Area forecast discussion, Jun 18, 10:10 PM CDT, 2 hours 10 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE CHICAGO/ROMEOVILLE IL 1010 PM CDT WED JUN 18 2014 .DISCUSSION... 301 PM CDT SYNOPSIS...THE UNSTABLE PATTERN CONTINUES WITH MULTIPLE PERIODS OF THUNDERSTORMS POSSIBLE. TEMPERATURES WILL BE CLOSELY TIED TO THUNDERSTORM DEVELOPMENT AS WE SAW TODAY. HAVE 80S TO 90S FOR THE REST OF THIS WEEK THEN FINALLY COOLING INTO THE LOWER 80S NEXT WEEK. REST OF TODAY THROUGH FRIDAY NIGHT... OVERALL CONFIDENCE IS LOW IN THE FORECAST. NONE OF THE GUIDANCE MEMBERS HANDLED THIS MORNING/S CONVECTION WELL SO THE MODELS RUNS ARE SUSPECT. DID NOT WANT TO MAKE MAJOR CHANGES TO THE FORECAST SO BACKED OFF ON POPS AND TEMPS IN REASONABLE PLACES. AN UPPER LEVEL SHORTWAVE IS MOVING OVER SOUTHERN WI WITH RIDGING SETTING UP RIGHT BEHIND IT. THE RIDGE WILL SIT OVER THE REGION THROUGH THURSDAY NIGHT. AT THE SURFACE A LOW IS OVER NEBRASKA AND A BOUNDARY STRETCHES FROM MUSCATINE IOWA TO LINCOLN ILLINOIS TO LAFAYETTE INDIANA. CLOUD COVER REMAINS THICK OVER THE REGION AND TEMPERATURES ARE STRUGGLING TO WARM. WE ARE ALSO VERY STABLE SO EXPECTING ANY FURTHER SHOWER OR THUNDERSTORM DEVELOPMENT TO OCCUR OVER WI AND/OR IA WHERE THEY HAVE HAD BETTER RECOVERY FROM THIS MORNINGS CONVECTION. A STRAY SHOWER MAY SINK SOUTH INTO FAR NORTHERN IL BUT IN GENERAL THINKING THE REST OF THIS AFTERNOON SHOULD BE RELATIVELY QUIET. MAY SEE SOME STORMS TONIGHT WITH THE BOUNDARY AND SHORTWAVE IN THE REGION. HOWEVER BACKED OFF ON POPS DUE TO HOW STABLE WE ARE RIGHT NOW. I AM PROBABLY STILL TOO HIGH WITH POPS TONIGHT BUT DECIDED TO BACK OFF SLOWLY. ALSO LOWERED LOWS BY A FEW DEGREES SINCE MOST PLACES NORTH OF I-80 WILL LIKELY NOT GET OUT OF THE LOWER 80S THIS AFTERNOON. THE RIDGE MOVES OVERHEAD TOMORROW BUT THE PLAIN/S LOW STATIONARY FRONT REMAINS OVER THE REGION. IT WILL BE ANOTHER DIFFICULT DAY AS FAR AS WHERE AND WHEN THUNDERSTORMS WILL FORM. SOME GUIDANCE MEMBERS SUGGEST WE WILL HAVE LINGERING NOCTURNAL CONVECTION AGAIN WHICH WOULD SUPPRESS ADDITIONAL STORMS. OTHERS SUGGEST WE WILL HAVE THUNDERSTORMS ALL DAY ALONG THE BOUNDARY. AS SUCH HAVE CHANCE POPS. TEMPS WILL ONCE AGAIN BE A CONCERN ESPECIALLY IF CLOUD COVER LINGERS THROUGH THE DAY. BACKED OFF ON HIGH TEMPS A BIT DUE TO CLOUD COVER BUT STILL HAVE HIGHS IN THE UPPER 80S TO LOWER 90S AWAY FROM THE LAKE. FLOW WILL BE OFF OF THE LAKE SO TEMPS WILL BE LIMITED TO THE 70S. SHEAR AND CAPE ARE NOT AS PLENTIFUL TOMORROW SO THINKING WHILE WE MAY HAVE A FEW STRONG TO BORDER LINE SEVERE STORMS...WIDESPREAD SEVERE WEATHER IS NOT EXPECTED. GUIDANCE SUGGESTS STORMS WILL FIRE ALONG A VORTICITY STREAMER THURSDAY NIGHT AND PUSH INTO OUR REGION EARLY IN THE MORNING. THE RIDGE AXIS ALSO SHIFTS TO OUR EAST FRIDAY WITH NORTHWEST FLOW SETTING UP. THINKING FRIDAY WILL BE SIMILAR TO TODAY WHERE NOCTURNAL CONVECTION IS THE MAIN SHOW. AS SUCH BACKED OFF ON FRIDAY/S HIGH TEMPS TOO BUT KEPT THEM IN THE MID 80S AWAY FROM THE LAKE AS THE GROUND SHOULD WARM UP QUICKLY IN THE AFTERNOON. TEMPS ALONG THE LAKE WILL BE AROUND 80 DUE TO ONSHORE FLOW. FRIDAY LOOKS QUIET WITH CLEARING SKIES AND LOWS IN THE 60S. SATURDAY AND SUNDAY... MULTIPLE UPPER LEVEL SHORTWAVES WILL PASS OVER THE REGION THIS WEEKEND. HIGH PRESSURE WILL BE OVER THE EASTERN GREAT LAKES AND IF THE HIGH DRIFTS FARTHER WEST...IT COULD HELP LIMIT THUNDERSTORM DEVELOPMENT. HAVE LOW CONFIDENCE IN THUNDERSTORMS SATURDAY...AND HAVE POPS INCREASING THROUGH THE DAY TO CHANCE IN THE AFTERNOON AND OVERNIGHT AHEAD OF THE FIRST SHORTWAVE. SUNDAY LOOKS TO HAVE THE BETTER CHANCE OF THUNDER WITH THE SHORTWAVES AND GREATER INSTABILITY. SHEAR LOOKS LOW ON BOTH DAYS SO MAY SEE SOME STORMS PULSE UP ON SUNDAY BUT NOT EXPECTING WIDESPREAD SEVERE WEATHER. FOR TEMPS HAVE HIGHS IN MID TO UPPER 80S BOTH DAYS. SOUTHEAST FLOW ON SATURDAY COULD LEAD TO COOLING IN LAKE COUNTY IL...WHILE NO LAKE COOLING IS EXPECTED SUNDAY. MONDAY AND NEXT TUESDAY... THE PARADE OF SHORTWAVES CONTINUES INTO EARLY NEXT WEEK WITH A WEAK SURFACE LOW MOVING INTO THE MID MISSISSIPPI VALLEY TUESDAY OR WEDNESDAY. HAVE CONTINUED PERIODIC CHANCES OF STORMS BUT LOOKING AT COOLER TEMPS BEHIND THE RIDGE. HIGHS WILL STILL BE IN THE 80S BUT IN THE LOW TO MID 80S. ONSHORE FLOW IS ALSO EXPECTED WITH LAKE SIDE COOLING. JEE && .AVIATION... //ORD AND MDW CONCERNS...UPDATED 03Z... * TSRA LATE THIS EVENING. * SHRA/TSRA POSSIBLE OVERNIGHT AND THURSDAY. * POSSIBLE IFR/MVFR CIGS THRU THURSDAY MORNING. * EAST/NORTHEAST WINDS THURSDAY. CMS //DISCUSSION...UPDATED 03Z... TSRA CONTINUE TO DEVELOP ACROSS NORTHERN IL AND ARE LIKELY BEING FUELED BY WARM AIR ADVECTION ALOFT. MODELS SUGGEST THIS MAY CONTINUE THROUGH THE OVERNIGHT HOURS BUT CONFIDENCE REGARDING LOCATION/COVERAGE IS STILL LOW. HAVE INCLUDED VCTS AT RFD THRU THE NIGHT WHERE BETTER CHANCES APPEAR. ELSEWHERE CARRIED VCSH THRU THE NIGHT AFTER CONVECTIVE TRENDS FOR THE NEXT FEW HOURS. IFR CIGS HAVE REMAINED NORTH AND EAST OF THE TERMINALS. STILL LOWER CIGS NEAR AND OVER THE LAKE AND CONFIDENCE REGARDING IF AND WHEN THEY WILL PUSH FURTHER INLAND AND TO THE TERMINALS IS LOW AND ADDITIONAL CHANGES ARE LIKELY. CMS PREVIOUS 00Z DISCUSSION... LINE OF TSRA FROM MDW TO DKB WILL CONTINUE MOVING SOUTHEAST OVER THE NEXT FEW HOURS AND WHILE THERE MAY BE BRIEF BREAKS HAVE GONE PREVAILING TSRA DPA/MDW/GYY FOR THE NEXT FEW HOURS. ORD WILL BE ON THE NORTHERN EDGE OF THIS ACTIVITY. HAIL HAS BEEN REPORTED WITH THE STRONGEST STORMS BUT VERY HEAVY RAIN WILL ALSO BE POSSIBLE. WHILE CONFIDENCE IS NOT HIGH...EXPECT THIS ACTIVITY TO CONTINUE TO DRIFT SOUTH OF THE TERMINALS BY MID EVENING. ADDITIONAL SHRA AND TSRA WILL BE POSSIBLE OVERNIGHT INTO THURSDAY BUT CONFIDENCE REGARDING SPECIFIC TIMING IS LOW. THOUGH ELEVATED TSRA POSSIBLE PRIOR TO SUNRISE ACROSS NORTHERN IL AND SOUTHERN WI. OUTFLOW BOUNDARIES HAVE SHIFTED WINDS NORTHERLY AND THE MAIN COLD FRONT APPEARS TO BE NEAR A DPA/MDW LINE. GUSTY NORTHEAST WINDS WILL OCCUR WITH THE FRONT BUT DIMINISH SHORTLY AFTERWARD... LEAVING PREVAILING NORTHEAST WINDS 10-15KTS. WINDS WILL THEN REMAIN GENERALLY EASTERLY FOR THE REST OF THE PERIOD. COMBINATION OF SATURATED LOW LEVELS FROM THE STORMS AND COLDER AIR OFF LAKE MICHIGAN WILL LIKELY RESULT IN LOWER CIGS. HOW LOW AND HOW FAR INLAND IS UNCERTAIN BUT HAD INCLUDED IFR CIGS WITH AN EARLIER UPDATE AND MAINTAINED THEM WITH THIS FORECAST. LOWER CIGS MAY PERSIST INTO THURSDAY MORNING. CMS //ORD AND MDW CONFIDENCE...UPDATED 03Z... * HIGH FOR TSRA LATE THIS EVENING. * LOW FOR TSRA TRENDS OVERNIGHT/THURSDAY MORNING. * LOW FOR IFR/MVFR CIGS OVERNIGHT/THURSDAY MORNING. * MEDIUM FOR WINDS THROUGH THE PERIOD. CMS //OUTLOOK FOR ORD/MDW FOR 12Z FRIDAY-12Z WEDNESDAY...UPDATED 00Z... * FRIDAY THROUGH TUESDAY...CHANCE OF TSRA. && .MARINE... 146 PM CDT WIND DIRECTION WILL CONTINUE TO BE THE GREATEST CHALLENGE FOR THE NEXT 24 HOURS...IN ADDITION TO THE POTENTIAL FOR ANOTHER ROUND OF THUNDERSTORMS. A BROAD RIDGE OF HIGH PRESSURE CENTERED OVER HUDSON BAY WILL BEGIN TO STRETCH SOUTH OVER SOUTHERN LOWER MICHIGAN. TO THE WEST A NEARLY STATIONARY FRONTAL BOUNDARY THAT HAS BEEN THE FOCAL POINT FOR THUNDERSTORMS WILL BECOME ORIENTED FROM THE SOUTHERN TIP OF THE LAKE STRETCHING NORTHWEST THROUGH SOUTHWEST MINNESOTA THIS EVENING. IN GENERAL...SOUTH WINDS ARE EXPECTED SOUTH OF THE BOUNDARY WITH NORTHEAST WINDS NORTH OF THE BOUNDARY. AN AREA OF LOW PRESSURE OVER THE PLAINS WILL EVENTUALLY LIFT NORTH AND ALLOW THE FRONTAL BOUNDARY TO LIFT BACK NORTH OVER THE LAKE THURSDAY NIGHT INTO FRIDAY. HIGH PRESSURE WILL BUILD JUST EAST OF LAKE MICHIGAN LATE IN THE WEEK INTO THE WEEKEND AND SHOULD RESULT IN RELATIVELY MODEST WINDS ACROSS THE LAKE THIS WEEKEND INTO EARLY NEXT WEEK.
