- slight chance for rain tonight and tomorrow

Current radar has light precipitation streaming through lower michigan this afternoon. Most of if is bifurcating the region, with a band of scattered showers moving north of the i 96 corridor and a band moving along and south of the i 94 corridor. As most of the region is dry, it will take a bit to moisten up the lower levels for any rain to accumulate. Any precipitation will be falling from a cloud deck around 5 to 10kft. Soundings show fairly dry air above and below, so any rain falling will have to saturate the lower levels. All this is to say, with a lack of moisture, and while there is scattered showers possible, any rain that does fall will be light at best through the early evening. More moisture will advect in tonight, mainly after 10 PM, however while there is an increase, it remains sparse and all in told, total QPF will struggle to be measurable in most locations.

A weak, divergent trough will be squeezing its way through the upper level ridge through tomorrow. And while there is some mid level moisture which will result in some clouds, the divergent pattern and dry lower levels will keep most, if not all, precipitation at bay.

- warm and wet weather ahead

As stated in previous discussions, the pattern is changing. A deep upper trough will trek across the conus early week, making its way into the great lakes region on tuesday. A warm conveyor belt will bring moisture up from the gulf out ahead of this system, and as it moves into the great lakes the models continue to have it become more positively tilted which indicates a more progressive, fast moving, nature. Latest naefs ensembles have pwats upwards of 1.25 inches which is highly anomalous for this time of year. Capes remain fairly low so thunder is not expected. However, give the fast, moist nature of this system, a period of heavy rainfall are not out of the question. With that said, there is a concern for leaf clogged storm drains tuesday into wednesday morning. While it is fairly far out, there is the potential of 0.5 to 1.0 of rainfall in a short period of time.

Warmer than normal temperatures will continue with highs in the upper 60S to low 70S through midweek. While temperatures should drop into the low 60S through the latter half of the week, overall temperatures will be 10 to 15 degrees above normal.

Beyond the above mentioned system, the models diverge on a consensus beyond midweek. However, there is a signal for successive waves which could allow for periods of showers to be possible, currently only a 20 to 30 percent chance.

Aviation — 00Z Tafs Through 00Z Monday

Issued at 736 PM EDT sat oct 31 2026

VFR conditions are expected to dominate over the next 24 hours. We do have mid clouds in place over all of the terminals, with a few light sprinkles/showers scattered around. Ceilings are no lower than 5k ft agl, and this should be the case while this wave of showers moves through.

After 05-09Z when the showers move out, ceilings are likely to lift a bit. Dry air in the lower levels will continue to ensure this. This likely remains through the day tomorrow. The only change beyond tonight, is for a wind change to from 180 degrees with 7-9 knots around 18Z sunday.
