Summer 2021 was the 16th warmest on record, after the 11th warmest in 2020.
We saw our first 100 in the viewing area since 2012. 100 was reached at the Purdue Ag Farm & the Purdue Airport in June with multiple locations in the viewing area reaching 98-99.
June 25-July 5th's 6-12" of rainfall was critical to crop development that was early due to the very warm spring & early Summer. Corn was tasseling in many areas by July 4. This rain was extremely important in being the difference between Moderate D1 & Severe Drought D2 & just Abnormally Dry D0 to Moderate Drought D1 conditions.
Ida remnants continue to produce major flooding in Pennsylvania with Flash Flood Emergencies with life-threatening flash flooding over a corridor from near Philadelphia to Bridgeport. Incredible rainfall rates are occurring atop wet soils from previous tropical rainfall.
Many rescues are underway with evacuations in the pink shading below. Many, many roads are flooded with some interstates closing. Building collapse from heavy rain has injured 7 people in New Jersey. Mudslides & road collapses area occurring in eastern & southern Pennsylvania.
The National Guard has been called out in Pennsylvania, while multiple cities have declared a State of Emergency, including New York City.
Damaging flooding from Ida has already occurred from southeastern Ohio & West Virginia to Virgina & Maryland.
Meanwhile, Nora remnants are bringing welcome, but flooding rainfall from Colorado & Utah to New Mexico & Arizona. Flash Flood Warnings are up for the Phoenix area & Flood Advisories are up over northeastern Arizona.
Highs yesterday reached 78-83 with low dew points in the 40s & 50s with northeast winds 15-30 mph.
Wind will continue to diminish tonight to 2-5 mph from the northeast. Some patchy fog is possible over Newton, Jasper to Benton counties. Lows will run 51-56.
With lots of sunshine, highs will reach 77-82 with low humidity tomorrow & east-northeast winds 10-20 mph Thursday. The humidity will still be low with dew points in the 40s & 50s.
After 53-57 with increasing high clouds Thursday night, highs should reach 79-83 Friday with wind going light & to the southeast & south-southeast. Sun will be filtered by high & mid clouds with partly cloudy skies Friday with continued low humidity (dew points in the 50s to 60).
It will turn more humid Saturday with dew points rising to 63-68 with highs 77-83 with sun/clouds with a couple to few isolated showers in the morning, then a break, followed by scattered showers & a few storms (40%) in the afternoon to early evening.
Winds will be south-southwest at 15-25 mph.
The heaviest rainfall is setting up from Missouri to southern Illinois & southwestern Indiana as some moisture from the remnants of what was once Hurricane Nora in the Pacific is squeezed out ahead of a surface cold front. 1.5-3.5" of rainfall is possible there with heavy storms & isolated severe risk.
The scattered rainfall should exit in the evening.
Sunday looks partly cloudy with an isolated shower & 80-85 with dew points dropping to 58-64 with west-northwest wind 10-20 mph. This, after morning lows of 62-66.
Labor Day itself look partly cloudy with highs 83-88 with dew points 62-66 & southwest wind 5-10 mph.
As for Tuesday, we look partly cloudy with highs 84-89 with dew points 65-70 with southwest winds 15-30 mph.
Surface cold front passes Tuesday PM with some scattered storms. Coverage of storms may not be great (up to 35%), but strong wind fields & overall shear support some severe risk from wind/hail. SLIGHT RISK parameters show up from Missouri & Iowa to Illinois to part of our area.
Key area to watch late September to October is any part of Florida & along parts of the East Coast for tropical storms & hurricanes.
It looks unusually warm with record warmth possible at night within the September 10-15. Record highs for that stretch are 96-100, but record high low temperatures are 72-74 in the 1879-2020 period during that time. So, our 90-95 highs may approach a few record highs, but will likely not exceed them, but the overnight lows may break warm weather records.
After some storms around September 15-16 (with preliminary parameters suggesting SLIGHT RISK, though storm coverage does not look to exceed 40% at this point with wind/hail risk), we look to see the first real taste of Fall with chilly nights of 42-47.
Still plenty of warmth shows up after that to early October.
Overall trend continues to be below normal rainfall.
