.DISCUSSION...
/ISSUED 304 PM CDT FRI JUL 31 2015/
WITH DEW POINTS IN THE LOWER TO MIDDLE 50S...A MUCH MORE PLEASANT
DAY WAS REALIZED AND THE GOOD NEWS IS....THAT SHOULD CONTINUE FOR
THE NEXT FEW DAYS. THE SYNOPTIC PATTERN WILL REMAIN FAIRLY
CONSISTENT WITH RIDGING TO THE WEST AND AN UPPER TROUGH TO THE NORTH
LEAVING THE LOCAL AREA WITH WEAK HIGH PRESSURE AT THE SURFACE AND A
DRY NORTHERLY FLOW THROUGH THE COLUMN. THIS WILL SET THE STAGE FOR
SUNNY/CLEAR SKIES WITH HIGHS IN THE LOWER 90S AND LOWS IN THE 60S
THROUGH THE WEEKEND.

HEIGHTS RISE SLIGHTLY MON/TUE AS THE RIDGE TO THE WEST NOSES INTO
THE AREA. NO PRECIP CONTINUES BUT HIGHS WILL WARM A FEW DEG INTO THE
MIDDLE 90S. A RETURN FLOW STARTS TO DEVELOP BY MONDAY EVENING WHICH
WILL BRING THE HUMIDITY BACK UP WITH DEW POINTS INTO THE MIDDLE TO
UPPER 60S BY MID WEEK.

THE UPPER TROUGH STARTS TO DIG FARTHER SOUTH TUESDAY NIGHT INTO
WEDNESDAY AND DIFFERENCES IN THE GUIDANCE START TO BECOME MORE
APPARENT. A COLD FRONT WILL START TO DRAG INTO THE MIDWEST TOWARDS
THE AREA BY WEDNESDAY SO THE NEXT CHANCE OF SHOWERS/THUNDERSTORMS
WILL BE WEDNESDAY AHEAD OF THIS SYSTEM. WHAT HAPPENS NEXT IS A BIT
OF A TOSS UP WITH THE ECMWF BRINGING A LOW QUICKLY ALONG THE FRONT
AND OUT BY THURSDAY WITH VERY LITTLE PRECIP. THE GFS HOWEVER DEEPENS
THE LOW AND CREATES A DISTINCT SURFACE LOW OVER THE MIDWEST. THIS
WILL BRING A MORE EXTENDED PERIOD OF SHOWERS/THUNDERSTORMS TO THE
AREA FOR THE END OF THE WEEK. IT IS TOO FAR OUT AT THIS POINT TO
WARRANT MORE THAN CHANCE POPS. TEMPS WILL REMAIN NEAR NORMAL VALUES
FOR THE MID TO END WEEK PERIOD.
