DAY 2 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
1223 PM CDT SAT OCT 02 2010
VALID 031200Z - 041200Z
...NO SVR TSTM AREAS FORECAST...
...SYNOPSIS/FORECAST...
WITHIN A HIGHLY AMPLIFIED LONGWAVE REGIME...A BROAD/INCREASINGLY
CLOSED UPPER TROUGH WILL BECOME ESTABLISHED EAST OF THE PLAINS ON
SUNDAY...WHILE THE CURRENT ROCKIES UPPER RIDGE IS SHUNTED EASTWARD
TOWARD THE PLAINS AHEAD OF AN UPPER TROUGH APPROACHING THE WEST
COAST.
IN THE EAST...WEAK DESTABILIZATION IN PROXIMITY TO AN OFFSHORE
BAROCLINIC ZONE/DEVELOPING FRONTAL WAVE MAY SUPPORT SOME TSTMS NEAR
THE OUTER BANKS OF NC/OFFSHORE MID ATLANTIC WATERS. OTHERWISE...THE
LARGE SCALE PATTERN AND THE PREVALENCE OF COOL/STABLE CONTINENTAL
TRAJECTORIES ARE EXPECTED TO GENERALLY PRECLUDE TSTM POTENTIAL EAST
OF THE ROCKIES.
AS THE CURRENT NEAR-COASTAL SOUTHERN CA UPPER LOW BEGINS TO BECOME
MORE PROGRESSIVE/ADVANCE NORTHEASTWARD...ISOLATED TO SCATTERED
THUNDERSTORMS ARE PROBABLE ON SUNDAY ACROSS MUCH OF THE
INTERMOUNTAIN WEST/GREAT BASIN TO THE FOUR CORNERS/SOUTHERN HIGH
PLAINS. WEAK WIND FIELDS AND/OR WEAK BUOYANCY WILL GENERALLY
PRECLUDE A RISK FOR SEVERE WINDS/HAIL.
