Highs today ran 64-74 after morning lows of 46-51.

It was also the windiest day we have seen (non-t'storm winds) since June with peak gusts at 31-43 mph over the viewing area.

Lows of 42-47 are likely tonight with skies becoming partly cloudy.

Thursday will be windy (gusts +30 mph from the west to northwest) with isolated showers in the morning giving way to a scattering of some showers & t'showers in the PM.  A couple showers, t'showers may produce graupal or small hail.

Highs of 58-67 north to south area expected with around 63 in the Greater Lafayette area.

Friday looks partly cloudy after 40-45 in the morning & highs 57-63.

Some patchy frost is likely Friday night-early Saturday morning with lows 33-39 (37 around Greater Lafayette).  It appears that the coldest temperatures will set up over our eastern & southeastern counties.

The relatively warm waters of Lake Michigan & some scattered clouds/cloudiness will prevent the temperature from getting as cold in the northwest.

Clouds will increase Saturday with highs 63-67 with breezy conditions (south-southwest wind 15-24 mph).

The clipper system will bring one wave of showers Saturday night to early Sunday morning with lows 48-54.

Then, some sun should appear & clouds bubble up with some scattered showers & storms possible (isolated small hail possible). 

Highs will run 60-69 with strong southwest to west to northwest with gusts +30 mph.

A clipper with gusty southwest, then west winds & a couple isolated showers is still on-track for Tuesday PM with highs of 67-73.

Winds should diminish & skies turn mostly sunny to sunny skies Wednesday with highs 66-74, followed by lows of 39-46 Wednesday night.

On the back side of the surface high, the winds should go southwest & increase Thursday with mostly sunny to sunny skies & highs 73-79.

Meanwhile, hurricane will likely make landfall on the Panhandle of Florida or right into Apalachee Bay.

You can see the soil moisture anomalies from across the Northeast through the Corn Belt (except northwest Illinois & southern Wisconsin) back to western Nebraska, Colorado & over the Four Corners (as compared to normal for the time of year).

It is especially dry from eastern & northeastern White to Pulaski, Fulton, northern Miami, Cass & northern Carroll counties.  Some spots have are now in a 7" deficit for rainfall since June 1.

You can see areas from Lake Freeman & Shafer, through the Tippecanoe River Valley, northeastward to the Fort Wayne area that are especially dry with some areas only seeing 50% of their normal rainfall for the past 180 days.

Many lakes, rivers & streams are very low in the area, especially from White to Fulton counties & northeastward.  Evaporation was also above normal this summer, especially in late May, through June & into July.  June 6-20 saw the highest evaporation rates in the growing season since 2012 with temperatures as high as 95 in the area & 12 of those days with the relative humidity over much of the area as low as 12% with dew points to the 30s & 40s.  Such low dew points in June are rare & prior to 2020, you have to go back to 2012 to find that kind of dry air in such a lush, green, wet time of year.  Prior to that, you have to go back to 1992, then 1988 to find dew points & evaporation like that.

To have so many days in a row with that kind of evaporation in June usually only occurs once or twice a decade (average out to 1.8 actually over the past 70 years).

In terms of rainfall, it looks below normal for the month of October.

Temperatures look above normal for October.

Usually in the early stages of a La Nina, you'd see the warmth farther east & below normal temperatures developing in far western Canada to the Pacific Northwest.  Not in this case, however.

For November...........

Above normal precipitation should occur from the Pacific Northwest to the Northern Rockies eastward through the northern Plains to the northern Great Lakes & Northern New England.  Our precipitation looks a bit below normal.

Below normal temperatures & above normal snowfall should dominate from the Pacific Northwest through the Northern Rockies, Northern Plains, Northern Great Lakes, but below normal in New England.

Above normal temperatures & below normal snowfall should occur for the rest of the Lower 48.

We look overall warmer than normal.
