Thursday's peak heat index of 99 at WLFI was the highest since 105 on July 21.
Thursday's 92.8-degree high here at WLFI was also the highest since 94.1 on July 20.
The official record actual high temperature for the date (not the heat index) at West Lafayette is 97 set in 1897 during a significant drought.
The Purdue Airport hit 92 with a peak heat index of 97.
The highest temperatures of the observation sites include 94 at the Covington INDOT site with peak heat index of 101. The Danville-Vermilion County (IL) Airport hit 94 with a peak heat index of 101, as well.
The highest heat index at area observation sites was 106 at the Morocco & Fowler.
Readings on a couple properly-sited weather stations in Benton County hit 95.
Note the pocket of the lowest rainfall in the entire viewing area of the past 30 days in that area, likely leading to the localized higher readings there
Some scattered storms occurred in the north half of the viewing area yesterday afternoon-evening. One report of severe weather was received: a measured gust of 66 mph approximately 5 west of Rochester on the Gohn Farm at 4:15 p.m.
Small, brief wind cores were seen northeast of Logansport & east of Mexico that support gust potentially 58-65 mph, but no reports were received. The closest weather station to any of those areas was the Peru Municipal Airport with a measured gust of 30 mph southwest of one of the wind cores.
The east of Mexico storm also showed high probability of 0.75-1" hail, but I did not receive any reports. The closest hail report was 1" hail in Kosciusko County, 3 miles south-southwest of Nappanee.
Line of storms with some severe weather continues to congeal to our northwest & west with Severe T'Storm Watch up until 2 a.m. this morning.
We look to only get a few spotty/scattered showers/isolated storms from the leftovers this morning.
Then, a few new storms will pop on the actual cold fron in our far east midday-early afternoon.
After a very warm to hot, muggy morning to midday, a gradual decrease in the humidity will occur from dew points of 70-75 up to midday, falling to 60-65 by evening, then 50s overnight.
Highs today will run at 82-88 with peak heat indices 86-95.
There is the risk of an isolated severe storm where spotty storms form on the cold front in our eastern counties.
82-86, sunshine, some clouds & low humidity will occur Saturday with a light wind (after patchy fog & 55-59 in the morning).
Humidity will surge Sunday & after 60s in the morning, highs of 85-90 are likely with heat indices 90-96.
A few isolated storms are possible with warm front surging back northward.
It looks hot & humid Monday through Friday of next week with just a few isolated storms Tuesday-Friday.
Daily highs of 87-93 are likely with daily heat indices of 94-101. Overnight lows of 67-72 are expected.
Heat everywhere next week with above to well-above normal temperatures for the central, northern & eastern U.S.!
Only California to Montana look much cooler than normal.
Meanwhile, a tropical system should make landfall in Florida or nearby & meander through the Southeast & Appalachians.
Given its slow movement, flooding will be a concern.
NHC thinks it will make a Florida landfall as a tropical storm late Saturday & then move back out to coastal South Carolina by late Tuesday. There, it may re-strengthen & it is really anyone's guess what happens after that with a lack of good steering.
Explosive development should be hampered by the upwelling of cooler water from previous Hurricane Dorian. Explosive development would tend to occur with the un-upwelled very warm water away from the coastal Carolinas.
I have been going with the thread of meandering & stalling over the Southeast over land, but the new idea of re-emergence over the coast throws a new wrench to this tropical forecast.
No matter which way you slice it, it does not look to affect our area.
The trend is to first bring a line of storms through at some point next weekend along a strong cold front. This is a bit later than what was first projected in bringing the first front through Friday night.
The front shows up well in the forecast temperature anomalies as it approaches.
We will descend into fall weather.........but NOT immediately. It looks like a stair-step process with a series of cold fronts in the September 21-26 time frame.
By the time we get to September 28, we should see a big pool of much cooler air settle in. 30s & 40s lows are possible the end of September to the first couple of days of October.
Meanwhile, the Rockies & Pacific Northwest will bake with high fire danger & potential of dangerous Santa Ana winds.
The slowing of the upper trough & cold front will need to be monitored as a potential hurricane in the western Atlantic &/or Caribbean may have a window to get closer to land masses like the Bahamas & U.S.
