Pleasant Week Ahead

Yesterday we managed a whole .04 of an inch of rainfall which brings us to 2.23 inches for the month in Otsego.  Our high temperature was 67° with a morning low of 54°.  Today we’ll see an increase in cloud cover for the afternoon, but skies will clear tonight. Temperatures this afternoon warm up into the mid to upper 60s and fall tonight into the low to mid-40s. Tuesday will be similar to today but highs will be a little warmer around 70.   We will remain mainly dry for the week with slim chances of rain on Tuesday night into Wednesday (around 20%).  A warming trend is in store with temperatures rising to around 80° towards the end of the week.

Grand Rapids Forecast

9 17 grr

U.S.A and Global Events for September 18th:

1926: The great “Miami Hurricane” produced winds of 138 mph that drove ocean waters into the Biscayne Bay drowning 135 persons. The eye of the hurricane passed over Miami, at which time the barometric pressure reached 27.61 inches. Tides up to twelve feet high accompanied the storm, which claimed a total of 372 lives.

1941: One of the greatest aurora borealis or northern lights ever observed in the central Atlantic and mid-central portions of the U.S. occurred on the night of September 18-19th. The displays continued from twilight until just before dawn and were observed as far south as Florida and southern California.

Forecast Discussion

A high pressure ridge will gradually build in today and bring
pleasant wx with partly cloudy skies and seasonable temps. Patchy
early morning fog will dissipate by mid morning and high temps
will reach the mid to upper 60s.

Min temps tonight will range from the upper 30s up north to the
lower to middle 40s across most of our area with mostly clear
skies and calm winds resulting in excellent radiational cooling
conditions. Patchy radiation fog is expected to develop during the
early morning hours Tuesday.

An upper level disturbance will move ese from the upper midwest
Tuesday and bring some cloud cover along with potential for
isolated light rain showers. However the vast majority of our area
will stay dry with no measurable rainfall Tuesday given sfc
ridging and a dry airmass still in place until better moisture
advection begins Tuesday night. It will be slightly milder
Tuesday in spite of more in the way of cloud cover than today as a
result of sfc winds becoming southeast to southerly.

Tuesday night 850mb to 700mb warm air advection kicks in along with
the low level jet. Precipitable water values also increase to around
an inch. Soundings show there is a bit of dry air below and above
the saturated layer, but with the different sources of lift in place
along with the increased moisture feel that it is still worthwhile
to keep the 20-40 percent probability of precipitation values in the
forecast. Best chances for showers will be west of US-131 and along
the lakeshore. Other than a slight chance (20%) for showers to
linger along the lakeshore Wednesday afternoon, dry conditions are
expected through most of the week. As we head into next week the
confidence drops as there are varying solutions with a closed low
and how it will evolve. Ensembles show this spread in the QPF, but
there is more confidence in temperatures this week as most of the
guidance hones in on temperatures warming up to around 80 for
Thursday through Saturday.

We received zero precip yesterday. Our lawn is still lush and green. In fact other than a few leaves here and there, everything is still very green – and we’re in the 2nd half of September. It’s going to be another windows open kind of day. Enjoy!

I think we have less than 0.5” for the month. It’s been a dry 3-4 weeks. I hope we get some rain next weekend. Although it’s still green I am seeing some clear signs that we could use some rain.


The official H/L yesterday at Grand Rapids was 68/54 there was no rain fall. The sun was out 14% of the possible time. There were 4 HDD’s and the highest wind speed was 17 MPH out of the N. For today the average H/L is now down to 73/52, the record high of 94 was set in 1906 and the record low of 35 was set in 1973. The record rain fall amount of 0.86” fell in 1911. Last year it was still a summer like 82/65 and there was 0.14” of rain fall. At the current time I have… Read more »


The week ahead will start off on the cool side today and then warm up to a little above average for the end of the week and weekend. The highs today will be in the 60’s and then we should see temperatures in the upper 70’s to around 80. Lows tonight will be in the 40’s before rising to the upper 50’s All in all a rather nice late September week.
