We still have plenty of low-level moisture in place, and a weak trough or front is rotating through the area each day this week.
We will continue to see a chance for spotty showers and thunderstorms during the afternoon and evening hours today, Thursday and even Friday.
The instability necessary to fuel rain and storms will diminish after sunset as peak heating fades.
At this point, a strong southerly flow will bring warmer and more humid air this weekend with highs well into the 80s with another chance for rain and storms late Sunday.
Severe weather swept through Metro Detroit last night producing an EF-0 tornado. The tornado touched down in Taylor (Wayne County) with damaging winds gusting to 80 mph.
The path was less than a mile long and 100 yards wide (NWS survey: https://bit.ly/2KiOwCL). The tornado was on the ground for 2 minutes (12:44 am - 12:46 am).
This is the first tornado reported in Metro Detroit this year. Southeast Michigan averages 5-6 tornadoes per year.
As this cluster of thunderstorms lifted northward last night, it also produced flooding rain inundating streets and storm drains.
Around 3 inches of rain fell in just over an hour across parts of Metro Detroit. Detroit Metro Airport tallied 2.96" on July 31st.
This is the most rainfall recorded in a single day this year!
Meanwhile, the 24-hour rainfall reported for Detroit came in at a whopping 4.07" (NWS reports: https://bit.ly/2n0RGSv)
