922 PM CDT FRI APR 10 2009

.UPDATE...
/920 PM CDT FRI APR 10 2009/
BACK EDGE OF LOW CLOUDS TAKING ITS SWEET TIME MOVING E THIS
EVENING. EXTRAPOLATION OF THIS EDGE HAS IT NR A KVIH...KTAZ LN BY
06Z...AND MOVING THROUGH STL CITY 08-09Z. TWEEKED SKY GRIDS TOWARD THIS
TREND ERYR THIS EVENING...AND HAVE FINE TUNED THE TREND FOR THIS
UPDATE. IN SPITE OF THE SLOWER MOVEMENT...THERE SHOULD STILL BE
PLENTY OF TIME FOR GOOD RADITIONAL COOLING OVER CENTRAL AND PARTS
OF E MO DURING THE PREDAWN HOURS...ALLOWING TEMPS TO DROP INTO THE
LM 30S. THREAT OF FROST IN THESE AREAS STILL LOOKS GOOD....SO NO
CHANGES PLANNED TO HEADLINE ATTM.

.DISCUSSION...
/335 PM CDT FRI APR 10 2009/
LOW PRESSURE OVER WESTERN KENTUCKY WILL CONTINUE MOVING EAST AWAY
FROM THE BI-STATE REGION THIS EVENING.  RAIN HAS COME TO AN END OVER
THE MAJORITY OF THE AREA...AND REMAINING LIGHT TO MODERATE RAIN OVER
SOUTHERN ILLINOIS SHOULD BE ENDING BY LATE THIS AFTERNOON.  DONT
EXPECT ANY MEASURABLE RAINFALL AFTER 00Z TONIGHT...SO HAVE LEFT
FORECAST DRY FOR THIS EVENING.  CLOUDS WILL BE CLEARING OUT FROM
WEST TO EAST AS THE SYSTEM PULLS AWAY.  DRIER AIR ACROSS IOWA SHOULD
FILTER DOWN INTO THE REGION AND WINDS WILL BE CALMING DOWN ALLOWING
TEMPS TO COOL ENOUGH FOR FROST ACROSS MUCH OF CENTRAL MISSOURI.  DO
NOT PLAN ON ANY CHANGES TO FROST ADVISORY AT THIS TIME.

SATURDAY STILL LOOKS LIKE THE CHOICE DAY OF THE WEEKEND WITH HIGH
PRESSURE FIRMLY IN PLACE OVER THE REGION.  TEMPS ARE A LITTLE TRICKY
THO AS MODELS ARE INDICATING A WELL MIXED ATMOSPHERE WHICH WOULD
TEND TO HELP WARMING...BUT LOW LEVEL EASTERLY FLOW IS NOT TERRIBLY
PROMISING FOR WARMING.  HAVE UNDERCUT MOS JUST SLIGHTLY...ONLY 2-3
DEGREES IN MOST LOCATIONS FOR HIGHS ON SATURDAY.

THE NEXT STORM SYSTEM IN LINE IS ALREADY COMING ON SHORE OVER THE
WEST COAST AND WILL BE MOVING ACROSS THE ROCKIES THROUGH SATURDAY
EMERGING INTO THE GREAT PLAINS EARLY SUNDAY MORNING.  THIS SYSTEM
LOOKS VERY MUCH LIKE TODAYS STORM...A DEEP VERTICALLY STACKED LOW
WHICH WILL LIKELY HIT US WITH ANOTHER INCH OR TWO OF RAIN BEGINNING
LATE SUNDAY AFTERNOON OR SUNDAY EVENING...AND CONTINUING THROUGH
MUCH OF THE DAY MONDAY.  SEVERE WEATHER POTENTIAL WILL DEPEND
GREATLY ON HOW FAR NORTH THE SURFACE LOW TRACKS...BUT CURRENT
INDICATIONS ARE THAT ONLY SOUTHERN PORTIONS OF THE CWFA WILL BE
UNDER A SEVERE WEATHER THREAT.  PROBABLY OF MORE CONCERN WILL BE
POTENTIAL WATER IMPACTS.  WHILE MOST OF THE TRULY HEAVY RAIN WILL
LIKELY BE ACROSS SOUTHERN MISSOURI...ANOTHER 12-18 HOUR STRETCH OF
MODERATE RAIN WITH 1-2 INCH TOTALS COULD CAUSE MORE FLOODING ON SOME
OF OUR SMALLER RIVERS AND STREAMS.

REMAINDER OF THE FORECAST LOOKS LIKE MORE OF THE SAME.  A BREAK IN
THE RAIN TUESDAY INTO WEDNESDAY...THEN THE NEXT SYSTEM PULLS INTO
THE PLAINS AND MIDWEST THURSDAY AND FRIDAY.

.AVIATION...
/616 PM CDT FRI APR 10 2009/
FOR THE 00Z TAFS...CLOUDS WILL CONTINUE TO LIFT AND EXIT THE TAF
SITES THIS EVENING. KUIN WILL BE THE FIRST TO CLEAR OUT WHILE KCOU
WILL SCATTER OUT BY 02Z. AS FOR KSUS/KSTL...WILL SEE MVFR CIGS FOR A
FEW MORE HOURS...THEN SCATTER OUT AFTER 03Z. AS FOR THE WINDS...THE
GUSTY NORTH WINDS HAVE DIMINISHED AND WILL CONTINUE TO RELAX EVEN
MORE. SO THIS IN TANDEM WITH CLEAR SKIES AND THE RECENT RAINFALL MAY
RESULT IN SOME LIGHT EARLY MORNING RADIATIONAL FOG...ESPECIALLY AT
KCOU...KSUS AND KSTL. DURING THE DAY TOMORROW SHOULD SEE WINDS
BECOME NORTHEASTERLY THEN EASTERLY.
