A Tornado WATCH is in effect until 5pm for portions of southeast Texas.  This includes the counties of Chambers, Liberty, San Jacinto, Polk, and Trinity counties and includes the Galveston Bay area.  Cities within the WATCH area are Anahuac, Cleveland, Coldspring, Corrigan, Dayton, Groveton, Liberty, Livingston, Mont Belvieu, Onalaska, Shephert, Trinity and Winnie.   The immediate Houston area is NOT included in this WATCH.  Severe storms will continue to develop this morning as a warm front retreats off to the north/northeast, with a lull in storm activity possible by early afternoon as the initial batch of storms moves east and into Louisiana.  A second round of storms is likely this afternoon in advance of a strong cold front expected to move through southeast Texas later this evening. Large hail, damaging winds and a few tornadoes will be possible with these two rounds of storms today.  Very heavy rainfall and localized flooding issues will also be present mainly for areas east and northeast of the Houston metro area. Folks within the WATCH area will need to keep an eye on conditions today and monitor local media for the latest on storms in their immediate area.

 

Tornado Watch Number 190
   NWS Storm Prediction Center Norman OK
   730 AM CDT Wed May 3 2017

   The NWS Storm Prediction Center has issued a

   * Tornado Watch for portions of
     Southern and Western Louisiana
     Southeast Texas
     Coastal Waters

   * Effective this Wednesday morning and afternoon from 730 AM
     until 500 PM CDT.

   * Primary threats include...
     A few tornadoes possible
     Scattered large hail and isolated very large hail events to 2.5
       inches in diameter possible
     Scattered damaging wind gusts to 70 mph possible

   SUMMARY...Severe thunderstorms will continue to develop and spread
   east-northeastward today. Strengthening low-level/deep-layer shear
   and an increasingly moist air mass near an inland-developing warm
   front will support supercells capable of large hail and a few
   tornadoes. Over time, one or more clusters may evolve and move
   eastward with a damaging wind risk especially across southern
   Louisiana.

   The tornado watch area is approximately along and 70 statute miles
   north and south of a line from 40 miles south southwest of Lufkin TX
   to 50 miles south southeast of Baton Rouge LA.
