AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHICAGO/ROMEOVILLE IL
319 AM CST SUN FEB 26 2012
.DISCUSSION...
317 PM...MAIN FORECAST CONCERNS THROUGH MONDAY ARE TEMPERATURES
AS WELL AS WINDS SUNDAY AS A STORM SYSTEM PASSES NORTH OF THE
AREA. ANOTHER STORM SYSTEM WILL AFFECT THE AREA...AS WELL AS MUCH
OF THE LAKES REGION...MID WEEK.
A BELOW NORMAL DAY TODAY AS TEMPERATURES HAVE STRUGGLED INTO THE
LOWER 30S AWAY FROM THE SNOW PACK...AND HAVE ONLY REACHED THE MID
TO UPPER 20S OVER THE SNOW. WESTERLY WINDS GUSTING 25-30 MPH AT
TIMES MADE IT FEEL EVEN COLDER WITH WIND CHILLS IN THE TEENS. A
RIDGE OF HIGH PRESSURE WILL MOVE ACROSS THE AREA THIS EVENING.
WINDS WILL BECOME LIGHT AND VRB OR EVEN CALM FOR A FEW HRS AND
WITH CLEAR SKIES THIS SHOULD ALLOW ALREADY COLD TEMPS TO DROP
QUICKLY THIS EVENING. LOWS OVER THE SNOW PACK COULD EASILY DROP
INTO THE LOWER TEENS AND PERHAPS EVEN SINGLE DIGITS. HOWEVER...
AS THE RIDGE MOVES EAST OVERNIGHT...STRONG WARM AIR ADVECTION
WILL LIKELY ALLOW TEMPS TO BEGIN WARMING OVERNIGHT AND COULD
POTENTIALLY WARM 6 TO 10 DEGREES BY MORNING. TEMPS WILL CONTINUE
WARMING SUNDAY AS THE LOW LEVELS BEGIN TO MIX. SOUTH OF THE
SNOWPACK...EXPECT TEMPS TO EASILY REACH THE UPPER 40S TO LOWER
50S. GIVEN A LACK OF HIGHER DEWPOINTS/RETURN OF LOW LEVEL
MOISTURE...RATHER UNCERTAIN AS TO HOW WARM TEMPS WILL CLIMB
OVER THE SNOW AND HAVE GONE GENERALLY WITH LOWER 40S.
LOW PRESSURE WILL MOVE ACROSS THE UPPER MIDWEST AND NORTHERN
LAKES LATE TONIGHT AND SUNDAY. AS IT APPROACHES...THE GRADIENT
WILL RAPIDLY TIGHTEN SUNDAY MORNING AND EXPECT WINDS TO QUICKLY
INCREASE AFTER SUNRISE AND BE GUSTING AS HIGH AS 40 MPH BY MID
MORNING AND CONTINUE AT THOSE SPEEDS INTO EARLY AFTERNOON BEFORE
DIMINISHING MID/LATE AFTERNOON. WHILE IT APPEARS WINDS WILL REMAIN
BELOW ADVISORY CRITERIA...THIS WILL NEED TO BE MONITORED. THIS LOW
WEAKENS AS IT LIFTS NORTHEAST SUNDAY NIGHT. THE BULK OF THE PRECIP
WITH THIS SYSTEM WILL REMAIN WELL NORTH OF THE CWA. A TRAILING
COLD FRONT WILL MOVE ACROSS THE AREA LATE SUNDAY NIGHT INTO MONDAY
MORNING WITH ANOTHER RIDGE OF HIGH PRESSURE MOVING ACROSS THE
LAKES REGION MONDAY AFTERNOON/EVENING. STILL EXPECT COOLING
AFFECTS ON HIGHS MONDAY OVER THE SNOW PACK AND HAVE LOWERED HIGHS
THERE ONLY INTO THE 30S.
MODELS APPEAR QUITE DIFFERENT THAN 24 HRS AGO REGARDING THE NEXT
STORM SYSTEM TO AFFECT THE REGION TUESDAY INTO WEDNESDAY NIGHT.
WHILE THE LOW IS STILL QUITE STRONG OVER THE CENTRAL PLAINS...IT
WEAKENS AND SLOWS AS IT MOVES EAST WITH THE ECMWF EVEN SLOWER THAN
THE GFS. THIS LOWERS CONFIDENCE REGARDING TO THE ONSET OF PRECIP.
WITH A MORE SOUTHERN TRACK OF THE LOW...PRECIP TYPE BECOMES AN
ISSUE AS WELL THOUGH IT STILL LOOKS WARM ENOUGH FOR MAINLY RAIN
UNTIL THE LOW PASSES...SOMEWHAT SIMILAR TO THIS PAST STORM
THURSDAY NIGHT INTO FRIDAY. TRENDED POPS LOWER TUESDAY BUT OVERALL
DIDN/T MAKE MANY CHANGES DURING THIS TIME PERIOD AND ALSO
MAINTAINED THE CHANCE OF THUNDER SINCE ITS ALREADY MENTIONED.
THOUGH A CONTINUED SOUTHERN TRACK OF THIS SYSTEM WOULD LIKELY PUSH
THE THUNDER THREAT FURTHER SOUTH. OF NOTE HOWEVER...IS THERE DOES
SEEM TO BE CONSENSUS OF A BAND OF LIGHT SNOW ON THE BACK SIDE OF
THIS SYSTEM AND THE POTENTIAL FOR SOME ACCUMULATION...AT LEAST
ACROSS FAR NORTHERN IL...WILL NEED TO BE WATCHED AS THIS SYSTEM
EVOLVES. CMS
&&
.AVIATION...
//ORD AND MDW CONCERNS...UPDATED 09Z...
* SOUTH WINDS GUSTING NEAR/ABOVE 30 KTS BY LATE SUNDAY
MORNING...WITH SOME CHANCE FOR 35-40 KT GUSTS EARLY AFTERNOON.
* SOUTHWEST WINDS AT 1500-3000 FT AGL UP TO OR IN EXCESS OF 50 KT
FOR A BRIEF PERIOD SUNDAY MORNING INTO EARLY SUNDAY AFTERNOON
MAY PRODUCE LOW LEVEL WIND SHEAR OR COMPRESSION ISSUES.
MDB
//DISCUSSION...UPDATED 06Z...
DEEP LOW PRESSURE WILL TRACK FROM THE NORTHERN PLAINS THROUGH THE
UPPER MIDWEST AND NORTHERN LAKES THROUGH SUNDAY EVENING. WHILE THE
AIR ACROSS THE REGION IS VERY DRY...AND WILL NOT PRODUCE MUCH IN
THE WAY OF CLOUD COVER ACROSS THE FORECAST AREA...STRONG SOUTH
WINDS ARE EXPECTED TO DEVELOP AS THE PRESSURE GRADIENT TIGHTENS
EARLY SUNDAY IN RESPONSE TO THE LOW. MODEL FORECASTS INDICATE THAT
SUSTAINED SPEEDS WILL RAMP UP QUICKLY SUNDAY MORNING AS THE LOW
MOVES INTO MINNESOTA...WITH SUSTAINED SOUTH WIND SPEEDS APPROACHING
20 KTS THROUGH THE MIDDAY HOURS. MODEL FORECAST SOUNDINGS EXHIBIT
SOME DIFFERENCES WITH HOW DEEPLY MIXED THE BOUNDARY LAYER
BECOMES...BUT WITH BARE GROUND UPSTREAM TO THE SOUTH WOULD EXPECT
LOW LEVELS WOULD MIX SUFFICIENTLY TO PRODUCE GUSTS TO 30-35 KTS OR
PERHAPS EVEN A LITTLE HIGHER FROM LATE MORNING INTO THE EARLY
AFTERNOON HOURS. EXCEPTION MAY BE AT KRFD...WHERE RECENT SNOW
COVER EXTENDING SOUTH OF THE TERMINAL MAY KEEP THE MIXED LAYER
MORE SHALLOW DUE TO COOLER SNOW-COVERED GROUND TEMPERATURES.
WINDS IN THE 1500-3000 FT AGL LAYER WILL INCREASE INTO THE 50-60
KT RANGE AS THE LOW LEVEL INFLOW JET ASSOCIATED WITH THE DEEP LOW
SPREADS ACROSS THE AREA DURING THE LATE MORNING TO EARLY AFTERNOON
HOURS. THIS MAY SETUP A PERIOD OF NON-CONVECTIVE LOW LEVEL WIND
SHEAR AT KRFD...WHERE THESE STRONGER WINDS ALOFT WILL ARRIVE
SOONER...THOUGH ACROSS THE CHICAGO AREA TERMINALS IT APPEARS THAT
SURFACE WINDS WILL BE GUSTING AND PRODUCING MECHANICAL MIXING AND
TURBULENCE THAT WOULD PRECLUDE THE SHARPER CHANGE IN WIND SPEED
WITHIN A SHALLOW DEPTH.
WINDS WILL START THE DAY SOUTH-SOUTHEAST...GRADUALLY VEERING MORE
SOUTH-SOUTHWEST INTO THE AFTERNOON...AND EVENTUALLY MORE WEST-
SOUTHWEST BY SUNDAY EVENING. WINDS WILL DIMINISH BUT WILL LIKELY
REMAIN SOMEWHAT GUSTY INTO THE EARLY EVENING HOURS.
OTHERWISE...VFR CONDITIONS EXPECTED THROUGHOUT THE PERIOD...WITH
VERY DRY AIRMASS IN PLACE ACROSS THE MIDWEST IN ADVANCE OF THIS
STORM SYSTEM. PATCHY MID/HIGH CLOUDS ARE ABOUT ALL THAT IS
ANTICIPATED.
RATZER
//ORD AND MDW CONFIDENCE...UPDATED 09Z...
* HIGH CONFIDENCE IN WIND TRENDS THROUGH EARLY SUNDAY MORNING.
* MODERATE CONFIDENCE ON WIND GUST SPEEDS SUNDAY.
* HIGH CONFIDENCE OF 1500-3000 FT AGL WINDS IN EXCESS OF 50 KTS
SUNDAY MORNING INTO EARLY AFTERNOON.
MDB/RATZER

MONDAY...VFR.
TUESDAY...CHANCE OF RAIN...POSSIBLE MVFR. CHANCE TSRA TUES NGT.

.MARINE...
315 AM CST
SEVERAL OPPORTUNITIES FOR GALES LIE AHEAD THIS FORECAST PERIOD WITH
HIGH CONFIDENCE IN THE FIRST ROUND TODAY WITH LOWER CONFIDENCE IN
ANOTHER ROUND MONDAY AND AGAIN AT SOME POINT FROM LATER TUESDAY
THROUGH EARLY THURSDAY.
HIGH PRESSURE ACROSS THE OHIO VALLEY AND EASTERN GREAT LAKES THIS
MORNING WILL MOVE EASTWARD AS LOW PRESSURE OVER THE CENTRAL AND
NORTHERN HIGH PLAINS MOVES INTO SOUTHERN MINNESOTA AND THEN THE U.P.
OF MICHIGAN INTO THIS EVENING. THE PRESSURE GRADIENT WILL TIGHTEN
CONSIDERABLY THIS MORNING AS LOW LEVEL WINDS INCREASE DRAMATICALLY.
WARMER AIR WILL BE MOVING IN ALOFT BUT IT WILL STILL BE COOL ENOUGH
TO ALLOW FOR MIXING OVER LAKE MICHIGAN. EXPECT THAT SOUTH TO
SOUTHEAST WINDS WILL INCREASE TO GALE FORCE BY MID MORNING AND
CONTINUE INTO EARLY THIS EVENING THOUGH WINDS SHOULD EASE BELOW
GALES FOR THE IL/IN NEARSHORE WATERS BY EVENING AS THE GRADIENT
RELAXES. ANOTHER LOW LEVEL SPEED MAX WILL CROSS THE SOUTHERN PART
OF THE LAKE THIS EVENING WHICH IS RAISING CONCERNS FOR GALES GOING
A BIT LONGER. WILL CONTINUE WITH GALE WARNING UNTIL MID EVENING
FOR NOW BUT MENTION POTENTIAL FOR SOME GALE FORCE GUSTS THROUGH
THE EVENING AND THE POSSIBILITY OF EXTENDING THE WARNING A BIT
LONGER. COLDER AIR WILL SPREAD IN BEHIND A COLD FRONT TONIGHT AS
WINDS TURN WESTERLY THEN NORTHWESTERLY. THERE MAY BE ANOTHER
PERIOD WHERE GALES RETURN EARLY MONDAY MORNING BUT THESE WOULD
LIKELY BE SHORT LIVED WITH WINDS DIMINISHING MONDAY AFTERNOON AS
STRONG HIGH PRESSURE ARRIVES FROM THE WEST.
THE HIGH WILL QUICKLY MOVE ACROSS THE LAKE MONDAY NIGHT WHILE
ANOTHER LOW PRESSURE SYSTEM TAKES SHAPE OVER THE CENTRAL HIGH
PLAINS. THIS LOW WILL TRACK EAST-NORTHEAST TOWARDS CENTRAL/SOUTHERN
WISCONSIN BY WEDNESDAY AFTERNOON/EVENING. THE PRESSURE GRADIENT
TIGHTENS SIGNIFICANTLY AHEAD OF THIS LOW WITH SOUTHEAST TO EAST
WINDS INCREASING. MID TO EVEN HIGH RANGE GALES LOOK LIKE AT LEAST
A SMALL POSSIBILITY EARLY/MID MORNING WEDNESDAY. GUST POTENTIAL
FORECAST WILL BE TOUGH GIVEN THAT STRONG WARM ADVECTION WILL REACH
SOUTHERN REACHES OF THE LAKE WHILE NORTHERN AREAS LOOK TO REMAIN
COLD ENOUGH FOR OVER WATER MIXING TO OCCUR. THE LOW WILL THEN
CROSS THE LAKE WEDNESDAY AFTERNOON WITH A PERIOD OF ELEVATED WINDS
IMMEDIATELY BEHIND IT WEDNESDAY NIGHT BEFORE ANOTHER AREA OF HIGH
PRESSURE MOVES IN AND QUIETS THINGS DOWN FOR THURSDAY.
