Scattered light rain, mixed at times with light snow or flurries
persisted across the state during the morning hours. Amounts were
generally one quarter of an inch or less. The precipitation was 
mainly over the southern half of the state. Otherwise, skies were 
mostly clear across the east and parts of west central into northwest 
Iowa and cloudy across the remainder. Early morning low temperatures 
were in the upper teens northeast to the lower and middle 30s central
and south. Southeast winds were 10 to 15 mph.

A warm front, stretched over Nebraska will push east across Iowa 
today with the light rain and snow mixture ending later this afternoon.
Warmer afternoon temperatures are expected with highs ranging from 
the mid 40s over the northeast to the lower 60s in the far west today.
Mostly cloudy conditions will remain over the region tonight as 
milder air heads into the region. Friday will see big changes. A 
large storm system will bring abundant moisture into the Central 
Plains. Widespread rainfall is expected along with moderate to heavy 
wet snowfall over portions of northern, eastern and northeast Iowa, 
southern Minnesota, southwest Wisconsin and northwest Illinois. 
Snowfall totals may exceed 6 or more inches with the heavier snow and 
winter storm watches have been posted for portions of northern Iowa 
and surrounding states. Over the remainder of Iowa, much of the 
precipitation will fall as rain. Over an inch of rainfall is possible.

Highs Friday will be cooler over most of the area with high in the 
lower 40s north to the lower to mid 50s south. The storm will
continue into Saturday. After the storm pulls east on Saturday highs 
will warm from Saturday into Sunday back into the 30s northeast to the

Hazardous Weather Outlook For CLINTON County,IA

402 PM CDT Thu Mar 22 2018


No hazardous weather is expected at this time.


A Winter Storm Watch remains in effect for parts of the outlook 
area from Friday night through early Saturday afternoon. Total 
snowfall accumulations of 5 to 8 inches are possible with 
localized amounts near 10 inches. In addition to the heavy wet 
snow, winds could gust between 30-35 mph. Another concern is the 
possibility for sporadic power outages if the combination of the 
heavy snow and strong winds were to bring down tree branches.

South of Interstate 80 where rain will be more prevalent, there
will be the chance for some embedded thunderstorms later Friday
night into early Saturday morning. Some of these storms may
produce small hail and cloud to ground lightning.


Spotter activation will not be needed today or tonight.
