4Warn Weather – Storms are moving across Southeast Michigan Thursday, but quieter weather is on the way before summer heat makes another comeback.
Scattered to numerous showers and thunderstorms developed ahead of a slow-moving cold front. The storms will continue moving from west to east through the evening.
Some storms could bring heavy downpours, frequent lightning and gusty winds. An isolated strong to severe storm is possible, with wind gusts of 40-60 mph and rainfall rates over an inch per hour in the strongest storms.
This is not expected to be a repeat of last Friday’s severe weather outbreak that brought widespread damaging winds and knocked out power to hundreds of thousands of customers across Southeast Michigan. The damaging wind threat Thursday is isolated.
The timing of the storms could impact evening plans, including the final game of the series between the Detroit Tigers and Athletics at Comerica Park. First pitch is scheduled for 6:40 p.m.
Temperatures will be near 80 degrees around the start of the game, but fans should prepare for the possibility of a passing shower or thunderstorm that could cause interruptions.
The storm threat gradually decreases Thursday night as the cold front moves south.
Friday
A few showers and thunderstorms remain possible Friday, especially south of M-59, but the weather pattern improves heading into the weekend. Highs will be near 80 degrees north of I-69 and near the Lake Huron shoreline. Expect highs in the mid-80s near Detroit, Ann Arbor, and Monroe.
Weekend
Canadian high pressure moves in, bringing lower humidity, more sunshine and comfortable July weather. Highs will stay near normal, mainly in the lower to mid-80s Saturday and Sunday.
The break from the heat will not last long.
Workweek
A new heat wave could develop next week as temperatures climb to near 90 degrees Monday and into the lower 90s Tuesday and Wednesday.
A heat wave is defined as three consecutive days with temperatures of 90 degrees or higher.
While the heat and humidity will increase, the setup does not look as extreme as the dangerous heat Southeast Michigan experienced leading up to the Fourth of July weekend, when heat index values topped 105 degrees.
