Ring of fog/low clouds is lingering in our northeastern counties after fog & some areas of low clouds this morning.

Lake Erie was a big influence this morning & now to midday as fog/cloud deck drifting east & southeastward from the lake blanketed eastern Michigant to northwestern Ohio to northern Indiana this morning.

This will gradually mix out with the heating of the day.

Another fog & low cloud deck is mixing out over eastern Iowa & northern Illinois.

Given the variablity in the clouds over the area between this deck & the sun elsewhere, temperatures vary from 69 in the northeast to as high as 83 elsewhere.

Some patchy fog & patchy low clouds are again possible tonight with lows near 60 to the 60s.

Cloudiness & fog should erode with time tomorrow morning, followed by a period of partly cloudy skies of cumulus before turning mostly sunny by late afternoon-evening.

Highs of 83-89 are likely with heat indices of 86-92 with a southeast wind.

Thursday looks dry with some morning patchy fog with 60s, followed by 85-91 with heat indices of 88-97.

Friday will feature partly cloudy skies after some patchy fog in the morning.  A couple/few isolated storms are possible in the afternoon-evening with highs 88-92 (heat indices 90-99) after morning lows in the 60s.

As for Saturday, it looks partly cloudy with highs 84-90 with heat indices 89-97.  A few scattered storms are possible in the p.m., mainly in the western counties.

The moisture plume coming up from the south you see below is what brings our potential of a couple/few isolated storms Friday.

Remnants of a Pacific hurricane & Texas tropical depression will combine with a cold front to bring widespread rainfall Sunday.

A few storms are possible at the onset, then steady rainfall, heavy at times.

Given the tropical nature of the rainfall, it is possible for 1-2.50" to fall over a good chunk of the area.

It would all fall between Sunday 4 a.m. & 5 p.m.

Highs will only run in the 70s after a morning low near 70.

Monday looks dry & partly cloudy with 70s.

Some rainfall is possible Tuesday as another cold front arrives.  It does not look as widespread or as substantial as Sunday, but it will be around with highs in the 70 to 70s range.

Some showers are possible Thursday night, Friday to early Saturday with highs in the 70s cooling to 60s by the next weekend.

September 28-October 2 features quite cool weather, especially in the mornings with lows in the 30s to 40s.

End of September to first few days of October:

Note the strong Canadian high over Virgina on the morning of October 3 & the strong southwest winds returning.

This signals & quick, very pronounced warm-up.

Also note the potential hurricane making a Mexico or Baja California landfall.

There is also considerable disturbed weather in the southern & southeastern Gulf to far southwest Caribbean. 

This could become a tropical system.

This all spells the POTENTIAL of a period of substantial rainfall for us with much warmer, more humid weather October 6-8.

Cooler weather should follow.

Mid-October is still trending warmer than normal overall.

It looks drier than normal as well.

Looks like a cool-down with some cold mornings, then warmer weather & wetter, stormy weather as we approach Halloween & move into early November.
