key message 1...
the upper-level trough responsible for the cooler airmass over
the region will gradually exit east into new england today as a
large upper ridge begins to expand east into the midwest and
great lakes into saturday. mainly dry and seasonable weather
will continue as surface high pressure remains across the area.
a few showers or storms are possible across far northeast ohio
and northwest pennsylvania saturday afternoon as a weak
shortwave moves east through the lower great lakes, aided by a
developing lake breeze.

temperatures will gradually warm in the mid to upper 70s today,
increasing into the low to mid-80s by saturday.

key message 2...
confidence is increasing for a few stronger storms beginning
late sunday into tuesday as several potent shortwaves traverse
the base of a strong upper-level trough across hudson bay.

there will be a couple of periods to watch for developing
storms, the first of which appears to be sunday night into
monday as a leading shortwave enters the lower great lakes,
though confidence is a bit lower given the more mesoscale
dynamics at play. slightly higher confidence exists for a more
widespread strong thunderstorm potential in the monday night
into tuesday timeframe with convection supported by the passage
of a potent mid and upper-level trough. given the favorable
northwesterly shear and anticipated linear storm mode, if any
storms were to become strong to severe, damaging wind gusts
appear to be the primary hazard. will continue to monitor the
threat over the next couple of forecast iterations.

this morning will be the coolest of the upcoming week with
widespread lows in the low 50s. it is possible that some of our
rural, low lying areas see a low in the upper 40s this morning. nbm
probabilities currently have about 20-35% chances this morning,
while chances are less than 5% for fort wayne and south bend, where
lows will be a touch higher, likely closer to 51-52 degrees.

tranquil weather continues today with dry conditions and low
humidity. high pressure current centered over the upper midwest will
slowly build across the great lakes in the coming days. dry
conditions are expected to continue through saturday with this high
pressure system eventually overhead. high temperatures today will be
a bit warmer than yesterday but still only topping out in the upper
70s! today and tonight will be great opportunities to open up
windows, with temperatures dropping into the 50s once again
overnight. lows in the 50s, while unusual from the heat and humidity
we have been experiencing recently, are not that uncommon in july.
we typically average about 5 nights with lows below 60 degrees in
july.

temperatures trend much warmer into the weekend. moisture increases
as waa ramps up, which means humidity starts increasing too. hot and
humid conditions return by sunday and monday with highs in the
upper 80s to low 90s with dewpoints in the low to mid 70s.
increased evapotranspiration from crops may also aid in locally
higher dewpoints. our forecast area will be split in between a
trough to our east and a large upper level ridge to our west.
pattern recognition tells me this is a favorable set up for a
potentially active pattern into early next week with northwest
flow aloft. a frontal system brings the next chances for
rain/storms late sunday into monday, although confidence is
uncertain on exact timing. models have been trending drier for
sunday with precipitation chances that currently sit around 20%;
monday`s chances are higher at 20-60%. any storms that develop
may be able to ride the edge of the upper level ridge through
our area. if we can get sufficent instability and moisture,
severe weather is not out of the question for sunday and
especially monday. confidence is very low given the high spread
in deterministic and ensemble model guidance.

no changes for the 12z taf forecast period. high pressure
building in across the upper midwest and great lakes regions
will allow for dry conditions and mostly clear skies with vfr
ceilings to prevail. winds will be light and variable through
this afternoon and evening.

vfr conditions will prevail through the taf period as center of a
surface high pressure drifts across the southern great lakes. this
will bring stable conditions and light winds. diurnal cumulus may
get to sct/bkn early this afternoon, but should mix out to few/sct
cumulus field late this afternoon and early evening. tonight will
carry a calm to light and variable wind and clear skies under 10kft.
expect a cirrus canopy to move over southern lower mi late tonight
and into friday. few/sct cumulus will develop again by late friday
morning.

an upper level jet streak will eject through the basal
subgeostrophic portion of eastern north america troughing today
causing significant filling of geopotential heights over the central
great lakes for the end of the week. low to midlevel temperatures
will steadily moderate over the coming days with 850mb temperatures
now at +7c to +8c rising +12c to +13c by friday evening. high
temperatures today are expected to be in the upper 70s with low to
middle 80s by saturday. strong upper level low pressure system over
hudson bay will help facilitate well organized northwest flow and
troughing over the great by late saturday and sunday.

models have been adamant in forecasting an abundance of shortwave
energy digging through lower michigan in northwest flow the latter
half of the weekend and into the beginning of next week. from this
vantage point, precipitation chances appear to be scattered during
the late weekend period with the strongest synoptic support for low
pressure arriving sometime late monday or tuesday. conditions
project to be very warm and humid sunday through tuesday with
temperatures in the upper 80s to lower 90s and dewpoints in the 60s
to low 70s.

marine...

slowly warming airmass over the next couple of days, as 850 mb temps
reach around 12 c on friday. with the center of the surface ridge
over the southern great lakes today into friday, the lightest winds
will be over lake st. clair and lake erie. even over lake huron,
wind speeds should remain predominately under 20 knots. a surface
trough slowly passing through during the weekend will bring a good
chance of showers and isolated thunderstorms, though winds are
expected to remain light.

the next notable storm system arrives on monday, as low pressure
tracks across the northern great lakes. strong thunderstorms are
possible as the cold front works through the central great lakes
during the evening hours. northerly winds behind this system monday
night into tuesday have the potential to reach and exceed 20 knots
for a period of time.
