Chance of Storms Today

Yesterday we had a high temp of 81° and a low of 51° with 100% sunshine.  We are currently at 63° at 7:30 this morning.

Today, we have an Air Quality Alert for Muskegon, Ottawa, Kent, Allegan, and Van Buren Counties along with southeastern Michigan.

Southern Michigan from Grand Rapids to the south is under a slight risk area for severe storms today:

Scattered thunderstorms are expected from late this afternoon into early tonight. Most of these storms are not likely to be severe, however, a few of the storms could produce damaging winds, large hail, and brief tornadoes.


Expect a period of showers and isolated thunderstorms to cross Southwest Lower Michigan from late morning into the midafternoon. The stronger storms, the ones that may have damaging winds, large hail, and isolated tornadoes would cross the area this evening. Meanwhile, a complex of thunderstorms, that developed in Nebraska is expected to head just south of Chicago by early afternoon before weakening. That complex of storms is not expected to impact our area.


Forecast Discussion

--Showers/storms possible today--

Latest sfc analysis shows a cold front stretching from northwest WI
southwest to eastern NE. This front will move east to a Alpena to St
Louis line by 00z. The front is being pushed east by a fairly strong
short wave that digs southeast across northern Lower by 06z. Ahead
of the front, models are painting fairly robust instability over the
southern cwa with SBCAPE around 2500 j/kg; much less farther north.
Bulk shear values are around 50kts or better through 06z.

There looks to be two areas of precipitation today. The first will
cover the northern part of the cwa and be associated with the exit
region of upper jet and digging short wave. this is also the area
where moisture transport vectors increase. Instability is a little
less in this area, but still capable of producing a strong to severe
storm.

The second area of precipitation looks to be along/south of I-94
later this afternoon and this evening. This area has a little more
going for it in that the cold front will be moving across Lake
Michigan around this time. The NSSL WRF, ARW, FV3, and Nam Nest
develop storms generally along/south of I-94 after 23z today. This
is also the area where the LLJ will maximize along with the entrance
region of the upper jet. Precipitable water values are also highest
here today. A lot of dynamics are in play and threats include strong
winds, perhaps some hail, along with heavy rain.

Unfortunately, the central CWA, where in some places a moderate
drought is ongoing, may see the least precipitation.

By midnight, much of the showers/storms will be east of the cwa.
Another weak short wave will help to carve out the upper trough over
the western Great Lakes Tuesday and the instability associated with
the cooler temperatures aloft may help to generate a few showers,
mostly over the northeast cwa.

--Mostly dry the rest of the week--

High pressure builds in at the surface Wednesday. As the upper
trough moves east and ridging develops overhead, temperatures will
climb into the mid 80s again, but humidity will be keep on the lower
side due to sfc dewpoints in the lower 50s.

--Next chance of rain arrives Saturday--The upper ridge axis will
remain west of the region through the end of the week. that will
allow another short wave to travel through the Great Lakes early in
the weekend. Perhaps we`ll see some rain from it. The GFS has a much
stronger wave than the ECMWF does and consequently produces a lot
more rainfall. However, it`s still a week away.

Pretty impressive line segment currently over the lake. About to impact Oceana County near Silver Lake Sand Dunes

The storm offshore Muskegon sure is strong. Whether or not it maintains strength is a different story. Nice hail core a few moments ago AND rotation.

Both local TV Mets are calling for 90s every day next week. I’d rather keep it just like this.

Decent rain just North of us and just South of us, barely anything here, hardly got the ground wet. Farmers are going to have a real problem if we don’t get some decent rain soon. Looking like nothing but more hot and dry air on the way in the outlooks.

We had just a couple of sprinkles this afternoon. It is crispy here too.

The rain looks promising when it was on the lake. Dark reds, lots of lightning. Then poof! It fell apart coming ashore.

Yeah I was watching and hoping but like you said, “poof”, it was all gone. Hit the West Michigan bubble?

My wife just called and said that in the East Paris and Cascade area the roads were flooded. She is now on Plainfield and it is not raining as hard there. I told her the rain is now done here at the house.

Had a garden variety thunderstorm came thru here not a whole lot of rain with it as just 0.11″ of rain has fallen so far. At the current time with light rain still falling it is 73 here in MBY.

There was just a trace of rain fall yesterday the official H/L was 83/52. Before the clouds moved in there was 86% of possible sunshine. The overnight low here in MBY was 65 the official overnight low at GRR was 63. At the current time it is cloudy and 78 here in MBY. The only chance of rain this week looks to be today and that is far from a slam dunk. For today the average H/L is 83/63 the record high for today is 99 in 1936 and the record low of 43 was set in 1945.

Today is the anniversary of the July 11 2011 derecho. A line of storms that produced lots of damage where I lived in Byron Center.

Have we had a better summer than this? Warm May, warm June, hottest day in years, tons of sunshine, and no big cold periods or rainy stretches.
