We have some cooler air filtering in today and through the weekend. The daytime highs will be in the 60s to near 70°. Lake-induced cu clouds will develop with the breeze coming off Lake Michigan bringing a chance of a stray shower, especially tonight into Saturday. Cumulus (CU) clouds often appear in the morning and disappear in the evening. If conditions are unstable, cumulus clouds can turn into (CB) cumulonimbus clouds. Cumulonimbus clouds are powerful and develop vertically. The base is often dark due to the density of the water droplets that make it up.

1994: Cool weather prevails for several days with low humidity and high temperatures only in the 60s. Record cool maximum temperatures are observed at Grand Rapids and Lansing, where the high on this date is only 64 degrees.
2009: A thunderstorm brings damaging downburst winds estimated at 70 to 75 mph to Muskegon County. The storm strikes Hoffmaster State Park and Fruitport, downing dozens of trees and causing some damage to homes. The storms continue into Kent County, hitting Kent City and Sparta. Another severe thunderstorm produces a downburst that blows part of the roof off a school in Jackson.
On August 9, 2009, numerous roads were flooded and closed. The most significant road damage was M 53 south of Imlay City which was washed out and had to be closed for about 10 days. Over two dozen homes were also damaged due to the flooding. A local state of emergency was declared. Five to eight inches of rain falling within a 30-hour period led to widespread flooding across southern Lapeer County. A few reported rainfall totals include 7.4 inches in Almont, 6.3 inches in Imlay City, and 5.65 inches in Lapeer.
Also on August 9, 2001, a heat wave from the 5th through the 9th, resulted in temperatures pushing well up into the 90s. On the 6th, the excessive heat caused at least 200 people to seek medical attention. The heat wave peaked on the 8th when temperatures reached a record high 99 degrees.

Forecast Discussion
- Cooler With A Few Showers Tonight And Saturday WNW winds will advect a cooler and drier airmass into our area today with a fair amount of stratocu developing due to increasing lake induced instability as h8 temps fall to 8 to 10 C by this evening. High temps today will only reach the low to mid 70s given brisk wnw flow caa and some cloud cover. Lake induced instability increases some more tonight into Saturday as h8 temps fall to 6 to 7 C tonight. Therefore we expect isolated to scattered showers to develop mainly for tonight and Saturday. High temps tomorrow will only reach the upper 60s to lower 70s with extensive stratocu and brisk west flow cool air advection. - Dry pattern with near normal temps returning next week No noteworthy precipitation events are foreseen for the next week. Temperatures will rebound to near normal values next week but humidity levels will remain in the comfortable category. Upper low/H5 troughing is slow to depart the region over the weekend into early next week but the air mass remains quite dry. Any showers related to shortwaves/sfc troughs rotating through would be light with only limited coverage. A large area of sfc high pressure eventually dominates our weather most of next week with no appreciable moisture return expected. Partly clouds skies generally prevailing.
And just like that…Sunmer is gone in the Southern Arctic.

The below normal temp pattern keeps rocking! We are entrenched in long term below normal temp pattern this summer! Who would have thought? Wow, just wow, WOW!
At this point this summer has had a near average mean temperature with fewer than average “hot days”

Fantastic summer so far. Only one heat wave and plenty of sun and precipitation. Not much to complain about this summer.
