.NEAR TERM...(Through Tonight)
Issued at 222 PM EDT Sun Jul 23 2023

High Impact Weather Potential: Scattered to numerous thunderstorms
this afternoon and early evening with locally heavy rainfall rates.
Small hail possible as well.

Pattern Synopsis/Forecast: Well-advertised upper low continues to
spin across Hudson Bay this afternoon. Attendant broad troughing
anchored over the eastern third of the CONUS with upstream
ridging/impressive heat dome upstream over western CONUS. Primary
surface feature to note is a cold front currently situated from
northern Ontario southwestward through Lake Superior. This boundary
will make slow, but steady progress toward and eventually across
northern Michigan later this afternoon into tonight. Plenty of
moisture pooling ahead of this boundary, combined with diurnal
support, will aid in scattered shower/storm development this
afternoon and early evening.

Primary Forecast Concerns: Shower/storm coverage.

Generally tranquil conditions for much of the day thus far across
northern MI; however, some changes in the offing this afternoon.
Plenty of moisture evident across the Northwoods as APX's 12z raob
sampled a PW of 1.03", which near-term hi-res guidance suggests has
only increased to 1.25-1.40" early this afternoon. Robust cu field
development already underway with attendant shower/storm development
following suit...especially east of US-131. Would expect to see
additional scattered to numerous shower/storm development across
interior areas of eastern upper and northern lower...with coverage
maximized east of Interstate 75 later this afternoon/early evening.
Not much in the way of an organized severe threat given bulk shear
struggling to reach 15-20 kts, but some small hail likely out of the
strongest cells (already observed here at APX around 3:45 PM).
Locally heavy rainfall rates remain a good bet in any thunderstorms.
Localized QPF amounts exceeding an inch are not out of the question
as a result.

Any lingering showers/storms are expected to diminish with the loss
of diurnal support by mid-evening or so. Meanwhile, convection
across eastern WI and the central UP should largely erode with
eastern extent across Lake Michigan, but perhaps a couple isolated
showers hold together long enough to make a run at the northwest
lower shoreline overnight. This sets the stage for clearing skies
tonight with lows spanning the 50s area-wide.&&

.SHORT TERM...(Monday through Wednesday)
Issued at 222 PM EDT Sun Jul 23 2023

High Impact Weather Potential: Occasional thunderstorm chances
continue. Perhaps a couple strong/severe storms Tuesday?

Pattern Forecast: Broad troughing remains anchored across the
eastern one third to half of the CONUS Monday through Tuesday,
albeit with slowly rising heights. While higher surface pressures
are expected to prevail Monday through Tuesday, occasional mid-level
shortwaves, afternoon lake breeze development, and today/tonight's
boundary stalled across central lower Michigan may continue to
provide the impetus for isolated to scattered shower/storm
development.

Primary Forecast Concerns: Shower storm potential each afternoon. A
couple of strong to severe storms Tuesday?

Tranquil conditions anticipated for much of the day Monday, although
isolated to scattered shower/storm development can't be ruled out
once again during the afternoon hours given support from diurnal
processes, another passing mid-level perturbation and low-level
convergence along inland penetrating lake breezes. Do think coverage
will be less than this afternoon, but suppose a couple stronger
updrafts can't be ruled out given bulk shear increasing to circa 30
knots. Certainly some briefly heavier rainfall rates possible in any
thunderstorms. While the bulk of precip should diminish with the
loss of diurnal support, perhaps enough mid-level support works its
way in overnight to kick off a few more showers. High temps largely
in the upper 70s to mid-80s area-wide.

Rinse and repeat for Tuesday with diurnally driven showers/storms
possible once again in the midst of marginally increasing winds
aloft. Perhaps Tuesday afternoon and early evening could feature our
best shot at a few strong to severe storms given increasing shear to
near 35-40 knots, but still lots of uncertainty exists in respect to
the mesoscale details and our ability to destabilize. While SPC's
Day 3 outlook doesn't specifically highlight northern MI in a severe
risk, they do lend support to this idea with a mention of low
confidence severe chances across the Great Lakes. Highs largely in
the low-mid 80s area-wide.

By Tuesday night into early Wednesday, troughing overhead breaks
down...allowing upstream ridging to build across the Great Lakes
region. Northern Michigan expected to lie on the northern periphery
of this ridging. Increasing heat/humidity expected to be the main
story for Wednesday with highs climbing to the mid 80s to perhaps
low 90s as dew points climb to the mid and even upper 60s --
certainly resulting in a sticky/humid feel. Low confidence on any
shower/storm potential, but gut feeling supported by the bulk of
latest ensemble suite suggests lots of dry time prevails.
&&

.LONG TERM...(Wednesday night through Sunday)
Issued at 222 PM EDT Sun Jul 23 2023

High Impact Weather Potential.... Minimal

Longwave broad ridging begins to progress from the southwest into
the upper Great Lakes this Thursday through Sunday. This pattern
will support warm and increasingly humid air to occupy northern
Michigan through the forecast period. High temperatures will
climb above climatological normal for mid July, especially this
Thursday as temperatures will reach near 90 for a few areas across
the CWA. Besides heat lingering across the region for the
majority of the week, lingering moisture and daytime heating could
potentially bring enough instability to bring additional showers
and storms. Lots of uncertainties with regards to local mesoscale
effects that would cause showers and storms (lake breezes), but
will need to be analyzed with future guidance.

&&

.AVIATION...(For the 18Z TAFS through 18Z Monday afternoon)
Issued at 122 PM EDT Sun Jul 23 2023

Prevailing VFR conditions expected through the period. That said,
scattered shower/thunderstorm development anticipated this afternoon
with localized heavy downpours. Not out of the question for brief
VSBY/CIG restrictions in any thunderstorms, but confidence remains
too low to include specific mention in the TAFs. Chances diminish
near and after sunset, with partial clearing overnight.

Lake breeze development may complicate winds near Lakes Michigan and
Huron this afternoon, otherwise light southwest winds become
generally light and variable overnight.

.MARINE...
Issued at 222 PM EDT Sun Jul 23 2023

Sub-advisory conditions expected to continue on northern MI's
nearshore waters over the next several days. Occasional shower and
thunderstorm chances will continue through at least Tuesday
afternoon.
