CONCERNING...TORNADO WATCH 350...
VALID 302240Z - 310045Z
THE SEVERE WEATHER THREAT FOR TORNADO WATCH 350 CONTINUES.
SUMMARY...A LOCAL CORRIDOR OF GREATER TORNADO THREAT IS EVIDENT IN
THE DC/BALTIMORE REGION OVER THE NEXT 1-3 HOURS.
DISCUSSION...A NARROW ZONE OF FAVORABLY BACKED SURFACE WINDS, SOUTH
OF A WARM FRONT NEAR THE PA/MD BORDER, WILL BE THE MOST FAVORABLE
CORRIDOR FOR TORNADOES OVER THE NEXT 1-3 HOURS. LOCAL VAD DATA FROM
KLWX AND NEARBY TDWRS SHOW SUFFICIENT SRH FOR LOW-LEVEL MESOCYCLONE
DEVELOPMENT. A BOOKEND VORTEX WITHIN A LINEAR SEGMENT IN NORTHERN
VIRGINIA WILL CONTINUE NORTH-NORTHEAST INTO THIS FAVORABLE ZONE.
FARTHER EAST, ADDITIONAL DISCRETE STORMS WILL ALSO HAVE SOME
POTENTIAL TO PRODUCE A TORNADO. THE PRIMARY LIMITING FACTORS WILL BE
MODEST BUOYANCY, WEAK MID-LEVEL LAPSE RATES, AND LIMITED REMAINING
TIME FOR SURFACE HEATING.
