NWS Update: Dangerous Heat and Storm Chances

From: National Weather Service, Fort Worth
Date: Friday, 22 June 2018 9:25 CDT

Bottom Line

Strong to severe storms are possible mostly along/north of the I-20 corridor today and this weekend. It will also be hot each afternoon with maximum heat index values at or above 105 degrees in many locations.

Overview

High temperatures will range from the upper 90s in the east to near 100-102 degrees along and west of the I-35 corridor Friday through Sunday. Heat index values will likely exceed 105 degrees for all but the easternmost counties. A Heat Advisory may be needed, though it now looks like Saturday and Sunday will be the more oppressive days.

In addition, a stalled front will create opportunities for thunderstorms along the Red River as multiple disturbances move across the Southern Plains. A few strong to severe storms containing damaging winds and large hail will be possible, especially Saturday night when thunderstorm chances are highest.
