AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DES MOINES IA
720 AM CDT SAT APR 19 2008

...UPDATED FOR AVIATION DISCUSSION...

.SHORT TERM...TODAY
MAIN SHORT TERM ISSUE WILL BE DEALING WITH THE DEPARTURE OF THE
UPPER LOW. LOW CLOUDS AND SCATTERED SHOWERS EXPECTED TO PERSIST THIS
MORNING AS CYCLONIC FLOW PERSISTS ON BACKSIDE OF LOW. HOWEVER...THE
LOW WL DRIFT GRADUALLY EAST WITH ITS INFLUENCE DIMINISHING THROUGH
THE DAY. HAVE CUT BACK ON POPS DURING THE AFTERNOON AND STARTED SOME
CLEARING IN THE FAR WEST BY LATE IN THE AFTERNOON. HAVE UNDERCUT
GUIDANCE TEMPS GIVEN THE EXTENSIVE CLOUD COVER DURING THE DAY ALONG
WITH SOME LIGHT PCPN THIS MORNING.

.LONG TERM...TONIGHT THROUGH WEDNESDAY
ONCE LOW PRESSURE SYSTEM EXITS THIS EVENING RIDGING WILL BUILD
OVERHEAD...RESULTING IN A DROP IN WIND SPEEDS ALONG WITH GRADUAL
CLEARING. THIS WILL BRING FOG TO THE AREA IN THE EARLY MORNING HOURS
SUNDAY. COVERAGE DIFFICULT TO PIN DOWN AS THERE IS STILL SOME
UNCERTAINTY IN FORECAST OF LOW LEVEL CLOUDINESS...HOWEVER AREAS OF
FOG SEEM LIKELY BY THE PRE-DAWN HOURS...DISSIPATING A COUPLE HOURS
AFTER SUNRISE.

NEXT MID-LEVEL SYSTEM WILL BARREL NORTHWARD FROM MONTANA INTO CANADA
EARLY NEXT WEEK. WEATHER IN OUR AREA WILL REMAIN QUIET UNTIL
MONDAY...WHEN SURFACE TROUGH APPROACHES FROM THE WEST. WITH
SOUTHWESTERLY FLOW AT 500 MB SURFACE IMPULSES WILL SPEED
NORTHEASTWARD THROUGH THE REGION...WITH MONDAY NIGHT AND EARLY
TUESDAY BEING THE MOST LIKELY TIME FOR IOWA TO BE AFFECTED.
HOWEVER...THE PRECISE LOCATION/TRACK OF ANY SUCH SURFACE LOW WILL
HAVE A SIGNIFICANT IMPACT ON RESULTING WEATHER. IN ANY EVENT SOME
FORM OF RAIN IS LIKELY MONDAY NIGHT...AND HAVE CONTINUED TO TREND
POPS UPWARD. SOME SEVERE WEATHER IS POSSIBLE WITH THIS SYSTEM...BUT
THIS WILL DEPEND ON EXACTLY WHEN/WHERE SURFACE LOW PRESSURE
DEVELOPS. RAIN SHOULD END BY LATE TUESDAY AS THE TROUGH MOVES EAST
OF THE AREA...WITH QUIET WEATHER THEREAFTER THROUGH WEDNESDAY NIGHT.

&&

.HYDROLOGY...
FLOOD WATCH MARGINAL BUT WITH PRECIP REDEVELOPING OVER SRN IA AND
STILL LIFTING THROUGH ALO CANNOT SEE ANY REASON TO CANCEL
PREMATURELY...ESPECIALLY WITH MINOR FLOODING ALREADY IN PROGRESS.
WILL LET HEADLINE RIDE TIL NATURAL EXPIRATION OR POSSIBLY EXTENSION
IF EVE SHIFT SEES THE NEED AND SRN IA PCPN INTENSIFIES.  FORECAST
RAINFALL AMOUNTS WERE RIGHT ON TARGET WITH MANY LOCATIONS SEEING 1-2
INCHES IN 24 HOUR PERIOD ENDING AT 20Z.  TWO TO NEARLY 2.50 INCHES
HAS FALLEN IN SOME PORTIONS OF SOUTHEAST AND E CENTRAL FORECAST AREA.

&&

.AVIATION...19/12Z
MVFR TO IFR CONDITIONS REMAIN WIDESPREAD THIS MORNING AS UPR LOW
SLOWLY PULLS AWAY FROM IA.  WL SEE VSBYS IMPROVE TODAY WITH CEILINGS
BECOMING MVFR.  EXPECT CLEARING IN WESTERN IA BY THIS AFTERNOON
SPREADING EAST THIS EVENING.  SFC RIDGE WL BE OVER IA TONIGHT WITH
LIGHT WINDS AND MOIST ATMOSPHERE.  EXPECT FOG TO DEVELOP ALONG WITH
