Yesterday Slim bid farewell to meteorological summer and gave us a lot of great data on the fall season (great post Slim).
The NWS will post the summer data today or tomorrow (maybe), I can post the rainfall data for Otsego for the summer months. We have gone 14 days with only .12 of an inch of rain, which gave us 3.27 inches for the month of August (all in the first two weeks). We ended up with 12.48 inches of the summer months.
Our highest temperature came on August 26 which was 94.5° and the lowest was 42.6° on June 11 at 6:11 am. Our highest dewpoint was 83.2° on August 27. In my humble opinion, this was a perfect summer all in all.
Weather History
1953: A heat wave that began in late August continued into September, with record highs of 97 degrees at Grand Rapids and 96 at Lansing. The 95 degrees at Muskegon tied the record high for the month there.
2009: September begins with temperatures more typical of October. Lows include 41 degrees at Muskegon, 36 at Ludington, Hersey and Baldwin, and 35 at Harrison. Cadillac fell to 32 degrees for the second morning in a row, and Leota in Clare County fell to 30 degrees.
2018: Four tornadoes occurred within a two-hour period during the evening. The first was a brief tornado that snapped trees near Gull Lake in Barry County. This was followed by a tornado with winds estimated at 100 mph that destroyed a manufactured home at Morley in Mecosta County. Two other tornadoes took down trees, some of which fell on houses, in Jackson and Clinton Counties.

NWS Forecast
Forecast Discussion
- Cooling Trend Through Labor Day In this cooler and drier weather pattern, the main weather-related hazard will be dangerous waves and currents on Lake Michigan today. See the Marine section for more details. The base of a synoptic upper-level trough is passing through the northern Great Lakes this morning. A surface cold front with a distinct wind shift can be tracked northwest to southeast through Lower Michigan this morning. 850 mb temperatures will drop several degrees C through the day, and full mixing from surface to 850 would support highs in the lower 70s in central MI and mid-upper 70s in southern MI, on the cooler side of normal for Sept 1. The air will be drier and more comfortable with dew points in the 50s and 40s. There may be a few clouds passing through but overall the forecast soundings are quite dry. Lows tonight drop into the 40s in many spots, with a chance of some patchy ground fog as winds just near the surface go light. - Dry into Mid Week then Chance for Rain Late in the Week Surface high pressure will remain entrenched across the Great Lakes region from Monday night into Thursday. Ridging aloft will be in place as well which will results in high confidence in a dry forecast. The pattern begins to change late in the week as upper troughing digs towards the Great Lakes from the Northern Plains. A cold front is forecast to move through the area Thursday night and Friday when rain showers and a few thunderstorms will move through the area. Into the weekend the evolution of the pattern is much more a low confidence forecast as the operational models have different solutions. The ECMWF is progressive with the front, while the GFS develops a second low in the Plains. As of now we have chance pops (30-50%) in the forecast for the end of the week and isolated pops (20%) over the weekend. - Moderating Trend in Temperatures Through the Week Temperatures will slowly moderate this week to back to near normal levels by Wednesday and Thursday. Highs will be in the lower 80s both days. After the frontal passage however, temperatures will tumble once again. Highs will cool into the 60s next weekend which will be a taste of fall.
So long Summer no air conditioning no fans tonight let’s celebrate welcome to Fall….INDY
