AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SPRINGFIELD MO
138 AM CDT TUE JUN 29 2010

DISCUSSION...
HIGHLIGHTS: QUIET AND DRY WEATHER IS EXPECTED THROUGH THE WORK
WEEK WITH GRADUALLY INCREASING CHANCES FOR RAIN/TSTMS IN THE
EXTENDED PORTION OF THE FCST AS SOME SUBTROPICAL BEGINS TO RETURN TO
THE REGION.

A RIDGE OF HIGH PRESSURE NOSING SOUTH INTO THE MIDDLE AND LOWER
MO RIVER VLY BROUGHT LOWER DEW POINTS AND COOLER TEMPERATURES TO
THE REGION. HIGH CLOUDS CONTINUE TO STREAM NORTH ATTM BUT WILL
HAVE LITTLE INFLUENCE ON DAYTIME TEMPERATURES FOR THE MOST PART.
THE DRY AIR MASS COUPLED WITH SOMEWHAT DRYER THAN NORMAL GROUND
AND PLANT MOISTURE OVER SOUTH CENTRAL MISSOURI MAY ALLOW A LARGER
SWING IN DIURNAL TEMPERATURE THAN DEPICTED BY MOS GUIDANCE OVER
THE NEXT FEW DAYS AND HAVE BUMPED UP AFTERNOON HIGHS JUST A BIT
THERE.

THE UPPER RIDGE AND ASSOCIATED SFC HIGH WILL GRADUALLY SHIFT EAST
WITH TIME...BUT A GENERAL NORTHEAST THEN EAST SFC FETCH WILL KEEP
A DRY AIR MASS IN PLACE THROUGH FRI/EARLY SAT. AS THE UPPER
HIGH/RIDGE AXIS SHIFTS EAST OF THE REGION...WE SHOULD SEE A
GRADUAL RETURN OF MOISTURE. RETAINED SOME SMALL/SLIGHT POPS FOR
SAT...BUT BETTER CHANCES WILL LIKELY HOLD OFF UNTIL SUNDAY AND/OR
MON AS WE SEE THE POTENTIAL FOR SOME MID LATITUDE DIPS IN THE MID
LEVEL FLOW...OR AT THE VERY LEAST LOW AMPLITUDE SHORTWAVES
INTERACTING WITH THE INCREASING MOISTURE. DSA
