Area forecast discussion, May 31, 9:57 PM CST, 2 hours 3 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE CHICAGO/ROMEOVILLE IL 1057 PM CDT MON MAY 31 2010 .DISCUSSION... 307 PM CDT LATEST RUC ANALYSIS AND VIS/IR/WV/RADAR IMAGERY SHOW A COOL FRONT SLOWLY MOVING TO THE SOUTHEAST FROM SAGINAW BAY TO ST. LOUIS. HEAVIEST LINE OF THUNDERSTORMS HAVE PUSHED TO THE SOUTHEAST OF THE FORECAST AREA...WITH A STRATIFORM WITH EMBEDDED THUNDER AREA STRETCHING FROM MIDWAY TO PONTIAC. ADDITIONAL SHOWER AND THUNDERSTORM ACTIVITY HAS DEVELOPED WELL BEHIND THE FRONT NEAR ROCKFORD WHERE SOME SURFACE INSTABILITY IS LINGERING...JUST AHEAD OF A DRY AIR SURGE FROM THE NORTHWEST. PRECIP COVERAGE IS THE MAIN FORECAST CONCERN THROUGH THIS EVENING...BEFORE THE ATTENTION TURNS TO THUNDERSTORM CHANCES TUESDAY NIGHT THROUGH THE END OF THE WEEK. TONIGHT AND TUESDAY...THE COOL FRONT WILL CONTINUE TO SLIDE TO THE SOUTHEAST WHILE BECOMING MORE AND MORE ILL-DEFINED. MODELS STILL INDICATE SOME INSTABILITY LEFT OVER OVER THE SE FORECAST AREA EARLY THIS EVENING WHICH COULD CREATE A FEW STORMS...THOUGH RADAR IMAGERY SUGGESTS PRECIP SHOULD BE OVER BY THEN. WILL CONTINUE TO LEAVE A SMALL MENTION THROUGH MID-EVENING...WHICH LINES UP WITH OFFICES TO THE EAST. DRIER AIR BEHIND THE FRONT WILL FINALLY MAKE PROGRESS INTO THE AREA LATE THIS EVENING INTO THE OVERNIGHT HOURS. SHORTWAVE OVER THE PLAINS IS PROGGED TO SLIDE TO NORTH WHICH WILL PRESERVE THE CLEARING TREND. WITH ALL THE RAINFALL...CLEARING SKIES...AND LIGHT WINDS...POSSIBILITY EXISTS FOR SOME FOG TOMORROW MORNING. DEWPOINTS UPSTREAM ARE IN THE 40S TO LOW 50S...AND SOME OF THIS DRIER AIR SHOULD WORK INTO AT LEAST THE NW HALF OF THE FORECAST AREA. WILL THROW IN AREAS OF FOG FOR THE SOUTHEAST HALF WHERE ALL THE RAIN FELL. HIGH PRESSURE IN THE MORNING WILL DRIFT TO THE EAST WHICH WILL ALLOW MUGGIER AIR TO RETURN BY THE AFTERNOON VIA SOUTHWEST WINDS. DEEPER MOISTURE WILL REMAIN TO THE WEST...HOWEVER. TEMPS IN THE LOW TO MID 80S AWAY FROM LAKE MICHIGAN. TUESDAY NIGHT THROUGH WEDNESDAY NIGHT...ACTIVE PATTERN BEGINS TUESDAY NIGHT WHEN RETURN FLOW AHEAD OF LOW PRESSURE OVER THE CENTRAL PLAINS CRANKS UP...LEADING TO LLJ DEVELOPMENT ACROSS IOWA/NEBRASKA. AT THE SAME TIME...SHORTWAVE MOVING ACROSS ONTARIO WILL BE PUSHING A COLD FRONT SOUTHWARD ACROSS MINNESOTA AND WISCONSIN. PLENTY OF CONVERGENCE WILL OCCUR BETWEEN THESE TWO FEATURES IN COMBINATION WITH DIVERGENCE ALOFT IN THE RIGHT ENTRANCE REGION OF A JET STREAK TO SUPPORT MCS DEVELOPMENT TUESDAY EVENING. WITH WESTERLY FLOW ALOFT...CONVECTION THAT DEVELOPS UPSTREAM OVER IOWA/NEBRASKA WILL LIKELY PUSH INTO THE FORECAST AREA LATE. HARD TO GAUGE ELEVATED INSTABILITY WITH SOME CONVECTIVE FEEDBACK IN THE MODELS...BUT ENOUGH VERTICAL SHEAR (30-40KTS) APPEARS TO BE PRESENT FOR POTENTIAL BOW ECHOS WITH ISOLATED DAMAGING WINDS AND LARGE HAIL ALONG WITH HEAVY RAINFALL. NOCTURNAL CONVECTION PUSHES EAST/WEAKENS WEDNESDAY MORNING. HOWEVER...OUTFLOW BOUNDARIES ALONG WITH THE SYNOPTIC FRONT DROPPING IN FROM THE NORTH WILL PROVIDE THE FOCUS FOR CONTINUING THUNDERSTORM DEVELOPMENT WITHIN A BROAD WARM ADVECTION REGIME SOUTH OF THE BAROCLINIC ZONE. 500MB WINDS ARE STRONGEST BEHIND THE FRONT...BUT 25-30KTS OF DEEP LAYER SHEAR WILL BE SUPPORTIVE FOR LOW END SEVERE CHANCES FOR MUCH OF THE DAY WITHIN THE WARM SECTOR. SHORTWAVE TROUGH THEN PROGRESSES ACROSS THE PLAINS SENDING A SURFACE LOW ALONG THE BAROCLINIC ZONE. WHERE THIS LOW TRACKS IS UP FOR DEBATE (UNCERTAINTY OF WHICH EXTENDS INTO THURSDAY) AND MAY DEPEND ON HOW FAR SOUTH OUTFLOW PUSHES THE FRONT TO THE SOUTH. WILL CONTINUE THE HIGH CHANCE POPS INTO WEDNESDAY NIGHT. THURSDAY THROUGH SUNDAY...NO BIG CHANGES IN MODEL PREFERENCE THIS MORNING FOR THE EXTENDED PORTION OF THE FORECAST...AS HPC STICKS WITH THE ECMWF. HOWEVER...ZONAL FLOW WILL BE PREVALENT MAKING IT DIFFICULT TO TIME INDIVIDUAL SHORTWAVES MOVING WITHIN THE FAST FLOW ALOFT. AS A RESULT CONTINUITY ISNT THE BEST FRIDAY ONWARD...SO WILL TRY TO BLEND IN SOME GFS ENSEMBLE IDEAS. STILL SOME MODEL DISCREPANCIES FOR THE TRACK OF A LOW PRESSURE SYSTEM ACROSS THE SOUTHERN GREAT LAKES ON THURSDAY. THE 00Z ECMWF IS THE LONE STALWART FOR A NORTHERLY TRACK...POSSIBLY OWING TO ITS SLOWER TIMING OF THE SHORTWAVE APPROACHING THE REGION. WILL BLEND THE SOUTHERLY AND NORTHERLY TRACKS WHICH KEEPS DECENT CONTINUITY WITH THE PREVIOUS FORECAST. IN ANY CASE...ACTIVE WEATHER WILL CONTINUE ON THURSDAY WITH THE PASSAGE OF THE LOW PRESSURE SYSTEM. CONVECTION/MCS POSSIBILITIES DEPENDS ON THE TRACK AND RESULTANT LOCATION OF INSTABILITY...WHICH CANNOT REALLY BE DETERMINED YET. CONDITIONS DRY OUT THURSDAY NIGHT AND FRIDAY WITH HIGH PRESSURE OVER THE AREA. NEXT WAVE POTENTIALLY ARRIVES LATE FRIDAY NIGHT INTO SATURDAY WITH A VIGOROUS JET STREAM APPROACHING FROM THE NORTHWEST. WILL DRY THINGS OUT SUNDAY BEHIND THE SYSTEM WITH COOLER/LESS HUMID AIR RETURNING. MPC && .AVIATION... //ORD AND MDW CONCERNS...UPDATED 04Z... CONCERNS REMAIN FOG OVERNIGHT INTO THE DAWN HOURS DUE TO LIGHT AND VARIABLE WINDS AND A NEAR-SATURATED BOUNDARY LAYER FROM EARLIER RAIN. MVFR FOG IS ALREADY BEING OBSERVED AT SEVERAL AREA AIRPORTS. CONDITIONS FAVOR GENERAL DETERIORATION IN VISIBILITIES. LINGERING STRATUS HANGING ON JUST SOUTH OF MDW TOWARDS GYY...WHICH SHOULD TAKE THE TREND OF THE PAST COUPLE HOURS AND SHIFT SLIGHTLY SOUTH. FOG STILL APPEARS TO BE THE DOMINANT PLAYER OVERNIGHT...BUT SOME OF THE STRATUS MAY ABATE THE LOWER VISIBILITIES FOR A WHILE...AND/OR MAKE IT TEMPORARY AT TIMES AT MDW. GIVEN THE VISIBILITY TRENDS...LIFR FOG IS TEMPORARILY POSSIBLE AT MDW BETWEEN 09Z AND 12Z. MTF //DISCUSSION...UPDATED 00Z... THE PRIMARY FRONT IS NOW WELL TO THE SOUTHEAST OF THE TERMINALS...WITH THE SECONDARY FRONT PROVIDING THE WIND SHIFT STRETCHED FROM FAR SOUTHEAST WI TO NEAR PEORIA. THIS WILL NOT PROGRESS MUCH FURTHER SOUTHEAST BEFORE LOSING DEFINITION THIS EVENING. THIS WILL YIELD LIGHT AND VARIABLE WINDS...AT TIMES CALM...FROM MID-EVENING TO DAYBREAK AT THE TAF SITES. GIVEN THE RAIN-MOISTENED BOUNDARY LAYER...FOG IS PROBABLE...ESPECIALLY WHEN CONSIDERING A 40 YEAR CONDITIONAL CLIMATOLOGY GOING INTO THE NIGHTTIME HOURS. THE CURRENT SMALL TEMPERATURE/DEW POINT SPREADS AT MDW AND GYY FAVOR A NEARLY 80 PERCENT CHANCE OF MVFR FOG FOR THE OVERNIGHT HOURS...AND 30 TO 40 PERCENT CHANCE OF IFR. FOR IFR VISIBILITY...THIS PROBABILITY IS AROUND FIVE TIMES HIGHER THAN CLIMATOLOGY FOR A MAY AND JUNE EARLY MORNING. SO HAVE INCLUDED IFR FOG MENTION. OTHER SITES ARE MORE PROBABLE TO SEE MVFR. THE LINGERING STRATUS IN THE WAKE OF THE RAIN FROM MDW THROUGH NORTHWEST INDIANA SHOULD GRADUALLY FADE DURING THE EARLY TO MID EVENING...WITH THE HYDROLAPSE STRONGLY FAVORING FOG OVERNIGHT. IT IS POSSIBLE SOME STRATUS LINGERS NEAR GYY THROUGH THE ENTIRE NIGHT. A DEVELOPING FRONTAL SYSTEM WILL MOVE FROM THE PLAINS STATES TOWARDS THE MISSISSIPPI VALLEY LATER ON TUESDAY...WHICH OUTSIDE OF THE LAKE BREEZE INFLUENCE WILL CREATE SOUTHERLY WINDS. ON A PRE- FRONTAL DAY ON SUNDAY THE LAKE BREEZE DID MAKE IT THROUGH MDW...BUT THAT WAS A WARMER DAY THAN FORECAST ON TUESDAY...SO WILL KEEP THE LAKE BREEZE SHY OF ORD AND MDW...BUT BRING THROUGH GYY. MTF //ORD AND MDW CONFIDENCE...UPDATED 04Z... CONFIDENCE IN OVERNIGHT SUSTAINED MVFR FOG IS HIGH AT BOTH AIRPORTS. CONFIDENCE IN IFR FOG FOR SEVERAL HOURS AT MDW IS HIGH...WHILE IT REMAINS LOW FOR ORD. THE AMOUNT OF LOW CLOUDS IN THE MDW TAF HAS MODERATE CONFIDENCE. MTF //OUTLOOK FOR ORD/MDW FOR 06Z WEDNESDAY-12Z SUNDAY...UPDATED 00Z... TUESDAY NIGHT...A CHANCE OF TSRA LATE. MVFR POSSIBLE WITH PRECIP. WEDNESDAY...CHANCE OF TSRA AFTERNOON AND NIGHT. MVFR POSSIBLE. THURSDAY...CHANCE OF TSRA DURING THE DAY. MVFR POSSIBLE. FRIDAY...CHANCE OF TSRA. SATURDAY...CHANCE OF TSRA. SUNDAY...VFR. MTF && .MARINE... 101 PM CDT A COLD FRONT WILL CONTINUE TO CROSS SOUTHERN LAKE MICHIGAN THIS AFTERNOON. THIS FRONT WILL BE THE FOCUS FOR THUNDERSTORM DEVELOPMENT THE REMAINDER OF THIS AFTERNOON. SOME OF THESE STORMS MAY PRODUCE BRIEF WIND GUSTS TO 40KT. A RIDGE OF HIGH PRESSURE WILL BUILD ACROSS THE WESTERN GREAT LAKES TONIGHT...AND WILL PASS ACROSS LAKE MICHIGAN TUESDAY MORNING. THIS WILL BRING CLEARING SKIES THIS EVENING ALONG WITH LIGHT NORTH TO NORTHWEST WINDS. ANOTHER STORM SYSTEM WILL BE TAKING SHAPE OVER WESTERN KANSAS BY TUESDAY EVENING. THIS LOW IS FORECAST TO TRACK NORTHEASTWARD TOWARD THE SOUTHERN GREAT LAKES BY WEDNESDAY...BRINGING MORE THUNDERSTORMS ACROSS LAKE MICHIGAN AS EARLY AS TUESDAY NIGHT.
