VALID 061200Z - 071200Z
..NO SEVERE THUNDERSTORM AREAS FORECAST
..SUMMARY
SEVERE STORMS ARE UNLIKELY TUESDAY.
..SYNOPSIS
STRONG NORTHWEST FLOW WILL INTENSIFY OVER THE NORTHERN THIRD OF THE
US BEHIND A DEPARTING UPPER TROUGH OVER THE WESTERN ATLANTIC. A
SECONDARY LOW-AMPLITUDE TROUGH OVER SOUTHERN CANADA IS FORECAST TO
MOVE ACROSS THE UPPER GREAT LAKES AND INTENSIFY AS IS MOVES INTO THE
NORTHERN US. COOL MID-LEVEL TEMPERATURES BENEATH THE DEEPENING
TROUGH COULD SUPPORT ISOLATED THUNDERSTORMS ACROSS THE NORTHERN
GREAT LAKES LATE TUESDAY. OTHERWISE, THE COOL NORTHERLY FLOW AND
HIGH PRESSURE OVER THE EASTERN STATES WILL FAVOR DRIER AND MORE
STABLE CONDITIONS FOR MUCH OF THE REGION.
TO THE SOUTH OF THE SURFACE HIGH PRESSURE, SCATTERED THUNDERSTORMS
WILL AGAIN BE LIKELY OVER THE GULF COAST AND INTO CENTRAL AND
SOUTHERN FLORIDA AS NORTHEAST SURFACE WINDS PUSH A COLD FRONT
FARTHER SOUTH. SEVERE STORMS ARE NOT EXPECTED AS LAPSE RATES AND
VERTICAL SHEAR ARE FORECAST TO REMAIN WEAK.
A WEAK UPPER TROUGH AND A POCKET OF COOLER MID-LEVEL TEMPERATURES
MOVING OVER THE ROCKIES IS FORECAST TO STEEPEN LOW/MID-LEVEL LAPSE
RATES THROUGH THE DAY. WHILE ASCENT AND OVERALL MOISTURE WILL BE
MODEST, SUFFICIENT BUOYANCY COULD SUPPORT ISOLATED THUNDERSTORMS
OVER THE HIGHER TERRAIN.
