Here’s how the next few days will shape up: The heat wave will return to record territory this weekend, with triple-digit highs across much of Texas. Temperatures will rise further as we head into the middle of the week.


A heat dome, or ridge of high pressure, will extend into parts of the Southwest and lower Mississippi Valley, as well as a little farther north in the Southern Plains. Highs will extend into the mid 90s to upper 90s to low 100s from southern Arizona into New Mexico into Louisiana, Mississippi, Arkansas, Oklahoma and Kansas.


Extreme heat can continue until early July. Significant heat relief in the southern plains is usually difficult to achieve from this point forward in summer, unless the tropical system brings heavy rainfall.

The latest long-range forecast from the National Oceanic and Atmospheric Administration (NOAA) indicates that the heat is expected to persist over the Southern Plains, from New Mexico to Texas, Louisiana, Arkansas and Oklahoma, through early July — and possibly including the Fourth of July holiday.


Long-term temperature forecast

(This forecast from the National Oceanic and Atmospheric Administration’s (NOAA) Climate Prediction Center shows the odds that average temperatures will rise higher (tan, orange, and red lines) or lower (blue lines) in the given period.)

Here’s why it’s so hot: The dome of high pressure that has persisted for much of this month over Mexico has bulged northward into the southern Plains, spreading its intense heat.

According to an analysis by Climate Central, climate change has caused record high temperatures in this heat wave in Mexico and Texas At least five times more likely.

So, take this dangerous heat seriously if you live in the Southern Plains. Avoid any prolonged and unnecessary outdoor activity, especially during the hotter times of the day. Check on seniors and anyone else who may live without air conditioning.
