Rainfall amounts around the state have been minimal over the past 24 hours with the exceptions of Stevensville with a report of over 5 inches, Buchanan with 1.95 inches, St Joseph with 2.83 (there is a flood advisory for that area today) and Decatur with .88. Most of the rest of the area saw trace amount to around a tenth of an inch. We had .03 of an inch here in Otsego. Below is the CoCoRaHS report for the last 24 hours.
It appears our gloomy weather pattern may hold on through the weekend. The pesky low pressure system will spread showers and even a few thunderstorms into Southern Lower Michigan into tonight. The highest probability of rain will be along and south of a Muskegon to Lansing line. Severe weather is not expected, but heavy rain is possible. This could lead to localized flooding. High temperatures today will be about 5 to 10 degrees below normal.
Low level moisture convergence increases through Saturday while aloft there is shown to be diffluence. The forecasted orientation of the rain bands will be somewhat parallel to the flow…so a few hours of training cells could occur. Thus locally more than an inch could fall where the main rain band sets up today into tonight. Currently it appears that will be somewhere south of a Muskegon to near Lansing line. This is the region where slight instability is forecasted as well so a few storms could show up. Will feature high probability of precipitation for this area today and into tonight.
