This is the 8-14 Day Temperature Outlook from the Climate Prediction Center for July 18-24. The highest probably of seeing warmer than average temperatures is right over the S. Great Lakes area. Most of the country will be warm to hot.
The rainfall outlook for July 18-24 shows above average rainfall from North Dakota through the Great Lakes. A large hot and dry high pressure center will be anchored over the High Plains. The northern edge of the high often features what we call the “ring of fire”…thunderstorms that form east of the Northern Rockies – move east into the Western Lakes, then southeast toward PA, MD and VA. These storms often contain strong winds, so we’ll have to keep an eye out for thunderstorms complexes moving in from the west or northwest.
Water temperatures of the Great Lakes and inland lakes will remain warmer than average for the most part and that will minimize the cooling effect of the lake-breeze. Thunderstorms that might tend to weaken over colder lake water may hold together because of the warm conditions.
24-Hour rainfall totals as of 8 pm Friday: Detroit 2.05″ (daily record), Lansing 1.42″ (daily record), Ionia 1.27″, Jackson 1.11″, Grand Rapids (airport) 1.07″, Holland 0.72″, Ionia 0.71″. There were several small areas of wind damage from the storms…one along US 131 from Byron Center and Cutlerville up to the near NW side of G.R. and another along M-57 near Greenville. Several locations reported small hail.
Severe storms should stay just to the southwest of Michigan this afternoon. There is a large Slight Risk Area from Iowa to Arkansas with the primary threat being wind damage.
Here’s a map showing the severe storm reports in the U.S. on Friday. Here’s severe reports from SE Michigan Friday PM. 3″ of rain fell in Montrose and in Burton.
