AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHICAGO/ROMEOVILLE IL
242 PM CST THU FEB 18 2016
.SHORT TERM...
242 PM CST
THROUGH SATURDAY...
THE MAIN HIGHLIGHTS IN THE SHORT TERM WILL CONTINUE TO BE THE VERY
MILD CONDITIONS FRIDAY AND SATURDAY...ALONG WITH A PERIOD OF STRONG
WINDS ON FRIDAY. WE HAVE ISSUED A WIND ADVISORY FOR THE AREA FOR
FRIDAY.
SOUTHEASTERLY WINDS CONTINUE TO INCREASE ACROSS THE AREA THIS
AFTERNOON AS PRESSURE FALLS...ASSOCIATED WITH A STRONG AREA OF LOW
PRESSURE ACROSS THE NORTHERN HIGH PLAINS...CONTINUE TO OVERSPREAD
THE UPPER MIDWEST. THIS SHOULD CONTINUE TO BE THE TREND TONIGHT...AS
THESE STRONG PRESSURE FALLS OVERSPREAD THE UPPER GREAT LAKES REGION.
THE GUSTY WINDS TONIGHT WILL ALSO ALLOW TEMPERATURES TO BE ON THE
RISE OVERNIGHT...AND THIS WILL SET THE STAGE FOR NEAR RECORD HIGHS
ON FRIDAY.
NOT MUCH HAS CHANGED WITH THE THINKING OF THE WARM AND VERY WINDY
CONDITIONS FRIDAY. THE MAIN STORM SYSTEM IS EXPECTED TO SHIFT
EASTWARD ALONG THE OR NEAR THE CANADIAN BOARDER THROUGH FRIDAY
EVENING. A THERMAL RIDGE...FEATURING 925 MB TEMPERATURES AROUND 12
DEGREES C...WILL ADVECT OVER THE AREA RIGHT OFF THE CENTRAL HIGH
PLAINS BY MIDDAY FRIDAY...JUST PRIOR TO THE ARRIVAL OF A PACIFIC
COLD FRONTAL PASSAGE. THIS LOOKS TO SUPPORT SURFACE TEMPERATURES
AROUND 60 NORTH...TO THE MID 60S SOUTH. STRONG SOUTHERLY
WINDS...GUSTING UP INTO THE LOW 30 KT RANGE EARLY FRIDAY WILL LIKELY
INCREASE SUBSTANTIALLY FOR A PERIOD BY LATE MORNING AND INTO THE
AFTERNOON AS A COLD FRONTAL TROUGH PUSHES ACROSS THE AREA. STRONG
PRESSURE RISES IN THE WAKE OF THIS FRONTAL TROUGH WILL LIKELY LEAD
TO A PERIOD OF EFFICIENT ATMOSPHERIC MIXING. GIVEN THAT THE WIND
FIELD OFF THE SURFACE WILL BE FEATURING WINDS IN EXCESS OF 50 KT
AROUND 900 MB FRIDAY AFTERNOON...IT IS POSSIBLE THAT SOME GUSTS
AROUND MIDDAY/EARLY AFTERNOON COULD APPROACH 45 KT. BECAUSE OF
THIS...WE HAVE OPTED TO ISSUE A WIND ADVISORY FROM MID MORNING
THROUGH THE AFTERNOON FRIDAY FOR WIND GUSTS UP TO 50 MPH.
WIND SPEEDS SHOULD EASE FRIDAY EVENING. THE MAIN CHANGE IN AIRMASS
BEHIND THIS FRONT SHOULD BE LOWER DEWPOINTS...WITH NOT MUCH COOLER
AIR EXPECTED IN ITS WAKE. BECAUSE OF THIS...IT LOOKS LIKE SATURDAY
WILL ALSO BE A MILD DAY...WITH TEMPERATURES AGAIN WELL INTO THE 50S
TO NEAR 60...AND WITH LIGHTER WINDS.
KJB
&&
.LONG TERM...
256 AM CST
MONDAY THROUGH WEDNESDAY...
WEST COAST UPPER RIDGE RE-ESTABLISHES MONDAY-TUESDAY INDUCING A
BROAD DOWNSTREAM UPPER TROUGH ACROSS THE EASTERN 2/3 OF THE CONUS
DURING THE EXTENDED FORECAST PERIOD. AT THE SURFACE...COLDER HIGH
PRESSURE SPREADS ACROSS THE UPPER MIDWEST AND GREAT LAKES REGION
SUNDAY NIGHT AND MONDAY...WITH COOLER NORTH-NORTHEAST WINDS
BRINGING MORE SEASONABLE TEMPS TO THE REGION EARLY NEXT WEEK.
WHILE THAT PATTERN LOOKS TO HOLD FOR MUCH OF NEXT WEEK THERES
NOTHING TOO TERRIBLE FOR LATE FEBRUARY...WITH HIGHS IN THE 30S AND
LOWS IN THE 20S. NO SIGNIFICANT PRECIP EVENTS CURRENTLY IN THE
PICTURE EITHER.
RATZER
&&
.AVIATION...
FOR THE 18Z TAFS...
MAIN CONCERNS FOR AVIATION WILL BE ON POTENTIAL FOR LLWS LATE
TONIGHT THROUGH DAYBREAK...THEN VERY GUSTY WINDS THROUGH THE DAY
FRIDAY.
SOUTHEAST WINDS WILL CONTINUE TO INCREASE THIS AFTERNOON WITH
GUSTS DEVELOPING...ONCE THE MID LVL CLOUDS LIFT NORTHEAST OF THE
AIRFIELDS. THIS SHOULD RESULT IN GUSTS THIS AFTERNOON THROUGH
TONIGHT BETWEEN 20-28KT SLOWLY TURNING SOUTHERLY THEN
SOUTHWESTERLY BY DAYBREAK FRI. MOST OF THE CLOUD BASES WILL RANGE
FROM 4-5KFT AGL...SO EXPECT VFR CONDS TO PREVAIL. BUT THE MAIN
CONCERN WILL CONTINUE TO BE ON THE WINDS AND LLWS AT 2KFT AGL
TONIGHT APPROACHING 60KTS.
SHORTLY AFTER DAYBREAK FRIDAY MIXING WILL QUICKLY INCREASE AND
ALLOW GUSTS TO NEAR 30-33KT BY 15Z...THEN INCREASE FURTHER BY
MIDDAY TOWARDS 40KT AND POSSIBLY A FEW GUSTS IN THE 40-44KT RANGE
AFTER 18Z FRI THROUGH 23Z.
BEACHLER
&&
.MARINE...
203 PM CST
PERSISTENT SOUTHEAST TO SOUTH WINDS GUSTING TO AROUND 20 KTS
THIS AFTERNOON...OR CLOSER TO 30 KTS FOR TALLER VESSELS...WILL
INCREASE IN SPEED OVERNIGHT INTO TOMORROW. WITH MILD WINDS OVER THE
STABLE MARINE LAYER IT IS NOT CLEAR EXACTLY HOW STRONG THE WINDS AND
GUSTS WILL GET TOMORROW...BUT A PROLONGED PERIOD OF SOLID SOUTHERLY
GALES IS QUITE LIKELY. BRIEF AND ISOLATED STORM FORCE GUSTS ARE NOT
OUT OF THE QUESTION.
A COLD FRONT MOVING THROUGH LATER FRIDAY WILL VEER WINDS WESTERLY
FOR FRIDAY NIGHT AND SATURDAY...THEN EVENTUALLY TO NORTH BY
SUNDAY...WHILE SPEEDS VERY GRADUALLY DIMINISH.
