.SHORT TERM /THROUGH TONIGHT/...
Issued at 251 AM EDT Fri Jun 14 2024

Pattern Synopsis:

Longwave troughing stretching from Hudson Bay down over the Great
Lakes will continue to progress eastward today as the associated
surface cyclone treks northeast across Quebec. Increasingly
amplified ridging will fold over the region tonight, providing
subsidence aloft that will build surface high pressure from the
northern Great Plains overhead by Saturday morning.

Forecast Details:

Sunny skies, mild temperatures today -- Quiet weather is in store
for northern Michigan today and tonight as aforementioned high
pressure builds into the region. North winds will advect cooler,
drier air into the region today with sunny skies in place underneath
subsidence aloft. Winds aren`t expected to gust as high as they did
Thursday, but gusts to around 20 mph will be possible at times
through the afternoon. Highs look to warm into the mid to upper 70s
for most areas today with slightly cooler temperatures anticipated
across the eastern U.P. and along the immediate lakeshores. Calm
winds and clear skies will lead to efficient radiational cooling
tonight, allowing for overnight temperatures to drop well into the
40s across interior northern lower.

.LONG TERM /SATURDAY THROUGH THURSDAY/...
Issued at 251 AM EDT Fri Jun 14 2024

Weak midlevel long wave troughing over the northern half of North
America continues the pattern of mostly quiet weather with chances
of showers at times. Upstream midlevel shortwave riding over the
Pacific northwest will begin to build and progress across the
country, eventually causing surface high pressure to deliver
clear/sunny skies and pleasant weather for the weekend.

Aformentioned riding will continue to occupy the eastern half of
North America and allow for temperatures to surge well above
normal across the Great Lakes region for mid June. Embedded
height disturbances and the advection of a (somewhat) humid air
mass to the region will continue chances of showers at times
next week, but impacts regarding precipitation remain low.

Primary Forecast Concerns/Key Messages:

-Temperatures begin to build this weekend through the entirety
 of the long term. Watching for potential record breaking highs
 by midweek next week: Aformentioned midlevel ridging with an
 embedded jet maxima will begin to advect northward and reach
 the southern shore of Hudson Bay by the Wednesday timeframe.
 Biggest story of the long term is the well advertised incoming
 heat as surface temperatures slowly climb throughout the
 entirety of the forecast period. Warmest days for the CWA
 remain Monday through Thursday as daytime highs are expected to
 surge into the upper 80s to low 90s for most locations. One
 issue that could tamper temperatures next week is the potential
 of convective storms at times, mixing warm surface
 temperatures with cooler low level temps. Guidance continues to
 keep H8 temperatures around 20 degrees Celsius, so proper
 mixing with a potential MCS or even strong enough winds could
 greatly reduce forecasted high temperatures. As for
 precipitation impacts, no heavy rainfall or severe weather is
 expected at this time.

.AVIATION /12Z TAFS THROUGH 12Z SATURDAY/...
Issued at 600 AM EDT Fri Jun 14 2024

VFR conditions are expected across northern Michigan for the vast
majority of the issuance period. Lingering BR/FG at MBL and CIU is
expected to burn off within the next hour or two as diurnal mixing
ensues. Otherwise, sunny/clear skies are anticipated today and
tonight as high pressure builds into the Great Lakes. FG/BR may
develop across parts of northern Michigan again tonight, but
relatively low confidence due to dry low-level air being advected
into the region precludes explicit mention in the TAFs at this
time.
