CANADIAN HIGH PRESSURE WILL EXIT THE AREA TODAY PROVIDING ONE LAST
DAY OF PLEASANT WEATHER. TONIGHT...A THUNDERSTORM COMPLEX IS
FORECAST TO DEVELOP IN THE PLAINS AND MOVE ACROSS IOWA. THIS

AN ACTIVE WEEK OF WEATHER IS EXPECTED WITH DANGEROUS HEAT AND

DISSIPATE. BOUNDARIES LAID OUT BY THIS COMPLEX WILL BECOME THE
FOCUS FOR THUNDERSTORM DEVELOPMENT MONDAY AFTERNOON. SEVERE WEATHER
IS LIKELY LATE MONDAY AFTERNOON AND NIGHT DUE TO SUFFICIENT SHEAR.
STORMS THAT DEVELOP WILL QUICKLY EVOLVE IN TO A SEVERE SQUALL LINE...
WITH HIGH WINDS BEING THE PRIMARY THREAT. HOWEVER ISOLATED TORNADOES
CANNOT BE RULED OUT. ADDITIONALLY...HEAVY RAIN IS ALSO POSSIBLE DUE
TO VERY WARM AND MOIST AIR FEEDING INTO THE STORM SYSTEM.

APPROACH 105 DEGREES DURING THE AFTERNOON.

TUESDAY NIGHT THROUGH FRIDAY MORNING...ADDITIONAL ROUNDS OF
THUNDERSTORMS CAN BE EXPECTED. HEAVY RAIN IS A THREAT FROM EACH
