It’s Christmas Eve, in case you weren’t aware. I hope you are keeping an eye on the weather today too, even though it’s a holiday. You may be travelling, which would make it even more important to be appraised of the current conditions.
At 1253PM, ET, Ann Arbor was reporting a temperature of 47 degrees with rain. Low pressure centered over Ohio was producing a broad swath of rain over the Lower Peninsula at the back end of the low. The associated cold front is inundating the east coast, but swath at the back side of the system was no slouch either, particularly with heavy rain being noted just west of Ann Arbor.
As the low shifts northeast into Canada, it will begin to pull cold air into the back side of the system, creating a greater clash of air masses over the LP. This will produce very heavy rain tonight, which will transition to wet snow that will continue into the morning tomorrow. The snow can be expected to accumulate to about an inch or so on grassy surfaces, but will be too wet to really produce much accumulation on pavement. A weak surface ridge will build in on Friday, so anyone returning gifts will be able to do so with dry skies.
