6AM Day 1 Convective Outlook for Monday, February 23. NO THUNDERSTORM AREAS FORECAST

SUMMARY

Thunderstorms are not expected today or tonight.

Discussion

Convective potential will be virtually nil today. While isolated lightning flashes were noted overnight east of Long Island and near coastal southern New England, lightning-conducive thermodynamic profiles, in the northwest quadrant of the deep offshore cyclone, will continue to quickly diminish and shift away from the coast. In the Pacific Northwest, a few lightning flashes occurred overnight in coastal Washington, and a sliver of weak buoyancy was observed in the 12z UIL/Quillayute, WA sounding. However, a trend toward shortwave ridging and less-lightning-conducive thermodynamic profiles should effectively end such thunderstorm potential.
