334 PM CDT
NO REAL FORECAST CONCERNS IN THE NEAR TERM...ONLY ISSUES ARE WITH
WARMING TEMPERATURES THROUGH THE REMAINDER OF THE WEEK...WHICH I
DONT THINK ANYONE WILL HAVE ISSUES WITH AT THIS TIME.
UPPER LEVEL RIDGE REMAINS SITUATED ACROSS THE REGION WITH THE
RIDGE AXIS OVERHEAD TODAY...WITH LARGE SURFACE RIDGE OF HIGH
PRESSURE MAINTAINING ITS DOMINANCE ACROSS THE REGION. WITH THIS
RIDGE IN PLACE...QUIET WEATHER PERSISTS ACROSS NORTHEAST ILLINOIS
AND NORTHWEST INDIANA. THE ONLY REAL FEATURES IN AND AROUND THE
REGION ARE WITH SOME WEAK IMPULSES ROUNDING THIS UPPER LEVEL
RIDGE...HELPING WITH SOME MID AND HIGH LEVEL CLOUD COVER ACROSS
THE UPPER MIDWEST AND CENTRAL GREAT LAKES REGION. MODELS IN FAIR
AGREEMENT WITH THIS UPPER LEVEL RIDGE TO SLIDE SLIGHTLY TO THE
EAST INTO FRIDAY...BUT WITH RISING HEIGHTS FORECAST TO OCCUR. AS
THIS OCCURS...THE CWA WILL GET INTO A BETTER WAA REGIME WITH
PLEASANT WEATHER TO PERSIST WITH WARMING TEMPERATURES INTO THE
WEEKEND. AN ABUNDANCE OF SUNSHINE TODAY HAS HELPED WITH
TEMPERATURES QUICKLY WARMING TODAY...WITH TEMPERATURES MAKING IT
TO AROUND 80 AND EVEN SOME LOWER 80S ACROSS THE SOUTHERN PORTIONS
OF THE CWA.
ALL GUIDANCE CONTINUES TO UNDER FORECAST TEMPERATURES...WITH THIS
BEING THE ONLY REAL FORECAST ISSUE GOING INTO THE WEEKEND. WITH
PERSISTENT WAA AND MAIN THERMAL AXIS SHIFTING OVERHEAD...FEEL
TEMPERATURES WILL ONLY CONTINUE TO WARM INTO THE WEEKEND. SO HAVE
BUMPED UP MAX/MIN TEMPERATURES OVER GUIDANCE INTO THE WEEKEND.
EXPECT TEMPERATURES TO MAKE IT INTO THE 80S ONCE AGAIN ON
THURSDAY...WITH EVEN AREAS ALONG THE LAKE ALSO OBSERVING THESE
HIGHER TEMPS. DESPITE WEAK FLOW AND THE DEVELOPMENT OF A LAKE
BREEZE...TEMPS ALONG THE LAKE WERE ABLE TO RISE RATHER CLOSE TO 80
TODAY. WITH SOUTHERLY FLOW CONTINUING TO INCREASE INTO THE WEEKEND
THIS WILL ONLY CONTINUE TO HELP THESE AREAS ALSO OBSERVE THESE
TEMPS WITH SATURDAY ESPECIALLY THE CASE AS ALL AREAS WITHIN THE
CWA FORECAST TO MAKE IT INTO THE 80S...WHICH WILL CONTINUE TO BE
WELL OVER CLIMO.

DRY WEATHER WILL CONTINUE WITH DEW POINTS EXPECTED TO REMAIN IN
THE 40S...POSSIBLY REACHING 50 DEGREES FOR FAR NORTHERN SECTIONS
OF ILLINOIS. WINDS WILL CONTINUE TO REMAIN LIGHT FROM THE
SOUTH...OR AROUND 5 TO 10 MPH FOR MOST LOCATIONS. THIS COUPLED
WITH AFTERNOON TEMPERATURES WARMING WELL INTO THE 70S...AND ARND
80 DEGREES WILL RESULT IN RELATIVE HUMIDITY VALUES IN THE LOW/MID
30 PERCENT RANGE. THE AREA OF GREATEST CONCERN WILL BE ALONG AND
SOUTH OF A DIXON TO KANKAKEE LINE.

142 PM CDT
GENERALLY BENIGN WEATHER ON THE LAKE THE NEXT SEVERAL DAYS.
FAIRLY STRONG EAST WINDS OVER FAR NORTHERN PORTIONS OF THE LAKE
NEAR THE MACKINAW STRAIGHTS WILL SUBSIDE THIS EVENING.
OTHERWISE...MAINLY SOUTH TO SOUTHEAST FLOW WILL GRADUALLY
STRENGTHEN THE NEXT FEW DAYS...PARTICULARLY OVER NORTHERN PORTIONS
OF THE LAKE. DESPITE THE INCREASING GRADIENT...NOT LOOKING FOR
WINDS TO GET TO EXCESSIVELY STRONG AS AIR MASS WILL BE
UNSEASONABLY WARM OVER THE COLD LAKE RESULTING IN VERY STABLE
CONDITIONS.
