Our dry warm weather pattern continues. Yesterday’s high was 87° though with dewpoints in the low 50s it wasn’t wholly uncomfortable. Yesterday’s low was 50°.
Today we will see mostly sunny skies with temperatures in the upper 80’s.
Weather History
1986: From 6 to 12 inches of rain in three days resulted in record flooding from Muskegon to Saginaw. The flooding was worsened by the collapse of several dams. Ten people were killed and damage estimates approached half a billion dollars.
On September 12, 2021, a severe storm tracked along a stationary front from Ludington to Mount Pleasant, then took a turn to the southeast and produced hailstones 2 inches in diameter near Brant Township and 1.75 inches near Chesaning.
On September 12, 1986, a 3-day period of persistent rainfall that caused the worst flooding in 50 years finally ended, which resulted in damage between 400 and 500 million dollars!

Forecast Discussion
Warm and dry through Friday The extent of any weather through Friday will be maybe some high clouds that come in on Friday well out ahead of the remnants of "Francine". Otherwise mostly sunny days/mostly clear nights can be expected. The weak trough that went by to our north on Wednesday will move away from the area to the east today. In its wake, we will see upper ridging building just west of the area with "Francine" trying to move in from the south, and another system trying to move in from the west. The building heights will allow temperatures to warm into the mid to upper 80s. However, with an southeasterly component to the flow, we will see drier dew points advect in from off of the Appalachian Mts. This means while it will be warm, it should not be too humid with dew points mainly in the 50s. As mentioned above, we could see some of the higher clouds on the northern periphery of "Francine" spread over the area on Friday and beyond. No precipitation as the cloud bases would be quite high. - The dry and very warm pattern will continue through the weekend and into next week Models continue to show anticyclonic flow in the mid to upper levels of the atmosphere this weekend and into the middle of next week. Subsidence associated with this pattern will support a dry weather. In addition, most model ensemble PWAT values into Tuesday struggle to top an inch, which is below normal for this time of the year. The ECMWF does advect in higher PwAT values Wednesday but given the lack of forcing, the potential for afternoon storms still looks low. As for the temperatures, while a few members in the various models show a potential for some 70`s next week, most are huddled in the 80`s. Based on this setup, we will keep it very warm and dry for the region. The afternoon 850 mb temperatures are generally in 14 to 17 deg C range from the models, which is supportive of max temperatures topping 80 degrees. The general east to southeast flow will favor locations near and west of US 131 for the warmest daytime reading.
Very boring weather pattern. Nothing to track right now. We will get active again at some point. Bright side is the beach communities will be hoping and getting some extra business hopefully with the extended summer.
While it has been very dry so far this month, we are still will above the record for the lowest amount of rainfall. In 1979 both Grand Rapids and Lansing only had a trace of rainfall for the whole month of September.

We now have 11 days of September 2024 in the record books. The mean at Grand Rapids is 63.5 that is a departure of -3.5. The highest reading so far is 86 on the 5th and the lowest so far is 41 on the 8th. There has been just 0.26” of rainfall that is 0.94” below average.

I didn’t realize we were -3.5 from average… that will *definitely* be changing over the next couple of weeks for sure
What below normal temps in September on top of near normal temps for the summer! How is that possible with all the warm weather hype? WOW!
Bring on some rain and a cold front!
