AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE DES MOINES IA
620 PM CDT THU APR 17 2008

UPDATED AVIATION DISCUSSION

.SYNOPSIS...
LG WV TROUGH ENTERING HIGH PLAINS THIS AFTERNOON WITH RIGHT ENTRANCE
REGION OF NRN GREAT LAKES JET AIDING UVM OVER IA.  PCPN WHICH WAS
ASSOCIATED WITH DEF ZN AND SHEARED VORT MAX FROM BASE OF TROUGH INTO
PLAINS IS BECOMING ROOTED LOWER AND CLOSER TO SFC FRONTAL BOUNDARY.
CONVECTION APPEARS TO BE ORIENTED MORE WITH H85/H7 THETA-E ADVECTION
AND FRONTOGENETICAL RESPONSE AS 100-500 MUCAPES SURGE INTO SERN HALF
OF IA.  EFFECTIVE SHEAR/SRH HAS INCREASED ENOUGH THAT A FEW CELLS
ARE WEAKLY ROTATING AND PRODUCING HAIL.  19Z SFC ANLYS SHOWS STRONG
BAROCLINIC ZONE OVER FAR SERN IA WITH 30F TEMP CHANGE FROM NW-SE.

&&

.SHORT TERM...TONIGHT THROUGH SUN
SFC LOW OVER NRN OK AND ATTENDANT FRONTAL BOUNDARY WHICH EXTENDS
INTO SERN IA WILL BE THE MAIN PLAYER IN THE WEATHER FOR TONIGHT.
WEAK INSTABILITY BUT DECENT FORCING SOUTHEAST OF THE BOUNDARY IS
PROVIDING ENOUGH FOR THUNDERSTORM DEVELOPMENT JUST NORTH OF THE
BOUNDARY.  THE SYSTEM SHOULD HOWEVER BE A PROLIFIC RAIN PRODUCER AS
SEVERAL WAVES TRAVEL UP THE FRONTAL BOUNDARY AND ENHANCE RAINFALL.
NO CHANGES TO THE GOING FLOOD WATCH THOUGH QPF VALUES ARE NOT AS
HIGH AS PREVIOUSLY FORECAST.  CONCERN THAT A DRY SLOT MOVES INTO THE
CWA OVERNIGHT AND GIVES US A PERIOD OF LIGHT TO NO RAINFALL.  THIS
WOULD BE GOOD FOR THE FLOODING POTENTIAL AS IT WOULD REDUCE THE
THREAT BUT THE GENERAL FEELING IS THAT ENOUGH RAIN WILL FALL OVER
THE PRIME AREA FOR MINOR FLOODING BEFORE DAYBREAK.

MUCH LIKE YESTERDAY...WILL LEAN HEAVILY ON GFS/NAM 295-305K ISENT
LAYER FOR PRECIP DEPICTION.  PRIMARY AXIS OF MOISTURE TRANSPORT AND
LOW PRESSURE DEFICITS SHOULD BE FOCUSED INTO MS RIVER FRI WITH WRAP
AROUND FETCH INTO NRN IA.  DRY SLOT INFLUENCES COULD CERTAINLY BE IN
PLACE SRN SECTIONS SO HAVE CATEGORICAL WORDING NORTH DOWN TO CHANCES
SOUTH BY AFTERNOON.  MOISTURE TRANSPORT WEAKENS AND P DEFS
DECREASE BUT STILL APPEAR SUFFICIENT FOR LIGHT RAIN FRI NIGHT AND
SAT MORNING BEFORE ENDING EAST.

FAIR WEATHER IN PLACE FOR REMAINDER OF WEEKEND WITH MODERATING
SEASONAL TEMPERATURES AS SHORT WV RIDGE ENTERS MO VALLEY.  HAVE
BACKED OFF FURTHER ON TEMPS FRI WITH SIMILAR CLOUDY/RAIN COOLED
SCENARIO AS TODAY...AT OR BELOW COOLEST GUIDANCE.  DECENT GRADIENT
SHOULD BE IN PLACE SAT AS WELL...SW TO NE.

.LONG TERM...SUN NIGHT THROUGH THU
MAIN CONCERN REMAINS LARGE LOW ALONG US/CANADIAN BORDER EARLY IN THE
PERIOD AND ASSOCIATED FROPA.  RECENT MODEL RUNS HAVE BEEN LESS
BULLISH ON PRECIP AHEAD AND WITH CFP.  MARGINAL DEEP MOISTURE...WARM
LAYER ALOFT AND FORCING FARTHER NORTH ARE DIMINISHING CHANCES OF
ELEVATED CONVECTION.  WARM LAYER ALSO SEEMS TO INCREASE CIN HOLDING
BACK SFC BASED THREAT WITH FRONT.  HAVE REDUCED POPS SOMEWHAT BUT
STILL IN CHANCE CATEGORY...MAINLY MONDAY WITH FROPA...AND AGAIN TUE
JUST BEHIND.

&&

.HYDROLOGY...
WILL LEAVE WATCH IN PLACE WITH NO CHANGES.  HEADLINE MAY BE
MARGINAL...BUT WITH CONVECTIVE BAND SETUP AND LIKELY CONTINUING INTO
THE EVENING...SEEMS FOOLISH TO CANCEL OR ADJUST AT THIS POINT.
STORM TOTAL PRECIP IS NOW DOWN SLIGHTLY TO 1-2 INCHES WITH ISOLATED
HIGHER AMOUNTS POSSIBLE.  HEAVIEST BAND IS FROM SE INTO ERN IA WHERE
IEM/IOWA DAILY EROSION PROJECT STILL HAS HIGHEST SOIL MOISTURE SO
THAT IS ANOTHER REASON TO LEAVE STATUS QUO.

&&

.AVIATION...18/00Z
TAF SITES WILL BE MIRED IN IFR TO MVFR CONDITIONS WITH A NEARLY
CONTINUOUS THREAT OF SHOWERS. SHORT TERM HIGH CONFIDENCE OF AT LEAST
VCTS AT KDSM...KALO AND KOTM. BEYOND THE NEXT 3 TO 6
HOURS...CONFIDENCE IN ANY GIVEN TIME YIELDING THUNDER NOT VERY
GOOD...SO HANDLED WITH A CB MENTION. MAY HAVE IMPROVING CONDITIONS
FROM THE SW AFT 21Z...BUT DID NOT ILLUSTRATE THAT IN TAFS DUE TO LOW
CONFIDENCE.

&&

.DMX WATCHES/WARNINGS/ADVISORIES...FLOOD WATCH GENERALLY ALONG AND
SE OF AUDUBON-BOONE-BUTLER COUNTIES TONIGHT AND FRIDAY.
