A Flash Flood Watch has been issued for our area through Sunday evening due to the heavy rains we are set to receive this weekend. Additionally a Tornado Watch has been issued for counties to our north and west. The watch currently does not include Collin or Denton counties, but considering the anticipated weather set for tonight, we very well may have this watch extended to our area, or a new one issued later today. Again, this event is set to be a very large hail and high wind event. I will provide updates to this, but plan accordingly! Both watch details are below.

ONCE INHIBITION IS OVERCOME. CELLS SHOULD QUICKLY ACQUIRE SUPERCELL
CHARACTERISTICS WITH JUST ENOUGH DEEP-LAYER SHEAR TO SUPPORT
PERSISTENT UPDRAFT ROTATION. VERY LARGE HAIL SHOULD BE ONE OF THE
MORE SIGNIFICANT THREATS WITH THIS DEVELOPMENT GIVEN MAGNITUDE OF
CAPE AND STRENGTH OF UPDRAFTS. TORNADO POTENTIAL WILL BE MODULATED
BY OVERALL STORM EVOLUTION. HOWEVER…CELLS TRACKING NEAR THE FRONT
AND OUTFLOW WILL HAVE ENHANCED LOW LEVEL SHEAR/VORTICITY AVAILABLE
TO THEM AND COULD END UP PRODUCING A COUPLE OF TORNADOES.
