AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE QUAD CITIES IA IL
1147 PM CDT SUN APR 8 2012

.AVIATION...
VFR SKY AND VISIBILITY EXPECTED THROUGH 06Z ON THE 10TH. MAIN
CONCERNS THIS CYCLE THEN FOCUS ON WINDS THROUGH THE PERIOD. AS OF
MIDNIGHT WINDS WERE GRADUALLY SWITCHING FROM SOUTHWEST TO
NORTHWEST AS A COLD FRONT MOVED THROUGH THE AREA. WINDS ARE
LESS THAN 10 KTS FOR MOST OF THE AREA SO THERE ARE NO FM GROUPS
INDICATING THIS WIND SWITCH...THOUGH IT SHOULD HAPPEN FOR ALL
TERMINALS BY 09Z. MONDAY MORNING...ABOUT 15-16Z...WINDS TO
INCREASE OUT OF THE NORTHWEST AROUND 15KTS WITH GUSTS TO
25KTS...INCREASING IN THE AFTERNOON TO 15-20KTS WITH GUSTS
25-30KTS. WINDS TO DIMINISH AGAIN TO LESS THAN 10KTS AROUND 01Z
MONDAY EVENING. ..LE..

&&

.PREV DISCUSSION... /ISSUED 310 PM CDT SUN APR 8 2012/

SYNOPSIS...
VERY DEEP MIXING HAS RESULTED IN AFTERNOON TEMPERATURES IN THE LOWER
TO MID 60S NORTH...TO MID TO UPPER 60S CENTRAL AND SOUTH. LOW
DEWPOINTS IN THE UPPER TEENS TO UPPER 20S HAVE RESULTED IN RH VALUES
FROM 18 TO 25 OVER THE CWA...MAKING FOR A DAY MORE TYPICAL OF SUMMER
MOUNTAIN CLIMATES. A SHORT WAVE ROTATING SOUTHEAST OVER MN IS
CREATING SOME MID LEVEL CLOUDINESS OVER NORTHERN IOWA.

SHORT TERM...TONIGHT AND MONDAY...
CLOUDS WILL SPREAD OVER THE CWA THIS EVENING...AND LAST THROUGH AT
LEAST EARLY MORNING BEFORE SWEEPING EAST OF THE CWA. THIS WILL HELP
HOLD TEMPERATURES UP FOR A PORTION OF THE NIGHT...LIMITING
RADIATIONAL COOLING/S MAIN INFLUENCE TO AFTER 2 AM. LOWS IN THE MID
30S NORTHWEST TO LOWER 40S CENTRAL AND SOUTHEAST ARE EXPECTED. WINDS
SHOULD BACK OFF TO AROUND 10 MPH OVERNIGHT...FROM THE NORTHWEST.

MONDAY...WE WILL SEE COLD ADVECTION INCREASE DURING THE
AFTERNOON...BUT SHOULD BEGIN THE DAY WITH DEEP MIXING UNDER A MILD
ATMOSPHERE PROFILE ONCE AGAIN. THUS...HIGHS SHOULD BE REACHED BY
NOON...THEN STEADY TEMPERATURES IN THE MID 50S NORTH TO MID 60S
SOUTH ARE EXPECTED. LOW DEWPOINTS ONCE AGAIN WITH RATHER GUSTY
NORTHWEST WINDS AROUND 25 MPH AT TIMES WILL CONTRIBUTE TO AN
ENHANCED FIRE SPREADING RISK TOMORROW.

ERVIN..

LONG TERM...MONDAY NIGHT THROUGH NEXT SUNDAY...
MONDAY NIGHT AND TUESDAY...30 TO 40 KT NNW H85 MB FLOW WILL STILL
LOOK TO STRONGLY CAA OUT OF CANADA MON NIGHT AS RIDGE AXIS OFF A
SEASONABLY STRONG 1030+ HIGH CONTINUES TO NOSE DOWN ACRS THE REGION
OUT OF MANITOBA AND SASKATCHEWAN. SUB ZERO C H85 TEMPS BY TUE MORNING
RANGING FROM -2 C IN THE SOUTH...TO NEAR -8C IN THE NORTHEAST.
LATEST RUN SHORT RANGE MODELS...AS WELL AS THE EUROPEAN ONES STILL
SUGGEST IN-BUILDING RIDGE GRADIENT TO KEEP WINDS GOING OF AT LEAST 5-
10 KTS AND THE BOUNDARY LAYER MIXED MON NIGHT INTO TUE MORNING. THU
STILL SOME QUESTIONS AND UNCERTAINTY ON HOW COLD TEMPS WILL DIP
AND THE DURATION OF TEMPS AT OR BELOW FREEZING TO WARRANT A TRUE
FROST OR FREEZE THREAT. MAY BE SIMILAR TO LAST FRIDAY WHEN TEMPS
DIPPED TO OR UNDER THE FREEZING MARK...BUT AT A SUCH A SHORT DURATION
THAT IT LIMITED THE FREEZE DAMAGE. BUT WITH THE UNCERTAINTY IT STILL
MAY BE CLOSE IF WINDS CAN DECREASE TO 5 MPH OR A BIT LESS AND WILL
ISSUE A FREEZE WATCH FOR ROUGHLY THE NORTHWEST HALF OF THE DVN CWA
FRO LATE MON NIGHT INTO TUE MORNING. THE SFC WINDS SHOULD REALLY
LIMIT WIDESPREAD FROST FORMATION AS WELL. ANOTHER BLUSTERY DAY TUE
WITH HIGHS ONLY IN THE UPPER 40S TO LOWER 50S IN THE NORTH...AND
PUSHING THE MID 50S SOUTH OF I-80 WITH FULL INSOLATION AND DEEP
MIXING TO GET THOSE VALUES. TUE NIGHT STILL LOOKS TO BE THE PRIME
HARD FREEZE POTENTIAL PERIOD WITH LLVL COLD AIRMASS POOL OVERHEAD.
LATEST PROGS SUGGEST MAIN SFC RIDGE AXIS TO STILL BE JUST TO THE
WEST OF THE CWA BUT CLOSE ENOUGH TO ALLOW FOR A BETTER CHANCE
FOR SFC WIND DECOUPLE...IF THEY DO A CHANCE FOR SOME MID 20S NORTH
OF I-80 ESPECIALLY IN COLD AIR DRAINAGE LOCATIONS. H85 RIDGE COLD
RULE ALSO SUGGESTS SOME MID 2OS POSSIBLE BY EARLY WED MORNING.

WEDNESDAY AND THURSDAY...RIDGE OVERHEAD FOR A WEAK MIXING DAY ON WED
BUT ENOUGH OF THERMAL PROFILE IMPROVEMENT TO SUGGEST WIDESPREAD HIGHS
IN THE MID TO UPPER 50S. WED NIGHT COULD STILL HAVE LINGERING RIDGE
AFFECTS AND QUICK TEMP DROP-OFF AFTER SUNSET. MAY BE ANOTHER CHANCE
AT FROST/FREEZING TEMPS ESPECIALLY EAST OF THE MS RVR IF RETURN FLOW
DOES NOT KICK IN UNTIL DURING THE DAY THU. AS FOR THE DEVELOPING
SOUTHERN STREAM SYSTEM IN THE GRT BSN AND SOUTHERN PLAINS...BOTH THE
12Z GFS AND THE NEW ECMWF HAVE JUMPED BACK NORTHWARD WITH MAIN SFC
CYCLONE ACRS THE NORTHWEST HIGH PLAINS BY 00Z FRI. LINGERING RIDGE
ACTION AT THE SFC AND ALOFT MAY STILL HOLD INCOMING OVERRUNNING
PRECIP AT BAY TO THE WEST OF THE DVN CWA EVEN WITH THIS NEW PLACEMENT
THROUGH 00Z FRI...BUT WILL KEEP THE LOW CHC POPS IN THE WEST FOR
THU AFTERNOON. HIGHS IN THE UPPER 50S WITH INCREASING CLOUDS THU.
THE NEW 12Z RUN ECMWF IS SUGGESTING AN OVERRUNNING RAIN EVENT
BUILDING ACRS THE AREA AS THU NIGHT PROGRESSES AND ISOLATED THUNDER
IN THE SOUTH WITH .2 TO .5 TENTHS OF AN INCH OF RAINFALL BY FRI
MORNING...AND BLOSSOMS HEAVIER RAIN AND THUNDERSTORMS TO THE SOUTH
ACRS MO. THIS IN CONTRAST TO THE 12Z GFS WHICH ALMOST WANTS TO
RETREAT THE MAIN WARM FRONT THROUGH THE CWA THU NIGHT FOR MORE
THUNDERSTORMS ACTIVITY. WILL KEEP THE CHC POPS GOING FOR THU NIGHT
UNTIL THE MODELS AGREE/SETTLE MORE ON A NORTH OR SOUTHWARD SOLUTION.

FRIDAY THROUGH SUNDAY...LATEST SUITE OF MEDIUM RANGE MODELS SUGGEST
THAT SEVERAL TIMING AND HANDLING DIFFERENCES THERE AGAIN FOR THIS
PERIOD...BUT THE GENERAL IDEA OF A MORE ACTIVE WET PERIOD CONTINUES
TO BE ADVERTISED FOR THE END OF THE WEEK AND INTO THE WEEKEND AS
SOUTHWESTERLIES SPILL ACRS THE UPPER MIDWEST AND WARM MOIST CONVEYOR
DEVELOPS UP OFF THE WESTERN GULF AND TOWARD THE MID TO UPPER MS RVR
VALLEY REGIONS. POSSIBLY MCS INITIATION OVER THE LOCAL AREA FRI NIGHT
INTO EARLY SAT. THEN ACTIVE SOUTHERN STREAM WILL LOOK TO RELOAD WITH
ANOTHER LOW PRESSURE CENTER IN THE SOUTHWESTERN PLAINS ON SAT AND AS
IT TRIES TO LIFT OUT NORTHEASTWARD...IGNITING ANOTHER ELEVATED MCS OR
SIMILAR COMPLEX IN OR NEAR THE AREA BY NEXT SAT NIGHT. WILL HAVE
PLENTY OF MODERATE CHC POPS DURING THIS TIME FRAME TO COVER AN
INCREASINGLY ACTIVE AND WET LOOKING PERIOD IN THE EXTENDED.   ..12..
