.SHORT TERM...(Today and tonight)
Issued at 345 AM EDT SAT JUL 30 2016

Today and Tonight: High pressure will remain in control of the
pattern through this time period, bringing quiet weather, other than
some afternoon CU along any lake breeze boundaries that form. Highs
today will top out in the upper 70s to around 80 away from the Great
Lakes, which is near to slightly above normal for this time of year.
Along the Great Lakes, highs will be in the low to mid 70s.
Overnight lows will be cool once again, but perhaps a little warmer
as PWAT values climb higher with the low center sliding slowly
eastward. Lows will likely be in the upper 40s to around 50 inland.
Elsewhere, expect lows to be mainly in the 50s to around 60 with the
warmest temperatures along the Great Lakes shorelines. For
reference, average lows this time of year are right around the mid

.LONG TERM...(Saturday night through Friday)
Issued at 303 PM EDT FRI JUL 29 2016

Surface ridging over the Great Lakes will continue to influence the
weather across Upper Michigan into early next week.  As upper
ridging begins to build back into the Great Lakes early next week we
will see a steady warming trend.  85H temps will climb from around
12C on Sunday into the lower 20s C by the middle of the week. As
southerly low level flow increases...there will be a noticeable
increase in humidity.

Some diurnal shower and thunderstorms activity will begin to become
a possibility again by next Tuesday into Wednesday but limited
forcing will keep chances in the slight to low chance range through
mid week.

A cold front will move into the area by later next week.  Extended
models still differ some on the overall timing with the GFS quickest
with a Thursday frontal passage and the ECMWF a little slower.  Will
continue with a consensus approach with an increase in pops for
later next week with details being fine tuned with time.

.AVIATION...(For the 06Z TAFS through 06Z Saturday night)
Issued at 118 AM EDT SAT JUL 30 2016

Expect VFR conditions and light winds to prevail this fcst period
with hi pres dominating. There may be some shallow ground fog at the
more sheltered IWD location early this mrng as the temp there has
already fallen to the crossover dewpt. A limiting factor may be some
mid clds drifting ovhd.

.MARINE...(For the 4 AM Lake Superior forecast issuance)
Issued at 345 AM EDT SAT JUL 30 2016

High pressure will linger across Lake Superior into early next week.
This will keep winds around or less than 15 kts.
