We now begin the last month of met summer with a more rapid loss of daylight as we progress through August.
We had 3.79 inches of rain in July and 12.79 inches for the summer thus far (in Otsego).
Sunrise is 6:35 today and sunset is 9:02 pm. We have a loss of two minutes per day of daylight this week, By the end of the month the sunrise/sunset times are 7:07 am and 8:20 pm. Our grandkids start school in a couple of weeks (August 16th from what I am told), which seems early this year. With Covid messing up last school year maybe they want to get a jump on in-class learning.
We don’t have a big expectation of rain today west of US 131, though chances are greater further east especially in the Detroit area on up into Bad Axe. It appears this week will be dry with high pressure dominating the state. North winds will be a little gusty today and will create dangerously large waves and strong currents at Lake Michigan beaches. Calmer weather and wave conditions are expected Monday through Thursday.
- Life-threatening waves and currents at Lake Michigan beaches today Wave heights will increase quickly after sunrise, building between 3 and 6 feet by late morning. The large waves and strong currents will make swimming dangerous at West Michigan beaches south of Manistee. Conditions will be especially rough on the north sides of piers. Most drownings in the Great Lakes occur when waves are between 3 and 6 feet. The large waves will diminish steadily after sunset, and expected to only be about a foot high on Monday. - Few showers and thunderstorms redevelop today Showers and thunderstorms that developed ahead of a surface trough dropping through the area were close to exiting the CWA at 3 AM. We likely saw wind gusts 40-50 mph from these storms prior to 1 AM, but storms weakened quickly after that. Cold front/northerly wind shift will continue to work southward through Lower Michigan early this morning, and we could see a few more showers before it passes through. Additional showers, and even a few thunderstorms, are expected across Lower Michigan today, with the highest coverage expected during the afternoon and early evening. Upper trough will pivot down through the area adding forcing, while lapse rates steepen as upper cold pool passes overhead during peak (surface) heating. The coldest air aloft will pass just to our east, and should provide a better coverage of showers/storms over the eastern part of the State. Forecast soundings actually show a fairly low potential for rain in Grand Rapids and Kalamazoo, as we see drier air arrive and thermal recovery in the mid-levels right as the lapse rates really start to steepen during the afternoon. Any thunderstorms that do form will have a higher than normal chance to produce small hail, as freezing levels dip just below 10 kft. - Refreshing with below normal temperatures early this week, then warming High temperatures in the 70s and dewpoints in the 50s (not humid) will continue our stretch of refreshing weather through Tuesday. Normal high temperatures for early August are in the low 80s. Upper troughing responsible for the cooler temperatures will shift out of the area for the second half of the week, with highs warming back into the mid 80s Thursday through Saturday. Dewpoints and humidity will also come up noticeable by Saturday. - Mainly dry for the upcoming work week Beyond today, the forecast looks mainly dry as surface ridging becomes more dominant.
