The tropical-like weather of the past few days, with scattered afternoon showers and storms, will slowly dwindle over the next couple of days, but that may still be enough for a few more localized downpours, especially Thursday. Over the Memorial Day weekend, the weather will become influenced by a dome of hot, dry air building in the Upper Midwest and Great Lakes region. This will likely push temperatures well into the 80s and some 90s in our region for the holiday weekend. Because we are not underneath the core of this high pressure system — its location depicted well by the location of the hottest temperature anomalies on Sunday morning on this European model map (remember, these numbers are Celsius, so the peak heating area depicted in and near Michigan of 13 degrees is more than 20 degrees Fahrenheit above normal) — there may still be a few scattered showers and storms as daytime heating and terrain effects create lift that may not be entirely checked by warm air aloft. But coverage and overall intensity are likely to be much less than the last three days and that of Thursday. There are many signals this pattern entirely reverses by late next week, so that cooler air is centered over the East and hotter weather settles into the West.
