DISCUSSION...

Water vapor imagery highlights an upper-level shortwave over central
Lake Huron which will pivot south into Lake Erie and the Ohio Valley
through the night. Negligible impacts for Southeast Michigan under
anemic moisture with PW values of .25 inches and building surface
pressure. Gradual increase with upper-level confluent flow will
reinforce surface high pressure as it expands across the Great Lakes
through tomorrow afternoon, bringing another day of dry weather under
mostly sunny skies. Airmass modification under mid-april solar
insolation will boost afternoon highs into the mid-50s.

Pacific northwest wave will arrive onshore tonight and will ride
through the northern Plains and southern Provinces through the
weekend which will result in modest a boost of an upper-level ridge
over the Great Lakes leading into early next week. Downstream warm
front amplification will commence over the Great Lakes which will
result in modest thermal advection Sunday before the warmest push
enters Monday afternoon. Temperatures continue to climb through
Monday, peaking in the 60s by Monday afternoon. Prior, there will be
a brief window for light rain showers Sunday morning and afternoon
along an elevated warm front. Lack of instability will preclude the
mention of any thunderstorm chances.

Lower-end PoP chances (20-30%) will carry into Monday accounting for
the lower end chance for a glancing shortwave to develop elevated
precipitation, but otherwise the rush of warmer temperatures will
likely develop some degree of capping. Warmer temperatures will be
short-lived once a pre-frontal trough and cold front then move
through Tuesday, returning temperatures back into the 40s to low 50s
for a daytime high. Boosted mixing depths in the wake of the front
and possibly some more synoptic-based subsidence behind the trough
will likely bring breezy conditions through the day, with early
ensemble diagnosis showing the potential for gusts to reach around or
above 40 mph.

MARINE...

Quiet marine conditions heading into the weekend as high pressure is
building across the region. Light northerly winds will persist into
Saturday before the ridge axis traverses the region which will flip
winds around to the south later on Saturday. Winds remain out of the
south on Sunday while increasing slightly with gusts to around 20
knots. An elevated warm front will also pass over the region on
Sunday bringing a chance of rain showers at times. Increased chances
of rain across the northern Great Lakes Sunday night as a low
pressure system starts tracking across Lake Superior.
