- Next chances for more widespread rain arrive Wednesday/Thursday

.SHORT TERM /THROUGH MONDAY/...
Issued at 223 PM EDT Sun Jul 13 2025

Pattern Synopsis/Forecast: Low-amplitude upper trough continues to
cross the western Great Lakes through the remainder of the day with
flow becoming more zonal through at least midweek. Surface high
pressure will largely remain in place through this same time frame.
However, a weak frontal boundary/surface trough will cross the area
on Monday, perhaps with at least a brief uptick in cloud cover and
low chances for a few showers.

Forecast Details: Plenty of wildfire smoke aloft resulting in
hazy/smoky skies this afternoon with occasional reductions in
surface visibility. Otherwise, little in the way of sensible weather
anticipated through tonight with lows falling into the 50s and low
60s area-wide.

Early Monday, decaying frontal boundary with limited large scale
ascent will approach from the northwest. While inconsequential
overall, an uptick in cloud cover and perhaps a couple of rogue
showers will be possible across eastern upper and the tip of the
mitt -- primarily mid-Monday morning through mid-afternoon.
Smoke concentrations expected to be less than today, but still
some haziness anticipated tomorrow as well. Highs in the 80s
area-wide.

.LONG TERM /MONDAY NIGHT THROUGH SATURDAY/...
Issued at 223 PM EDT Sun Jul 13 2025

Pattern Forecast: By midweek, broad upper-level troughing expected
to be evident across much of Canada into the northern tier of the
CONUS while ridging begins to build over the southeast states.
Plenty of moisture transport into the nation`s midsection,
including the Great Lakes, by this time frame on the heels of
increasing southwesterly winds. Attention revolves around a
quasi-stationary W- E oriented boundary expected to be draped
from Quebec into the northern Plains mid-late week, providing
the focus for surface waves to ride along and repeated rounds of
showers and storms.

Forecast Details: While confidence is high in more active weather
returning across the Midwest and Great Lakes mid-late week, lower
confidence prevails with respect to the details and potential for
repeated rounds of convection/heavy rain. Confidence in the latter
largely hinges around placement of that nearly stalled W-E oriented
boundary and how long its parked over the same region before being
shunted off to the east. Where it does set up, repeated rounds of
showers and storms are likely with locally heavy rain possible given
ensemble means suggesting PWATs in the climatological top 25th
percentile for mid-July. WPC noting this potential as well with all
of the upper and mid-MS Valley, and Great Lakes highlighted in a
Marginal Risk for excessive rainfall.

By Friday, higher probabilities prevail for quieter weather with
high pressure at least briefly settling over the region. Confidence
diminishes thereafter with a myriad of solutions possible heading
into next weekend.

Otherwise, very warm temperatures anticipated Tuesday -- potentially
into the low-mid 90s in favored downsloping areas, but some question
as to whether upper-level smoke lingers and limits daytime heating
to any extent. Potential warmth and mugginess continues Wednesday
with cooler temperatures expected through the remainder of the
forecast period.

.AVIATION /18Z TAFS THROUGH 18Z MONDAY/...
Issued at 130 PM EDT Sun Jul 13 2025

Smokey/ hazy skies have been impeding visibilities across most
terminals this afternoon with upstream observations continuing
to display reduced visibilities. Thinking MVFR visibilities
will continue through the day and possibly into tonight/ Monday
as Canadian wildfire smoke tracks overhead-- This will continue
to be monitored and fine tuned. Winds will breifly shift more
south- southwest late tonight into early Monday before switching
back westerly Monday with occasional gusts 15 to 20 knots.
