SPC AC 160718
Day 3 Convective Outlook
NWS Storm Prediction Center Norman OK
0118 AM CST Fri Nov 16 2018
Valid 181200Z - 191200Z
...NO SEVERE THUNDERSTORM AREAS FORECAST...
Severe thunderstorms are not expected on Sunday.
A low-amplitude shortwave trough may move through the mid MS and OH
Valleys during the period but the upper pattern, characterized by
western CONUS ridging/eastern CONUS troughing, will likely remain
relatively unchanged throughout the period. Surface pattern will be
dominated by high pressure associated with a continental polar air
mass, although a low may move through the northern Plains Sunday
evening/early Monday morning.
Stable conditions associated with this cold air mass will temper
thunderstorm chances throughout the majority of the CONUS. The only
exception is across south TX where enough low-level moisture will be
in place ahead of the southward-progressing cold front to support
isolated thunderstorm development. Limited instability should
preclude any severe storm threat.
