HIGH PRESSURE CONTINUES TO DOMINATE THE PATTERN THROUGH THE
BEGINNING OF NEXT WEEK. EXPECT A BEAUTIFUL WEEKEND WITH ABOVE
AVERAGE TEMPERATURES AND BLUE SKIES. A LOW PRESSURE SYSTEM OVER
NORTH DAKOTA CONTINUES TO MOVE NORTHEAST TOWARD THE HUDSON
BAY...WHILE A CLOSED LOW WILL FORM TONIGHT OVER THE FOUR CORNERS
OUT WEST. THE CLOSED LOW WILL OPEN UP ON SUNDAY...BUT THE LARGE
RIDGE OVER THE EASTERN HALF OF THE US WILL KEEP THE LOW TO OUR
WEST AND PUSH IT INTO MANITOBA.
THE PATTERN SHIFTS WITH A BROAD TROUGH STRETCHED ACROSS CONUS BY
WEDNESDAY LEADING TO MORE UNSETTLED WEATHER FOR OUR NECK OF THE
WOODS. A COLD FRONT WILL APPROACH FROM THE WEST ON WEDNESDAY.
SHOWERS AND A THUNDERSTORM OR TWO WILL FORM ALONG THE COLD FRONT
BRINGING MUCH NEEDED RAIN TO THE AREA. ALTHOUGH ATTM...IT APPEARS
THAT RAINFALL TOTALS WILL NOT BE SUBSTANTIAL.
FOR THE NEXT FEW DAYS...UNSEASONABLE WARM WEATHER WILL CONTINUE.
SOUTHERLY FLOW WILL BE WEAKER TOMORROW AS THE PRESSURE GRADIENT
RELAXES...BUT STILL EXPECTING TEMPERATURES TO REACH INTO THE LOW
80S FOR MUCH OF THE CWA TOMORROW AND SUNDAY. A COOLING TREND
BEGINS ON MONDAY...WITH MORE SEASONABLE TEMPS ARRIVING ON
THURSDAY.

HIGH PRESSURE AND DRY WEATHER WILL REMAIN WITH US THROUGH THE
EARLY PART OF NEXT WEEK. A LOW PRESSURE SYSTEM PASSING TO OUR WEST
IS CAUSING THE PRESSURE GRADIENT IN OUR NECK OF THE WOODS TO
TIGHTEN...RESULTING IN GUSTY SOUTHERLY FLOW THIS AFTERNOON. WIND
GUSTS THIS AFTERNOON WILL BE UP TO 25 KT...WITH HIGHER GUSTS WEST
OF I-39. RH VALUES THIS AFTERNOON WILL BE IN THE LOWER 30S...WITH
DEWPOINTS IN THE LOW TO MID 50S. MOISTURE WILL SLOWLY INCREASE
OVERNIGHT AND SATURDAY...WITH RH VALUES TOMORROW BOTTOMING OUT IN
THE LOW 30S IN CENTRAL IL. WINDS WILL BE NOT AS GUSTY TOMORROW AS
THE PRESSURE GRADIENT RELAXES...BUT UNSEASONABLY WARM WEATHER WILL
CONTINUE THROUGH MONDAY.

* GUSTY SOUTHERLY WINDS THROUGH SUNSET AND AGAIN SATURDAY. CMS
//DISCUSSION...UPDATED 18Z...
A STRENGTHEN PRESSURE GRADIENT BETWEEN A TROUGH OF LOW PRESSURE TO
THE WEST AND HIGH PRESSURE TO THE EAST...COMBINED WITH AMPLE
SUNSHINE WILL ALLOW FOR SOUTHERLY WINDS TO GUST TO 20-25KT DURG
THE AFTERNOON HOURS. GUSTS HAVE BEEN A LITTLE SLOW TO DEVELOP OVER
NRN IL/NWRN IN...SO HAVE PUSHED BACK ONSET OF GUSTS TO 19Z.
GUSTINESS SHOULD SUBSIDE AT SUNSET...BUT PREVAILING SOUTHERLY
WINDS NEAR 10KT SHOULD PERSIST THROUGH THE NIGHT TONIGHT. A
SIMILAR SETUP IS LIKELY FOR TOMORROW WITH SOUTHERLY GUSTY WINDS
EXPECTED AGAIN.
OTHERWISE...WITH A STRONG RIDGE ALOFT OVER THE REGION...WEATHER
WILL BE DRY...WITH ONLY SOME CI FOR CLOUD COVER. NO PCPN IS EXPECTED
THROUGH THE PERIOD AND CIGS/VIS WILL BE UNOBSTRUCTED.

324 PM CDT
AS A LARGE RIDGE OF HIGH PRESSURE CONTINUES TO REMAIN SITUATED
ACROSS THE ATLANTIC COAST TODAY...FLOW WAS INITIALLY ON THE
LIGHTER SIDE BUT HAS SINCE INCREASED ALL ACROSS THE REGION AND THE
LAKE TODAY AS AN AREA OF LOW PRESSURE CONTINUED TO INCREASE AS IT
MOVED THROUGH THE NORTHERN PLAINS. WITH THIS LOW SLOWLY GETTING
CLOSER TODAY...THE PRESSURE GRADIENT AND FLOW ALOFT HAS BEEN
INCREASING WITH SOUTHERLY FLOW AT THE SURFACE OUT AHEAD OF THIS
SYSTEM ALSO INCREASING. WITH THE SURFACE FEATURES REMAINING
SIMILAR INTO SATURDAY...CONDITIONS OVER THE LAKE WILL ALSO REMAIN
SIMILAR. ALTHOUGH WITH THIS SOUTHERLY FLOW IN PLACE...WARMER AIR
HAS BEEN MOVING ACROSS THE COOLER LAKE HELPING TO CREATE MORE
STABLE CONDITIONS. WITH THESE STABLE CONDITIONS IN PLACE...WINDS
WONT BE AS STRONG TONIGHT INTO SATURDAY. ALTHOUGH FLOW ALOFT IS
PRETTY STRONG NOT TOO FAR OFF OF THE LAKE...SO FEEL THAT THESE
STRONGER GUSTS TO 30 KT MAY BE PERIODICALLY REALIZED TONIGHT INTO
EARLY SATURDAY MORNING...AND HAVE SINCE CONVEYED THIS IN THE
FORECAST. THEN FLOW TO SLOWLY DIMINISH INTO THE REMAINDER OF THE
WEEKEND WITH PRESSURE FIELD TO BECOME MORE RELAXED.
