Hazardous Weather Outlook For LOUISA 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.
