AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE QUAD CITIES IA IL
325 AM CDT WED APR 11 2012

.SYNOPSIS...
DEEP NORTHWEST FLOW PERSISTS OVER THE REGION EARLY THIS AM WITH
STAGNANT HIGH AMPLITUDE UPPER AIR PATTERN IN PLACE... WITH
DEEP TROUGHING OVER THE EASTERN CONUS AND EASTERN PACIFIC AND
RIDGING OVER THE ROCKIES. AT THE SFC... COLD CANADIAN HIGH
PRESSURE CENTERED OVER MANITOBA PROVINCE WITH RIDGE AXIS
EXTENDING SWD THROUGH MO RVR VLY. HARD FREEZE IN PROGRESS
PORTIONS OF THE NORTHERN CWA WHERE TEMPS ALREADY IN MID 20S AT
2 AM. ELSEWHERE... TEMPS NEARING THE FREEZING MARK WITH WINDS
GENERALLY AROUND 5 KTS.

&&

.SHORT TERM...TODAY AND TONIGHT...
MAIN CHALLENGE REMAINS LOW TEMPS TNGT AND FROST/FREEZE POTENTIAL.
FAIRLY TRANQUIL CONDITIONS NEXT 24 HRS AS SFC HIGH PRESSURE RIDGE
CONTINUES TO DOMINATE.

TDY... CONTINUED COOL AND SUNNY WITH MAIN STORY BEING MUCH LESS
WIND THAN RECENT DAYS. NW WINDS INCREASE TO 10-15 KTS WITH SOME
LOCAL GUSTS TO NEAR 20 KTS (MAINLY EAST) THIS AM WITH MIXING...
BUT WINDS TO DROP OFF TO LIGHT AND VARIABLE BY MID-LATE PM WITH
SFC HIGH BUILDING IN. NAM/GFS BUFR SOUNDINGS SHOW MIXING TO 850 MB
WHICH YIELDS WIDESPREAD HIGHS NR 50/L50S... BUT POTENTIAL TO
MIX A LITTLE HIGHER SIMILAR TO WHAT WE/VE SEEN IN THIS REGIME
WITH DRY AIR...DRY GROUND AND ABUNDANT SUNSHINE. SO HAVE TACKED ON
COUPLE DEGS TO ACCOUNT FOR THIS WHICH YIELDS WIDESPREAD MID 50S
WITH RANGE GENERALLY 52-57F. THIS ALSO MATCHES UP WELL WITH THE
MODELS PROGGED LOW LEVEL THICKNESS AND VERIFICATION OF HIGHS
YSTDY.

TNGT... WEAKENING SFC HIGH PRESSURE RIDGE OVERHEAD DURING THE EVE
TO SLIDE E/SE OVRNGT WITH LIGHT RETURN FLOW S/SE (3-5 KTS) SHOWN
MOST AREAS BY 12Z THU. STRONG LOW LEVEL INVERSION...DRY AIR...
MAINLY CLEAR SKIES AND NEAR CALM TO CALM WINDS TO PROMOTE IDEAL
RADIATIONAL COOLING SETUP FOR RAPID PLUMMET OF TEMPS AFTER SUNSET.
RETURN FLOW THAT DEVELOPS LATE LOOKS TO BE LIGHT ENOUGH TO NOT
HAVE TOO MUCH IMPACT ON MINS THAT SHOULD BE AT OR BELOW COLDEST
GUIDANCE WITH IDEAL RADIATIONAL COOLING MUCH OF THE NGT. MIN TEMP
TECHNIQUE USING STRENGTH OF INVERSION AND PROGGED 850 MB TEMP 12Z
THU SUPPORTS WIDESPREAD MID AND UPPER 20S ON LOWS EASTERN 1/2 TO
2/3 WITH WARMEST READINGS STILL AROUND 30F SUGGESTED OVER SW
PORTIONS OR ROUGHLY WEST OF KCID-KFSW LINE WHERE RETURN FLOW TO
BECOME ESTABLISHED SOONER. MAIN DIFFERENCE TNGT WILL LIKELY BE
MORE WIDESPREAD FROST THAN WE/VE SEEN PAST FEW MORNINGS AS WINDS
TO BE NEAR CALM TO CALM ALLOWING LOW LEVEL MOISTURE TO POOL
RESULTING IN SOMEWHAT HIGHER DEWPTS. AFTER MUCH DELIBERATION ON
HEADLINES HAVE OPTED TO GO WITH ONE LAST FREEZE WARNING THE ENTIRE
CWA ALTHOUGH COULD BE MARGINAL OVER PORTIONS OF WEST... BUT THIS
DEPENDENT ON ONSET OF RETURN FLOW AND OPTED TO ERR ON SIDE OF CAUTION.
MOVED UP START TIME TO 04Z FROM PAST FEW NGTS GIVEN SHARP DROP OFF
IN TEMPS THIS EVE.   05

.LONG TERM...THURSDAY THROUGH NEXT TUESDAY...
COLD CANADIAN HIGH PRESSURE JUST TO THE EAST OF THE CWFA AT
SUNRISE WILL CONTINUE MOVING EAST DURING THE DAY ALLOWING RETURN
FLOW TO DEVELOP AND BECOME STRONGER. THE MORNING HOURS WILL BE
DRY. THE QUESTION TURNS TO HOW FAST WILL MOISTURE ARRIVE IN THE
AFTERNOON.

A MAJORITY OF THE AFTERNOON WILL BE DRY FOR THE ENTIRE AREA. MCS AND
LIFT TOOLS COMBINED WITH THE HEAVY RAIN TOOL AND CONDENSATION
PRESSURE DEFICITS SHOW A NICE THETA E GRADIENT ENTERING THE WESTERN
CWFA DURING THE AFTERNOON. MID LEVEL LAPSE RATES ARE MARGINAL AND
CONDENSATION PRESSURE DEFICITS CONTINUE TO REMAIN HIGH IN THE
1000-850MB LAYER. THUS ANY PRECIP APPROACHING THE AREA WITH THE
ASSOCIATED VORT MAX WILL STRATIFY OUT OR EVAPORATE AS IT ARRIVES.
THUS WILL GO WITH LOW SCHC POPS IN THE FAR SOUTHWEST PARTS OF THE
CWFA VERY LATE IN THE AFTERNOON.

THURS NIGHT THE MCS/LIFT/HEAVY RAIN TOOLS INDICATE THERE WILL BE AN
INITIAL SHOT OF SPRINKLES OR LIGHT SHOWERS ASSOCIATED WITH THE THETA
E GRADIENT MOVING NORTHEAST ACROSS THE CWFA. AS THE LLJ BEGINS TO
VEER INTO THE CWFA BY MIDNIGHT ANOTHER BAND OF PRECIPITATION SHOULD
BEGIN ENTERING THE AREA. THE STRONGER LLJ AND ASSOCIATED CONVERGENCE
OF MOISTURE ON AN ELEVATED BOUNDARY INDICATE SOME TSRA WILL BE
ASSOCIATED WITH THE SECOND BAND.

THE SECOND BAND MOVES ACROSS THE AREA AFTER MIDNIGHT BUT WILL ALSO
SLOWLY STRATIFY OUT. THUS THE BETTER TSRA CHANCES WILL BE ACROSS THE
SOUTHWEST HALF OF THE CWFA AND WILL BE OF AN ELEVATED NATURE.

FRIDAY MORNING...THE SECOND BAND OF CONVECTION FROM THURSDAY NIGHT
WILL EXIT THE CWFA DURING THE MORNING HOURS. THERE WILL LIKELY BE A
LULL IN ACTIVITY UNTIL THE NEXT VORT MAX/SHORTWAVE ARRIVES DURING
THE AFTERNOON AND INITIATES NEW CONVECTION.

SEVERAL SHORTWAVES AND ASSOCIATED VORT MAXES MOVE THROUGH THE CWFA
FRIDAY NIGHT WITH THE LLJ POINTING RIGHT INTO THE CWFA. POPS FOR
FRIDAY NIGHT HAVE BEEN INCREASED TO HIGH LIKELY BUT MAY STILL BE A
BIT ON THE LOW SIDE GIVEN A 50 KNOT LLJ POINTING INTO THE CWFA.

SATURDAY ON...
MODEL CONSENSUS CONTINUES A VERY ACTIVE WX PATTERN WITH RAIN CHANCES
EACH DAY. LIKELY POPS SAT/SAT NIGHT LOOK REASONABLE WITH A SFC WAVE
MOVING THROUGH THE AREA. A COLD FRONT MOVING THROUGH ON
SUNDAY/SUNDAY NIGHT MAKES THE CHC POPS ON SUNDAY LOOK REASONABLE.
DIFFERENCES IN THE MODELS RESULT IN LIKELY POPS SUN NIGHT WHICH
COULD BE ON THE HIGH SIDE.

MODEL SOLUTIONS BECOME MORE VARIED ON WHAT WILL HAPPEN MON/TUES
WHICH IS TRACEABLE TO HOW THE RESPECTIVE MODELS PHASE ENERGY COMING
OUT OF THE SOUTHWEST CONUS TROF. CURRENT CONSENSUS GENERALLY GIVES
CHC POPS FOR MON/TUES WHICH LOOKS REASONABLE GIVEN THE SPREAD OF
MODEL SOLUTIONS.   08

&&

.AVIATION... /ISSUED 1142 PM CDT TUE APR 10 2012/

VFR CONDITIONS WILL CONTINUE THROUGH WEDNESDAY EVENING AS HIGH PRESSURE
BUILDS INTO THE REGION. NORTHWEST WINDS WILL BE AROUND 5KTS
OVERNIGHT AND THEN INCREASE TO AROUND 10KTS BY LATE MORNING. AS
THE CENTER OF THE HIGH MOVES INTO EASTERN IOWA LATE WEDNESDAY
AFTERNOON WINDS WILL BECOME LIGHT AND VARIABLE.
