AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DES MOINES IA
1232 PM CDT THU MAR 27 2014

.SHORT TERM /TODAY/...
ISSUED AT 335 AM CDT THU MAR 27 2014

SOUTH WINDS CONTINUE TO BE RATHER BRISK EARLY IN THE PERIOD AS
GRADIENT WINDS THROUGH TODAY AHEAD OF LOW AND COLD FRONT EXPECTED
TO MOVE ACROSS THE REGION THIS AFTERNOON. FOR NOW...HAVE CUT BACK
ON POP OVERNIGHT AND INTO MORNING HOURS AS MAIN AREA OF WARM AIR
ADVECTION GENERATED RAIN IS MOVING OFF TO THE EAST OVER EASTERN
IOWA AND ILLINOIS AT THIS TIME. SFC ANALYSIS CONTINUES TO SHOW
MAIN WAVE BACK IN SOUTH CENTRAL NE AT 0700UTC WITH STRONG
SOUTHERLY FLOW AHEAD OF THE SYSTEM. CONVECTION AND SHOWERS WILL
CONTINUE TO DEVELOP ALONG THE FRONT AND NEAR THE LOW TO OUR WEST
EARLY IN THE PERIOD. OVER CENTRAL IA AN INCREASING AREA OF LIGHT
DRIZZLE AND SHOWERS IS DEVELOPING AND SPREADING NORTH AS MOISTURE
RETURNS NOW. WITH THE LOW DRIVING INTO WESTERN IOWA THIS MORNING
INSTABILITY WILL INCREASE ACROSS THE WEST WITH ELEVATED CONVECTION
MOVING INTO SOUTHERN AND WESTERN SECTIONS BETWEEN 13 AND 17Z.
ACROSS THE SOUTH WARM AIR SHOULD STREAM ACROSS THE AREA AND ALLOW
FOR HIGHS TO REACH THE THE MID TO UPPER 40S NORTH THROUGH US20
WHILE ALONG AND SOUTH OF I80 HIGHS WILL REACH THE MID TO UPPER 50S
BEFORE THE COLD FRONT REACHES OUR AREA BY 18Z AND TEMPS FALL INTO
THE AFTERNOON. BY 17Z THROUGH 23Z THERE WILL BE A CHANCE FOR SCT
THUNDER ACROSS THE SOUTH HALF OF THE AREA WITH MLCAPE BETWEEN 100
AND 350 ACROSS THE AREA. WIND FIELDS REMAIN RATHER IMPRESSIVE WITH
COLUMN WINDS 45 TO 65KT FROM H850 UP TO H300 BY 21Z OVER FAR
SOUTHERN AND SOUTHEAST IOWA. THOUGH GENERAL THUNDER WILL BE THE
MAIN CONCERN TODAY...THE FAR SOUTHEAST MAY SEE ENOUGH SHEAR TO
PRODUCE A FEW SEVERE STORMS BETWEEN 19-23Z AS THE FRONT PUSHES
THROUGH THE REGION. MAIN THREATS WOULD BE WIND AND HAIL...WITH
WIND LEADING THE WAY. BOTH THE GEM/ EURO AND TO A LESSER EXTENT
THE GFS SUGGEST A DUAL WAVE ROTATING THROUGH THE AREA TODAY. THIS
SHOULD ENHANCE A DEFORMATION AXIS ON THE BACK SIDE OF THE STORM
AND KEEP RAIN AND R/S MIX GOING THROUGH THE AFTERNOON. WITH THE
SLIGHTLY WARMER AIR EXPECTED IN THE SYSTEM TODAY...HAVE TRIMMED
BACK THE CHANGEOVER TO R/S NORTHWEST AND STILL EXPECT TO SEE NO
ACCUMULATION OF SNOW THROUGH 00Z TODAY OVER THE WEST/NORTHWEST
DESPITE THE COOLER AIR GETTING INTO THE SYSTEM. WINDS SHOULD
REMAIN RATHER BRISK THROUGH THE DAY UNTIL THE LOW/FRONT ARRIVE
THEN LESSEN THROUGH THE EARLY AFTERNOON AND THEN INCREASE FROM THE
NORTHWEST AS THE LOW PASSES EAST BY 00Z.

.LONG TERM /TONIGHT THROUGH WEDNESDAY/...
ISSUED AT 335 AM CDT THU MAR 27 2014

GENERALLY QUIET WEATHER UNTIL EARLY NEXT WEEK. THE MAIN ISSUE WAS
FOCUSED ON A SERIES OF LOW PRESSURE SYSTEMS STARTING MONDAY AND
WITH TEMPERATURES OVER THE WEEKEND. GFS/ECMWF ARE IN SOMEWHAT
BETTER AGREEMENT WITH SYSTEM MONDAY...WITH THE GFS SLIGHTLY
FURTHER SOUTH THAN THE ECMWF. THIS WAS A COMPLETE OPPOSITE FROM
THE 26.00Z INITIALIZATIONS AND IT SEEMS THE MODELS ARE PLAYING
CATCH-UP WITH EACH OTHER. REGARDLESS...THEY DO AGREE ON TIMING AND
USED A BLEND FOR EARLY NEXT WEEK.

TONIGHT THROUGH SUNDAY...PRECIPITATION LOOKS TO QUICKLY MOVE EAST
OF THE FORECAST AREA THIS EVENING BUT MAY SEE A SHORT SWITCH OVER
TO SNOW ACROSS THE FAR NORTH. HAVE AN INCH OR LESS GOING NEAR THE
MINNESOTA BORDER ATTM BUT FORCING AND DEPTH OF MOISTURE IS
LIMITED WITH THE TIMING OF THE COLDER AIR...SO HAVE LOW
CONFIDENCE WITH ANY HIGHER AMOUNTS. THE CAA PERSISTS INTO EARLY
FRIDAY BEFORE DIMINISHING AS THE SURFACE HIGH PRESSURE BUILDS
INTO THE REGION.

A WEAK 500MB SHORTWAVE MOVES ACROSS IOWA/MISSOURI FRIDAY NIGHT
AND MAINLY BRINGS CLOUD COVER ACROSS THE STATE. LIMITED FORCING
WITH THIS SYSTEM EVEN THOUGH SOUNDINGS SUGGEST DRIZZLE FOR A SHORT
TIME FRAME LATE FRIDAY NIGHT...LEFT FORECAST DRY ATTM.

WAA DEVELOPS SATURDAY AFTERNOON AND CONTINUES INTO SUNDAY. THE
BETTER MIXING DAY IS ON SUNDAY AND GFS BUFR SOUNDINGS SHOW GOOD
DRY ADIABATIC MIXING TO AROUND 850MB. NOT CONFIDENT IT WILL MIX
THAT DEEP...BUT CONFIDENT ENOUGH TO GO A COUPLE DEGREES ABOVE
GUIDANCE FOR MAX TEMPS ON SUNDAY. DEW POINTS VERY DRY AS WELL AS
THEY GENERALLY RANGE IN THE MIDDLE TO UPPER 30S. ALSO...WITH 40
KNOT WINDS AT THE MIXED LAYER...INCREASED WINDS SLIGHTLY DURING
SUNDAY AFTERNOON BUT REMAIN JUST BELOW ADVISORY CRITERIA ATTM.

MONDAY THROUGH WEDNESDAY...SURFACE LOW MOVES ACROSS IOWA/SOUTHERN
MINNESOTA DURING THE DAY MONDAY AND EXITS THE STATE MONDAY EVENING.
MAINLY LOOKING AT RAIN THROUGH MUCH OF THE EVENT...WITH THE COLDER
TEMPERATURES WRAPPING AROUND LOW BEGINNING AROUND 00Z TUESDAY. THE
DEEPER MOISTURE AND BETTER FORCING MONDAY NIGHT REMAINS NORTH OF THE
FORECAST AREA...SO NOT ANTICIPATING MUCH OF THE WAY SNOW AMOUNTS
ATTM. ANOTHER SYSTEM MOVES ACROSS THE SOUTHERN PLAINS INTO NORTHER
MISSOURI ON WEDNESDAY AND LOOKS TO BE ANOTHER RAIN AND POSSIBLY SNOW
PRODUCER DEPENDING ON HOW FAR SOUTH THE LOW TRACKS.
REGARDLESS...NEXT WEEK LOOKS TO BEGIN AN ACTIVE WEATHER PATTERN
ACROSS THE REGION.

&&

.AVIATION...27/18Z
ISSUED AT 1232 PM CDT THU MAR 27 2014

SURFACE LOW PRESSURE WILL LIFT NORTHEAST ACROSS SOUTHERN THEN
EASTERN IOWA.  LIFR CONDITIONS ARE NOT EXPECTED TO IMPROVE MUCH
THROUGH 09Z UNTIL AFTER THE LOW PASSES.  WINDS WILL INCREASE THIS
AFTN AND EVENING AS THE LOW PASSES AND WINDS SWITCH AROUND TO A
NORTHERLY DIRECTION.  INSTABILITY ACROSS FAR SOUTHERN IOWA TIED TO A
FRONTAL BOUNDARY WILL PRODUCE ISOLATED TO SCATTERED THUNDERSTORMS
ESPECIALLY BETWEEN 21Z-00Z.  AN ISOLATED STORM COULD PRODUCE STRONG
WIND OR LARGE HAIL...MAINLY AFFECTING KOTM THROUGH THIS TIME.
