Severe storm threat over Detroit, muggy weather reaches new level

4Warn Weather – Humidity continues to be an inconvenience for residents of the Detroit metropolitan area, but possible strong storms could also cause headaches.

In many communities with a lot of moisture in the atmosphere, temperatures will not fall below 70 degrees at night. These conditions will favor possible thunderstorms, including some with heavy rain, gusty winds and hail. The storms are expected to hit southeast Michigan during the overnight hours between about 1 a.m. and 6 a.m. The risk is at level one, or low, but it is important to have multiple ways to receive warnings.

Wet roads and puddles could impact commuter traffic Monday morning, but showers and thunderstorms are expected to subside before noon. In the afternoon, it will clear up and skies will become partly cloudy to mostly sunny. Temperatures will climb to near 90 degrees, with heat indices between 90 and 100 degrees. These conditions will again help strong storms develop late. A non-thunderstorm wind will be from the west-southwest at 6 to 12 mph.

Strong to severe storms are possible across southeast Michigan Monday night into Tuesday morning. The exact timing is uncertain, but they are likely to develop after midnight. The chance of severe weather is slightly higher west of I-275. Warm lows will be below 70°F.

Tuesday

There is a chance of showers and thunderstorms developing near a cold front that will move across the Great Lakes region on Tuesday. Some storms could cause gusty winds in areas, especially near Monroe and further south. Temperatures will reach the low 27 degrees, but it will feel hotter. Lows will drop to the mid 18 degrees.

Wednesday

Behind the cold front, cooler and drier air will be noticeable on Wednesday. Maximum temperatures will be between 24 and 27 degrees until next weekend. After a wet start to the week, a high pressure area will bring plenty of sunshine.

Flood warning

The rain could worsen flooding on the Huron River in Livingston County. A flood warning remains in effect for the river, which experienced moderate flooding on Sunday.
