AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE DES MOINES IA
1245 AM CDT SUN APR 8 2012

...UPDATED FOR 18Z AVIATION DISCUSSION...

.SHORT TERM /TODAY/...
SEVERAL THINGS TO CONTEND WITH TODAY.  FIRST THE FROST ADVISORY...
CALLED THE SHERIFFS OFFICES IN A COUPLE PLACES IN THE ADVISORY AREA
AND WAS TOLD THAT THERE WAS NO FROST ANYWHERE AND THAT IT WAS VERY
DRY.  WITH DEWPOINTS MANY PLACES IN THE TEENS AND 20S AND NO REPORTS
OF FROST WE WILL BE PULLING THE FROST ADVISORY WITH THE NEW
ISSUANCE.  NEXT...WATER VAPOR SHOWING A VORT MAX PUSHING SOUTHEAST
ACROSS THE NORTHERN HIGH PLAINS AND THIS WILL BRUSH
NORTHERN/NORTHEAST IOWA.  TURNING TO SOUNDINGS...THEY CONTINUE TO BE
EXTREMELY DRY BUT DO SHOW SOME MOISTENING UP ACROSS MCW AND ALO WITH
THE PASSAGE OF THIS FEATURE.  IN ADDITION...TIME HEIGHT CROSS
SECTIONS DO SHOW SOME FORCING THROUGH THE SATURATED LAYER.  I DO
NOT SEE THIS AMOUNTING TO MUCH GIVEN HOW DRY THE AIR IS BUT A BRIEF
SPRINKLE CANNOT BE RULED OUT THIS AFTERNOON.  THERE IS JUST NOT
ENOUGH THERE TO PUT IN THE FORECAST.  WIND IS A CONCERN TODAY WITH
INVERTED V SOUNDINGS PRETTY MUCH EVERYWHERE.  HOWEVER...THE
STRONGEST WINDS REMAIN ABOVE THE MIXED LAYER SO THE WIND WHILE
BREEZY WON/T BE OUT OF CONTROL.  ALSO TO CONSIDER ACROSS THE NORTH
IF THAT VORT MAX PRODUCES SOME CLOUD COVER ACROSS THE
NORTH/NORTHEAST THEN THE MIXING WILL NOT BE AS GOOD AS ADVERTISED
THUS THE WIND WILL NOT BE AS STRONG.  WITH MARGINAL WIND WE DECIDED
TO ONCE AGAIN HIT THE ELEVATED FIRE RISK WORDING IN THE HWO BUT
REFRAIN FROM ISSUING AN RFW.  CONDITIONS LOOK MORE FAVORABLE FOR
MONDAY WHICH WILL BE DISCUSSED BELOW.  AS FOR TEMPS...I NUDGED THEM
HIGHER TODAY BY A COUPLE DEGREES GIVEN THE MIXING AND DRY AIR...THE
SUN SHOULD WARM TEMPS NIGHTLY.

.LONG TERM /TONIGHT THROUGH SATURDAY/...
MAIN QUESTIONS IN THIS PERIOD SPLIT INTO SEASONAL FROST/FREEZE AND
FIRE WEATHER CONCERNS THROUGH MIDWEEK FOLLOWED BY INCREASED PRECIP
POTENTIAL INTO NEXT WEEKEND.  COMPACT SHORT WAVE/PV ANOMALY WILL
DIVE FROM CANADA INTO THE GREAT LAKES TONIGHT AND MONDAY.  ANY
SENSIBLE WEATHER SHOULD REMAIN TO OUR NORTH AND EAST.  THIS FEATURE
WILL BE FOLLOWED BY CONTINUED STRONG NWLY FLOW AND SURFACE HIGH
BUILDING INTO REGION.  HAVE REMOVED FROST WORDING TONIGHT.  MINS
WILL DROP INTO THE LOW/MID 30S NORTH AND WEST BUT WITH DRY AIRMASS
AND WINDS NOT DROPPING OFF SUFFICIENTLY DO NOT FEEL THERE IS MUCH
FROST POTENTIAL.  SIMILAR THINKING REGARDING FROST POTENTIAL MON
NIGHT AS DEWPOINTS DROP EVEN FURTHER BUT PERSISTENT COLD ADVECTION
WILL LEAD TO MINS IN THE UPPER 20S TO LOWER 30S.  FREEZE HEADLINE
WILL LIKELY BE NEEDED IN MANY AREAS BY TOMORROW...AND INTO TUE NIGHT
AS WELL.  DEEPER DISCUSSION NOTED BELOW BUT ALTHOUGH NO FIRE
HEADLINES AS OF YET....POTENTIAL WILL CERTAINLY BE ELEVATED WITH
BRISK NW WINDS AND DRY CONDITIONS WITH MON MOST LIKELY RED FLAG
WINDOW.

PATTERN EVENTUALLY BECOMES PROGRESSIVE ENOUGH TO PUSH UPPER LEVEL
RIDGE INTO MO VALLEY BY THU.  THIS WILL INCREASE WARM ADVECTION
SUFFICIENTLY TO KEEP LOW POPS GOING WEST WED NIGHT WITH EVEN
STRONGER THERMODYNAMIC FORCING CONTINUING INTO THU.  CONFIDENCE IN
DETAILS AND CONVECTIVE TRENDS DIMINISH INTO THE WEEKEND HOWEVER.
GFS IS MUCH MORE AGGRESSIVE PUSHING WARM SECTOR INTO IA BY FRI
NIGHT...QUICK LOOK AT 00Z ECMWF KEEPS WARM FRONT TO OUR SOUTH WHILE
00Z GEM HAS LARGE SPRAWLING OH VALLEY SURFACE HIGH KEEPING BEST
INSTABILITY TO OUR WEST UNTIL AT LEAST FRI.  BEST POTENTIAL MAY BE
JUST BEYOND CURRENT VALID PERIOD SUN WHEN 00Z GFS/ECMWF BOTH LIFT
SURFACE LOW SOMEWHERE INTO MO RIVER VALLEY AND WARM SECTOR INTO IA.
ALTHOUGH CONFIDENCE IN DETAILS IS LOW...OVERALL PATTERN OF MOST
MODELS STILL SUPPORTS PRECIP OF SOME SORT THU INTO SAT SO HAVE KEEP
CHANCE WORDING WITH ACTIVE PATTERN AND TEMPS SLOWLY WARMING ONCE
AGAIN.

&&

.FIRE WEATHER...
FORECAST SOUNDINGS SUGGEST LOW LEVEL MOISTURE LEVELS CONTINUING TO
DROP THROUGH MIDWEEK WITH DEWPOINTS DURING AFTERNOON MIXING FALLING
INTO THE TEENS CENTRAL AND NORTH MON AND TUE.  MON MAY BE THE MOST
LIKELY DAY FOR RED FLAG POTENTIAL AS SUSTAINED WIND SPEEDS SHOULD
REACH 25 MPH NE THIRD COMBINED WITH MIN RELATIVELY HUMIDITIES JUST
BELOW 25 PERCENT.  DEWPOINTS CONTINUE TO FALL INTO TUE AS WELL BUT
COINCIDENT DROP IN TEMPS RESULTS IN RELATIVE HUMIDITIES A TAD HIGHER
WITH WINDS NOT QUITE AS STRONG EITHER.  STILL AN ELEVATED POTENTIAL
HIGHLIGHTED IN HWO BUT NOT SUFFICIENT FOR HEADLINE CONCERNS AT THE
MOMENT.  COULD MIX TO 2.5KM TODAY...DROPPING TO 1.5KM MON AND TUE.

&&

.AVIATION...08/18Z
WIDESPREAD VFR CONDITIONS ARE FORECAST FOR THE ENTIRE PERIOD WITH SW
SURFACE WINDS BECOMING NORTHWEST ON MONDAY MORNING BEHIND COLD FRONT.

.DMX WATCHES/WARNINGS/ADVISORIES...NONE.
