Highs Friday reached 87-93, Saturday 87-95 & Sunday 83-93 (more clouds around). However, Sunday saw the highest heat indices , despite the bit cooler actual air temperatures due to much higher dew points. They peaked at 87-92 Friday & 86-94 Saturday (yes, the air was so dry, it felt cooler than the actual air temperature) & Sunday 85-96.
The hottest temperature was at Morocco with 93. That was the southern edge of the much hotter weather of the upper ridge.
It was 93 at the Alpena Airport (northeast Lower Michigan), 88 on Drummond Island Airport southeast of Sault Ste. Marie (completely surround by COLD, COLD water), 93 at Houghton, Michigan on Lake Superior at the tip of the UP & 93 at Petawawa, Ontario (2 hours northwest of Ottawa). At Kapuskasing, Ontario, the high was 91 (central Ontario).
Franklin County Airport hit 94 on the border of Vermont & Quebec, Whitefield Mountain Observing Station in northern New Hampshire reached 90, 95 Burlington, Vermont, Fryeburg, Maine hit 95, while coastal Massachusetts soared to 95. Teterboro, New Jersey at 99 was accompanied by 99 at Westminster, Maryland & Buckhannon, West Virginia Airport was 95, Georgtown, Delaware 95 & 97 at Newark, New Jersey.
Meanwhile record low daily highs occurred in Mississippi to Alabama & Tennessee with just 73 at Columbus, Mississippi, 75 Tupelo, Mississippi, 73 Meridian & Brookhaven, 76 Memphis, Tennessee, 73 Dickson, Tennessee & 72 at Lexington. Cullman, Alabama was just 72, while 73 Decatur, Alabama. Parts of the Florida Peninsula was near record hot with around 100.
Hot ridge is dominant over the northern U.S. for much of June, including its presence here frequently.
It is trending drier than normal with rapidly-worsening drought underneath that ridge in the West, Plains & parts of the Corn Belt to Michigan & Ontario. We are close to the really worsening drought & close to the wetter weather south of the area, but we favor drier.
Nonetheless, we will thankfully have opportunities for scattered storms all week to next weekend & again around June 20.
Early July looks hotter than normal with upper ridge showing domination in the northern to Midwest & northeastern U.S.
We look overall drier than normal, but the South will continue to be unusually wet.
There will be opportunities for tropical development June-July in the Gulf & Caribbean.
Those systems will be monitored for a sneak into our area with welcome rainfall.
Otherwise we are looking at scattered storms (peak coverage tending to be in the afternoon-evening) daily Monday-Sunday with daily highs in the 80s & muggy dew points near 70 to the 70s.
Rainfall will be highly-variable & hit-or-miss. Some of you will see heavy downpours, others will keep missing a lot of them.
If there is a severe storm, it would be isolated with sudden, brief wet downburst from storm pulsing up & collapsing. The main mid & upper level winds for organized severe weather will be way, way up in Canada.
If not for the upper low & the deep tropical moisture in the South & Gulf moving northward, much of the U.S. would be very hot & dry like 2012 now & into July (given how expansive the hot upper ridge is from Canada to the northern U.S.).
So..........Monday: scattered showers with cloudy to mostly cloudy skies, then sunshine in the afternoon with scattered storms bubbling up in the heating (south to south-southwest winds 12-25 mph). Highs of 82-88 are expected with mugginess.
As for Tuesday: couple Am showers, then scattered storms bubble up again with south to south-southwest winds 12-25 mph. The mugginess will continue with 82-88.
Some showers are expected Wednesday morning, but then sun should appear with clouds bubbling up in the afternoon with scattered storms. Again, mugginess continues with 83-88 with south to south-southeast wind 15-28 mph.
After the end of next weekend, we look dry & increasingly hot as upper ridge re-expands until potential tropical remnants &/or cold front pass near June 20. That will bring brief rainfall & comfortable relief before we really heat back up.
