IT APPEARS WE ARE IN STORE FOR ONE MORE SOMEWHAT PROLONGED EPISODE OF THUNDERSTORMS FROM TONIGHT THROUGH WEDNESDAY. LITTLE HAS CHANGED IN THE OVERALL PATTERN WITH ONE OR MORE STALLED BOUNDARIES NEARBY.
THE NEXT REAL WEATHER MAKER IS CURRENTLY LOCATED OVER THE PACIFIC NORTHWEST AND WILL MOVE ACROSS IOWA LATE TONIGHT AND WEDNESDAY. THIS WILL RESULT IN RAPID DEVELOPMENT OF STORMS OVERNIGHT ACROSS EASTERN NEBRASKA AND MOVE ACROSS IOWA LATE TONITE AND EARLY MORNING WEDNESDAY...STORMS WILL REDEVELOP AND PERSIST DURING THE DAY WEDNESDAY UNTIL A COOL FRONT CLEARS OUR AREA EARLY WEDNESDAY NIGHT. THE SEVERE WEATHER THREAT APPEARS MINIMAL (RIGHT NOW) AND MOSTLY CONFINED TO SOUTHERN IOWA NEAR THE SURFACE FRONT.....HOWEVER, EXPECT HEAVY RAIN ALONG THE I-80 CORRIDOR OVERNITE AND EARLY MORNING WED.
BY WEDNESDAY EVENING THE FRONT WILL BE MOVING OFF TO THE EAST AND WE WILL BE PLACED BENEATH NORTHWESTERLY FLOW ALOFT (HIGH PRESSURE) WITH A LARGE SURFACE HIGH BUILDING INTO THE UPPER MIDWEST AND PUSH THE FRONTAL
BOUNDARY OFF TO OUR SOUTH. THIS WILL RESULT IN A COUPLE OF DAYS OF DRY AND RELATIVELY COOLER WEATHER FOR THE REMAINDER OF THE WEEK.
BY SATURDAY: THE HIGH WILL MOVE OFF TO THE EAST AND WE WILL SEE A RETURN OF SOUTHERLY FLOW - INCREASING OUR TEMPS AND MOISTURE SPARKING SHOWERS AND STORMS ONCE AGAIN...
