1PM Day 3 Convective Outlook for Sunday, January 11. NO THUNDERSTORM AREAS FORECAST

SUMMARY

Thunderstorms are not expected across the U.S. on Sunday.

Discussion

An amplified midlevel trough will advance eastward across the Northeast and Mid-Atlantic through the period. Strong forcing for ascent and steepening deep-layer lapse rates preceding the trough could result in an isolated lightning flash with low-topped convection overspreading the Mid-Atlantic. However, low confidence in this scenario and expected limited coverage precludes a TSTM area at this time. Upstream, an expansive cool/dry air mass will limit thunderstorm potential across the CONUS.
