Record Cold High Temperatures

On August 13th, which was Saturday of this past weekend, a record cold high temperature day was observed for areas that were stuck under clouds and rain all day. Mount Pleasant tied the record cold high of 62°, which was originally set in 1964. It was the coldest August 13th since 1964. Elsewhere across the state, Lansing and Grand Rapids had NEVER seen high temperatures this cool in recorded history on August 13th until this past Saturday. Furthermore, these high temperatures occurred in the morning before the afternoon was rainy with temperatures in the mid to upper-50s. If it was mid-October, this would be normal, so it seems we jumped ahead two months for one day. For the middle of August, we should still be near 80°.

Typical August Weather Ahead

Your first half of the work week looks quiet weather wise. Today, the biggest story for our area will be the winds as gusts may approach 20 MPH across Mid-Michigan on this Monday, August 15th.

Temperatures are expected to be seasonal for the start of the work week. Today, look for a high near 77 degrees. Accompanied by sunshine, it looks to be a wonderful summer day for Mid-Michigan, with somewhat gusty winds reaching up to about 20 MPH. Tuesday looks to be nearly identical to Monday weather wise. Look for a high near 79 degrees, sunshine, and slightly breezy winds around 15 MPH. Wednesday will be more of the same. Look for a high near 79 and sunshine. Winds should be lighter Wednesday, with gusts closer to the 10-12 MPH range.

Lows this first half of the work week will be a similar story to the highs, nearly the same for Monday, Tuesday, and Wednesday. All three nights should feature lows in the upper 50s, with Monday’s low being near 59, Tuesday’s low near 56, and Wednesday’s low being near 58. Expect dry conditions and clear skies overnight Monday and Tuesday nights. Wednesday night will be dry as well, but expect clouds to move in Wednesday evening and overnight. Depending on who you ask, these three nights may be good open window weather. If you’d like to let in some cooler, fresh air at night, pop those windows open and welcome in those overnight lows.

Overall, the start of this week should be a lovely time to get out there and enjoy some sunshine and summer weather! With plentiful sunshine and seasonal temperatures near 80 degrees Monday through Wednesday, it will be a great time to enjoy the outdoors.

Thursday Through Sunday

We will be ending this week with some very pleasant weather for Thursday and Friday. Thursday, we will be under a high-pressure system which will keep moisture out of the area for most of the day. Later in the evening, clouds will slowly creep in. There will still be quite a bit of sun during the day on Friday. Later in the evening, the bulk of the oncoming moisture will make its way through, giving us a small chance for some nighttime showers.

Wind speeds and gusts will remain low (under 20MPH) and will come from the east. This will give way for similar temperatures across the board for both Thursday and Friday. These temperatures will be seasonal as we are approaching the final weeks of August.

Thursday’s low temperature will be around 59 degrees, just barely reaching the 60-degree mark. It will make for a very pleasant morning to maybe sit on the front porch with a cup of coffee or tea and watch the sunrise! Friday’s low will be a bit warmer with the oncoming clouds making their way to the area.

Thursday’s high temperature will be a comfortable 80 degrees. These temperatures will come with mostly clear skies. This will be a good day to go on a nice walk and maybe hit the trails! Friday will be very similar with a high temperature of 81 degrees.

Overall, the end of the work week will be very comfortable. It should make it a lot easier to enjoy the sunshine and the final days of the week!

Moving into the weekend, an upper-level low feature moves into or near the area. This will bring a chance for showers both Saturday and Sunday and perhaps a couple of thunderstorms in the mix as well. Right now, Saturday looks to be the warmer day before Sunday cools down with rain possibly developing over the top of us. Fine-tuning will certainly be needed for the weekend, but it does appear right now that we are in a pattern of weekdays being dry and weekends having rain risks.

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 the high temperature for every August 15th between 1991 and 2020 and calculate the average of all 30 values, the result would be 82°. Therefore, the normal high for today is 82°. Record high and low temperature data goes back to 1895. Sunrise and sunset data is also provided. All information is valid for Mount Pleasant.
