We're officially in the last week of summer. The first day of fall, the Autumnal Equinox, is September 22, next Sunday. It's fitting that we have cold temps on the way.
Sunday's rain should be out of our hair by late afternoon or evening over the far eastern U.P. The western counties should be done with rain already. Skies will become progressively more clear as a large area of high pressure moves over Upper Michigan. Highs will be in the mid to upper 50s.
Sunday night will be cold. Frost Advisories in effect for most of the central and western counties. Lows will fall into the low to mid 30s. Most of the area along the Wisconsin line will drop to below freezing. Near the lakes it will be less cold near 40. Skies will be clear and winds will be light.
As high pressure takes over the forecast, Monday will be sunny and dry. Highs will be a few degrees warmer around 60.
Monday night's lows will not be quite as cold, mainly in the mid to upper 30s and low 40s near the lakes. Skies will be mostly clear.
Tuesday will likely see a few more clouds, but still be mostly sunny and warmer with seasonable highs in the mid 60s. Tuesday night may see some light rain.
Wednesday through Saturday have chances for rain. Thunderstorms are most likely Thursday as of Sunday.
Elsewhere, deadly and historic flooding continues in Colorado. I saw one report saying that some parts of the state have seen over 14" of rain in a week when they normally see only 2" in the whole month.
Also, Hurricane Ingrid is close to making landfall in Mexico and will also impact southern Texas from the Caribbean. On the other side, Tropical Storm Manuel has recently formed on the Pacific side of Mexico.
