Highs today ran 84-90 with peak heat indices at 86-95 with partly cloudy skies & a few isolated showers/storms morning to afternoon.

A spotter 3 miles east-southeast of Earl Park measured 0.24" of rainfall in a quick downpour.

Another spotter, at Headlee (northeast White County), saw 0.02".

Moderate Drought over part of the area with only the far south & north seeing wetter conditions.

Subsoil moisture in the really dry areas helped the late-planted crop of corn & soybeans.

However, given the extra dry weather lately & the reserves running low or out, overall harvest yield is more & more likely to be the worst since 2012.

A few spotty storms are possible Saturday with partly cloudy skies, breezy, humid, very warm conditions.  Coverage will run 30%.

Band of rain & some storms will approach & pass Sunday-Sunday night.

Heaviest looks to pass Sunday late afternoon-evening with less earlier, but the band will be making headway northwest to southeast during the day.

A couple isolated severe storms are possible along & south of I-74.

1-2" of rainfall is likely area-wide by late Sunday night.

Multiple storm systems will pass Tuesday-Friday with some rainfall at times with dry time in-between with highs in the 70s after a clear, calm, potentially foggy Monday night (with lows 48-53).

Temperatures should be held down Monday-Thursday.

Warm front should shift north of our area later Friday & next weekend looks windy, very warm & humid with a few storms.  Highs of 85-90 with heat indices of 91-95 are likely.

Storms are likely Saturday-Sunday of next weekend.  Some severe weather is possible next weekend on Saturday night to Sunday with locally-heavy rainfall.

Could be two rounds of storms:  Saturday night & again Sunday PM.  Each may have some severe risk, but Sunday looks to have more.

Best potential of widespread severe with any rounds will be northwest of our area with system (Minnesota, Iowa, Wisconsin, northern Missouri, northwestern Illinois, however (it appears at the moment).

We look SLIGHT RISK-worthy in the western counties Saturday night with MARGINAL elsewhere & SLIGHT area-wide on that Sunday (based on the projected CAPE, shear, dynamics), but it is a long way out.

Wetter than normal to the end of September:

Brief summer warm spell next weekend again before much cooler spell:

Wall of cooler weather comes in as October begins.

Note the temperature anomalies projected as the cold front passes & the near-record to record heat in the Northeast & along the East Coast.

Cooler than normal weather should continue for several days.

Below normal temperature trend with drier trend in early October will transition to overall warmer than normal trend in mid-October.

Only way drier trend would change at some point in the early part of October is if we see landfalling tropical system(s) along the Gulf Coast track into area or very deep moisture plume from Pacific hurricanes returns northeastward into area.

Looks drier than normal mid-month.
