348 PM EDT Mon Jun 13 2022

This hazardous weather outlook is for portions of southwest Lower
Michigan.

.DAY ONE...Late This Afternoon and Tonight

The potential remains for significant severe thunderstorms and
localized flooding this evening into tonight. The primary severe
threat is damaging winds, it is possible significant winds to over
75 mph are possible from the stronger storms. Large hail also
remains a threat as does isolated tornadoes. Since these storms
will be associated with a warm front pushing northward into this
area, training thunderstorms are expect too, locations that get
several storms tonight could see enough rainfall to result in
localized flooding. The storms are expected to move to the east
southeast around 40 to 50 mph.

.DAYS TWO THROUGH SEVEN...Tuesday through Sunday

Heat indices will be up around 100 degrees on Tuesday and
Wednesday afternoon and evening. Tuesday night and Wednesday night
will see temperatures stay quite warm, and will limit recovery
from the heat for people that do not have air conditioning. This
could be a bigger problem due to any widespread power outages
that may occur from the storms tonight.

Additional storms are possible Wednesday night into Thursday with
the passage of the cold front.

.SPOTTER INFORMATION STATEMENT...

Spotter activation is likely tonight for areas south of I-96.

This hazardous weather outlook is for portions of southwest Lower
Michigan.

.DAY ONE...This Afternoon and Tonight

There is a potential of some significant severe weather late this
afternoon into the mid evening across Southwest Lower Michigan.
The main time of concern is from now until about 2 am Tuesday
morning. Damaging winds of 60 mph will be the main threat, with
some significant winds of over 75 mph possible. There are lower
chances of hail and a waterspout. The highest chance of severe
weather will be south of Whitehall.

In addition, a meteotsunami event could occur for the southern
shoreline if the storms were to move fast enough across the area.
This would create possible coastal flooding and would cause very
dangerous conditions for anyone near the water or on piers.

.DAYS TWO THROUGH SEVEN...Tuesday through Sunday

There is the potential for winds and waves that could be
hazardous to smaller craft from Tuesday and especially Wednesday
into Thursday. Thunderstorms are also possible later Wednesday
into early Thursday.

.SPOTTER INFORMATION STATEMENT...

Spotter activation is likely tonight for areas south of Little
Sable Point
