Area Forecast Discussion
National Weather Service Marquette MI
709 AM EDT WED AUG 10 2016

.SHORT TERM...(Today and tonight)
Issued at 327 AM EDT WED AUG 10 2016

Weak cold front continues to make slow but steady progress southward
across the forecast area tonight. A few showers and thunderstorms
did develop along the boundary earlier across the Keweenaw and
Ontonagon county, but they have since dissipated. The boundary will
stall out across the southern sections of the area today.

Surface ridging over Ontario should be enough to push some drier air
into northern portions of the area today with north to northeast
winds allowing for a cooler day along Lake Superior.

As upper low moves out of the Pacific Northwest along the
U.S./Canadian border increasing warm advection ahead of it should
allow widespread shower and thunderstorms activity to break out
across the northern plains into northern MN during the day today. A
few showers and thunderstorms could make it into western Lake
Superior and the western part of the U.P. by late this afternoon,
but most areas will remain dry through the daytime today.

As surface low moves eastward out of the plains tonight along
stalled frontal boundary extending into the Upper Great Lakes,
increasing low level jet focused into MN will allow for a
widespread area of shower and thunderstorm activity to develop
upstream of the U.P. The leading edge of this precipitation will
push across Western Lake Superior during the overnight and extend
from the Keweenaw to the western U.P. by daybreak Thursday.

.LONG TERM...(Thursday through Tuesday)
Issued at 320 AM EDT WED AUG 10 2016

Main fcst concerns in the medium/extended range wl focus on pops/
potential for some heavy rain on Thu/Thu ngt in the moist SW flow
ahead of shrtwv moving thru the nrn Rockies. As this shrtwv sags
into the Upper Lks over the weekend, some showers could linger as
cooler air slowly arrives. Dry and pleasant wx wl return early next
week as trailing hi pres builds over the area.

Thu/Thu ngt...Shrtwv now over the nrn Rockies is fcst to move E
thru the plains along the Cndn border, reaching near Lk Winnipeg by
12Z Fri. Although the sharper deep lyr qvector cnvgc associated with
this shrtwv wl remain to the NW of Upr MI, moist SW flow ahead of
this disturbance over stnry fnt thru the Ncentral Great Lks and under
upr dvgc in RRQ of 100kt h3 jet max across SE Canada suggest a good
bet for some badly needed rain arriving W to E on Thu. Drying aloft
on the srn flank of the shrtwv near Lk Winnipeg wl tend to diminish
pops over at least the W later on Thu night. Overall, the models
have been inconsistent on their handling of the fcst details during
this time. Recent runs of the Cndn model have been most consistent
showing triple pt sfc lo pres moving the fnt across the U.P. on Thu
night. Given the other model variability, tended toward the Cndn
fcst scenario. Slow moving nature of the sfc lo pres along stnry fnt
parallel to the WSW flow aloft in the presence of pwat near 2 inches
/aoa 200 pct of normal/ continues to point toward the potential for
some at least locally heavy rain. But uncertainty on the location of
stnry fnt/track of sfc lo pres/deeper forcing and potential for
convection dvlpg to the S that could disrupt mstr inflow still offers
much uncertainty on the qpf and other fcst details. Although incrsg
clds/shower chcs on Thu wl limit the diurnal temp increase over the
W half, min temps on Thu ngt should wl be well above normal under the
moist airmass.

Fri thru Sun...Shrtwv near Lk Winnipeg at 12Z Fri is fcst to drift
slowly to the ESE and to near the Upper Lks over the weekend.
Although mid lvl drying on the srn flank of this shrtwv wl tend to
diminish the more widespread rain on Fri, the general model trend
has been to have this disturbance slide farther to the SE into the
Great Lks, with weakening occluded fnt/lo pres trof lingering
nearby. While the drier air in the mid lvls that overspreads the
area on Fri wl reduce pcpn chcs, presence of weak lo pres trof
under axis of lower h5 hgts wl offer at least the potential for some
sct showers, especially during the aftn/evng hrs. As h85 temps slowly
fall toward 10C over the weekend, expect a cooling trend.

Mon thru Wed...As hgts begin to rise following the exit of the
troffing in the Great Lks, sfc hi pres is fcst to build into the
area early next week. Expect dry wx and pleasant temps on Mon/Tue
under this hi pres. Some pcpn may return Tue ngt/Wed as another
weak shrtwv aprchs and interacts with a warmer/moister SW flow in the
wake of the slowly departing sfc hi pres.
&&

.AVIATION...(For the 12Z TAFS through 12Z Thursday morning)
Issued at 709 AM EDT WED AUG 10 2016

IFR cigs at SAW will improve this morning. Otherwise...expect mainly
VFR conditions into Thursday morning. Upslope flow into SAW will
likely produce VFR cigs again by late tonight.
&&

.MARINE...(For the 4 AM Lake Superior forecast issuance)
Issued at 327 AM EDT WED AUG 10 2016

High pressure will build southward out of Ontario across most of
Lake Superior today. North to northeast winds will be in the 10-20
knot range over the eastern lake today. Funneling and coastal
convergence in the favorable northeasterly winds over the western
lake will result in higher winds in the 20-25 knot range there.  As
low pres approaches from the W on Thu, plan on easterly winds up to
20kt across the entire lake. The low will pass across the Upper
Great Lakes on Fri, followed by a wind shift to the n. Ne winds on
Sat will tend to slowly diminish with the approach of trailing high
pres. The high pres will settle into the Upper Great Lakes on Sun
and persist into early next week.
