AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE KANSAS CITY/PLEASANT HILL MO
225 AM CDT TUE APR 3 2007

.DISCUSSION...

MAIN FOCUS IN THE SHORT TERM IS WITH ONGOING STRONG CONVECTION
BEHIND AN OUTFLOW BOUNDARY THAT ORIGINATED OVER SOUTHEAST NEBRASKA
AND CONTINUES TO ADVANCE EAST/SOUTHEAST ACROSS NORTHEAST KANSAS AND
NORTHWEST MISSOURI. MEANWHILE...THE SURFACE LOW CONTINUES TO
PROGRESS NORTHEAST ALONG THE WARM FRONT...WITH THE TRAILING COLD
FRONT LOCATED FROM WEST CENTRAL KANSAS THROUGH THE PANHANDLES OF
OKLAHOMA AND TEXAS EARLY THIS MORNING. IN ADDITION TO THE ONGOING
CONVECTION JUST BEHIND THE OUTFLOW BOUNDARY...CONVECTION IS EXPECTED
TO DEVELOP BACK ALONG THE COLD FRONT THIS MORNING. SHORT RANGE
FORECAST MODELS AND ANTICIPATED FRONTAL TIMING INDICATE THE SHOWERS
AND THUNDERSTORMS WILL PUSH EAST OF THE FORECAST AREA...ALONG WITH
THE COLD FRONT...FROM MID TO LATE MORNING. JUST LEFT A SLIGHT CHANCE
FOR SOME LINGERING ACTIVITY IN THE FAR EASTERN SECTION THROUGH EARLY
AFTERNOON.

THEN THE STORY TURNS TO THE COLDER TEMPERATURES IN THE WAKE OF THE
COLD FRONT. TEMPERATURES ACROSS THE FORECAST AREA WILL REACH THEIR
MAXIMA EARLY IN THE DAY AND BECOME STEADY/FALL FROM NORTHWEST TO
SOUTHEAST BY THIS AFTERNOON. COLD AIR ADVECTION WILL CONTINUE
TONIGHT...WITH TEMPERATURES EXPECTED TO FALL AT OR BELOW FREEZING
ACROSS ALL BUT PORTIONS OF EAST CENTRAL KANSAS/CENTRAL MISSOURI. THE
GREATEST AREA OF CONCERN FOR A HARD FREEZE IS FAR NORTHERN AND NORTH
CENTRAL MISSOURI. A REINFORCING SURGE OF COLD AIR IS FORECAST
THURSDAY NIGHT AS THE RATHER IMPRESSIVE SURFACE RIDGE BUILDS EVEN
FURTHER SOUTH.

BOTH THE NAM AND GFS SHOW PRECIPITATION DEVELOPING SOUTHEAST FROM
SOUTHERN NEBRASKA AND CLIPPING THE SOUTHWEST PORTION OF THE FORECAST
AREA THURSDAY AFTERNOON/NIGHT. STILL NOT OVERLY CONFIDENT ON THE
PLACEMENT OF THE RESPONSIBLE SHORTWAVE DIVING SOUTHEAST IN THE
NORTHWEST FLOW ALOFT...SO HAVE KEPT JUST CHANCE MENTION OF
PRECIPITATION. FORECAST SOUNDINGS STILL APPEAR CONDUCIVE FOR
PRECIPITATION TO AT LEAST BECOME MIXED WITH SNOW...HOWEVER AMOUNTS
APPEAR TO BE LIGHT WITH GREATER QPF TO OUR WEST. NO OTHER CHANGES
MADE FROM FRIDAY ON.

STOFLET

&&

.AVIATION...

FOR THE 06Z TAFS...KEEPING AN EYE ON CONVECTION DEVELOPING UPSTREAM
ACROSS SOUTHEASTERN NEBRASKA. OUTFLOW BOUNDARY JUST NOW PUSHING INTO
NORTHERN KANSAS AND EXTREME SOUTHEASTERN NEBRASKA...AND SHOULD PUSH
INTO NW MISSOURI WITHIN THE NEXT HALF HOUR. CURRENTLY THINKING THIS
BOUNDARY WILL PUSH INTO THE KSTJ TERMINAL NEAR 8Z AND INTO THE KMCI
TERMINAL NEAR 9-10Z. MOST OF THE CONVECTION HAS DEVELOPED BEHIND
THIS BOUNDARY SO FAR AND THINK THIS WILL STAY THE TREND FOR THE MOST
PART. ANY STORMS THAT DO DEVELOP WILL HAVE THE CHANCE TO BECOME
SEVERE WITH THE MAIN THREATS BEING HAIL AND STRONG DAMAGING WINDS.
BEHIND THE BOUNDARY...EXPECT WINDS TO SHIFT TO MORE OF A NORTHERLY
DIRECTION.

OTHERWISE...CONTINUED WITH LLWS AS LLJ CONTINUES TO STRENGTHEN WITH
AROUND 50KTS AT THE TOP OF THE INVERSION. COLD FRONT IS STILL
PROGGED TO PUSH THROUGH THE AREA FROM 12-15Z WITH STRONG
NORTHWESTERLY WINDS ON THE BACK SIDE.

400 PM CDT MON APR 2 2007

THIS HAZARDOUS WEATHER OUTLOOK IS FOR NORTHWEST...NORTH CENTRAL
AND WEST CENTRAL MISSOURI...AS WELL AS EXTREME EASTERN KANSAS.

.DAY ONE...REST OF THIS AFTERNOON AND TONIGHT

STRONG SOUTHERLY FLOW WILL CONTINUE THIS EVENING...MAKING THE
AIRMASS INCREASINGLY UNSTABLE. MUCH WARMER TEMPERATURES ALOFT WILL
KEEP THUNDERSTORMS AT BAY ACROSS EASTERN KANSAS AND MISSOURI DURING
THE EVENING. HOWEVER...A STRONG COLD FRONT IS EXPECTED TO MOVE INTO
NORTHERN MISSOURI AFTER MIDNIGHT...BRINGING A CHANCE OF
THUNDERSTORMS TO THE OUTLOOK AREA AT THAT TIME. A FEW OF THE
THUNDERSTORMS MAY BE SEVERE AFTER MIDNIGHT...MAINLY ALONG AND NORTH
OF A LINE FROM ST JOSEPH TO KIRKSVILLE. THE PRIMARY THREAT IS LARGE
HAIL...ALTHOUGH AN ISOLATED THUNDERSTORM MAY PRODUCE DAMAGING WINDS.

.DAYS TWO THROUGH SEVEN...TUESDAY THROUGH SUNDAY

THE COLD FRONT WILL CONTINUE TO MOVE SOUTH ACROSS MISSOURI ON
TUESDAY...CONTINUING THE CHANCE FOR THUNDERSTORMS. THE THUNDERSTORMS
ARE NOT EXPECTED TO BE SEVERE DURING THE MORNING HOURS...BEFORE THE
FRONT MOVES INTO SOUTHERN MISSOURI BY THE AFTERNOON.

MUCH COOLER WEATHER IS EXPECTED BEHIND THIS FRONT FOR THE REMAINDER
OF THE WEEK. EARLY MORNING FREEZING TEMPERATURES ARE POSSIBLE
THURSDAY THROUGH SUNDAY. WHILE THE AVERAGE LAST SPRING FROST
GENERALLY DOES NOT OCCUR UNTIL THE MIDDLE OF APRIL...UNSEASONABLY
WARM TEMPERATURES DURING THE MONTH OF MARCH HAVE CAUSED ACCELERATED
GROWTH OF VEGETATION AROUND THE REGION. PERSONS ACROSS THE AREA
SHOULD BE PREPARED TO PROTECT TENDER PLANTS FROM FROST AND FREEZE
DAMAGE BY THE END OF THE WEEK.

.SPOTTER INFORMATION STATEMENT...

SPOTTER ACTIVATION MAY BE NEEDED AFTER MIDNIGHT ALONG AND NORTH OF A
LINE FROM ST JOSEPH TO KIRKSVILLE.
