Strong to Severe Storms Possible Wednesday Afternoon and Evening northeast of San Antonio

Area of Concern:

Impacts:

Damaging straight-line winds and/or large hail with any severe storms

Dangerous cloud to ground lightning

Local pockets of heavy rainfall across Lee, Bastrop, and Fayette counties

Timing and Overview:

A  cold front will interact with an upper level disturbance to produce  scattered thunderstorms across portions of South Central Texas late  Wednesday afternoon and evening, during Halloween activities for some.  The greatest chances for storms will be near and east of an Austin to  Bastrop to Halletsville line. The Storm Prediction Center has raised the  chance for severe storms near and east of this line from Slight to  Enhanced. A few of these storms will be capable of producing damaging  winds and large hail. Lesser  chances for storms exist to the southwest, toward San Antonio, however  if storms do form in this area they will also be capable of becoming  strong to severe. 


Also,  those with outdoor Halloween activities late Thursday afternoon through  the evening should remain weather aware not only for severe storms but  the threat for cloud to ground lightning. If you are close enough to  hear thunder you are at risk from being struck by lightning.


The  system should move quick enough to preclude significant flooding.  However a few pockets of heavier rainfall of 1-3" are possible across  Lee, Bastrop, and Fayette counties could occur, resulting in spotty,  minor flooding.


Forecast  confidence remains low to moderate on timing and location. Stay tuned  over the coming day as details become refined on timing, location, and  threats/impacts.
