Area Forecast Discussion
National Weather Service Marquette MI
220 PM EDT THU JUL 28 2016

.SHORT TERM...(This evening through Friday)
Issued at 220 PM EDT THU JUL 28 2016

Tonight: A quiet cool night is expected across the CWA. The drier
air will become more firmly in place across the Upper Peninsula
tonight as the high pressure center slides toward the western end of
Lake Superior. This will allow NE winds to become light and variable
late causing temperatures to drop well below normal for much of the
U.P. and especially the interior west in closer proximity to center
of high. PWATs of .4 inch or lower combined with the clear
skies/light winds should ensure ideal radiational cooling allowing
interior west mins to drop into the lower to mid 40s. Mins over the
interior central and over the Keweenaw Peninsula will generally  be
in the lower 50s with mid to upper 50s near the Great Lakes shores.

Fri, expect a nice day for late July with max temps close to normal
(generally mid to upper 70s) and comfortable dewpoint readings
mainly in the low/mid 50s as sfc high pres continues to dominate.
Dewpoints will be highest near the Great Lakes as the warming water
is resulting in the Lakes becoming a source of increased boundary
layer moisture. Fcst soundings suggest sct to perhaps locally bkn cu
forming over the interior ahead of developing lake breeze

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

Nam shows a 500 mb ridge on the desert sw 00 Sat with a broad trough
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 18Z TAFS through 18Z Friday afternoon)
Issued at 1247 PM EDT THU JUL 28 2016

Expect VFR conditions to prevail at all 3 TAF sites this fcst as
high pressure dominates the Upper Great Lakes region. Winds will be
fairly light out of the north to northeast, except light and variable

.MARINE...(For the 4 PM Lake Superior forecast issuance)
Issued at 220 PM EDT THU JUL 28 2016

High pressure, building into the Upper Great Lakes Region today,
will linger across Lake Superior into the upcoming weekend. This
will keep winds around or less than 15 kts into the weekend. The
next chance of winds approaching 20 knots would be early next week
as a cold front approaches the Upper Great Lakes region.
