GOES-16 visible imagery shows a fair-weather cu field away from Lake Superior across the UP, but otherwise clear skies are over the UP today. RAP analysis shows ridging over the Plains advancing towards the Upper Great Lakes, which the negative vorticity advection is supporting a near-1020mb high pressure over Lake Superior this afternoon. With the high pressure expected to linger over the region through at least Saturday morning, no precipitation is expected.
While the main component of the wind is northerly, flow is weak enough that local influences and lake breezes are allowing for light and variable winds in some spots through this evening. Overnight, as the high shifts slightly, winds will gradually become more southerly, though should remain below 10 kt. Clear skies over the east will allow temperatures to fall to the low 40s per bias- corrected gridded MOS guidance, with some scattered skies over the west half keeping lows around 50.

The pattern becomes increasingly amplified heading into next week as a mid-level trough digging into western North America amplifies a ridge from the Great Lakes through the Atlantic Coast into eastern Canada. This pattern transition will result in much warmer, summerlike weather for Upper Mi by next week. A series of shortwaves riding over the ridge will also bring episodes of showers and t- storms heading into next week with the next best chance likely occurring Sat night into Sunday.

Dry weather continues for most of Saturday with the midlevel ridge axis sliding over the area supporting surface high pressure centered over eastern Ontario and the Lower Great Lakes. As a weak shortwave emerges out of the Central Plains, the pressure gradient tightens over the area resulting in increasing southerly winds for the afternoon with gusts to 20 mph possible for much of the UP. Cloud cover will also be on the increase throughout the day ahead of the approaching wave.

Ahead of a more prominent shortwave advancing from the Plains, sfc- 850 mb theta-e advection will strengthen on the nose of a developing 50-60kt LLJ as chances for showers and thunderstorms sneak into the western UP by early evening. PoPs will increase as showers/t-storms spread east across the forecast area Sat night into Sun morning.
Although the timing of the shortwave's arrival will be less favorable for strong/severe surface-based convection as soundings initially show weak elevated instability, the impressive lift/dynamics (0-6 km shear of 40-50 kts or higher) could still be supportive of stronger storms with gusty winds and small hail especially as one gets into the daytime hours on Sunday as instability increases. This wind/hail threat has been recognized by SPC issuing a Marginal Risk for Day 3 (Sunday). Heavy rain will be a threat as well with the stronger t-storms, as PWATs increase to generally 1.5-2 inches. Temperatures fcst in the 70s on Saturday should increase on Sunday, especially west half where there could be partially clearing in the wake of the passing shortwave. Readings over the west half should increase into the lower to mid 80s in the afternoon and this heat combined with dew points in the 60s will result in muggy and increasingly uncomfortable conditions.

Warm and unsettled weather will continue into next week. Monday through midweek, the Great Lakes will be situated between high- amplitude ridging over the Eastern Seaboard and deep troughing over the Rockies. Persistent southerly flow into the area will continue to pump in a warm, moist airmass; look for highs Monday and Tuesday to range well into the 80s for most of the area and even a few low 90s readings possible over the interior west half and in the typically warmer southerly downsloping spots. With dewpoints well into the 60s, it will get uncomfortably muggy. Given this unstable airmass and our area situated on the perimeter of the ridge, passing weak waves will leave us with chances for showers and storms both Monday and Tuesday, although mid-level capping from the dome of heat over the area could at the same time keep a lid on some of the convection. With deep layer shear still at 40-50 knots on Monday, any convection that pops that day could have a shot of going severe.
Southerly winds will noticeably increase and become gustier on Tuesday as a midlevel shortwave ripples out of the Rockies with a surface low likewise closing off and heading into the Northern Plains, leading to a tightening pressure gradient over the area.
Another strengthening LLJ of 40-50 kts may provide the lift needed for some additional convection Tuesday night into Wednesday while the surface low moves through Ontario and sends a frontal boundary across the area. From midweek onward, temperatures will trend more towards normal while the heat dome pattern governing the early part of the week breaks down, although more episodes of convection are possible Wed-Thu as more shortwaves ride along the frontal boundary lingering just to our south.

VFR conditions continue the rest of this morning through the late afternoon. However, as a low pressure approaches from the west today, expect clouds to continue to fill-in and for cigs to slowly lower from west to east throughout the day. Some calm to light southerly winds early this morning pick up a from the south after dawn into the afternoon hours. Some of the first rain showers could be seen over KIWD by the end of the TAF period, with KIWD and KCMX possibly dipping into MVFR conditions by 06z tomorrow.

We could (50% chance) see some marginal LLWS near KCMX early this morning, but given that it's so marginal and it's near dawn (when mixing and gustier winds could make it to the sfc), I'm not going to include it in the TAF at this time. We could also see some marginal LLWS at all the TAF sites come tonight, but the chances are again still rather low (30%).

High pressure ridging over the Great Lakes will lead to tranquil conditions into Saturday. Winds mainly out of the SE Saturday will be on the increase by the late afternoon, gusting up to 20 knots in the eastern half of the lake. Wind gusts to 20-25kts will be possible Sunday, then winds fall back below 20 kts Monday before increasing out of the SSE again Tuesday with maybe some gusts to 25 knots over the eastern lake. Waves should generally be below 3ft for most of the period, but are expected to increase to around 3-5ft across the eastern half of the lake Sunday.
