Severe Weather OutlookHazard Risk

National Weather ServiceLa Crosse, WI Situation ReportFriday, June 26, 2020 12:58 PM

50 to 60 mph wind gusts

Isolated hail up to quarters (1” diameter)

Isolated, brief tornadoes

Maybe isolated flooding in flood-prone urban areas.

Discussion: The severe weather threat this afternoon is a highly conditional based on how fast the storms are able to develop into a line this afternoon.

• Faster development of a line would increase the threat for damaging winds and isolated tornadoes especially in northeast Iowa and southwest Wisconsin.

• Slower development of a line would result in the severe weather threat being more in south-central & southeast Wisconsin and northern Illinois.

Severe Thunderstorm Preparedness

A Severe Thunderstorm Watch is issued when conditions are favorable for severe

thunderstorms to develop. When a watch is issued, it is time to prepare and stay weather aware.

A Severe Thunderstorm Warning is issued when a thunderstorm poses a threat to life or

property. Now is the time to act!

Have a NOAA weather radio handy and make sure it is tuned to the right transmitter:

How do I stay safe? Go indoors and stay away from windows. If you are caught outside, do not

seek shelter underneath a tree – they are prone to lightning strikes. A hard-topped vehicle may

offer some protection as a last resort. Do not touch the sides of the vehicle.

All thunderstorms can be deadly: When Thunder Roars, Go indoors!
