AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ST LOUIS MO
1136 PM CDT THU JUN 21 2007

.DISCUSSION...
A BROAD UPPER RIDGE WILL REMAIN MORE OR LESS STATIONARY THROUGH
THE WEEKEND. HOWEVER A DECENT DISTURBANCE NESTLES INTO THE FRONT
SIDE OF THE RIDGE AND TAKES UP RESIDENCE OVER MISSOURI THROUGH THE
WEEKEND. FOR TONIGHT...AN MCS IS ALREADY TRAVELING THROUGH WEST
CENTRAL IOWA AND HEADED SOUTHEAST. IT SHOULD SCRAPE THROUGH OUR
NORTHERN COUNTIES THIS EVENING AN SO WE HAVE INCREASED OUR POPS TO
LIKELY CATEGORIES FOR THIS EVENT. MOST OF THE HEAVY ACTIVITY WILL
BE JUST NORTH OF OUR CWA FROM IOWA INTO CENTRAL ILLINOIS TONIGHT.
HOWEVER THE OUTFLOW FROM THIS ACTIVITY SHOULD SET OFF ACTIVITY
AGAIN TOMORROW AND WILL PROBABLY BE A LITTLE FURTEHR SOUTH.
THEREFORE WE HAVE KEPT LIKELY CHANCES IN FOR TOMORROW NIGHT
CENTERED ON OUR NORTHERN COUNTIES AND DECENT CHANCE POPS FOR
SATURDAY.

I ALSO THREW IN CHANCE POPS FOR SUNDAY AS THIS UPPER AIR WEAKNESS
REMAINS TRAPPED OVER OUR AREA. THE AXIS OF HIGHEST INSTABILITY
REMAINS OVER MISSOURI AND ILLINOIS THROUGH THE WEEKEND AND I
THINK THIS SHOULD LEAD TO AT LEAST SCATTERED ACTIVITY FOR SUNDAY
AFTERNOON AND EVENING.

I MENTIONED LOCALLY HEAVY RAINS NORTH TOMORROW NIGHT AS WE COULD
VERY WELL GET REPEAT CONVECTION AND WITH ANTECENDENT RAINS TONIGHT
IT SHOULD GRADUALLY LOWER FLASH FLOOD VALUES. SOMEONE WILL GET A
LOT...COULD BE NORTHEAST MISSOURI...COULD BE A LITTLE FURTHER
NORTH IN IOWA INTO CENTRAL ILLINOIS AGAIN. COULD USE THE RAIN.

PEDIGO

&&

.AVIATION...
FOR THE 06Z TAFS...VFR CONDITIONS EXPECTED TO CONTINUE
OVERNIGHT WITH WINDS REMAINING LIGHT. TOMORROW MORE CONVECTION IS
LIKELY TO OCCUR NEAR THE FRONT AND ANY LEFTOVER BOUNDARIES AS CWA
REMAINS IN WARM SECTOR.
