UPDATE: Mississippi wraps up hottest week of the summer breaking or tying 80+ records
A persistent heat wave over the Southern Plains is set to expand and intensify across Mississippi over the next several days with more triple-digit temperatures likely.
High temperatures across parts of Texas and Oklahoma have been topping the 100 degree mark for much of the month of July including in Dallas, where they have experienced 29 straight days of triple-digit heat, which is tied for the second longest consecutive streaks on record in that city.
This heat associated with a upper ridge of high pressure is expected to expand across Mississippi and combine with high humidity levels to produce daily dangerous heat indices over 105 and in excess of 110 and possibly 115 degrees in some areas through much of the upcoming week.
Actual high temperatures by Wednesday will be averaging in the upper 90s to around 100 degrees statewide with low temperatures in the mid and upper 70s to around 80 degrees.
It has already been a very hot summer season across Mississippi with many locations recording multiple 100 degree days.
The capital city of Jackson has hit the 100 degree mark 11 days this summer so far and could possibly experience at least two more during this week’s oppressive heat.
This will occur with only a slim chance of an afternoon and evening shower or thunderstorm to cool things off with the best chances confined to Southern Mississippi.
LIVE MISSISSIPPI WEATHER/CAMERAS
The National Weather Service has already issued Heat Advisories and Excessive Heat Warnings across much of Mississippi including 77 out of 82 counties, extending through at least Tuesday.
These advisories and warnings will likely be extended through the week as this intense heat wave unfolds.
Heat-related illnesses become more likely with prolonged exposure to very hot and humid conditions, which is expected.
At least five people have died from the intense heat and humidity experienced in the state so far this year.
Everyone is strongly advised to use extreme caution when spending any prolonged length of time outdoors.
The end of July and the first half of August is typically the hottest stretch of the summer season across our region.
