Marine Weather and Tide Forecast for Mishicot, WI

DISCUSSION
Issued at 110 AM CDT Sat Jun 13 2026

Early today: Scattered showers/storms

A low-level jet interacting with a mid-level zonally oriented baroclinic zone is producing fast-moving showers. Thunder is quite isolated given the meager CAPE above the freezing level.
Despite the weak instability with MUCAPEs under 500 J/kg, gusty winds of 35 to 45 mph could occur with any showers/storms. This risk should diminish after sunrise as the low-level jet weak weakens.

This Afternoon: Storm risk across east-central Wisconsin

A mid-level shortwave trough will drive a cold front southeast across the area during the day today. Once again, strong mid- level flow will support storm organization, with the frontal timing and unstable sector limiting any risk to east-central Wisconsin. However, modest low-level convergence and weak synoptic forcing and the diffuse boundary swinging through much of the area by late afternoon casts doubt on robust storm development with only 20-40% chances for a storm in the 1 pm to 5 pm window across far east-central Wisconsin. Elongated hodographs and steep mid-level lapse rates with MLCAPE forecast around 1000 J/kg would support large hail with any storms, in addition to strong, gusty winds.

Sunday-Friday: Cooler, intermittent shower/storm chances

In the wake of Saturday's frontal passage, a cooler airmass will overspread the area. Broad mid/upper level troughing will remain in place across the Great Lakes through the week, resulting in below average high temps, mainly in the 60s and 70s.

Dry weather is expected for Sunday and Monday with shower/storm chances returning for mid-week as a series of upper level shortwave troughs rotate through the base of the broader trough. At this time, the highest chances (50-80%) are focused on the Tuesday-Wednesday period, although forecast details will be better resolved in coming days. It's too early to assess severe weather potential, but broadly speaking, instability looks to be fairly weak, given the overall pattern.

AVIATION
for 06Z TAF Issuance Issued at 1039 PM CDT Fri Jun 12 2026

Confluent mid-level flow and a surface cold front are working in tandem to bring a round of showers and storms to central WI tonight.
Periods of MVFR visibility will be possible as any of these showers pass over a terminal along with slightly lower cigs down to around 5kft. As the LLJ strengthens there may be a slight increase in elevated instability which could create aid storms in producing small hail and brief 25-30kt wind gusts now through 08Z, mainly from central to far northeast WI. Precipitation should be exiting east- central WI by 12Z Sat. In the wake of the departing precip an area of MVFR status may develop across central WI early Sat morning, however, cigs should return to VFR a few hours after sunrise.

A second cold front is progged to drop across the region Saturday afternoon. This may bring another round of showers and storms to east-central WI.

Gusty winds to 20 kts are expected to redevelop by 14-16Z Sat.
