THIS HAZARDOUS WEATHER OUTLOOK IS FOR PORTIONS OF SOUTHWEST
IOWA...WEST CENTRAL IOWA...EAST CENTRAL NEBRASKA...NORTHEAST
NEBRASKA AND SOUTHEAST NEBRASKA.
.DAY ONE...TODAY AND TONIGHT
SCATTERED MORNING THUNDERSTORMS WILL NOT BE SEVERE AND WILL MOVE
OUT OF THE AREA BY NOON. THERE IS A CHANCE FOR MORE STORMS
DEVELOPING BY LATE AFTERNOON ACROSS ALL OF THE OUTLOOK AREA...BUT
BETTER CHANCES WILL AGAIN COME OVERNIGHT AS STORMS MOVE OUT OF THE
HIGH PLAINS INTO EASTERN NEBRASKA AND WESTERN IOWA. SEVERE STORMS
ARE NOT EXPECTED...BUT SOME STORMS COULD PRODUCE SMALL HAIL AND
GUSTY WINDS.
A WARM FRONT LIFTING NORTH INTO EASTERN NEBRASKA AND SOUTHWEST
IOWA COULD TRIGGER ISOLATED TO SCATTERED STORMS LATE IN THE
AFTERNOON. BUT RELATIVELY STABLE AIR LEFT BEHIND AFTER MORNING
SHOWERS AND STORMS SUGGEST ADDITIONAL THUNDERSTORM DEVELOPMENT
WILL HOLD OFF UNTIL THE OVERNIGHT HOURS AS A STRONGER LOW LEVEL
JET KICKS IN. BY THIS TIME...THE WARM FRONT WILL HAVE LIFTED INTO
NORTHEAST NEBRASKA AND WEST CENTRAL IOWA...SO THE BEST CHANCE FOR
STORMS WILL LIE THERE.
.DAYS TWO THROUGH SEVEN...SUNDAY THROUGH FRIDAY
INTERMITTENT PERIODS OF THUNDERSTORMS ARE POSSIBLE SUNDAY AND
MONDAY...BUT AGAIN THE RISK FOR SEVERE STORMS IS LOW. AND THESE
STORMS WILL ALSO FAVOR THE EVENING AND OVERNIGHT HOURS. THERE IS
POTENTIAL FOR HEAVY RAIN WITH ANY OF THE STORMS THROUGH MONDAY.
BETTER CHANCES FOR SEVERE THUNDERSTORMS WILL COME TUESDAY THROUGH
THURSDAY AS STRONGER WINDS AND COOLER TEMPERATURES AT MID LEVELS
OVERSPREAD THE REGION. EXACT TIMING OF THE GREATEST POTENTIAL FOR
SEVERE WEATHER WILL BE OUTLINED WITH LATER OUTLOOKS.
.SPOTTER INFORMATION STATEMENT...
STORM SPOTTER ACTIVATION SHOULD NOT BE NEEDED TODAY OR TONIGHT.
