Area forecast discussion, Apr 15, 3:30 AM CDT, 18 minutes before
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE QUAD CITIES IA IL
330 AM CDT TUE APR 15 2008
.SYNOPSIS...
LATEST SFC ANALYSIS WAS INDICATING LARGE RIDGE COMPLEX CONTINUING TO
MIGRATE EAST-SOUTHEAST ACRS THE CENTRAL GRT LKS AND DOWN ACRS THE
LOW MS RVR VALLEY. SOME SFC CYCLOGENESIS GOING ON OVER THE MT/ND
BORDER..OTHERWISE THE MAIN FEATURE OF NOTE IS THE EVER TIGHTENING
PRESSURE GRADIENT ACRS MUCH OF THE PLAINS AND UPPER MS RVR VALLEY.
ALOFT...W/V IMAGERY WAS INDICATING A LARGE HIGH LEVEL MOISTURE PLUME
RIDING SUBSTANTIAL OMEGA TYPE UPPER RIDGE OVER THE NORTHERN PLAINS
AND MIDWEST.
&&
.SHORT TERM...TODAY AND TONIGHT...
MAIN FCST CHALLENGE IN THE NEAR TERM WILL BE HOW WINDY AND WARM
TODAY IN ROBUST RETURN FLOW REGIME. SOUTHWESTERLY LLVL JET IS FCST
TO INCREASE TO 30-40 KTS BY LATE AFTERNOON ACRS MOST OF THE
NORTHWEST 2/3S OF THE DVN FCST AREA...AND CONTINUE TO INCREASE TO
50+ KTS OVERNIGHT. STOUT WAA/WARMING REALIZED MORE JUST ALOFT IN THE
5-10K FT LAYER...WITH SUBSTANTIAL WARM WEDGE/INVERSION INHIBITING
TRANSLATION TO THE SFC. STILL...MIXING TO BASE OF MAIN INVERSION
SUPPORTS WIDESPREAD LOW TO MID 60S OVER THE ENTIRE FCST AREA. ANY
DEEPER MIXING CLOSE TO H85 MB COULD TRANSLATE TO THE FIRST 70 DEGREE
READING OF THE SEASON...BUT WON/T GO QUITE THAT WARM AND WILL KEEP
THE ALREADY ADVERTISED VALUES GOING IN THE GRIDS...WIDESPREAD MID
60S AND LET TEMPS BEAT ME ON THE HIGH SIDE IF THEY CAN. THE SAME
INHIBITING INVERSION ALOFT SHOULD LIMIT THE NEED FOR A WIND ADVISORY
THIS AFTERNOON FOR ALL BUT THE NORTHWEST 4-6 COUNTIES. WILL GO WITH
AN ADVISORY FOR AREAS FROM WEST OF IOWA CITY...UP TO INDEPENDENCE
AND MANCHESTER FROM NOON TO EARLY EVENING. EVEN IN THESE COUNTIES THE
NEED FOR A ADVISORY MAY BE MARGINAL WITH SUSTAINED WINDS IN THE MID
TO UPPER 20S...AND GUSTS TO 40 MPH MORE PREVALENT THEN 30+ AND GUSTS
TO 45 MPH.
TONIGHT...ALTHOUGH SFC WINDS SHOULD DECREASE SOME WHILE THE LLVL JET
ROARS JUST ALOFT AT 5K FEET...STILL A BLUSTERY NIGHT IN STORE FOR THE
REGION. LOW TEMPS SHOULD BE KEPT UP FROM DIPPING BELOW THE 40S IN
MOST OF THE DVN CWA. ..JDH..
.LONG TERM...WEDNESDAY THROUGH NEXT MONDAY...
ANOTHER STRETCH OF ACTIVE WEATHER COMING UP WITH POTENTIAL FOR
ADDITIONAL FLOODING.
WEDNESDAY...SEASONABLY STRONG LOW PRESSURE TRACKS ACROSS NORTHERN
MINNESOTA. TIGHT GRADIENT WILL EXIST AHEAD OF COLD FRONT WITH 850 MB
WINDS OF 65 KNOTS. POTENTIALLY THIS IS A WIND ADVISORY SITUATION BUT
GRADIENT RELAXES SOME IN THE AFTERNOON LESSENING THE THREAT. IF
LATER MODELS SHOW HIGHEST WINDS LINGERING LONGER INTO THE AFTERNOON
THAN CURRENTLY SUGGESTED THEN WIND ADVISORY WOULD BE PRUDENT. OTHER
NOTE OF INTEREST IS WILL MOLINE REACH THE FIRST 70 DEGREE MAX
TEMPERATURE SINCE OCTOBER 30 2007 (A STRETCH OF 169 DAYS). AXIS OF
WARMEST AIR SLIPS OFF TO THE EAST BY 18Z BUT WITH PLENTY OF SUNSHINE
SHOULD BE ABLE TO REACH 70 FROM MOLINE AND POINTS SOUTH AND EAST.
AREAS TO THE NORTHWEST WE WILL KEEP IN THE 60S.
THURSDAY THROUGH SATURDAY...STRONG HEIGHT FALLS SEEN ALONG THE WEST
COAST FROM LAST EVENINGS UPPER AIR ANALYSIS IS ASSOCIATED WITH NEXT
STRONG SYSTEM TO PUSH INTO THE MIDWEST LATER THIS WEEK. ALL MODELS
EVENTUALLY EVOLVE THIS SYSTEM INTO A SLOW MOVING STACKED SYSTEM.
WITH GULF MOISTURE GETTING INTO THE SYSTEM AND PRECIPITABLE WATER
INCREASING TO OVER AN INCH...POTENTIAL EXISTS FOR ANOTHER SOAKER.
SURFACE LOW IS PROGGED TO TRACK ACROSS CENTRAL AND EASTERN ILLINOIS
WHICH SETS UP THE DVN CWA IN THE COOL OVERRUNNING SIDE OF THE STORM.
BUFKIT RAIN TOTALS ARE ANYWHERE FROM 1/2 INCH IN THE NW CWA TO 1-2
INCHES SE HALF. JUST AS SOME RIVERS GO BACK BELOW FLOOD STAGE THE
POTENTIAL FOR HEAVIER RAIN WOULD CERTAINLY AGGRAVATE THE ONGOING
FLOODING SITUATION OR RENEW THE FLOODING. LATER SHIFTS WILL HAVE TO
MONITOR FOR POSSIBLE FLOOD WATCH. HAVE FAVORED THE ECMWF MODEL WITH
ITS SLOWER MOVEMENT CONSIDERING THE CLOSED NATURE OF THIS SYSTEM.
THE HIGHEST QPF AND THEREFORE POPS WILL BE FROM THURSDAY AFTERNOON
INTO FRIDAY...THEN TAPER OFF THE PRECIPITATION SLOWLY FROM WEST TO
EAST BY SATURDAY. INSTABILITY WILL BE MINIMAL BUT HAVE MENTIONED
ISOLATED THUNDERSTORMS LATE WEDNESDAY NIGHT AHEAD OF COLD FRONT AND
AGAIN THURSDAY EVENING WHEN THE STRONGEST LIFT OCCURS...ACCORDING TO
THE TIME HEIGHT SECTIONS. HAVE LOWERED TEMPS SEVERAL DEGREES FOR
THURSDAY AND FRIDAY WITH LOW CLOUDS...RAIN AND WINDS TURNING
NORTHEAST.
EARLY NEXT WEEK...WARMER TEMPS RETURNING AHEAD OF DEEP TROUGH
PROGGED TO PUSH THROUGH THE WESTERN U.S.
..HAASE..
&&
.AVIATION...
SKY COVER AND VSBYS TO BE VFR CONDITIONS THROUGH TAF FCST PERIOD.
SOME UPPER RIDGE-RIDING CI SPILLING DOWN ACRS THE AREA TODAY AND
TONIGHT POSSIBLY TO BKN LEVELS AT TIME. MAIN AVIATION CONCERN WILL
BE STRONG SOUTHERLY SFC WINDS AS TIGHT PRESSURE GRADIENT BUILDS INTO
THE AREA TODAY...ESPECIALLY AT THE CID AND DBQ TERMINALS AFTER 18Z.
WIND GUSTS COULD APPROACH 37 KTS AT TIMES THROUGH 00Z WED. ANY
SUBSTANTIAL WIND DECOUPLE TONIGHT AT THE SFC WILL CREATE THE NEED TO
ADVERTISE LLVL WIND SHEAR WITH 40-55 KT SOUTHWEST FLOW IN THE 2-5K
FT LAYER OVER MOST TERMINALS AFTER 03Z. ..JDH..
&&
.HYDROLOGY...
CURRENT FLOOD WARNINGS REMAIN VALID WITH RIVERS EITHER ACHIEVING
CREST TODAY OR BUILDING TOWARD A CREST BY LATE IN THE WEEK. THERE IS
CONCERN REGARDING THE STORM SYSTEM FOR LATE IN THE WEEK. DEPENDING
UPON HOW WIDESPREAD AND THE EVENTUAL AMOUNTS OF RAIN THAT FALL...AT A
MINIMUM IT WILL PROLONG THE HIGH RIVER LEVELS.
&&
.DVN WATCHES/WARNINGS/ADVISORIES...
IA...WIND ADVISORY THIS AFTERNOON FOR BENTON-BUCHANAN-DELAWARE-
IOWA-JOHNSON-LINN.

DRIER WEATHER THROUGH MID WEEK SHOULD PERMIT THE TRIBUTARIES TO FALL...BUT THE MISSISSIPPI RIVER WILL CONTINUE RISING THROUGH THE WEEK AT MOST LOCATIONS. AT THIS TIME...IT DOES NOT APPEAR THAT LATE WEEK RAINFALL WILL SIGNIFICANTLY ADD TO THE FLOODING PROBLEM...BUT STAY TUNED TO LATER FORECASTS AS THIS COULD CHANGE. .SPOTTER INFORMATION STATEMENT... SPOTTER ACTIVATION WILL NOT BE NEEDED. WOLF/12
