Heat Continues for a Couple Spots this Weekend

28 Aug 2021, 2:50 pm

Sweltering heat has hit the central and southern Mississippi Valley the last few days as a strong ridge of high pressure sits over the middle of the nation.

Central US

Heat alerts continue today for the central United States as temperatures will feel like the triple digits for areas around the Mid-Mississippi River Valley.

High temperatures in the Plains will be well into the 90s, but with high humidity and dew points in the 70s, the heat index will be above the century point.

Some relief arrives late this weekend and into next week behind a cold front. Temperatures and humidity will decrease and places like St. Louis will have near-average temperatures through the end of the work week.


More heat is ahead for the Desert Southwest through the weekend into Monday as a ridge of high pressure sits over the area. This will also inhibit monsoonal moisture across the Four Corners region.  The heat could be dangerous for cities like Yuma and Las Vegas. Temperatures region wide will stay above average with many spots 5-10° warmer than normal.

Highs this afternoon kick off the stretch of the intense heat into the weekend.

Heat will start to break by Tuesday for many locations but it will still be hot.

Northern California will also be hot, with heat alerts continuing for the Ukiah area through Sunday.

High temperatures will be near 100 for most of northern California. Northern Nevada will be cooler, in the upper 80s and low 90s.

Temperatures will begin to tumble by Tuesday here as well, falling back to near average by mid-week.

As always with extreme heat check on elderly or ill neighbors, never leave children or pets unattended in a vehicle, avoid strenuous work during the heat of the day, take frequent breaks and stay hydrated!
