Issued at 127 PM EST Tue Nov 10 2026 - Turning colder; rain showers Wednesday Skies are clear and temperatures are well in the 60s...over 10 degrees above normal. A cold front moved across the cwa earlier today and highs tomorrow will be below normal in the mid 40s. High clouds will begin to filter in tonight ahead of the next clipper. - Lakeshore rain/snow showers Thursday night We`re moving into a pattern that will have a taste of winter with it. A clipper currently over the intermountain west will take a track toward northern IN by Wednesday afternoon. This clipper will be the start of a huge upper low development. Light rain showers are expected Wednesday afternoon as the surface low arrives, but qpf looks limited to around a tenth of an inch. Meanwhile, as the clipper moves east, strong north flow will develop behind it and draw another short wave south from Canada. The main dynamics will remain over the lake and so we`ll have highest PoPs near the lake shore Thursday and Friday. Lake effect rain and snow showers are going to develop as h8 temps fall to -6c, creating lake delta t in the mid teens. If any snow falls, it`s likely to be over the northwest cwa Thursday night. Air temperatures Thursday and Friday will be too warm for snow. However, the air may be cold enough for some light snow Thursday night near the lake shore south of LDM. A few tenths of an inch of snow are possible. However, there`s a 50% chance of an inch or two and a 30% chance of around 3, generally between Hart and Ludington. The upper low is progd to shear out by Saturday leading to a dry weekend. Temperatures will remain chilly through the weekend with highs in the 40s. A slight moderation in temperatures occur early next week when highs approach 50 as ridging moves overhead. && .AVIATION /18Z TAFS THROUGH 18Z WEDNESDAY/...
