AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE DES MOINES IA
645 PM CDT TUE APR 8 2008

UPDATED AVIATION DISCUSSION.

.DISCUSSION...
AN ACTIVE WEATHER PATTERN REMAINS IN PLACE FOR CENTRAL IOWA THROUGH
THE WEEKEND.  WITH REGARD TO THE CURRENT SYSTEM...THE SURFACE LOW
HAS MOVED LITTLE DURING THE DAY AND IS STILL OVER EAST CENTRAL
MISSOURI AT 3 PM.  THE FRONTAL BOUNDARY IS WELL OFF INTO CENTRAL
ILLINOIS AND WE ARE ON THE COLD SIDE OF THE SYSTEM AS EVIDENCED BU
THE BRIEF MIX OF RAIN AND SNOW.  THE MODELS OVERDID THE LIFT WITH
THIS SYSTEM AND WHILE A FEW LOCATIONS OVER THE SOUTHEAST GOT A HEFTY
AMOUNT OF RAINFALL...WIDESPREAD HEAVY RAIN DID NOT OCCUR.
DEFORMATION ZONE PRECIP IS NOW SETTING UP AND EVIDENT ON RADAR.
THIS IS IN THE FORM OF MAINLY WIDESPREAD PRECIP WITH SOME ISOLATED
HEAVIER BANDING OF PRECIP...AND ALL IN THE FORM OF RAIN.  THE SYSTEM
SHOULD DEPART CENTRAL IOWA BY LATE EVENING.

A FAIRLY TRANQUIL DAY IS IN STORE FOR CENTRAL IOWA TOMORROW AS WE
GET WEAK RIDGING ALOFT AND HIGH PRESSURE AT THE SURFACE OVER CANADA
NOSES DOWN TO OUR EAST.  THE RESPITE WILL BE BRIEF HOWEVER AS WATER
VAPOR ALREADY SHOWING THE NEXT SYSTEM ON BOARD TO AFFECT CENTRAL
IOWA.  THE MODELS ARE QUITE DIVERGENT ON THEIR SOLUTIONS YET BUT THE
ONLY THING THEY AGREE ON IS A SLOWER MOVEMENT OF THE SYSTEM.
FRONTAL POSITION IS STILL UNCLEAR AND AN IMPORTANT PLAYER IN
DETERMINING THE SEVERE POTENTIAL.  AT THIS POINT I AM NOT WILLING TO
CHANGE THE CURRENT HWO PRODUCT HOWEVER...THE SLOWER ONSET AND
MOVEMENT OF THE LOW PLACES THE WARM SECTOR SOMEWHERE INTO SOUTHEAST
IOWA AT AN UNFAVORABLE TIME CLIMATOLOGICALLY FOR A WIDESPREAD SEVERE
EVENT IF AT ALL.  THE SYSTEM IS RATHER DYNAMIC THOUGH SO I HESITATE
TO RULE OUT A FEW SEVERE STORMS.  AS FOR THE MODELS...THE EURO WANTS
TO STACK THE SURFACE AND UPPER LOW THUS BEING THE SLOWER SOLUTION
WHILE THE GFS IS JUST SLIGHTLY OUT OF PHASE AND A LITTLE SLOWER.  BY
00Z FRIDAY THE GFS HAS THE SURFACE LOW IN NE KS WHILE THE EURO HAS
IT OVER NCEN KS BUT BOTH PLACE THE WARM FRONT IN NORTHERN MO.
DECENT OVER RUNNING SITUATION SHOULD BRING HEAVIER RAIN TO SOUTHERN
IOWA AGAIN AND PROXIMITY TO THE FRONT HAS KEPT A THUNDER MENTION I
IN THE FORECAST.  BOTH MODELS LIFT THE UPPER LOW NORTHEAST ACROSS
IOWA THURSDAY NIGHT INTO FRIDAY.  HERE IS WHERE WE REALLY DIVERGE AS
THE EURO HAS A STACKED LOW OVER CENTRAL IOWA WHILE THE GFS LIFTS THE
SYSTEM INTO MN/WI BY THIS TIME.  THE DRY SLOT WORKS ITS WAY INTO
WESTERN ILLINOIS THUS TAKING THE SEVERE THREAT INTO THAT AREA BUT A
FAIR AMOUNT OF COLD AIR WILL BECOME ENTRAINED INTO THIS SYSTEM LATE
FRIDAY AND WE COULD SEE RAIN AND ISOLATED THUNDER SE WITH SNOW OVER
THE NW.  I AM NOT READY TO MENTION ACCUMULATING SNOW AT THIS POINT
WITH SUCH DIVERGENT FEATURES IN THE MODELS BUT IT WILL DEFINITELY BE
AN INTERESTING END OF THE WEEK.  WRAP AROUND PRECIP STILL IN STORE
FOR THE START OF THE WEEKEND AS THE LOW IS SLOW TO MOVE OUT.

FOR THE REMAINDER OF THE EXTENDED...SPRING RETURNS.  THE START OF
NEXT WEEK LOOKS DRY WITH TEMPS WARMING TO SEASONAL NORMALS.

.AVIATION...09/00Z
SYSTEM CONTINUES TO PULL OUT THIS EVENING. IN ITS WAKE SOME MVFR ST
HAS DEVELOPED THOUGH A WEAK RIDGING CONTINUES TO ERODE THE CLOUD
FIELD OVER WESTERN IA ATTM. WILL MAINTAIN MVFR ST FOR 6 TO 9 HOURS
OF THE TAF PERIOD WITH CIGS LIFTING TOWARD 12Z MOST AREAS. SOME
3-5SM BR POSSIBLE TOWARD 09-13Z...ESPECIALLY EAST/NORTH SECTIONS
WHERE MORE RAIN FELL TUESDAY. WITH LIGHT WINDS OVN...WILL WATCH
RADIATION FOG TRENDS CLOSELY. WED SHOULD GENERALLY BE VFR CONDITIONS
AS DIVERGENT FLOW AT SFC WITH RIDGE IN PLACE. NEXT SYSTEM TO ARRIVE
LATE WED NIGHT/THURS MORNING AS ACTIVE WX AND MARGINAL/POOR
CONDITIONS RETURN./REV
