The Michigan Department of Natural Resources and Environment have declared Wednesday as a Clean Air Action Day for Allegan, Berrien, Cass, Kalamazoo, Kent, Livingston, Mason, Muskegon, Oceana, Ottawa, St Joseph, and Van Buren counties. This means that you should avoid activities which lead to ozone formation. Such activities are refueling vehicles or topping off when refueling, using gasoline powered lawn equipment, and using charcoal lighter fluid. Positive activities include car pooling, biking to work, delaying or combining errands and using water based paints. It is recommended that active people, and people with respiratory diseases (for example, asthma) limit prolonged times outside. There is also a Heat Advisory until midnight Wednesday Night for Berrien, Branch, Cass, Hillsdale, Livingston, Midland, Shiawassee, and St Joseph counties. Highs on Wednesday will be in the low to mid-90s, with heat indices (how hot it feels) in the upper-90s to near 100 degrees. With dewpoints and low temperatures in the low to mid-70s, it will feel very hot and humid.

SPC Shifts All of the Area Into "Slight Risk"



The Storm Prediction Center has shifted the Slight Risk of severe weather into the entire lower peninsula of Michigan with its 12:30 PM update. One storm currently (12:50 PM) between Green Bay and Manitowoc in Wisconsin may be severe in Mason and Manistee counties as it progresses eastward throughout the next hour or two. A line of storms that was trucking along earlier from Iowa and now into southern Wisconsin and northern Illinois has killed itself progressing east. Summing it up, there is a very slight chance of a strong to severe storm through about 4 or 5 PM. Our main threat of storms will enter very late this evening and into the overnight hours. Our main threats are scattered damaging winds and large hail, with an isolated tornado not out of the realm of possibility. The main stuff will be in southern Wisconsin, northern Illinois, northeast Missouri, and eastern Iowa, but a few severe storms here look to be a good possibility. We'll keep you covered throughout the afternoon into the overnight. Always check out our Facebook and Twitter pages for the latest.

Wednesday AM Forecast: One More Day of Heat

Happy Wednesday! Just one more day of this hot and humid weather to put up with. Highs today will be in the low to mid-90s, and I don't doubt some areas will get into the upper-90s. Heat indices will also be near 100 degrees. It's going to actually be a bit hotter than yesterday. Dewpoints are in the 60s today, rather than the 70s we saw yesterday, and it's easier to heat a less moist environment. There's a Clean Air Action Day today, as well as a Heat Advisory. Check for where that's for on the scrolling ticker above. We'll be under Mostly Sunny skies for a large portion of the day. Some storms moving through Wisconsin as I write this (7:10 AM) could bring a few storms into areas like Hart, Pentwater, Ludington, and Manistee as we head through the morning, but the rest of us won't need to deal with any precip until late on. A cold front will bring an end to the heat, but not before sparking some storms very late this evening and tonight. It's a pretty powerful front, knocking our temps down 20 degrees. There's a Slight Risk of Severe Weather north of a New Buffalo to Saginaw Bay line from the Storm Prediction Center. The primary threat will be Large Hail, but there's also a threat for some gusty winds and even an isolated tornado isn't completely out of the question. It is looking like a fairly marginal situation, but we can expect at least a couple severe storms. We'll dry out from north to south on Thursday. In fact, areas south of Grand Rapids could hang on to some rain through about lunchtime. Our next chance of rain will come  Friday and Saturday. This rain chance could bring a fairly decent amount of rain, with an inch or two possible. This will add to the worries on the rivers. We still have Flood Advisories for the Grand River at Ionia, the Maple River at Maple Rapids, the Portage River at Kalamazoo, and the St Joseph River at Burlington.
