September 30, 12 PM Weather Forecast Update

Here is your latest update for now to November.

25-30% of showers (& even a few t'showers late today) will do for today with more sun this late afternoon-evening.  It will be windy with southwest winds becoming west, then west-northwest at 20-40 mph.

Highs of 63-71 are likely later today.

Lows should drop to 42-47 tonight with overall partly cloudy skies with a west-northwest wind at 9-14 mph.

With partly to mostly cloudy skies & strong west-northwest to northwest winds to 35 mph tomorrow, 40-45% coverage of showers & a t'showers will occur.  A couple isolated graupal or small hail producers are possible.

Highs should reach the 58-66 range from north to south.

With partly to mostly cloudy skies tomorrow night & a couple of isolated showers, lows of 43-48 are likely.

Friday looks partly cloudy with northwest wind decreasing from 10-20 mph for the first half of the day to 6-14 mph by afternoon & 5 mph by evening.

Highs of 57-63 are likely.

Some patchy frost is likely Friday night with lows 33-39 with a few clouds to patches of cloudiness at times & winds turning to the north & becoming light.  If we can get enough cloudiness to hang on with the cold air aloft & Lake Michigan influence, then we may end up warmer with lower patchy frost risk.  We will monitor.  It could also be a situation where the northern half stays cloudy to mostly cloudy & the southeast is clear, resulting in a big temperature difference over the area from 33-43.

The coldest readings will actually occur over Montgomery, Clinton to Howard & Miami counties, well away from Lake Michigan, which will keep the northwestern areas a bit warmer.

I am forecasting around 37 for Greater Lafayette.

Saturday features increasing clouds with breezy conditions developing (south-southwest at 5-10 mph increasing to 15-23 mph) with highs 63-67.

An Alberta Clipper will dive southeastward & bring a wave of some showers Saturday night to early Sunday morning with lows of 49-54.

Then, the sun should appear, cumulus towers bubble up Sunday & a few showers & storms develop in the cold air aloft. 

An isolated small hail producer or two is possible.

With strong southwest, then west to northwest winds 20-35 mph, high of 60-69 are likely from north to south over the area (around 66 for Greater Lafayette).

We turn much warmer next week with 70s by Tuesday (weak clipper with a couple isolated showers possible then) & 80s by late next week with strong southwest winds.  We could reach well into the 80s, even push 90 in some places here by October 12-13.  If we see some thick smoke come in, it will cut the temperatures a bit.

Upper ridge will dominate our area as massive storm off Washington, Oregon & California coast (storm merging with old Pacific major hurricane), drop very deep trough well west of the area.  This could bring flooding rains & mudslides to parts of the Far West, while record heat is possible South Dakota, Nebraska to Kansas, Iowa & Colorado.  Parts of South Dakota to Kansas could be pushing 100.  Also, a hurricane will be brewing in the western Caribbean to Gulf of Mexico. 

I do not agree with the position of the hurricane in the model below.  I think it will be more toward Florida & then may ridge up the East Coast or move due north into the Appalachians.  We will monitor.

My thoughts are that there will be a landfall over northwestern Florida around October 12, but the National Hurricane Center will have official forecasts out with time & we will be posting those.

We look very warm in this period until around October 15-16 when a strong cold front passes.  Some showers/storms are possible. 

Deep analog analysis with focus on early traditional La Nina (currently now nearing -1.0) Falls with & more neutral MJO with negative PDO & PNA shows better potential of some severe weather with this front from Kansas to Minnesota (SLIGHT RISK possible).  We look to get the leftover currently with perhaps a broken line of some showers & storm, however.  We will monitor.
