Yesterday we had a high of 72° and the low was 61°. We had .48 of an inch of rain minus the caterpillar I pulled out of my rain gauge (I can’t imagine how he managed to crawl in there.) We have had .59 of an inch of rain so far this month in Otsego. We will continue to see an area of low pressure move through the state today bringing occasional showers and thunderstorms through Monday. Cooler temperatures are expected as well, with highs on Monday only in the mid to upper 60s.
Sunrise today is 7:19 and sunset is at 7:57 pm.
Forecast Discussion
- Isolated to Scattered Lingering Showers Today - Showers have largely come to an end this morning as a pronounced mid- level dry slot associated with the system over southern Lake Michigan moves in. The low to our west will occlude and slowly retrograde west this morning, then will pivot back east through lower MI. Isolated to scattered rain showers at best are expected the rest of today as mid and upper level moisture is depleted. Cooler northwest flow will follow in behind the eastward departure of the expansive low pressure system. Thus, a few lingering lake effect showers will be possible early Tuesday before the last influence of the low fully exit east and surface high pressure moves into the region. - Mostly Dry Conditions to End the Week - Surface high pressure will dominate weather conditons the rest of this week with dry and stable conditions expected. Temperatures will have a gradual warming trend through this week, starting off in the 60s today and warming to near 80 by the end of the week as an 850mb thermal ridges approaches from the west. Rain chances will return near the end of the week.

You know it is Allegan county fair week so the weather is always a bit of a roller coaster. Lol
The NWS discussion mentions the potential for much cooler weather at the end of next week. That would be just in time for the start of fall :O
DISCUSSION…(This evening through next Monday)
Issued at 316 PM EDT Mon Sep 12 2022
– Cool Into Wednesday / Limited Rainfall
Our rather impressive looking storm system in the visible
satellite images is centered over SE Wisconsin at the surface but
over northern Indiana at mid to high levels. This system has
warped the cold air to the south side of it so it`s cooler over
northern Indiana and northeast Illinois than central Lower
Michigan. The rain shield around the system is falling apart as
it has used up most of the mid level moisture that was lifting
through the occlusion process. Over the next 24 hours this system
slowly move east then shear out and merge with a northern stream
system over NE Canada.
This will keep our area inside the deep cold through Tuesday and
actually into Wednesday morning. Even so, due to all of the
layered clouds associated with this system it will not get overly
cold tonight or tomorrow night (no frost/freeze just yet).
The system has used up most of the moisture it had with it, so
even though we get into what would be the deformation
precipitation band later tonight into Tuesday, I do not expect
much in the way of rainfall. It will be more like light rain
showers or sprinkles.
The upper wave that merges with our current system is currently
over central Canada near Lake Winnipeg. The upper level jet
associated with that stays north of the Canadian boarder tomorrow
into Wednesday. Nonetheless it sends a shallow cold front our way
tomorrow night into early Wednesday. Being shallow and without
much upper level support, all that will do for us is keep us
cooler longer. Wednesday should see more sunshine (jet core north
of us by then) even with that shallow cold front.
– Warming Into Weekend Then More Rainfall
Once that system gets out of the way a complex interaction between
a southern stream system and a much stronger northern stream
system (both currently over the Pacific Ocean) builds an upstream
ridge over the central CONUS by Wednesday into Thursday. The
shallow cool air will keep us cooler Wednesday but by Thursday we
will have enough southerly flow at low to mid levels to bring the
warmer air back.
Each day, into the weekend, starting Wednesday, should be warmer
than the day before it. Highs could be well into the 80s by
Saturday. However that complex interaction of the northern and
southern stream creates a progressive upper level trough that
moves slowly east into the following week. Likely we should stay
in the warm air into at least the middle of next week. However
starting Saturday but it may take until Monday, we will end up
with wiggly front near us bring periods of showers and possibly
thunderstorm. Due to the complex nature of these interacting
systems, it is to hard this point to point point how this will
work out but one way or the other we should have 3 to 5 day with
no rain.
– Recurving Typhoon Means Cooler Later
We now have Typhoon MUIFA in the western Pacific. It is forecast
to recurved into the northern stream Polar Jet by the end of this
week. Typically about a week after that happens we get 3 to 5
days of cold weather (a rossby wave interaction thing). This
would suggest much cooler air by the end of next week. There is
support on both the ECMWF and GFS for this to happen.
Nother beautiful cool Fall day outside great fire weather… INDY
We are at the time of year where it feels like we are between seasons. We kind of are because it is meteorological fall and astronomical summer. Definitely very comfortable weather
Yesterdays official H/L at Grand Rapids was 69/61 officially at the airport there was only 0.31” of rain fall, but here at my house I recorded much more at 1.52” There was no sunshine yesterday. There was a large difference in rain fall amounts yesterday with Lansing getting only 0.22” Grand Rapids officially only 0.31” Holland 1.31” my house 1.52” and Muskegon 1.69”. The overnight low here in MBY and officially at GRR was 59. At the current time it is cloudy here and 60. The average H/L for today is 76/55 the record high of 95 was in 1952 and the record low of 37 was in 1964. Today looks to be a cool day with highs only in the 60’s
