DAY 2 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
1227 AM CDT SAT OCT 01 2016

VALID 021200Z - 031200Z

...NO SVR TSTM AREAS FORECAST...

...SUMMARY...
ORGANIZED SEVERE THUNDERSTORMS ARE NOT FORECAST IN THE CONTIGUOUS
UNITED STATES ON SUNDAY.

...SYNOPSIS...
A POWERFUL MID- TO UPPER-LEVEL TROUGH WILL MOVE FROM THE PACIFIC
COAST AND INTO THE INTERIOR WEST DURING THE DAY 2 PERIOD.  SURFACE
LOW PRESSURE WILL DEVELOP OVER THE NORTHERN GREAT BASIN DURING THE
DAY CONCURRENTLY AS A COLD FRONT MOVES EASTWARD ACROSS NV AND
SUBSEQUENTLY INTO UT AFTER DARK.  AS THIS OCCURS...A LEE TROUGH WILL
DEVELOP OVER THE HIGH PLAINS WHERE THE EVOLVING SURFACE CYCLONE IS
FORECAST TO DEVELOP BY DAYBREAK MONDAY.  SCANT BOUNDARY-LAYER
MOISTURE WILL TEND TO LIMIT BOTH BUOYANCY AND THUNDERSTORM COVERAGE
ACROSS THE GREAT BASIN INTO THE NORTH-CENTRAL HIGH PLAINS.  WHILE A
HIGH-BASED THUNDERSTORM WITH A STRONG GUST CANNOT BE RULED OUT OVER
PARTS OF THE NORTHERN GREAT BASIN...THE THREAT APPEARS SUFFICIENTLY
LOW TO NOT INTRODUCE PROBABILITIES.

ELSEWHERE...A MID-LEVEL LOW WILL WEAKEN OVER THE NORTHEAST STATES
WITH A LOW CHANCE FOR THUNDERSTORMS OVER THE LOWER GREAT LAKES.
ISOLATED TO WIDELY SCATTERED STORMS ARE ALSO FORECAST FOR THE FL
PENINSULA.
