AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DES MOINES IA
540 AM CST SUN JAN 24 2010

...UPDATED FOR 12Z AVIATION DISCUSSION...

.SHORT TERM /TODAY/...
UPPER SYSTEM WILL PASS THROUGH EASTERN IOWA THIS MORNING AS IT LIFT
NORTHWARD INTO WISCONSIN.  CURRENTLY...PCPN HAS INCREASED ON
BACKSIDE OF SFC LOW WHERE DEFORMATION IS OCCURRING IN THE MID
LEVELS.  PCPN HAS REMAINED RAIN...BUT DYNAMIC COOLING HAS PULLED
TEMPERATURES TO NEAR FREEZING AND MAY BEGIN TO MIX WITH SNOW IN THE
NEXT HOUR OR TWO.  HAVE UPDATED THE GRIDS FOR THIS POTENTIAL AND
HAVE GONE WITH RAIN/SNOW MIX IN THE FAR EAST THROUGH 15Z THIS
MORNING.  THEREAFTER...SYSTEM SHOULD PULL TO THE NORTHEAST WITH PCPN
ENDING.  FARTHER WEST...SUBSIDENCE AND DRIER AIR WILL LEAD TO SOME
CLEARING WEST OF INTERSTATE 35 THIS MORNING WITH SOME SUNSHINE
EXPECTED FOR THE FIRST TIME IN ABOUT A WEEK.  HOWEVER...ANY SUN WILL
BE ACCOMPANIED BY BRISK NORTHWEST WINDS AS STRONG CAA MOVES INTO THE
STATE.  TEMPS WILL BE HARD PRESSED TO CLIMB MUCH TODAY AS 850MB
TEMPS FALL BY 5-10C ACRS THE STATE.  THE PARTIAL CLEARING IN THE
WEST WILL BE QUICKLY REPLACED BY STATUS BY AFTERNOON WITH AN
INCREASING THREAT OF SOME SNOW SHOWERS AS UPPER LOW DIVES SOUTHEAST
FROM THE DAKOTAS.

.LONG TERM /TONIGHT THROUGH SATURDAY/...
SECONDARY SYSTEM TO ARRIVE TONIGHT ACROSS THE REGION AS NO MAJOR
CHANGES TO PREVIOUS THINKING. WITH 2 SHORT WAVES EMBEDDED IN THE
FLOW UPSTREAM OF IOWA...WE WILL SEE PERIODS OF LIGHT SNOW TONIGHT
AND MONDAY...EXTENDING INTO EARLY TUESDAY EAST. QPF AMOUNTS ARE
RATHER LIGHT AND WITH LESS ABOUT A TENTH OF AN INCH OF TOTAL QPF
EXPECTED THROUGH THE ENTIRE EVENT...EVEN HIGH SNOW RATIOS WILL YIELD
BETWEEN 1 AND 2 INCHES AT MOST OF NEW SNOWFALL IN 36 HOURS. THE
LARGER ISSUE FOR TONIGHT AND MONDAY WILL BE THE INCREASING WIND
FIELDS ACROSS THE AREA. STEEPENING LAPSE RATES AND A GROWING
BOUNDARY LAYER ON MONDAY WILL ALLOW FOR DEEPER MIXING FROM 15Z
THROUGH 00Z TUESDAY. CURRENT SOUNDINGS SUGGEST ADVISORY CRITERIA
WINDS BEGINNING ABOUT 12Z TO 15Z MONDAY MORNING AND CONTINUING TO
ABOUT 03Z TUESDAY. LOOKING AT THE SOUNDINGS SUGGESTS NORTHERN
SECTIONS MAY SEE WINDS GUSTING TO NEAR 50 MPH AT TIMES WITH 45 MPH
GUSTS COMMON ACROSS MUCH OF THE REST OF THE FORECAST AREA. WITH
EXPECTED PERIODS OF LIGHT SNOW...BLUSTERY...WINTRY CONDITIONS WILL
RETURN TO THE REGION. MONDAY STILL SHOWS FALLING TEMPS FOR THE DAY
TIME HOURS ONCE THE MIXING BEGINS IN EARNEST. THE REMAINDER OF THE
WEEK IS SEES COLDER TEMPS AS PER PREVIOUS PACKAGES. THE GFS IS
TRENDING AWAY FROM THE OTHER MED RANGE MODELS WITH A MIDWEEK STORM
DROPPING SOME LIGHT SNOW OVER THE AREA ON WED...WHILE THE GEM AND
EURO KEEP THE SYSTEM MAINLY SOUTH OF US AND SLOWER. HAVE INTRODUCED
A SLIGHT CHANCE OF SNOW WED NIGHT ACROSS THE SOUTH...OTHERWISE HAVE
KEPT THE MIDWEEK DRY FOR NOW. TOWARD WEEKS END ANOTHER ATTIC
BOUNDARY LOOKS TO BE DROPPING INTO THE GREAT LAKES AND PLAINS. BOTH
THE GEM AND EURO KEEP THE COLD AIR NEARER THE POLAR VORTEX OVER
QUEBEC WHILE THE GFS IS MUCH FARTHER WEST WITH THE LOW AND
CONSEQUENTLY DRIVES THE COLD AIR INTO CENTRAL IOWA. ATTM...FEEL THE
GFS IS OVERDONE AND TOO FAR WEST...AND HAVE LESS CONFIDENCE IN IT
FOR NOW GIVEN LACK OF CONSENSUS WITH THE PREVIOUS SYSTEM ONLY ONE
DAY PRIOR. THOUGH LATE WEEK AND EARLY  WEEKEND IS LOOKING COLDER
BASED ON ANY MODEL...THE LESS COLD SOLNS OF THE GEM AND EURO LOOK
MORE APPROPRIATE FOR NOW.

.AVIATION...
24/12Z...SFC LOW WILL CONTINUE TO PULL INTO WISCONSIN TODAY WITH
TIGHTENING PRESSURE GRADIENT ACRS IA.  SFC WINDS FROM THE NORTHWEST
WILL BE MODERATE TO STRONG TODAY AND TONIGHT AS GRADIENT REMAINS
FIRM. WL SEE SOME VFR CIGS ACRS WESTERN IA THIS MORNING AS LOW
STATUS EXITS TO THE EAST.  HOWEVER...INCREASING COLD ADVECTION AS
SECONDARY UPPER SYSTEM HEADS TOWARDS WL LEAD TO STRATUS FILLING BACK
IN ACRS THE ENTIRE STATE DURING THE AFTERNOON.  WIDESPREAD MVFR CIGS
ARE THEN FORECAST OVERNIGHT ALONG WITH SCATTERED SNOW SHOWERS ACRS
IA.   VSBYS WL LIKELY BE VFR EXCEPT AROUND SNOW SHOWERS AND AREAS OF
BLOWING SNOW.

.HYDROLOGY...
THE LACK OF EXPECTED QPF HAS LESSENED THE THREAT OF FLOODING FOR
MOST OF THE AREA...THOUGH A FEW AREAS AS OF LATE SATURDAY NIGHT HAVE
REPORTED MINOR FLOODING DUE TO PONDING AND MELTING OF SNOW. RUNOFF
FROM THE CRUSTED SNOW FIELDS WILL STILL CAUSE WITHIN BANK RISES IN
RIVERS AND STREAMS AND A FEW STREAMS MAY GO INTO FLOOD. LOCALIZED
FLOODING IS ALSO STILL A POSSIBILITY. THOUGH THE RAIN HAS
ENDED...THERE IS STILL MELTING OCCURRING EVEN LATE SATURDAY NIGHT AS
TEMPERATURES REMAIN ABOVE FREEZING OVER ALL OF CENTRAL IOWA.
