.DISCUSSION...
/402 AM CDT FRI OCT 23 2009/

THE UPPER LOW WAS ON THE MOVE THIS MORNING AND WAS LOCATED NEAR
OMAHA AT 08Z...WITH THE ATTENDANT COLD FRONT AND A SERIES OF SFC
LOWS INVOF OF THE MS RIVER. THE MAIN SHIELD OF RAIN HAS PUSHED OUT
OF THE CWA AS THE DRY SLOT HAS PROGRESSED ACROSS THE AREA...
LEAVING JUST SOME PATCHY LIGHT RAIN AND DRIZZLE IN ITS WAKE. THE
SFC LOWS WILL CONSOLIDATE AND DEEPEN THIS MORNING...LIFTING NEWD
TO THE LAKE MICHIGAN VCNTY BY EARLY EVENING IN ASSOCIATION WITH
THE LIFTING UPPER LOW. WITH CAA...GUSTY NW WINDS AND SOLID LOW
CLOUDS...EXPECT NEARLY STEADY OR A SLIGHT FALL IN TEMPERATURES
TODAY. PATCHY LIGHT RAIN AND DRIZZLE SHOULD BE IT AS FAR AS PCPN
GOES. A SECOND SHORTWAVE IS FCST TO DIG ACROSS THE AREA TONIGHT
BRINGING A NEW SLUG OF MID LEVEL MOISTURE AND SOME WEAK LRG SCALE
ASCENT. THIS WILL AT LEAST MAINTAIN THE THREAT OF DRIZZLE TONIGHT
ALONG WITH SEEDING THE LOW LEVELS TO BRING A CHANCE OF SOME
MEASURABLE LIGHT RAIN TO AREAS ALONG AND NORTH OF I-70. EXPECTING
CLOUDS TO CLEAR BY MIDDAY ON SATURDAY WITH WAA COMMENCING BY
AFTERNOON AND SOME DECENT TEMP RECOVERY...BUT HIGHS REMAINING
BELOW AVERAGE.

A NEW TROF WILL DIG INTO THE CENTRAL U.S LATE SAT NIGHT THROUGH
MONDAY WITH AN ATTENDANT COLD FRONT PROGRESSING THRU THE CWA SUN
NGT INTO EARLY MON. A PRONOUNCED WAA REGIME IN ADVANCE OF THE COLD
FRONT COMBINED WITH DECENT MOISTURE AND LARGE SCALE LIFT WILL
SUPPORT A GOOD CHANCE OF RAIN SUN INTO SUNDAY NIGHT. THE LATEST
GFS...ECMWF...AND CMC GEM ALL SUPPORT THIS SCENARIO I HAVE BUMPED
UP POPS. IF THE 12Z RUNS CONTINUE THIS TREND...THEN AT LEAST
LIKELY POPS WILL BE IN ORDER.

WITH A GUSTY WLY SFC WND BUT THE STRATUS CLOUDS CURRENTLY BLW
1000 FT AT THE TAF SITES SHOULD ONLY SLOWLY RISE IN HGT LTR THIS
MRNG AND AFTN. CEILINGS HGTS WILL LIKELY NOT RISE TO MORE THAN
1500 TO 2000 FT BY LT AFTN. THIS GRADUAL RISE IN CIG HGTS SHOULD
CONT TGT WITH CLRG LT TGT AND EARLY SAT MRNG AS THE MID-UPR LVL
TROF MOVES E OF THE CWA WHILE A SFC RDG DROPS SEWD THRU THE
