The Storm Prediction Center (SPC) has placed west central Michigan under a marginal risk (level 1 out of 5) for severe weather Tuesday evening into Wednesday morning.
Storms are expected to develop and move northeast into Michigan after 6 p.m. Tuesday. This system is forecast to begin as a group of isolated storms but may bunch up into a line or complex later into early Wednesday morning. Storms with severe potential will likely last through the night into around 1 a.m. Wednesday.
Damaging winds and large hail will be the primary threats with this system, with probabilities ranging from 5% to 15% according to the SPC. Total rain accumulation may reach 1 inch in some places near Grand Rapids, raising concerns of flash flooding in low-lying areas. Due to the position of the warm front and lack of CAPE north of the I-94 corridor, the probability for tornadoes is limited (around 2%) for west central Michigan. Some colder temperatures north of the US-10 corridor could possibly create a wintry mix in precipitation later Wednesday morning, including the small chance of freezing rain.
