Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0154 PM CST Mon Dec 07 2020 Valid 072000Z - 081200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Severe thunderstorms are not expected across the U.S. mainland through tonight. ...20Z Update... Have introduced a general thunderstorm area for what is anticipated to be a low/isolated potential for thunderstorms the remainder of the afternoon into evening across central/eastern South Carolina and nearby small parts of Georgia/southeast North Carolina. Forcing for ascent related to a southeastward-digging vort max and thermodynamic profiles conducive for charge separation should allow for at least isolated/episodic low-topped thunderstorms as convection spreads east-southeastward through evening. ..Guyer.. 12/07/2020 .PREV DISCUSSION... /ISSUED 1003 AM CST Mon Dec 07 2020/ ...Discussion... Band of scattered showers and thunderstorms developing along a cold front has moved off the southeast FL coast. Otherwise, a large area of high pressure will maintain offshore flow and stable conditions across the U.S. through the remainder of the period.
