AREA FORECAST DISCUSSION

1002 AM CST SAT MAR 10 2012

.DISCUSSION...
1001 AM CST

TEMPS HAVE BEEN A BIT SLOW TO WARM THIS MORNING VS THE ANTICIPATED
DIURNAL TREND WE HAD GOING IN THE GRIDS...HOWEVER BASED ON MORNING
SOUNDINGS FROM ILX/DVN WOULD SEEM OUR FORECAST HIGH TEMPS ARE
STILL VERY MUCH ACHIEVABLE. HAVE MADE SOME ADJUSTMENTS TO HOURLY
TEMP GRIDS TO SLOW THE WARM UP A BIT BUT NOT PLANNING ANY CHANGES
TO HIGH TEMP GRIDS AND NO PLANS AT THIS TIME TO UPDATE ZFP.

.PREV DISCUSSION...
352 AM CST

SEVERAL FORECAST CONCERNS THIS MORNING INCLUDING POTENTIAL RED
FLAG FIRE WEATHER CONDITIONS TODAY...TIMING OF RAIN AND POTENTIAL
FOR THUNDER LATE SUNDAY-MONDAY AND CONTINUED UNSEASONABLY WARM
TEMPS THROUGH THE PERIOD ESPECIALLY MONDAY AND WEDNESDAY. SEE FIRE
WEATHER DISCUSSION FOR DETAILS ON RED FLAG CONDITIONS.

HIGH PRESSURE HAS MOVED EAST THE CWA THIS MORNING AND WAS
ANALYZED OVER THE CENTRAL LAKES AND MID-OHIO VALLEY AT 09Z. TO THE
NORTH AND NORTHWEST...STRONG SURFACE PRESSURE FALLS OF NEARLY 6 MB
IN 3 HOURS WERE OCCURRING ACROSS THE UPPER MISSISSIPPI VALLEY AND
WESTERN ONTARIO IN ASSOCIATION WITH DEEP LOW PRESSURE OVER
NORTHERN MANITOBA AND ASSOCIATED WARM FRONTAL TROUGH WHICH EXTENDS
INTO NORTHERN IOWA. THIS WARM FRONT WILL PUSH QUICKLY EAST ACROSS
THE WESTERN LAKES REGION THIS MORNING...WITH SUNNY SKIES AFTER A
LITTLE MORNING CIRRUS...GUSTY SOUTHWEST WINDS AND MUCH WARMER
TEMPERATURES IN STORE TODAY. EXCEPTIONALLY DRY LOW-MID LEVELS AS
DEPICTED IN LARGE T/TD DEPRESSIONS IN REGIONAL AND UPSTREAM 00Z
RAOBS...WHICH CONTINUES TO SUPPORT POTENTIAL FOR DEEPER MIXING
THAN MODEL SOUNDINGS INDICATE. THUS HAVE MAINTAINED FORECAST
AFTERNOON TEMPS A CATEGORY ABOVE EVEN WARMEST MAV GUIDANCE
NUMBERS. THIS ALSO SUPPORTS STRONGER FORECAST WINDS WITH 20-30 MPH
SUSTAINED WINDS AND GUSTS TO 35-40 MPH ESPECIALLY ACROSS THE
NORTHERN THIRD OR HALF OF THE CWA. THE GRADIENT RELAXES A BIT
TONIGHT AS CANADIAN LOW AND WARM FRONTAL TROUGH MOVE OFF TO THE
EAST...AND RIDGING BUILDS ALOFT. THIS WILL ALLOW WINDS TO DIMINISH
SIGNIFICANTLY DURING THE EVENING HOURS.

ATTENTION THEN TURNS TO APPROACHING UPPER LOW WHICH IS CURRENTLY
SPINNING ALONG THE ARIZONA/SONORA BORDER. GUIDANCE HAS CONTINUED TO
SLOW ITS JOURNEY AS IS TYPICAL WITH THESE SYSTEMS...WITH MODELS NOW
IN VERY GOOD AGREEMENT IN LIFTING THE CIRCULATION ACROSS CENTRAL
KANSAS BY SUNDAY EVENING. MOIST LOW LEVEL FLOW OFF OF THE WESTERN
GULF BECOMES BETTER ESTABLISHED LATER TONIGHT AND SUNDAY...WITH RAIN
DEVELOPING THROUGH THE LOWER MISSOURI VALLEY AND INTO WESTERN IL.
WITH SLOWER APPROACH HAVE TRIMMED BACK POPS TO JUST A SLGT CHANCE
ALONG/WEST OF ROUGHLY AN SQI-PNT LINE AFTER 21Z SUNDAY...WITH JUST
INCREASING CLOUDS DURING THE AFTERNOON AND THEN RAIN SPREADING
NORTH/NORTHEAST ACROSS THE REMAINDER OF THE CWA SUNDAY NIGHT. FAIRLY
DECENT FORCING COMING TOGETHER SUNDAY NIGHT WITH CONVERGENCE ALONG
LOW LEVEL OCCLUSION MOVING ACROSS THE CWA...HEIGHT FALLS IN ADVANCE
OF MID-LEVEL CIRCULATION...AND DIFFLUENT UPPER FLOW AHEAD OF
CYCLONICALLY CURVED UPPER JET STREAK ALL COMBINING TO PRODUCE FAIRLY
STRONG DEEP ASCENT ACROSS THE AREA SUNDAY NIGHT. FORECAST SOUNDINGS
DEVELOP A MOIST ADIABATIC THERMAL PROFILE THAT WHILE NOT
IMPRESSIVELY UNSTABLE...DOES EEK OUT ABOUT 100 J/KG IN SOME SPOTS
WHICH GIVEN DYNAMICS SUPPORTS THE INCLUSION OF AT LEAST A SLIGHT
CHANCE THUNDER MENTION. TEMP GUIDANCE IN GENERALLY GOOD AGREEMENT
FOR SUNDAY...THOUGH HAVE GONE A COUPLE OF DEGREES ABOVE MOS NUMBERS
ACROSS THE EAST WHERE MORE SUN IS LIKELY.

UPPER LOW CONTINUES TO LIFT NORTHEAST ACROSS WISCONSIN AND THE
EASTERN U.P. THROUGH MONDAY. RAIN SHOULD END FROM SOUTHWEST TO
NORTHEAST ACROSS THE CWA DURING THE MORNING AS THE MID-LEVEL DRY
SLOT WRAPS AROUND THE SOUTHERN PERIPHERY OF THE LOW. WHILE BEST DEEP
FORCING MOVES NORTHEAST OF THE CWA...MODELS INDICATE ANOTHER WEAK
VORT LOBE WHICH ROTATES ACROSS WI/NORTHERN IL DURING THE DAY WHICH
COMBINED WITH RELATIVELY WARM/MOIST LOW-LEVELS AND STEEPENING LAPSE
RATES ALOFT ACTUALLY RESULTS IN THE NAM-WRF DEVELOPING 600-1200 J/KG
OF MLCAPE ACROSS PARTS OF NORTHERN IL DURING THE AFTERNOON WITH
TRAILING FRONT WHICH MAY PROVIDE ENOUGH TRIGGER FOR THUNDERSTORM
CHANCES. IF STORMS DO OCCUR...IT WOULD APPEAR THAT THERE IS A
CONDITIONAL SEVERE THREAT...WITH STRONG 60-70 KT MID-LEVEL WINDS
SUPPLYING ENOUGH MAINLY UNIDIRECTIONAL SHEAR FOR A FEW STRONG
STORMS. BASED ON THIS HAVE ADDED CHANCE THUNDER TO THE NORTHERN
HALF OF THE CWA. SPC DAY 3 OUTLOOK AS INCLUDED A 5 PERCENT "SEE
TEXT" AREA FROM NORTHEAST IL/CHICAGO INTO LOWER MICHIGAN. SOUTHERN
PARTS OF THE CWA WOULD APPEAR TO BE WITHIN AN AREA OF STRONGER
CAPPING AT THIS TIME BASED ON FORECAST SOUNDINGS. PRECIP THREAT
LOOKS TO END BY MONDAY EVENING AS UPPER LOW CONTINUES OFF TO THE
NORTHEAST AND TRAILING COLD FRONT MOVES THROUGH. MONDAY LOOKS TO
BE A FAIRLY WARM DAY WITH RELATIVELY HIGH THETA-E LOW LEVEL AIR
ESPECIALLY ACROSS THE SOUTHEAST. HAVE BUMPED TEMPS UP TO THE LOWER
70S ACROSS THE SOUTHEAST HALF OR SO...BASED ON MODEL THERMAL
FIELDS AND THE POTENTIAL FOR A LITTLE MORE SUN.

HIGH PRESSURE DEVELOPS ACROSS THE AREA ON TUESDAY AS HEIGHTS RISE
BEHIND THE DEPARTING UPPER LOW...WITH THE FRONT PUSHING
SOUTH/SOUTHEAST OF THE CWA. WINDS VEER NORTHEAST AND EAST AS THE
HIGH MOVES THROUGH...PROVIDING COOLER BUT STILL UNSEASONABLY MILD
TEMPS. UPPER RIDGE THEN BUILDS QUICKLY AGAIN MID-WEEK WITH ANOTHER
STRONG STORM MOVING ACROSS CANADA. THIS SETS UP WARM AND MOIST SOUTH
LOW LEVEL FLOW AGAIN...WITH THE POTENTIAL FOR PERHAPS THE WARMEST
TEMPS YET. IN FACT THE ECMWF AND GFS BOTH HAVE SURFACE DEW POINT
TEMPS APPROACHING 60 DEGREES BY WEDNESDAY AFTERNOON. THIS ALSO WOULD
SUPPORT INCREASED CLOUD COVER AND THE POTENTIAL FOR SHOWERS AND
THUNDERSTORMS AHEAD OF A COLD FRONT WHICH APPROACHES WEDNESDAY
NIGHT...SO FOR NOW HAVE HELD TO LOWER 70S...BUT COULD PERHAPS
APPROACH OUR RECORD HIGHS WHICH ARE 74 AT ROCKFORD AND 77 AT CHICAGO
FOR MARCH 14TH.

.FIRE WEATHER...
1001 AM CDT

TEMPS HAVE WARMED A BIT SLOWER THAN ANTICIPATED SO FAR THIS
MORNING...BUT STILL THINK HIGH TEMPS WILL CLIMB INTO THE UPPER 50S
TO LOWER 60S. DEWPOINTS OVER MO/IA/WESTERN IL HAVE BEEN CREEPING
UP INTO THE 20S...BUT AS MIXING INCREASES WOULD EXPECT THAT TREND
TO LEVEL OFF AND MIN RH VALUES THIS AFTERNOON NEAR OR BELOW 25
PERCENT STILL APPEAR ON TARGET FOR MOST IF NOT ALL OF THE AREA.
WINDS ARE PICKING UP ON SCHEDULE AND STILL ANTICIPATE 20FT WINDS
AROUND 20MPH WITH GUSTS OVER 30 MPH. ALL INDICATIONS ARE THAT RED
FLAG WARNING AND PREVIOUS FIRE WEATHER FORECASTS ARE RIGHT ON
TRACK AND NO CHANGES PLANNED TO THE PREVIOUSLY ISSUED FORECASTS.

IZZI

546 AM CDT...
HAVE ELECTED TO UPGRADE FIRE WEATHER WATCH TO A WARNING THIS
MORNING. THE COMBINATION OF A STRONG PRESSURE GRADIENT...A WELL
MIXED BOUNDARY LAYER...AND VERY DRY LOWER TROPOSPHERIC MOISTURE
PROFILES WILL LEAD TO A HEIGHTENED WILD FIRE THREAT ACROSS
NORTHERN ILLINOIS AND NORTHWEST INDIANA TODAY. SUSTAINED 20 FOOT
WINDS ARE EXPECTED TO INCREASE TO 20 MPH BY LATE MORNING...WITH
GUSTS OF 35 TO 40 MPH ESPECIALLY ACROSS FAR NORTHERN. 10-HOUR DEAD
FUEL MOISTURE MEASUREMENTS FELL TO LESS THAN 10 PERCENT FRIDAY
AFTERNOON AT THE INDIANA DUNES AND MIDEWIEN TALLGRASS
PRAIRIE...AND ARE EXPECTED TO DO SO AGAIN WITH DRIER CONDITIONS
THIS AFTERNOON.

MODEL DEW POINT TEMPERATURES CONTINUE TO APPEAR TO BE OVER-FORECAST
BASED ON OBSERVED CONDITIONS...AND OBSERVED AND FORECAST SOUNDING
MOISTURE PROFILES FROM 00Z. HAVE UNDERCUT GUIDANCE DEW POINT TEMPS
SIGNIFICANTLY BASED ON MIXING TO OR SLIGHTLY ABOVE 900 MB...WHICH
COMBINED WITH FORECAST TEMPERATURES IN THE UPPER 50S TO LOWER 60S
YIELDS AFTERNOON MINIMUM RH VALUES OF 20-25 PERCENT. RED FLAG
CONDITIONS ARE EXPECTED TO CONTINUE THROUGH LATE AFTERNOON...AFTER
WHICH DECREASING WINDS...EVENING COOLING AND INCREASING RELATIVELY
HUMIDITY ARE EXPECTED.

MOVES OFF TO THE EAST. SOUTH/SOUTHEAST WINDS GENERALLY IN THE 10
KT RANGE AT MOST LOCATIONS BUT ONCE THE LOW LEVELS BEGIN TO MIX...
EXPECT GUSTS TO DEVELOP WITH THE POTENTIAL FOR GUSTS AS HIGH AS 30
KTS BY LATE MORNING. DEPENDING ON THE DEPTH OF MIXING THIS
AFTERNOON...EXPECT GUSTS IN THE 30-35 KT RANGE. GRADIENT BEGINS TO
WEAKEN LATER THIS AFTERNOON AND WITH SUNSET...EXPECT A STEADY DROP
OFF IN GUSTS FROM LATE AFTERNOON INTO EARLY THIS EVENING. WIND
DIRECTION SHOULD TURN SOUTH/SOUTHWEST BY MID/LATE MORNING AND

.MARINE...

311 AM...UPGRADED THE GALE WARNING TO A STORM WARNING FOR THE
NORTHERN HALF OF LAKE MICHIGAN.

A LARGE AREA OF HIGH PRESSURE EXTENDS FROM QUEBEC SOUTHWEST TO
TEXAS AND WILL MOVE EAST TODAY AS LOW PRESSURE MOVES ACROSS HUDSON
BAY THIS AFTERNOON/EVENING. THE GRADIENT WILL TIGHTEN QUICKLY AND
EXPECT WIND SPEEDS/GUSTS TO RAPIDLY INCREASE OVER THE NEXT SEVERAL
HOURS WITH SOUNDINGS SUGGESTING GUSTS AS HIGH AS 50 KT FOR A 3-6
HOUR PERIOD FROM MID MORNING INTO EARLY AFTERNOON OVER PARTS OF
NORTHERN LAKE MICHIGAN. MUCH WARMER AIR ALOFT BEGINS SPREADING
ACROSS THE LAKE DURING THE AFTERNOON WHICH PUSHES THE INVERSION
LOWER AND THUS SHRINKING THE MIXED LAYER AND EXPECT A STEADY
DECLINE IN WIND SPEEDS/GUSTS THROUGH THE AFTERNOON BUT GALES STILL
LIKELY INTO THE EVENING HRS. GRADIENT WILL CONTINUE TO SUPPORT 30
KTS OVERNIGHT AND THEN 20-25 KTS SUNDAY/SUNDAY NIGHT WITH SOME
HIGHER GUSTS POSSIBLE AT TIMES. ANOTHER STRONGER PERIOD OF
WINDS...30 KTS WITH PERHAPS SOME HIGHER GUSTS...POSSIBLE AGAIN ON
MONDAY. CMS
