10AM Day 2 Convective Outlook for Monday, February 23. NO THUNDERSTORM AREAS FORECAST
SUMMARY
Thunderstorms are not expected on Monday.
Synopsis
A powerful cyclone initially offshore of the southern New England coast will move northeastward toward Nova Scotia on Monday. Any remaining lightning activity with this system is expected to be offshore by the start of the period. Otherwise, cool, dry, and stable conditions in the wake of a cold frontal passage should preclude thunderstorm development across the central/eastern CONUS.
Elsewhere, shallow convection may persist into Monday morning across parts of the Olympic Peninsula of WA, but lightning potential should generally diminish with time. A midlevel shortwave trough will move from the Canadian Prairies toward the northern High Plains during the afternoon into Monday night, along the periphery of an upper ridge. Negligible moisture/instability is expected to limit thunderstorm potential with this shortwave.
