VALID 031200Z - 041200Z
..NO SVR TSTM AREAS FORECAST...
..SYNOPSIS...
MODELS INDICATE THAT THE PHASING OF NORTHERN AND SOUTHERN BRANCH
IMPULSES TO THE LEE OF THE ROCKIES WILL LEAD TO THE EVOLUTION OF A
AN AMPLIFIED...NEGATIVELY TILTED UPPER TROUGH OVER THE EASTERN U.S.
DURING THIS FORECAST PERIOD. AS THIS OCCURS...THE CENTER OF A LARGE
SURFACE RIDGE...ENCOMPASSING MUCH OF THE CENTRAL/EASTERN STATES...IS
PROGGED TO DEVELOP SOUTHEAST OF THE CENTRAL PLAINS THROUGH THE
WESTERN GULF STATES. MEANWHILE...SURFACE RIDGING IS EXPECTED TO
PERSIST ACROSS MUCH OF THE INTERMOUNTAIN WEST...TO THE EAST OF A
MID/UPPER HIGH CENTER...WHICH IS LIKELY TO SHIFT INLAND ...EAST
SOUTHEASTWARD ACROSS NORTHERN CALIFORNIA.
THE EVOLVING PATTERN IS EXPECTED TO MAINTAIN A DRY/STABLE
THERMODYNAMIC STRATIFICATION ACROSS MUCH OF THE NATION...RESULTING
IN LOW CONVECTIVE POTENTIAL...AND A NEGLIGIBLE SEVERE THREAT.
