URGENT - IMMEDIATE BROADCAST REQUESTED
Tornado Watch Number 104

305 PM EDT Thu Mar 30 2017

The NWS Storm Prediction Center has issued a

  Central and southern Indiana
  Western Ohio

  1000 PM EDT.

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

SUMMARY...The air mass will continue to gradually destabilize along
and south of a northward-moving warm front across Indiana and
western Ohio. Aside from a damaging wind/some hail risk, moderately
strong low-level shear will support the possibility of tornadoes,
particularly near the warm front.

The tornado watch area is approximately along and 55 statute miles
north and south of a line from 10 miles west northwest of Terre
Haute IN to 35 miles north of Dayton OH. For a complete depiction of
the watch see the associated watch outline update (WOUS64 KWNS
WOU4).

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 103...

surface and aloft to 2 inches. Extreme turbulence and surface wind

  Central and southern Illinois
  Western Kentucky
  Far eastern Missouri

  until 800 PM CDT.

* Primary threats include...
  Scattered damaging wind gusts to 70 mph possible

  A tornado or two possible

SUMMARY...Strong to severe thunderstorms will continue to develop
and intensify as they race northeastward from far eastern Missouri
into central/southern Illinois and western Kentucky. A marginally
moist and unstable environment and ample vertical shear will support
a wind damage risk along with some potential for hail and possibly a
brief tornado or two (mainly across Illinois portions of the Watch).

The severe thunderstorm watch area is approximately along and 60
statute miles east and west of a line from 30 miles north northwest
of Decatur IL to 35 miles south of Paducah KY. For a complete
depiction of the watch see the associated watch outline update
(WOUS64 KWNS WOU3).

PRECAUTIONARY/PREPAREDNESS ACTIONS...

REMEMBER...A Severe Thunderstorm Watch means conditions are
favorable for 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. Severe thunderstorms can and occasionally do produce
tornadoes.

AVIATION...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 450. Mean storm motion vector
