AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE DES MOINES IA
645 PM CDT SUN APR 13 2008

...UPDATED AVIATION DISCUSSION...

.DISCUSSION...
DRY AIR IS CONTINUING TO PUSH INTO NW IOWA THIS AFTERNOON AND ERODE
THE STRATOCU. A BRISK NORTHERLY WIND WILL DIE DOWN QUICKLY THIS
EVENING AS THE SURFACE RIDGE SAGS INTO WESTERN IOWA. THE LIGHT WIND
AND CLEAR SKY WILL ALLOW TEMPERATURES TO DROP OFF QUICKLY AND SETTLE
IN THE 20S OVERNIGHT. THE RIDGE WILL SLIDE EAST MONDAY WITH WEAK
RETURN FLOW BECOMING ESTABLISHED AND AFTERNOON HIGHS MAINLY IN THE
50S. BY MONDAY NIGHT...AN EXTENDED PERIOD OF STRONG SOUTHERLY FLOW
WILL BEGIN. THE NAM/GFS ARE BOTH PROJECTING A 17MB PRESSURE GRADIENT
ACROSS IOWA ON TUESDAY. FORECAST SOUNDINGS INDICATE AROUND 40KTS OF
WIND AT THE TOP OF THE MIXED LAYER TUESDAY AFTERNOON...ESPECIALLY
OVER THE NW HALF OF THE CWA. WIND ADVISORIES ARE RELATIVELY RARE
WITH A SOUTHERLY WIND...BUT THIS MAY BE AN EXCEPTION...WITH
SUSTAINED SPEEDS OF 30 MPH OR GUSTS OVER 45 MPH AT TIMES. RECENT
RAINS SHOULD TEMPER TUESDAY/S WARMUP SOMEWHAT...BUT WE CAN STILL
EXPECT HIGHS IN THE UPPER 60S TO LOWER 70S.

THE NEXT SYSTEM WILL PUSH INTO IOWA WEDNESDAY AND WEDNESDAY NIGHT
AND MAY PAY AN EXTENDED VISIT TO THE REGION. MODEL GUIDANCE
CONTINUES TO BE PROBLEMATIC. WILL FOLLOW THE HPC LEAD AND FAVOR THE
GFS WHICH IS MORE PROGRESSIVE WITH THE UPPER LOW. REGARDLESS...WE
COULD STILL BE IN FOR SEVERAL SHOTS OF SIGNIFICANT RAINFALL BEFORE
THE STALLED BOUNDARY FINALLY PUSHES EAST OVER THE WEEKEND.

&&

AVIATION...14/00Z
VFR CONDITIONS WILL PREVAIL TONIGHT AND MONDAY. SURFACE HIGH
PRESSURE IS BUILDING OVER THE HIGH PLAINS...AND WILL MOVE INTO
NORTHWESTERN IOWA OVERNIGHT. NORTH WINDS WILL SLACKEN THIS EVENING
AND BECOME LIGHT ACROSS THE AREA BEFORE MIDNIGHT. WIND DIRECTION
WILL BE VARIABLE THROUGH THE EARLY MORNING...ESPECIALLY ACROSS THE
NORTH...BEFORE COMING AROUND TO SOUTH SOUTHWESTERLY MONDAY AFTERNOON
AS THE HIGH PRESSURE BEGINS TO PULL AWAY TO THE EAST. NO
PRECIPITATION IS EXPECTED TONIGHT OR TOMORROW.
