EVENT...PRELIM TO TONIGHT'S CONVECTIVE COMPLEX ALREADY HAS BEGUN IN
WESTERN IA...
.
SATELLITE ANALYSIS AND TRENDS...TWO SHORT WAVE TRIGGERS SEEN IN GOES
IR/WV LOOPS THAT ARE HELPING FIRE PRELIM CONVECTION TO TONIGHT'S LARGER
CONVECTIVE COMPLEX LATER ON.  ONE SHORT WAVE MOVING THRU SW MN/NW IA
WAS ALLOWING CONVECTION FROM S MN TO INCREASE/DEVELOP SOUTHWARD INTO IA
(IE...FROM FREEBORN COUNTY MN TO POCOHONTAS/HUMBOLDT COUNTY IA).   WHILE
FIRST SPOKE OF SHORT WAVE ENERGY COMING OUT ACROSS CENTRAL NEBRASKA WAS
HELPING TO DESTABILZE W IA ENOUGH FOR ADDITIONAL CONVECTION TO DEVELOP.
AT THE SAME TIME PW MOISTURE WAS POOLING ACROSS W IA AND SE NEBRASKA
MAXING OUT AT 1.25 INCHES TO 1.4 INCHES.  THIS SHOULD GET A LITTLE
HIGHER THIS EVENING...BUT MORE IMPORTANTLY THE MOISTURE GRADIENT
(DRYING VS MOISTENING) WILL SHARPEN AND ADD MORE INSTABILITY TO THE
AREA AS ADDITIONAL SHORT WAVES COME OUT INTO THE PLAINS THIS LATER
THIS EVENING/TONIGHT.  AREA OF W IA ALSO IN A WEAK 300MB DIVERGENCE AND
WEAK DIFFLUENT REGION WITH 70KT UPPER LEVEL JET FROM N AZ/N NM NOSING
INTO KS AND MO.  FRONTAL BOUNDARY WILL BE FOCUS OF CONTINUED CONVECTIVE
DEVELOPMENT FROM SE NEBRASKA INTO
W CENTRAL IA AND WOULD EXPECT CURRENT CONVECTION TO BE A PRELIM TO THE
CONVECTIVE COMPLEX THAT MAY START BACK IN SE/E NEBRASKA OVERNIGHT/LATER
THIS EVENING/TONIGHT AND MOVE ACROSS AREAS NOW GETTING THE PRELIM
CONVECTION...IE HARRISON...SHELBY...CRAWFORD COUNTY.    WILL CONTINUE
TO MONITOR...SEE GRAPHICAL ANALYSIS ON HOME PAGE AT ADDRESS BELOW...
