Mark Sterling, ag weather forecaster with Michigan Agriculture Commodities, referred to it as a bombogenesis – a dramatic drop of barometric pressure of 24 millibars in a 24 hour period. Centered near Sault Ste. Marie, it resulted in record rainfall Oct. 23 and 24 in various parts of the state.
Oceana County, for example, received six inches of rain on Oct. 23. Due to its timing, it likely will not impact the fruit industry, but there may be delays in field crop harvest, particularly in the northern Lower Peninsula.
“The apple harvest was done when the rain hit, and as for wine grapes, they’re not impacted,” said Kevin Robson, horticulture specialist with Michigan Farm Bureau (MFB).
Row crops may be a different story however, said Kate Thiel, field crops specialist with MFB.
"The excessively wet weather experienced in this area of the state after the elongated drought will likely postpone harvest of corn and remaining soybeans, and may cause lodging issues once harvesting resumes, negatively impacting farmers' return on investment," she said.
Some areas of the state received more rain in October than in July, August and September combined.
“The storm is all but done, but still the cold air advection over the warmer waters of the great lakes will help to keep some showers going,” said Mark Sterling. “As you get into northern Michigan, look for (precipitation) to be in the form of snow showers or a mix of rain and snow - nothing noteworthy, but still some flakes.”
Sterling predicts more sunshine with temperatures rebounding into the 50s by Thursday, before increasing cloudiness and showers return by late-Friday night into Saturday.
“Cool weather is here to stay,” Sterling said. “So say goodbye to the 70s and 80s until next year.”
