.SHORT TERM...(Today and tonight)
Issued at 412 AM EDT FRI JUL 29 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 lake breeze boundaries, and near to slightly
below normal temperatures. Highs today will top out in the mid to
upper 70s away from the Great Lakes, which is very near normal for
this time of year. Overnight lows will drop down into the 40s once
again for inland locations, especially over inland-central locations
of the U.P. as the high pressure center and drier air aloft slides
over the area. Elsewhere, expect lows to be mainly in the 50s with
the warmest temperatures along the Great Lakes. For reference,
average lows this time of year are right around the mid 50s. There
may also be some patchy fog that develops late tonight as the winds
become light and radiational cooling is maximized. The area that
would have the greatest potential for patchy fog would be inland
central and inland west, especially close to the WI border where the
better soil moisture is located due to the recent rainfall in those

.LONG TERM...(Friday night through Thursday)
Issued at 220 PM EDT THU JUL 28 2016

over the central U.S. The broad 500 mb trough remains over the upper
Great Lakes through Sun night. Will continue with a dry forecast for
this period and will not make any changes to the going forecast.
Looks quiet and warm for this forecast.

In the extended, GFS and ECMWF show a 500 mb ridge across the
southern Rockies and southern plains 12z Mon with a trough across
the Ern U.S. with the pattern changing little into Wed. A surge of
warmer air tries to come in for Wed. Upper level troughing moves in
for Thu into the upper Great Lakes with a cold front moving through
the area. Temperatures look to stay above normal for this forecast
period. Will have some low chance pops starting on Mon night in the
west and then cwa wide for Tue onward as a warm front approaches the
area with the best chance for rain on Thu.

.AVIATION...(For the 06Z TAFS through 06Z Friday night)
Issued at 129 AM EDT FRI JUL 29 2016

Expect VFR conditions and relatively light winds to prevail at all 3
TAF sites this fcst period as dry hi pres builds across the Upper
Great Lakes region. The only concern is the potential for some
shallow ground fog to impact the IWD site early this mrng with
favorable radiational cooling conditions/lighter winds.

Issued at 412 AM EDT FRI JUL 29 2016

High pressure will linger across Lake Superior into the upcoming
weekend. This will keep winds around or less than 15 kts into the

early next week as a cold front approaches the Upper Great Lakes
