The heat has been impressive in the Great Lakes & Southeast Canada area over the past 24 hours with many record highs.
California is starting to see near record heat now. That is some of the heat that will bring us a potential early-season heat wave next week.
Highs today reached 84-90 with heat indices as high as 96.
This marks the third consecutive day at 90-91 for some observation sites, including Logansport-Cass County Airport & 6 NE Winamac.
A wave of scattered showers & t'showers is possible late tonight-Wednesday morning, then a break with sun, followed by scattered storms developing in the afternoon.
Highs will run in the muggy 82-89 range. Heat indices should peak at 88-95.
Also, potential is there for a tropical storm to develop & make landfall in South Carolina Wednesday or Thursday before its remnants race northward to Pennsylvania.
The National Hurricane Center has a 30% chance of the low to develop into a tropical system over the next day or two.
A wave of some showers & storms are possible Thursday morning, followed by a break with some sun, then scattered storms bubbling up.
Cold front should pass Friday morning-midday with scattered showers & storms.
Less humid air with some clearing should work in after 2 p.m. Friday with a nice, refreshing northwest wind 15-30 mph.
Next weekend looks great with highs 71-77 & lows 45-52! Cumulus clouds will pop both Saturday & Sunday, but they will be fair-weather cumulus mediocris & not the big congestus towers that grow into cumulonimbi or showers & storms.
Humidity looks much lower next weekend.
However, record-breaking heat wave will develop in the West with time this week & then expand & move eastward.
Warm front should pass Monday with potential of a few isolated storms, then heat will overspread the area Tuesday & especially Wednesday.
Heat wave is possible Wednesday to Sunday of next week (June 3-7) with 90s.
It looks rather dry, however, if the ridge contracts any amount, it could bring a "Ridge Rider" or bring severe storm complex(es) in the "Ring of Fire" to part of the area. We shall see.
1 p.m. temperatures Wednesday are forecast to be 88-91. Note the 90-95 temperatures Minnesota to Texas.
Highs of 90-95 are possible. Heat indices of 92-100 are possible.
At 1 p.m. on Thursday, temperatures are 90-95 over the viewing area.
Highs of 92-97 are possible Thursday-Friday. Heat indices of 97-103 are likely.
Temperatures at 7 a.m. Friday morning are forecast to be very warm at 75-81 with south-southwest wind at 15-25 mph.
The temperature anomalies in early June are notable:
Rainfall anomalies in early June look below normal over much of the eastern U.S. under the hot ridging.
Flooding rains & severe weather outbreaks are possible Montana to Ontario.
Here, trend now is for normal or slightly-below normal rainfall for early June.
Above normal temperatures dominate mid to late June with below normal temperatures in the West & over wetter soils in southern Texas.
Rainfall in mid to late June is trending normal to slightly above normal here.
July continues to trend above normal with below normal temperatures in the Far West & Texas (wetter soils from heavy rainfall).
Rainfall looks a bit below normal in July with lots of heavy rainfall in the South due to largely active tropics.
