1PM Day 1 Convective Outlook for Monday, February 23. NO THUNDERSTORM AREAS FORECAST
SUMMARY
Thunderstorms are not expected today or tonight.
20Z Update
No changes needed to the previous forecast.
Synopsis
A pronounced mid-level trough and associated deep surface low will continue to progress further into the Atlantic, leading to upper ridging over the Intermountain West and broad northwest flow across the central CONUS today. Surface high pressure and an accompanying continental polar airmass will overspread much of the U.S. east of the Rockies through the period, limiting thunderstorm potential.
