May Summary

We have a cool 53° at 6:30 this morning with some light rain around the area.  Yesterday’s high was 75° and the low 54°.

Expect showers to move out this morning then sunny skies this afternoon and on Friday, with winds that will gust up to 30 mph on Friday. Our best chance of rain is Saturday night into early Sunday.


The month of May could be characterized by the warmer than normal temperatures felt across the region. Precipitation amounts varied with much lower than normal values at Muskegon compared to the well above normal values at Lansing.


Forecast Discussion

As a closed upper low over Manitoba ejects a vorticity offshoot, its
associated shortwave trough will move east through the area early
this morning. Mid and high level clouds will enhance with scattered
light rain possible until the mid to late morning hours. Bufkit
profiles continue to signal a drier low level below an altostratus
layer, so there is a good chance that most areas could stay dry with
primarily virga occuring.

Behind this midlevel wave, high pressure will build in from the
west and skies will become mostly sunny apart from typical diurnal
cumulus development through Friday night. Despite the abundant
sunshine, temperatures will stay a touch cooler than normal with
highs barely tapping into the low 70s. Similar conditons can be
expected for Friday although a deeper mixed layer will develop
that may reach into some stronger winds aloft. Wind gusts up to 25
to 30 mph will be possible Friday afternoon.

Zonal flow will support this quiet pattern for the next couple of
days before our next chance for rain arrives late Saturday and
Sunday. A few chances of rain will continue through early next
week as additional waves move through. Meanwhile cooler-than-
normal temperatures will be favored into next week with highs
ranging from the upper 60s to low 70s.

Made it to the mid 70s this afternoon at my house. Overall a pretty nice day. A touch warmer than the forecast 73 for my house so that was nice as well. Time to go get some Tacos for dinner and maybe a walk as well. Everyone enjoy your evening!

The CFSv2 continues to show below average temperatures for June. The latest long range guess has 3 of 4 weeks below average with a up and down pattern for rain fall.

Most summer forecasts I’ve seen say a cooler/average June after a warm May – then a hot July and August.

Yesterday was GR’s 5th warm day out of the last 7. Five days prior to that, GR saw 10 warm days out of 12. We’ve really enjoyed some early summer warmth this year!

As Make indicated we are now in a “don’t have to” pattern that is don’t have to have the heat on and don’t have to have the AC on. I think that the heating cost will be going up a lot in the winters ahead. Even now the heating cost here in the north are much higher than the cooling cost. Some may not believe it but you can live in Michigan without AC (it makes in more conformable but one can live without it) it is hard to live in Michigan without some kind of heat in the winter… Read more »

I’ll second that, Mark. I would be fine with the whole month staying around 75-80 degrees. It makes working outside much for tolerable…

Slim

It would be great if highs could be around 75 to 80 all year long. But then we would not be living in Michigan anymore.

It’s so nice to be able to open the windows again. With gasoline nearly $5, we’re trying to save in other areas – like using the A/C.

Slim

It also would be nice if we could keep the heat off in the winter time but that is yet another story.
