AVIATION.

Elevated frontal zone will exit south of the state line between 10Z- 12Z and will take with it the low-end VFR stratus that swept across all terminal sites during the overnight period. The final concern for the TAF period will be the low-level northeast flow that is advecting moisture from Lake Huron inland. Latest nighttime satellite trends show shallow patches of IFR/MVFR cigs across the northern Thumb. Model guidance suggests lake moisture trajectories heading towards KFNT around 11-12Z, possibly making it south towards KPTK around the same time frame. This could bring a brief period of IFR/MVFR cigs between 11-13Z, with dry air advection/afternoon heating then quickly lifting any low ceilings that develop. While this is a possibility, confidence in this playing out is low and thus is only represented with a IFR/MVFR SCT group, until additional evidence is noted in satellite. Otherwise, high pressure in place today will bring clear skies to all TAF locations this afternoon and evening.

PREV DISCUSSION. Issued at 302 AM EDT Tue Sep 28 2021

DISCUSSION .

Lingering post frontal low clouds will exit south of the forecast area this morning as dry air associated with mid level anticyclonic flow and associated sfc high pressure expand into Se Mi from the north. Ongoing shallow low level cold air advection and the late September sun angle will significantly limit afternoon mixing depths. Nonetheless, full sun and the dry low level environment overhead by afternoon will support those model solutions which push mixing depths up toward 3-4k feet. This will allow highs to range from the upper 60s to low 70s, with cooler readings along Lake Huron with the onshore flow. Model RH progs suggest some mid clouds will advance from north to south across Se Mi tonight into early Wednesday, forming along the nose of an upper jet max that will track across the ern Great Lakes over the next 24 hours.

Conditions will otherwise remain very benign across Se Mi through the rest of the work week as a strong blocking pattern emerges across NOAM. Se Mi will be within the mid level confluence between high amplitude ridging over the wrn Great Lakes and a deep upper low across ern Canada/New England. This will allow a persistence of deep layer subsidence and sfc high pressure over the region through the end of the work week, allowing an extended stretch of dry weather. Limited thermal advection will hold high temps mainly in the mid 60s to low 70s, with dry boundary layer conditions supportive of cool nights with lows mainly in the 40s. Although the medium range model solutions and their ensemble members diverge this weekend, there is an overall consensus of the blocking pattern breaking down. Several members drive some increased moisture into srn Mi this weekend ahead of a wave forecast to lift into the region from the southwest. While this pattern is suggestive of an increase in rain chances this weekend, model spread still results in a relatively low confidence forecast Saturday into early next week.

MARINE .

Quiet marine conditions through today with light post frontal winds out of the northeast. A high amplitude central United States ridge with a surface high pressure building across the Great Lakes region will allow favorable marine conditions to persist through the end of the week.
