1PM Day 1 Convective Outlook for Friday, January 30. NO THUNDERSTORM AREAS FORECAST
SUMMARY
Thunderstorms are not expected today or tonight.
20Z Update
The previous forecast (see below) remains on track.
Synopsis and Discussion
A large-scale upper trough will amplify over the central/eastern CONUS through tonight. In response, a surface low will gradually deepen and develop northeastward along/near the Gulf Stream, while remaining offshore of the Carolinas. Any thunderstorms associated with the warm sector of the surface cyclone should also remain offshore. A separate mid-level shortwave trough will overspread parts of the Pacific Northwest and British Columbia today. While showers/bands of precipitation are forecast to move inland, negligible instability is expected to limit thunderstorm potential.
