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.


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.

Areas of Concern





Threats/Hazardous Weather Types


General Timing


Forecaster Confidence


Contingency Planning

What We Are Certain Of:

  • Dangerous heat through Sunday.
  • Thunderstorm potential exists across northern portions of North Texas through the weekend, mainly during the night time hours.

What We Are Watching:

  • The position of the stalled front and the evolution of upstream thunderstorm complexes, which could determine how far south the thunderstorms may reach and where the best potential for severe weather exists.


Will there be large hail? Large hail is possible, with the better chances being either along the Red River or over the northwestern counties.
What about damaging winds? Damaging wind gusts in excess of 60 mph will be possible, with the better chances also the farther north and northwest you go.
What about tornadoes? Tornadoes are not expected.
Will there be flooding? Flooding is very unlikely, but not completely out of the question with any isolated slow-moving thunderstorms.
When will the next email update be sent? Saturday morning by 10 AM.
