VALID 041200Z - 051200Z
...NO SVR TSTM AREAS FORECAST...
...SYNOPSIS...
A COMPLEX UPPER LOW INITIALLY OVER THE GREAT LAKES REGION IS PROGGED
TO SHIFT NWD/NEWD WITH TIME...MOVING INTO ONTARIO/QUEBEC/NEW ENGLAND
THROUGH THE PERIOD. MEANWHILE...A SECOND LOW IS FORECAST TO MOVE
ACROSS THE GREAT BASIN/INTERMOUNTAIN WEST.
AT THE SURFACE...A LINGERING COLD FRONT ACROSS TX AND THE WRN AND
CENTRAL GULF COASTAL REGION WILL RETREAT NWD TOWARD THE RED RIVER
VALLEY AND NRN LA...AS LOW-LEVEL SLYS INCREASE AHEAD OF THE LARGE
WRN UPPER LOW PROGRESSING ACROSS THE ROCKIES. ALONG WITH SHOWERS
AND OCCASIONAL EMBEDDED LIGHTNING STRIKES ACROSS THE ROCKIES...WARM
ADVECTION NEAR AND N OF THE RETREATING FRONT SHOULD SUPPORT SHOWERS
AND STORMS ACROSS TX AND INTO THE GULF COAST STATES...AND PERHAPS AS
FAR N AS KS/NEB LATE. HOWEVER...WITH GENERALLY WEAK SHEAR S OF THE
RETREATING FRONT AND WEAK/ELEVATED INSTABILITY FARTHER N...SEVERE
THREAT APPEARS MINIMAL.
A FEW LIGHTNING STRIKES MAY ALSO OCCUR ACROSS PARTS OF ERN NEW
ENGLAND...AHEAD OF A STRONG SHORT-WAVE FEATURE ROTATING AROUND THE
MAIN UPPER LOW. MEAGER INSTABILITY EXPECTED ACROSS THIS AREA
PRECLUDES APPRECIABLE SEVERE POTENTIAL.
