DISCUSSION...

Weakening flow and increasing subsidence has effectively cleared the lower stratus from earlier as surface high pressure rolls through Michigan. Light northwest flow has allowed for lingering lake moisture and diurnal stratocu this afternoon which should scatter out this evening into tonight. Limited clouds tonight and the continued snow pack will help low temperatures tonight drop to the lower teens.

Surface high pressure and 850mb ridge will pass to the east tomorrow morning bringing a stretch of weak warm advection with deeper southwest to west lower level flow. Temperatures at 850 mb will gradually warm towards 0C Friday and Saturday, eventually topping 0C on Sunday. This slight warming trend will bring daytime highs to the upper 30s and low 40s for tomorrow and Saturday with Sunday up towards the mid 40s. Guidance continues to point towards dry conditions holding through the weekend with southeast Michigan residing between northern stream and southern stream systems. The stronger of the two being the southern stream moving across the Gulf states with the associated northern end of precipitation likely only reaching the Ohio Valley. The northern stream looks to hold north of Lake Huron.

Greater warm advection enters the region early next week as west coast troughing pushing into the plains with afternoon highs Tuesday possibly achieving the 50 degree mark. The leading ridge should keep conditions dry through bulk of the Monday and Tuesday stretch. Increasing moisture will arrive and set the stage for the next chance at precipitation, possibly as early as Tuesday night. Greatest chances likely for Wednesday as a low pressure system organizes along baroclinic zone under left exit region jet dynamics. Current forecast of low pressure track and temperatures would bring rain as the dominate p-type.

MARINE...

An area of high pressure will affect most of the central Great Lakes through the weekend. A clipper system is expected to cross the northern Lakes on Friday bringing slightly stronger winds and a bit of snowfall to northern Huron. Southwest winds of 15-20 knots will prevail with gusts AOB 25 knots. The gradient relaxes Friday night, after the system exits eastward, then trajectories veer WNW Saturday morning. A secondary surface high passes over Lower Michigan on Saturday leading to weak and variable winds. Winds then back southerly with time. Lighter flow continues Sunday while a weak frontal boundary turns weak prevailing flow westerly Sunday evening. A split-flow configuration keeps winds AOB 15 knots early next week with minimal opportunities for precipitation.
