Area Forecast Discussion National Weather Service Gaylord MI 247 AM EDT Tue Jun 25 2024


- Strong/severe line of storms expected this morning. Primary hazard will be damaging winds. Large hail and localized heavy rainfall also possible.

- Conditions begin to dry as surface high pressure builds this Wednesday through the first half of the long term. Chances of showers return this weekend.

Issued at 244 AM EDT Tue Jun 25 2024

Pattern Synopsis:

A strong jet/low-amplitude shortwave will continue to punch across the Upper Midwest and over the Great Lakes this morning/afternoon as more pronounced upper troughing digs into the region later tonight.
Parent cyclone associated with forcing aloft will work across James Bay into Quebec today as the attendant front swings across the Great Lakes. Relatively high surface pressure is expected to temporarily build in later tonight into Wednesday morning.

Forecast Details:

Strong/severe storms this morning -- Primary forecast concern over the next several hours will be a line of strong/severe thunderstorms currently organizing across northern Wisconsin, with additional storms out ahead of this line working over Lake Michigan. While model guidance has struggled to handle the evolution of these storms, current confidence is that storms will trek ESE through the early morning hours along a gradient of elevated buoyancy extending over into mid-Michigan. Highest severe potential appears to lie west of Lake Michigan as these storms will encounter an increasingly unfavorable environment with eastward extent, especially over Lake Michigan and into the CWA where only a few hundred joules of MUCAPE may be in place ahead of these storms. Regardless, a sufficiently organized line of storms should carry enough momentum to bring damaging winds to parts of northern Michigan through early/mid morning -- and a severe thunderstorm watch has been coordinated with SPC to highlight this threat through 9AM at this time. Best chances for severe wind gusts will come across northwest lower Michigan in closer proximity to the lakeshores and is expected to diminish further inland. Large hail will also be possible early this morning, primarily with ongoing activity currently over Lake Michigan that lies ahead of the main line of storms still draped across northern Wisconsin. Tornado threat appears low at this time given lack of surface-based instability/low-level convective inhibition. There are also low chances for a localized heavy rainfall/flash flooding threat this morning as these storms work across northwest lower.
Quick rainfall of 1-2" per hour may lead to some impacts in city locations this morning. Otherwise, rain/thunder chances are largely expected to end by late morning/early afternoon with clearing of skies and highs in the upper 70s/low 80s.

Issued at 244 AM EDT Tue Jun 25 2024

Midlevel jet maxima spanning across the U.S/Canadian boarder with embedded height disturbances will continue active weather at times this week. Shortwave troughing currently north of the Upper Midwest will be occupying the Great Lakes region at the start of the forecast period. Conditions begin to dry through the midweek ahead of an additional trough returning chances of showers/storms towards the end of the week.

Primary Forecast Concerns/Key Messages:

-Conditions begin to dry as surface high pressure builds this Wednesday through the first half of the long term. Chances of showers return this weekend: A few isolated showers remain possible Wednesday mainly due to some lingering moisture behind the cold front at the start of the long term. Overall, weather remains pretty quiet as upstream longwave midlevel ridge pushes a cool and dry airmass into the Great Lakes region. Besides Wednesday being a little chilly in the 60s, daytime highs will remain around climatological average for the entirety of the forecast period.
Chances of showers and storms return around the Friday/Saturday timeframe as a shortwave trough currently pivoting around midlevel low pressure north of Hudson Bay progresses southward. Still a little too early to messages details, but current ensembles show no evidence of widespread severe weather or heavy rainfall at this time.

Issued at 1148 PM EDT Mon Jun 24 2024

A round of thunderstorms is expected to impact the area after 09Z, pushing quickly e and se across the area. Brief but significant restrictions along with gusty winds will be possible, with the best chance at mbL and TVC. Some lower cigs will linger for several hours after precip ends, with gradual improvement on Tuesday.

MARINE...Small Craft Advisory from 8 AM this morning to 5 PM EDT this afternoon for LHZ349.
