Area forecast discussion, Jun 21, 6:45 PM CDT, 27 minutes before
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHICAGO/ROMEOVILLE IL
645 PM CDT SAT JUN 21 2014

.DISCUSSION...
200 PM CDT

MAIN CONCERNS FOR TONIGHT WILL CONTINUE BE ON THE POTENTIAL FOR
ISOLATED THUNDERSTORMS ALONG WITH REDEVELOPING FOG.

NORTHERN IL/NORTHWEST IN HAVE BECOME UNSTABLE WITH GENERALLY MU-CAPE
VALUES BETWEEN 2000-3000J/KG...WITH A WEAK MID-LVL VORT SLIDING
EAST/SOUTHEAST ACROSS THE FORECAST AREA. THIS WILL SERVE AS THE
FOCAL POINT FOR SEEING ISOLATED STORMS...POSSIBLY SEVERE STORMS
BETWEEN 20-23Z THEN EXPECTED TO STEADILY DECREASE IN COVERAGE AND
INTENSITY BY 2Z. TEMPS WILL REMAIN MILD OVERNIGHT WITH LOWS
GENERALLY IN MID/UPR 60S AND A FEW LOCATIONS ONLY DIPPING TO ARND
70. THERE WILL REMAIN AN ISOLATED POTENTIAL FOR SHRA/TSRA
OVERNIGHT...HOWEVER THE FOCUS OVERNIGHT WILL BE ON FOG DEVELOPMENT.
WITH A VERY MOIST ENVIRONMENT LINGERING OVER THE REGION
TONIGHT...FOG DEVELOPMENT IS VERY FAVORABLE. HOWEVER THE CHALLENGE
WILL BE ON THE INTENSITY. AT THIS TIME WILL LEAN TOWARDS VSBY ONLY
DIPPING TO ARND 1-3SM...HOWEVER A FEW POCKETS OF PATCHY DENSE FOG
MAY OCCUR.

SUNDAY...
VERY WARM/MOIST ATMOSPHERE WILL LINGER THRU SUN AS WELL. NOT
PLANNING TO MAKE MANY CHANGES TO THE GOING FORECAST FOR SUN. STILL
LOOKS TO BE A GOOD CHC FOR SEEING SCATTERED STORMS REDEVELOP IN
THE MIDDAY THRU AFTN TIMEFRAME. GUIDANCE HAS BEEN INDICATING SOME
MID-LVL DIFFLUENCE RIDING ALONG A WEAK RIDGE FOR THE MIDDAY/AFTN
SUN TIMEFRAME. THIS COULD ACT AS AN INHIBITOR FOR CONVECTIVE
DEVELOPMENT. ALTHOUGH CONFIDENCE IN THE STRENGTH OF THIS IS
MINIMAL...SO HAVE OPTED TO KEEP THINGS AS IS FOR SUN AND MENTION
THE TSRA POTENTIAL.

WITH AN EXPECTED TURNING IN THE WINDS...IT IS POSSIBLE THAT A
LAKE BREEZE COULD PUSH INLAND AND KEEP TEMPS COOLER FOR FAR
NORTHEAST IL. AT THIS TIME THE THINKING IS THAT WINDS WILL REMAIN
SOUTHERLY FOR THE MOST PART. PWAT VALUES WILL LINGER ARND
1.5-2"...WITH CONTINUED MOISTURE CONVERGENCE IN THE LOW/MID
LEVELS. SO WHATEVER STORMS ARE ABLE TO DEVELOP...THEY WILL LIKELY
BE ABLE TO EFFICIENTLY PRODUCE VERY HEAVY RAINFALL.

BEACHLER

LONG TERM... SUNDAY NIGHT THROUGH SATURDAY...
412 PM CDT

SCATTERED SHOWERS AND THUNDERSTORMS EXPECTED TO CONTINUE INTO
SUNDAY NIGHT AS WARM FRONT ASSOCIATED WITH PLAINS LOW PRESSURE
EDGES NORTH AND EAST ACROSS THE AREA. WITH SFC DEW POINTS
REMAINING IN THE MID-UPPER 60S COMBINED WITH STRENGTHENING LOW
LEVEL JET TO OUR WEST... FEED OF WARM MOIST AIR TO REMAIN VERY
AVAILABLE TO FUEL STORMS.

COVERAGE OF STORMS THEN EXPECTED TO INCREASE MONDAY INTO MONDAY
NIGHT AS LOW PRESSURE TRACKS FROM IOWA ACROSS WISCONSIN TO THE
EASTERN U.P. OF MICHIGAN. GIVEN SHORTWAVE TROUGH ALOFT... INCREASING
LOW LEVEL CONVERGENCE ALONG A COLD FRONT EXPECTED TO SWEEP ACROSS
THE FORECAST AREA MONDAY NIGHT... COMBINED WITH AFOREMENTIONED
ENVIRONMENT OF ABUNDANT MOISTURE... LIKELY POPS WARRANTED WITH
POTENTIAL FOR A ROUND OF HEAVY RAIN POSSIBLE GIVEN VERTICAL
MOISTURE PROFILES.

FLOW ALOFT TURNS NORTHWEST ON TUESDAY ALBEIT WITH EMBEDDED
SHORTWAVES AND RESIDUAL MOISTURE LINGERING BEHIND THE COLD FRONT.
WILL MAINTAIN LOW CHANCE POPS FOR INSTABILITY SHOWERS/
THUNDERSTORMS MAINLY DIURNALLY ENHANCED. SURFACE HIGH PRESSURE
RIDGES ACROSS THE AREA WEDNESDAY AND THURSDAY BUT NOT WITHOUT
MODELS CONTINUING TO INDICATE WEAK SHORTWAVES RIDING THROUGH THE
FLOW ALOFT BECOMING MORE ZONAL. THE COLD FRONT THAT MOVES THROUGH
THE AREA MONDAY NIGHT/EARLY TUESDAY STALLS OUT OVER SOUTHERN
ILLINOIS THEN BEGINS TO LIFT BACK NORTH AS A WARM FRONT THURSDAY
NIGHT AND FRIDAY. AS INSETROPIC ASCENT INCREASES AHEAD OF THE
BOUNDARY WILL CARRY CONTINUED LOW POPS FRIDAY... AND INTO SATURDAY
AS THE WARM FRONT LIFTS NORTH ACROSS THE AREA.

.AVIATION...

//ORD AND MDW CONCERNS...UPDATED 00Z...

* TSRA EARLY THIS EVENING.
* WIND DIRECTIONS THIS EVENING.
* IFR/LIFR CIGS OVERNIGHT/SUNDAY MORNING.
* POSSIBLE FOG OVERNIGHT/SUNDAY MORNING.
* EAST WINDS SUNDAY. CMS

//DISCUSSION...UPDATED 00Z...

TSRA WILL CONTINUE TO MOVE SOUTHEAST AND AWAY FROM THE TERMINALS
OVER THE NEXT 1-2 HOURS WITH LINGERING SHRA. MAIN CONCERN WILL BE
WIND DIRECTIONS THIS EVENING AFTER CONVECTIVE WINDS DIMINISH.
UPSTREAM OBS SHOW LIGHT NORTH/NORTHEAST WINDS BECOMING LIGHT AND
VRB IN SOME LOCATIONS. WITH A POSSIBLE MARINE/LAKE INFLUENCE HAVE
GONE WITH PREVAILING NORTHEAST WINDS THIS EVENING BUT SPEEDS
SHOULD REMAIN UNDER 10KTS. WIND WILL EVENTUALLY BECOME LIGHT AND
VRB OVERNIGHT.

WITH THE CONTINUED MOIST LOW LEVELS AND THE MARINE/LAKE INFLUENCE
NOTED ABOVE...EXPECT IFR/LIFR CIGS TO RETURN/DEVELOP OVERNIGHT AND
THEN LIFT SUNDAY MORNING BUT CONFIDENCE REGARDING SPECIFICS/TIMING
AND DURATION IS LOW. FOG POTENTIAL MAY BE A BIT MORE OF A
CONCERN...ESPECIALLY AWAY FROM THE LAKE AND WHERE ANY LOW CLOUDS
FORM AND VIS 1SM OR LOWER WILL BE POSSIBLE.

WINDS REMAIN EASTERLY SUNDAY AND CURRENTLY NO STRONG SIGNALS FOR
TSRA BEFORE SUNDAY EVENING AND HAVE REMAINED DRY WITH THIS
FORECAST. CMS

//ORD AND MDW CONFIDENCE...UPDATED 00Z...

* HIGH FOR PRECIP TRENDS THIS EVENING.
* MEDIUM FOR WINDS THROUGH THE PERIOD.
* LOW FOR IFR/LIFR CIGS TONIGHT/SUNDAY MORNING.
* MEDIUM FOR FOG TONIGHT/SUNDAY MORNING. CMS

.MARINE...
234 PM CDT

GENERALLY LIGHT WIND REGIME OUTSIDE OF THUNDERSTORM INDUCED WINDS TO
CONTINUE THOUGH MONDAY NIGHT WHEN A COLD FRONT WILL SWEEP ACROSS THE
LAKE BRINGING DRYER CONDITIONS AND NORTHERLY FLOW BY TUESDAY.  UNTIL
THEN... EXPECT AREAS OF DENSE FOG TO PERSIST OVER THE LAKE WITH
WINDS GENERALLY REMAINING AT OR BELOW 20 KTS AND WAVES AT OR BELOW 3
FEET. WINDS AND WAVES WILL BE HIGHER NEAR THUNDERSTORMS.

A RIDGE OF HIGH PRESSURE FROM JAMES BAY TO THE CENTRAL GREAT LAKES
WILL REMAIN NEARLY STATIONARY TONIGHT AND THEN GRADUALLY DRIFT EAST
SUNDAY.  MEANWHILE WEAK LOW PRESSURE OVER WISCONSIN WILL SLIDE
SOUTHEAST ALONG A NEARLY STATIONARY FRONTAL BOUNDARY ACROSS NORTH
CENTRAL ILLINOIS TO SOUTHEAST ILLINOIS OVERNIGHT AND DISSIPATE.  WEAK
LOW PRESSURE OVER THE CENTRAL PLAINS WILL BECOME BETTER ORGANIZED AS
IT DOES AND MOVE EAST.  THIS LOW WILL REACH CENTRAL IOWA BY DAYBREAK
MONDAY AND MOVE TO THE EASTERN UPPER PENINSULA OF MICHIGAN BY
OVERNIGHT MONDAY INTO TUESDAY.

A WEAK COLD FRONT ASSOCIATED WITH THIS LOW WILL THEN SWEEP ACROSS THE
LAKE LATE MONDAY NIGHT INTO TUESDAY...TURNING WINDS FROM SOUTHERLY
TO NORTHERLY. BROAD HIGH PRESSURE WILL THEN BUILD INTO THE UPPER
GREAT LAKES WEDNESDAY LASTING INTO THURSDAY.
