Severely dangerous storms are imminent!

Total risks:

  • Severe Thunderstorms in PA
  • Tornadoes and Spin-Ups in PA
  • Strong Squall Lines with 70 MPH downdrafts
  • 1/2″ hail and higher in some areas

Wednesday

  • An outbreak of severe thunderstorms is likely in the Southeast and northern Gulf Coast.
  • Numerous severe storms are expected as far north as the Ohio Valley.
  • Tornadoes, damaging winds, flooding rain and hail are all threats, particularly in the Southeast.
  • A few strong and/or long-track tornadoes are possible in the Southeast.
  • Heavy rainfall will also bring the threat of flash flooding.

Wednesday Night

  • Severe thunderstorms will continue marching east ahead of the cold front from the Ohio Valley and Appalachians to north Florida.
  • Some tornadoes are still possible, both embedded in the squall line and in discrete thunderstorms ahead of the line.
  • Otherwise, damaging straight-line winds are the main nighttime concern.
  • Localized flash flooding may become a concern, particularly in the Appalachians.

Thursday

  • Severe storms are expected ahead of a strong cold front in the mid-Atlantic states, particularly in the morning.
  • Damaging wind gusts and a few tornadoes will be possible with this activity.
  • We can’t rule out a few thunderstorms farther north, perhaps to the NYC Tri-State area in the afternoon, potentially with hail and gusty winds.
