AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE QUAD CITIES IA IL
255 AM CDT THU JUL 8 2010

.SYNOPSIS...
SURFACE ANALYSIS AT 2 AM SHOWS COOL FRONT JUST WEST OF MISSISSIPPI RIVER
MOVING EAST AT 15 MPH.  THIS PUTS FRONT EAST OF FORECAST AREA BY 8 AM.
SLIGHTLY DRIER AIR AND LIMITED FORCING SUPPORTED BY RADAR TRENDS AS
SHRA/TSRA TO BE EAST OF AREA BY SUNRISE. UPPER AIR ANALYSIS SHOWS
SEASONAL MID JULY NORTHERN PLAINS HIGH PRESSURE AND SUBSIDENCE TO MOVE
INTO AREA NEXT COUPLE OF DAYS WITH SLIGHTLY BELOW NORMAL TEMPS AND
MODEST DEWPOINTS.  ..NICHOLS..

&&

.SHORT TERM...TODAY AND TONIGHT...
TODAY...HAVE REDUCED POPS AND CANCELLED FLASH FLOOD WATCH AS FORCING
TO BE EAST OF AREA AS COOL FRONT MOVES WELL EAST OF AREA. INSPECTION
OF LOW LEVELS SUGGEST ENOUGH LOW LEVEL MOISTURE TO ALLOW SOME WEAK
POPCORN -SHRA...MAINLY IN THE AFTERNOON OVER SE PORTIONS.  AN
ISOLATED...BRIEF TSRA POSSIBLE...BUT LIMITED LOW LEVEL CONVERGENCE
WIND FIELDS SUGGESTS THIS UNLIKELY. NW WINDS OF 10 TO 15 MPH COMBINED
WITH HIGHS IN THE LOWER 80S TO RESULT IN A MORE COMFORTABLE DAY.
SKIES MAY CLEAR FASTER THAN SUGGESTED WITH SUBSIDENCE FOR DAY SHIFT
TO CONSIDER.

TONIGHT...CLEARING SKIES AND LOWER DEWPOINTS SUGGEST LOWS NEAR 60
DEGREES NORTH TO NEAR 65 ALONG IOWA AND MISSOURI BORDER. KEPT LOW
POPS FAR SE BUT LARGER SCALE FORCING SUPPORTS DAY SHIFT MAY BE ABLE
TO REMOVE POPS ENTIRELY.    ..NICHOLS..

.LONG TERM...FRIDAY THROUGH NEXT WEDNESDAY...
FRIDAY THROUGH SATURDAY NIGHT...LOOKS DRY WITH WARM SUNNY DAYS AND
CLEAR COMFORTABLE NIGHTS. THIS WILL BE DUE TO A NORTHWEST FLOW ALOFT
AND SURFACE HIGH PRESSURE OVER THE REGION. THE COOLEST NIGHT STILL
PROGRAMMED TO BE EARLY SATURDAY WITH MIN TEMPS DIPPING INTO THE MID
TO UPPER 50S IN SOME OF MY NORTHERN LOCATIONS. MAX TEMPS BOTH FRIDAY
AND SATURDAY IN THE 80S BUT AT LEAST THE HUMIDITY LEVELS WILL BE
MORE TOLERABLE COMPARED TO THE PAST SEVERAL DAYS.

IF THE ECM/GFS/NAM IS TO BE BELIEVED THEN WE WILL BE ABLE TO SQUEEZE
OUT ONE MORE DRY DAY ON SUNDAY TO COMPLETE THE WEEKEND. HOWEVER THE
GEM RAMS AN MCS ACROSS THE CWA. IN ANY CASE THE DEWPOINTS SHOULD BE
PUSHING BACK INTO THE 60S ON THE RETURN FLOW AROUND THE DEPARTING
HIGH. FOR NOW HAVE KEPT THE MENTION OF SMALL POPS WEST OF THE MS RVR
ON SUNDAY LETTING LATER SHIFTS EVALUATE IF WE NEED POPS OR NOT.

WITH A DECENT WARM ADVECTION PATTERN SUNDAY NIGHT INTO MONDAY AND
DYNAMICS FROM A RATHER POTENT TROUGH SWINGING THROUGH...WILL
CONTINUE IDEA OF A POSSIBLE MCS IMPACTING MY CWA. WITH SHEAR AND
INCREASING CAPE THERE IS THE POTENTIAL FOR BOTH SEVERE WEATHER AND
HEAVY RAINS. FOR NOW HAVE INCREASED POPS A BIT FOR SUNDAY NIGHT AND
WILL PROBABLY NEED TO BE RAISED FURTHER. WILL CONTINUE TO MONITOR
MODEL TRENDS. NO CHANGES WERE MADE BEYOND MONDAY.  ..HAASE..
