AREA FORECAST DISCUSSION

320 AM CST FRI MAR 2 2007

.DISCUSSION...
RECORD OR NEAR RECORD STRENGTH STORM SYSTEM LIFTING NE FROM THE CWA
ATTM. GFS/NAM 500 MB ANOMALIES ARE -3 SIGMA WITH THIS STORM WHICH
PLACES IT AT RECORD OR NEAR RECORD INTENSITY. 08Z SFC MAP SHOWS SFC
LOW BETWEEN KLNR AND KDLL IN SWRN WI. 00Z UPPER AIR CHARTS SHOW A
DEEPENING LOW ALOFT AS WELL...WITH 12-HR 230 M HEIGHT FALLS AT DVN.
AT THE SFC...VERY STRONG WESTERLY WINDS ARE PERSISTING WITH GUSTS OF
40+ MPH. MSAS SFC ANALYSIS SHOWS ISALLOBARIC RISE MAX ACRS THE W
CTRL CWA ATTM AND MOVG EWD. RADAR AND SFC OBS INDICATE -SN FALLING
ACRS MUCH OF THE CWA ATTM. THE MORE SIGNIFICANT ISSUE IS THE BLSN
ASSOCIATED WITH THE STRONG WINDS. IN MANY CASES...ESPECIALLY IN
RURAL AREAS...GROUND-BLIZZARD CONDITIONS ARE OCCURRING WITH
RESTRICTED HORIZONTAL VISIBILITY BUT GOOD VERTICAL AND ANGLED
VISIBILITY. NEVERTHELESS...AREA ROADS ARE MOSTLY TO TOTALLY SNOW AND
ICE COVERED. RURAL AREAS ARE SEEING THE WORST CONDITIONS WITH NEAR
WHITEOUT CONDITIONS BEING REPORTED. WE JUST RECEIVED NOTICE THAT
I-80 HAS BEEN CLOSED FROM I-74 TO THE ILLINOIS STATE LINE IN IA.

MOST OF MY FOCUS WAS ON THE FIRST 24-36 HRS OF THIS FCST PD. FCST
CHALLENGES PRECIP OCCURRENCE AND WIND SPEEDS. WITH CYCLONIC
FLOW...AMPLE MOISTURE AND AMPLE PVA...PERIODS OF SNOW ARE LIKELY
TODAY ACRS MUCH OF THE CWA. THE ONLY EXCEPTION MAY BE THE EXTREME S
WHERE THESE PARAMETERS WILL BE SLIGHTLY LESS IN MAGNITUDE. STRONG
GRADIENT WINDS ARE EXPECTED TODAY AS THE LOW LIFTS NE. ALTHOUGH THE
WINDS WILL NOT MEET HIGH WIND WARNING CRITERIA...THEY SHOULD MEET
ADVISORY CRITERIA. ALSO...MUCH OF THE NWRN CWA WILL HAVE SN/BLSN
ISSUES. ALTHOUGH I DO NOT EXPECT SNOW ACCUMULATIONS TO MEET ADVISORY
CRITERIA...I DO EXPECT THE BLOWING SNOW TO CAUSE TRAVEL PROBLEMS ON
AREA ROADS. THUS THE SN/BLSN ADVISORY IS WARRANTED. /SNOW
ACCUMULATIONS WILL BE AROUND 0.5-1.5 INCHES./

THE AMERICAN AND EUROPEAN MODELS ARE IN RATHER GOOD AGREEMENT WITH
THE TRACK OF THE SFC AND 500 MB LOW THROUGH AROUND 30 HRS. AFTER
THAT...THEY BEGIN TO DIVERGE. CLOSER TO THE PRESENT...THE MODELS ARE
SLOWING THE NEWD MOVEMENT OF THE LOW. THE MAIN CAUSE IS THE 150+ JET
STREAK PRESENTLY MOVING ONSHORE TO BAJA CALIFORNIA FROM THE ERN
PACIFIC OCEAN. ONCE THAT JET STREAK LIFTS OUT...THE SYSTEM WILL
DEPART MORE QUICKLY.

AS THE SYSTEM PULLS OUT...TEMPS WILL BECOME QUITE COLD...COMPARED TO
LONG-TERM AVERAGES. ALTHOUGH TEMPS WILL NOT BE AS COLD AS IN
FEBRUARY...THEY WILL BE WELL BELOW NORMAL. THEY WILL NOT LAST FOR AS
LONG THOUGH. I MADE ONLY MINOR TWEAKS TO GOING FCST MINS SUNDAY INTO
TUESDAY.

TEMPS LOOK TO MODERATE TOWARD THE MIDDLE OF NEXT WEEK. UPPER AIR
FLOW BECOMES MORE ZONAL...ALLOWING FOR WARMER TEMPS TO RETURN.

THIS HAZARDOUS WEATHER OUTLOOK IS FOR PORTIONS OF NORTH CENTRAL
ILLINOIS...NORTHWEST ILLINOIS...WEST CENTRAL ILLINOIS...EAST
CENTRAL IOWA...NORTHEAST IOWA...SOUTHEAST IOWA AND NORTHEAST
MISSOURI.

.DAY ONE...TODAY AND TONIGHT

SOME LIGHT FREEZING RAIN WITH MINOR ICE ACCUMULATIONS OF UNDER A
TENTH OF AN INCH...WILL CONTINUE TO BE POSSIBLE THROUGH MID MORNING
ALONG AND NORTH OF THE ROUTE 20 CORRIDOR. EARLY MORNING MOTORISTS
SHOULD PREPARE FOR LOCALIZED SLICK SPOTS IN THESE AREAS. A FREEZING
RAIN ADVISORY CONTINUES UNTIL 9 AM FOR FAR NORTHEAST IOWA INTO
EXTREME NORTHWEST ILLINOIS.

A POWERFUL STORM SYSTEM WILL IMPACT THE REGION TODAY THROUGH
SATURDAY. THIS SYSTEM WILL BRING ANOTHER ROUND OF SHOWERS AND
THUNDERSTORMS ACROSS MUCH OF THE AREA THROUGH NOON TODAY. A FEW
STORMS ALONG AND SOUTHEAST OF A LINE FROM FAIRFIELD IOWA...TO
PRINCETON ILLINOIS...MAY BE STRONG ENOUGH TO PRODUCE HAIL UP TO
THE SIZE OF PENNIES. THE STORM PREDICTION CENTER HAS OUTLOOKED
EXTREME SOUTHEAST IOWA...NORTHEAST MISSOURI AND WEST CENTRAL
ILLINOIS FOR A SLIGHT RISK OF SEVERE WEATHER TODAY.

THIS NEXT ROUND OF SHOWERS AND STORMS THIS MORNING MAY PRODUCE AN
ADDITIONAL HALF INCH...UP TO AN INCH OF RAINFALL THROUGH NOON. THIS
KIND OF RAINFALL AND RUN OFF OVER PARTIALLY FROZEN GROUND...ON TOP OF
THE HALF INCH TO AN INCH THAT HAS ALREADY FALLEN OVERNIGHT...WILL
LEAD TO SIGNIFICANT RISES ON AREA RIVER AND STREAM LEVELS...WITH MANY
GOING OUT OF BANK AND PAST THE FLOOD STAGE. ICE ACTION WILL ALSO ADD
TO ANY RIVER OR STREAM FLOODING POTENTIAL. FLASH FLOODING OF LOW-
LYING AND URBAN AREAS WILL ALSO BE A THREAT. A FLOOD WATCH CONTINUES
FOR THE ENTIRE AREA THROUGH FRIDAY EVENING.

LATE THIS AFTERNOON AND TONIGHT...A TEMPORARY BREAK IN THE
PRECIPITATION IS EXPECTED DURING THE AFTERNOON...BEFORE COLD AIR
WRAPPING IN BEHIND THE EXITING STORM SYSTEM BRINGS THE THREAT OF
SNOW. SNOW IS EXPECTED TO OVERSPREAD THE AREA FROM WEST TO EAST FROM
LATE AFTERNOON...AND LAST INTO THE OVERNIGHT. WITH THE SNOW
CONTINUING INTO FRIDAY...AREAS NORTHWEST OF A CEDAR RAPIDS...TO
DYERSVILLE LINE WILL EXPERIENCE SNOWFALL AMOUNTS OF 4 TO 7 INCHES BY
FRIDAY AFTERNOON. THIS AREA IS UNDER A WINTER STORM WARNING TONIGHT
THROUGH NOON FRIDAY. AREAS GENERALLY ALONG AND NORTH OF A LINE FROM
WILLIAMSBURG...TO CLINTON...AND TO MOUNT CARROLL WILL RECEIVE FROM 2
TO 5 INCHES OF NEW SNOWFALL BY MIDDAY FRIDAY. THESE AREAS ARE UNDER
A WINTER WEATHER ADVISORY FOR TONIGHT THROUGH NOON FRIDAY. ALONG
WITH THE ARRIVAL OF THE SNOW...STRONG WEST WINDS OF 25 TO 40 MPH...
WITH GUSTS OF AT LEAST 50 MPH WILL SWEEP ACROSS THE AREA THIS
AFTERNOON AND ESPECIALLY TONIGHT. THESE STRONG WINDS WILL COMBINE
WITH THE MORE SUBSTANTIAL SNOW BANDS TO PRODUCE NEAR WHITEOUT OR
BLIZZARD-LIKE CONDITIONS AT TIMES THROUGH FRIDAY MORNING.

FOR THE REST OF THE AREA GENERALLY ALONG AND SOUTH OF THE INTERSTATE
80 CORRIDOR...A HIGH WIND WARNING IS IN EFFECT FOR LATE THIS
AFTERNOON AND TONIGHT. HIGH WINDS SUSTAINED BETWEEN 30 AND 40 MPH
WITH GUSTS OVER 55 MPH WILL OVERSPREAD THE WARNING AREA FROM
SOUTHWEST TO NORTHEAST FROM LATE THIS AFTERNOON THROUGH TONIGHT.
THESE HIGH WINDS WILL THEN LAST INTO FRIDAY MORNING. THESE WIND
SPEEDS WOULD BE CAPABLE OF PRODUCING WIND DAMAGE TO TREES AND POWER
LINES...ESPECIALLY IN LOCATIONS THAT RECEIVED DAMAGE IN THE ICE STORM
LAST WEEKEND. IN ADDITION...THE HIGH WINDS COMBINED WITH PERIODS OF
LIGHT TO MODERATE SNOW TONIGHT MAY REDUCE VISIBILITIES BELOW A MILE
AT TIMES.

.DAYS TWO THROUGH SEVEN...FRIDAY THROUGH WEDNESDAY

OCCASIONAL LIGHT SNOW AND WINDY CONDITIONS WILL THEN LAST INTO FRIDAY
EVENING. ADDITIONAL LIGHT SNOW ACCUMULATIONS WILL OCCUR FRIDAY
AFTERNOON AND EVENING...WITH WINDS OF 20 TO 30 MPH AND GUSTS STILL
OVER 40 MPH. THIS WILL CONTINUE TO CAUSE BLOWING AND DRIFTING SNOW
WITH REDUCED VISIBILITIES IN AREAS THAT RECEIVE SEVERAL INCHES OF
SNOW ACCUMULATION THURSDAY NIGHT AND FRIDAY.

.SPOTTER INFORMATION STATEMENT...

SPOTTER ACTIVATION MAY BE NEEDED THROUGH NOON SOUTH OF THE INTERSTATE
80 CORRIDOR.
