SPC 0830Z Day 3 Outlook
Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 1250 AM CST Sat Jan 09 2021 Valid 111200Z - 121200Z ...NO THUNDERSTORM AREAS FORECAST... ...SUMMARY... Little if any thunderstorm activity is expected across the continental U.S. on Monday. ...Synopsis... A shortwave trough will lose amplitude as it moves from the lower MS valley toward the Mid Atlantic on Monday, with a broad belt of strong mid and upper-level southwesterlies over the southeastern states. At the surface, a stable air mass will remain in place over land, despite a weak surface low moving across northern FL and southern GA into Tuesday morning. Dewpoints downstream of the low are only expected to reach the 45-50 F range, resulting in very little SBCAPE for thunderstorms. While weak warm/moist advection will occur above 850 mb across GA and the Carolinas Monday night, forecast soundings show very little elevated instability. As such, thunderstorm chances will be minimal. ..Jewell.. 01/09/2021
