URGENT - IMMEDIATE BROADCAST REQUESTED
Tornado Watch Number 55
NWS Storm Prediction Center Norman OK
710 PM CDT Sat Apr 13 2019

The NWS Storm Prediction Center has issued a

* Tornado Watch for portions of 
  Northern and central Alabama
  Eastern Mississippi

* Effective this Saturday night and Sunday morning from 710 PM
  until 300 AM CDT.

* Primary threats include...
  A few tornadoes likely with a couple intense tornadoes possible
  Scattered damaging wind gusts to 70 mph likely
  Isolated very large hail events to 2 inches in diameter possible

SUMMARY...Severe storms are expected to develop and potentially
increase through late evening across eastern Mississippi into
northern/central portions of Alabama, with the most intense storms
favoring a sub-regional area near a warm front where low-level shear
is maximized. This will include the potential for a few
semi-discrete supercells, although a mixed convective mode is most
likely. Tornadoes will be possible, a couple of which could be
strong, aside from damaging winds and possibly hail.

The tornado watch area is approximately along and 70 statute miles
north and south of a line from 55 miles northwest of Meridian MS to
20 miles northeast of Birmingham AL. 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 54...

AVIATION...Tornadoes and a few severe thunderstorms with hail
surface and aloft to 2 inches. Extreme turbulence and surface wind
gusts to 60 knots. A few cumulonimbi with maximum tops to 550. Mean
storm motion vector 22035.
