URGENT - IMMEDIATE BROADCAST REQUESTED
Tornado Watch Number 95
NWS Storm Prediction Center Norman OK
335 PM CDT Tue Mar 28 2017

The NWS Storm Prediction Center has issued a

* Tornado Watch for portions of 
  Southwest and south-central Oklahoma
  western North Texas

* Effective this Tuesday afternoon and evening from 335 PM until
  1100 PM CDT.

* Primary threats include...
  A few tornadoes and a couple intense 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...As a warm front continues to spread northward and
low-level moisture continues to increase, the potential for
tornadoes should increase in addition to increasing risks for large
hail and damaging winds across western North Texas into southwest
and eventually south-central Oklahoma. These will be initially via
semi-discrete supercells, with a more linear mode and widespread
damaging wind risk later this evening.

The tornado watch area is approximately along and 80 statute miles
east and west of a line from 30 miles north northwest of Fort Sill
OK to 35 miles west of Brownwood TX. For a complete depiction of the
watch see the associated watch outline update (WOUS64 KWNS WOU5).

PRECAUTIONARY/PREPAREDNESS ACTIONS...

REMEMBER...A Tornado Watch means conditions are favorable for
tornadoes and severe thunderstorms in and close to the watch
area. Persons in these areas should be on the lookout for
threatening weather conditions and listen for later statements
and possible warnings.

OTHER WATCH INFORMATION...CONTINUE...WW 93...WW 94...

AVIATION...Tornadoes and a few severe thunderstorms with hail
surface and aloft to 2.5 inches. Extreme turbulence and surface wind
gusts to 60 knots. A few cumulonimbi with maximum tops to 500. Mean
storm motion vector 21030.
