Coolest weather since late May, then the return of very warm to hot, humid weather for a bit.

After highs of 75-82 Sunday, temperatures are 65-72 as of 11:20 a.m. over the viewing area as the coolest weather since mid-May moves in.  For the past 2.5 months, temperatures have overwhelmingly been above normal.  It was the hottest June-July period since 2012 & before that, 1995.  It wasn't that we had an intense +100 heat wave, but CONSISTENT heat & stretches & stretches of upper 80s & then 90s, including 5 times we were in the mid 90s officially at Greater Lafayette.  Nights were especially warm with rare occurrences of any night dropping below 60 since late May.  We also saw our official drought in the viewing area, a rare occurrence in the past several years of wet springs & summers (it being a bit of a flash drought).

Just like we saw in early August 1980, it took a hurricane to break down a pattern stuck for so many weeks.  The extreme heat wave in the southern Plains & South & our "Ring of Fire" storm pattern going back & fourth between, very hot, oppressive upper ridge broke down as Hurricane Allen hit the South.

In this case, it is Hurricane Isaias on the East Coast causing a large-scale pattern change for a bit.

ENHANCED RISK for severe weather is up for parts of the Northeast for tornadoes & Tornado Watch is up as now Tropical Storm Isaias rides up the East Coast.

Winds have gusted to 70 mph in New Jersey & New York's Kennedy Airport is measuring gusts to 52 mph.

Much of the state of Delaware is without power & massive outages extend through Maryland & southeastern Virginia.

Movement through the day to tonight:

Clouds/sun today with a couple isolated showers & brisk north to north-northeast winds will be accompanied by highs of 72-78.

Patchy fog, clear skies, light to calm winds & lows of 48-54 will occur tonight.

Highs of 77-82 are likely Wednesday with sunshine & a few clouds.

Patchy fog, clear skies & light to calm winds are likely Wednesday night with lows 50-56.

Thursday look warmer with sunshine & highs 80-85 with Thursday night lows 58-62.

We heat up & turn humid this weekend to next week with multiple rounds of storms possible in the "Ring of Fire" as hot, hot upper ridge centers over Texas & storm complexes & remnant MCVs that pop new storms pivot around it.

Cool weather with troughiness will remain in the Northeast U.S. with surface high then over western Ontario.

The gradient or the road for storms to travel will be here & near our area.

There are signs of another cool-down at some point in mid-August before we heat back up again in a big way.  Temperatures look overall above normal in late August through early September. 

Even today, it still appears a round of a bit below-normal temperatures may occur in mid-September.
