.DISCUSSION...
KEY MESSAGES:

1) Breezy west to northwest winds are expected on Friday behind
the cold front, with Lake Wind conditions. Gusts to around 40 mph
are expected.

2) Cooler temperatures are also expected Friday and Saturday with
showers and isolated thunderstorms Friday.

3) Another round of thunderstorms can be expected late Sunday.
Severe thunderstorms are possible.

WEATHER PATTERN OVERVIEW:

Vertically stacked low pressure over the Prairie Provinces will
drop into Montana Friday, bringing showers, isolated mainly
afternoon thunderstorms and plenty of wind. It`ll probably feel
more like early May rather than late June as temperatures are
only expected to top out in the 60s most places.

Upper ridging will guide warm and dry weather on Saturday before
more ensembles hint at more active weather early next week. This
next system looks to move in late Sunday. This system could also
bring severe thunderstorms to the area but specifics are still
fuzzy this far out.

FORECAST CONFIDENCE & DEVIATIONS:

Will turn our attention to the system that moves in Sunday. Severe
thunderstorm chances are there but initially don`t look as strong
as with this system.

Wind gusts Friday will probably be accelerated by showers. Gusts
to 50 mph cannot be ruled out in their vicinity. TFJ
