION OVER THE CWA. HAVE GENERALLY UNDERCUT THE HIGH
MOS POPS FROM TODAY THROUGH FRIDAY TIME PERIOD DUE TO CONTINUED
UNCERTAINTY IN THE MODEL PERFORMANCE. BEST COVERAGE WILL STILL
LIKELY REMAIN TO THE WEST OF THE CWA SO WILL HAVE MY HIGHEST POPS
IN THE WESTERN CWA.

MAIN SHORTWAVE SHOULD PUSH SOUTH OF THE AREA ON FRIDAY WITH RIDGE
BUILDING FURTHER EAST HEADING INTO THE WEEKEND. FLY IN OINTMENT
MAY BE WITH SHORTWAVE ENERGY THE GFS ID BRINGING INTO EASTERN
MISSOURI ON SUNDAY.  HAVE LEFT DRY FOR NOW BUT WILL NEED TO BE
MONITORED.

SHOULD SEE A WARMING TREND OVER THE WEEKEND AND INTO EARLY NEXT
WEEK AS RIDGE BUILDS INTO THE REGION WITH TEMPERATURES HEADING TO
MORE NORMAL READINGS FOR THIS TIME OF YEAR.

.AVIATION...

FOR THE 18Z TAF PACKAGE...THE AREA HAS DESTABALIZED EARLY THIS
AFTERNOON WITH LITTLE OR NO CAP IN PLACE. THIS HAS CAUSED ISOLATED
THUNDERSTORMS TO DEVELOP INVOF SGF...AND A FEW ARE BEGINNING TO
DEVELOP IN THE JLN AREA AS WELL. THIS WILL LIKELY PERSIST THROUGH
THE AFTERNOON AND INTO THE EVENING HOURS BEFORE EVENTUALLY DYING
OFF. A CONVECTIVE COMPLEX WILL LIKELY INITIATE OVER NEBRASKA AND
KANSAS...AND MOVE SOUTH SOUTHEAST OVERNIGHT. THIS WILL LIKELY
IMPACT BOTH SGF AND JLN WITH THUNDERSTORMS...AS WELL AS LOWERED
CEILINGS WITH THE STORMS...AND POTENTIALLY IN THE WAKE OF THE
ACTIVITY AS WELL. AT THIS TIME...IT LOOKS TO CLEAR OUT BY AT
LEAST 15Z.
