302 pm cdt wed jul 1 2026

is the average of the highest 1/3 of the wave, along with the
average height of the highest 10% of the waves which will

.synopsis...

high pressure around 30.1 inches will remain parked over the

pressure system around 29.5 inches in west central manitoba slowly 
moves east toward james bay by friday. breezy south to southwest 
winds will persist through thursday. southwest winds will weaken

region for the weekend. 

chances for thunderstorms (50-60%) remain across the northern half 
of the lake through tonight. tonight into thursday morning there is 
a small chance (~20%) for rain and storms across the southern half. 
the chances for storms will persist through thursday afternoon

additional chances for rain/storms remains across the entire lake 
saturday and sunday.strong to severe storms may occur at times,
