Summer Heat Returns For Labor Day

heat advis

Summer heat is set to crash the Labor Day party with highs soaring over 100 for most of the area. A Heat Advisory has been issued for much of eastern Oklahoma and parts of the River Valley through Tuesday evening.

In the wake of Isaac a strong, summer-like, area of high pressure will continue to build into the area leaving the unofficial start of fall feeling more like the sweltering days of summer. 

This high-resolution model (NAM4) takes temps on Labor day to near 100 across most of northwest Arkansas and much of the River Valley. This, combined with some humidity will push heat index values near or over 105. Portions of southeast Oklahoma that missed much of the rain from Isaac will see highs on Labor Day near 105.

This ridge of summer heat will start to weaken by Wednesday as a weak cold front tracks across the area; however, by late in the week a stronger cold front with plenty of energy will sweep through bring an end to the summer heat and ushering in more fall-like temperatures.

Shower and storm chances will increase along the front Friday into Saturday. Highs behind this front will drop into the upper 70’s and low 80’s by Sunday.
