A sfc trough in the wake of departing low pressure will linger over the I-69 corridor this evening before slowly moving south and weakening during the overnight. There will be some residual rain showers this evening. For the most part, observational trends suggest ceilings will primarily be MVFR tonight. There are however areas of IFR, particularly around mbS north of the sfc trough. These low clouds are likely to linger through a good portion of the evening. Low level cyclonic flow and ample moisture should sustain the MVFR cloud bases well into the day Monday.

For DTW...West-southwest winds have increased around 10 knots and inversion heights have increased along the I-94 corridor, leading to better low level mixing. Given this and current upstream observations, MVFR ceilings will prevail through the night.


* High in ceilings below 5000 feet tonight and Monday.

Main area of rainfall associated with vorticity center will be lifting gradually northeast out of the forecast area as this forecast period begins late this afternoon. Thereafter, just expect scattered rain and/or snow showers to pivot back into the area into this evening within wraparound moisture around the base of this system. Any lingering precipitation will end by around midnight with dry conditions then holding through Monday. A slightly cooler air mass will build into the area in the wake of this disturbance with highs in the upper 30s to around 40 on Monday and lows down into the 20s Monday night.

The next shortwave disturbance, a clipper system dropping southeast from southwestern Canada, has trended a bit south as compared to yesterday and now just brushes southern parts of the forecast area with light snow/flurries perhaps mixed with sprinkles from late Monday night into Tuesday. Between marginal surface temperatures and light precipitation intensity/amounts, do not expect much in the way of accumulations, if any, from this system at this point.

Upper troughing expands a bit with the passage of this clipper with cool conditions persisting into Wednesday with highs in the mid to upper 30s. At the same time, the upper pattern shifts into a rather progressive mode with this trough shifting steadily east into late week as upper ridging expands eastward into the region. This will promote highs back into the 40s Thursday and upper 40s/50s Friday and Saturday as ridging hold in place to some degree as the next major surge of shortwave energy begins to carve out a significant upper trough to the west.

There will only be a small chance of light rain/snow showers around Wednesday night as this milder air first begins to dislodge the cooler air mass in place. Otherwise, the next potential chance for significant precipitation will hold off until next weekend. This period is highly in question as models differ quite considerably on how (or even if) the main storm system within the western trough ejects into vicinity.


Weak low pressure tracks across the southern Great Lakes today, bringing rain to the area, with a few snow showers developing over the northern part of the lake as temperatures drop overnight.
Northeast winds of 15-20 knots back to become northwest behind the low on Monday, decreasing down to 10-15 knots. Gusts will touch 25 knots at the highest, but will similarly decrease throughout the day Monday. Waves will build to borderline Small Craft Advisory criteria overnight tonight, with occasional waves of 5-6 feet being the primary concern. An Advisory is in effect for the Outer Saginaw Bay and the nearshore areas from Port Austin to Harbor Beach. Active weather pattern then continues through the week as a series of weak systems moves across the Great Lakes. Impacts still look to be relatively minor at this time, with the primary hazard to come out of these systems being repeated chances for precipitation.

Lake Huron...Small Craft Advisory until 4 AM EST Monday for LHZ421-441.

Lake St Clair...None.
Michigan waters of Lake Erie...None.
