.SHORT TERM /THROUGH THIS AFTERNOON/...
Issued at 138 PM EDT Sat Jul 12 2025

Pattern Synopsis/Forecast: Negatively tilted mid-level wave is in
the process of crossing northern Michigan this afternoon with
attendant area of low pressure situated to our north over northern
Ontario. Initial lead shortwave and sfc cold front crossing northern
MI now with a secondary cold front still upstream over the central
U.P. and eastern WI. This latter boundary crosses this evening/early
overnight with higher surface pressures building in through the
remainder of the weekend.

Forecast Details: Through the remainder of the day today, still low
chances for an isolated strong to severe storm possible, primarily
over northeast lower MI where latest mesoanalysis yields 2,000-
3,000+ J/kg SBCAPE in an environment with modest deep layer shear
between 30-35 kts. Still looking at a primarily damaging wind threat
in any severe storms with continually decreasing, but still non-zero
tornado threat. Additional isolated to scattered thunderstorm
development is expected upstream in advance of the secondary cold
front over the central UP and northeast WI. Latest hi-res guidance
continues to trend this convection downward with time across
northern Lake Michigan owing to cooling mid-level temperatures and
resultant less instability. In addition, westerly low-level winds
post initial cold front should aid in limiting the amount of
effective shear for storm organization. That said, while additional
convection should be few and far between by the time it reaches the
forecast area this evening ahead of/along the cold front, a non-zero
chance for an additional strong storm can`t entirely be ruled out
into this evening across the eastern U.P. and northwest lower.

Secondary cold front expected to clear the entirety of the forecast
area later this evening/overnight with any lingering precip chances
ending. On tap for a generally tranquil day Sunday; however,
incoming smoke from Canadian wildfires will yield a hazy look versus
what would otherwise be a mostly sunny day. Some of this smoke may
translate to the surface at times with some minor visibility
restrictions possible. Some uncertainty as to the thickness of this
smoke and how it`ll translate to limiting daytime temperatures.
Current trends support maxTs in the upper 70s to low 80s.

.LONG TERM /TONIGHT THROUGH SATURDAY/...
Issued at 138 PM EDT Sat Jul 12 2025

Pattern Forecast: More zonal flow aloft expected to prevail early
this coming week before another somewhat more pronounced wave
traverse the northern tier of the CONUS midweek. A weak moisture-
starved cold front/surface trough may approach and cross the area
Monday evening/night with a more notable boundary associated with
that secondary wave crossing mid-late week.

Forecast Details: A general reprieve in active weather expected
through the early week time frame, although not without some low-end
occasional precip chances. Those chances initially arrive late
Monday/Monday evening, although likely just an uptick in clouds
given the aforementioned boundary washing out as it approaches
northern MI. Some diurnally driven pop-up showers/storms can`t be
ruled out Tuesday before more numerous precip chances arrive at
times Wednesday through Thursday.

Smoke-allowing models suggest the potential for more hazy skies and
air quality issues at least through Monday.

Warmest temperatures of the week, smoke dependent, expected Monday-
Tuesday with highs into the 80s (near 90 for downsloping locales)
before cooling off mid-late week with more clouds/showers/storms.

.AVIATION /06Z TAFS THROUGH 06Z MONDAY/...
Issued at 125 AM EDT Sun Jul 13 2025

Much of the precipitation threat has waned, with dry conditions
expected through the rest of tonight and Sunday. Brief MVFR CIGs
possible at KCIU over the next few hours, then returning to VFR,
like the rest of the terminals. Winds westerly on Sunday, gusts
15 to 20 KTs. Areas of FU/HZ tomorrow, could drop to MVFR VSBYs
in spots and at times.
