Area Forecast Discussion
National Weather Service Marquette MI
859 AM EDT Fri Jun 18 2021

.UPDATE...
Issued at 856 AM EDT FRI JUN 18 2021

...CRITICAL FIRE WEATHER CONDITIONS FOR ALL OF UPPER MICHIGAN
TODAY...

The combination of persistent dry conditions, expected low
relative humidities today and west winds gusting to 30 to 40 mph
will lead to critical fire weather conditions for all of Upper
Michigan today. Avoid outdoor burning and any activities which
will lead to open flames or sparks today. See the latest red flag
warning for further details.

&&

.SHORT TERM...(Today and tonight)
Issued at 503 AM EDT FRI JUN 18 2021

WV imagery and RAP analysis indicated a mid/upper level trough
through northwest Ontario with nearly zonal flow through the
northern CONUS. A shortwave and associated MCS was sliding to the
east from southern Wisconsin. An upstream shrtwv diving southeast
from far northwest Ontario was dragging a cold front toward Lake
Superior. Otherwise, a trough extended through central Upper
Michigan into central WI with drier air filtering into western upper
Michigan.

Today, with plenty of sunshine and deep mixing to around 8k feet,
temps will climb into the low to mid 80s with dewpoints falling to
around 40. This will drop RH values into the 20-25 percent range
over the west and in the 25-30 pct range east. The very dry air
combined with wnw winds gusting to around 30 mph will result in
critical or near critical fire weather condiions to most of Upper
Michigan. Some higher gusts may be possible given the 30-40 knot
winds toward the top of the mixed layer.

Tonight, Models suggest that rain associeated with another shrtwv
moving from southern Saskatchewan through northern MN to WI is
likely to remain to the west and south of Upper Michigan but may
clip the far west or south. As winds diminish, temps will drop into
the upper 40s inland and the lower 50s near the Great Lakes.

.LONG TERM...(Saturday through Thursday)
Issued at 520 AM EDT FRI JUN 18 2021

Longwave troughing develops over our CWA this weekend into early
next week with generally below normal temperatures and near to below
normal precipitation. The primary feature of interest in the
extended period is an area of low pressure tracking northeast
through or just south of our CWA Sunday night into Monday.
Widespread precipitation is expected with this system, but precip
amounts seem insufficient to provide lasting drought relief. A much
cooler air mass moves in on Monday with much below normal
temperatures expected to last through Wednesday morning. Return flow
on Wednesday signals a return to near or above normal temperatures
ahead of the next trough that approaches late next week.

Northerly winds off Lake Superior on Saturday should result in a
cool day along the northern shorelines. Winds veer southerly on
Sunday ahead of a deepening low pressure system tracking near or
just to the south of our CWA. This southern storm track implies most
of the precipitation will miss to our south where substantial warm
sector convection is expected. Thus, precipitation amounts across
our CWA should be generally less than 0.50", but some locally
heavier amounts are possible if thunderstorms make it this far
north.

Cold air advection associated with blusterly northwest winds behind
the departing low results in a cool, damp, and generally raw day on
Monday with high temperatures struggling to break 60F. A surface
ridge approaches Monday night resulting in clearing skies and
weakening winds. With 850 mb temperatures around 0C to 2C frost will
be possible Tuesday and Wednesday mornings in the notorious cool
spots. Otherwise, cool and dry weather is expected on Tuesday with
warm air advection likely to allow warming temperatures on Wednesday
and Thursday. The next trough approaches on Friday, but details
regarding sensible weather impacts are murky.
&&

.AVIATION...(For the 12Z TAFS through 12Z Saturday morning)
Issued at 717 AM EDT FRI JUN 18 2021

VFR conditions continue through the forecast. Winds will increase
this morning as the pressure gradient over the region increases,
resulting in wind gusts of 20 to 25 knots at times through the
daylight hours. Winds will relax with the approach of sunset.
&&

.MARINE...(For the 4 AM Lake Superior forecast issuance)
Issued at 503 AM EDT FRI JUN 18 2021

Southwest winds in the 15 to 25 knot range will veer to the west
today. With continued strong stability, higher platforms will see
the higher wind values. Winds up to 20 knots will continue to veer
to northwesterly on Saturday with speeds around 15 knots expected
across eastern Lake Superior as colder air wraps around a departing
low pressure system. Winds less than 20 kts are expected Saturday
night into Sunday, but another low pressure system may increase
northwest winds up to 25 knots late Sunday night through Monday.
