Mid

Early in the week, we begin our work week in July with plentiful sunshine. A series of low pressure systems moves through the area throughout the week, providing us with chances for rain, potentially widespread across Lower Michigan. Wednesday and Friday look to be the rainiest days of the week. Given widespread drought across the mitten, this will hopefully be welcome news for your lawn and garden. Precipitation regardless, high temperatures in the 70s and 80s look to be in the forecast for the early work week.

Thursday, we will return to high temperatures near 80°F and low temperatures in the mid-60s. Partly cloudy skies are expected, with winds shifting from northeasterly to southerly at 5 mph. Heading into the weekend, high temperatures are expected to remain in the upper 70s, with lows in the mid-60s for Friday. Cloud cover is expected to increase to mostly cloudy Friday morning. Chances for showers and possible thunderstorms will increase throughout the day, Friday as a low-pressure system makes its way into the area. These showers, with their accompanying clouds, will likely move out of the area Saturday morning, leaving mostly sunny skies for Saturday afternoon. Expect high temperatures in the low 80s, with lows in the mid-60s for Saturday. Mostly cloudy skies will likely return for Sunday, with chances for isolated showers early Sunday morning. High temperatures for Sunday and Monday are expected to be in the upper 70s, with low temperatures near 60°F. Expect partly cloudy skies and isolated showers to start off the workweek.

The low temperature of 81°F in Grand Rapids on this day was the warmest low temperature ever recorded there. The temperature in the upper-90s in the afternoon combined with high humidity to produce heat index readings near 120°F, some of the highest ever recorded.

Morning Sun AlmanacJuly 10 – July 16, 2023

Mt. Pleasant Almanac for This Week:Almanac information is a way to look at normal and record high and low temperatures for this time of year. The normal temperatures are based on the 30-year average high and low for that date between 1991 and 2020. For example, if you take all the high temperatures for every July 10th between 1991 and 2020 and calculate the average of all 30 values, the result would be 84°. Therefore, the normal high for today is 84°. Record high and low-temperature data goes back to 1895. Sunrise and sunset data are also provided. All information is valid for Mount Pleasant.
