NWS UPDATE: Severe Storms Possible Today/Tonight (April 9th)

From: National Weather Service, Fort Worth
Date: Friday, 9 April 2021 9:17 CDT

Bottom Line

There is a risk of severe thunderstorms especially along and to the east of the I-35/I-35W corridor today into tonight.


  • Thunderstorms are possible as early as this morning north and northeast of the DFW Metroplex. These storms could become strong or severe, capable of producing large hail.
  • Uncertainty remains high regarding the amount of thunderstorms that develop along the dryline. A strong cap will be in place for much of the afternoon. It is entirely possible that the cap holds until late this evening along the cold front.
  • The dryline will be near the I-35 corridor by mid afternoon. If the cap breaks, any storms that develop would be severe with a large hail and damaging wind threat. A tornado or two would also be possible with any supercells.
  • Instability will be high this afternoon, although wind shear may be weaker than previously forecast. This would lower the chances for baseball size hail or larger.
  • Severe weather is likely along a cold front tonight. This threat will be highest to the northeast of the Metroplex after 8 pm. Damaging winds will be the main threat, although some severe hail will also be possible.
  • We will send up supplemental weather balloons to assess the strength of the cap and actual wind shear this afternoon.

Forecaster Confidence


General Timing


What We Are Certain Of:

  • Not everyone will see severe weather or even rainfall.
  • All of the classic springtime ingredients for severe weather will be in place over the region, including a cap (that will modulate the severe weather threat).
  • If storms can develop, severe weather is likely including damaging winds and large hail.

What We Are Less Certain Of:

  • The coverage of storms. If the cap is too strong there will be fewer storms and a lower severe weather threat.
  • The tornado threat looks low, but could increase depending on the coverage and evolution of the storm system.

When will the next email update be sent?

  • This is the last email for this event.
