SPC Nov 23, 2021 Day 4-8 Severe Weather Outlook

Day 4-8 Outlook Day 4-8 Convective Outlook NWS Storm Prediction Center Norman OK 0337 AM CST Tue Nov 23 2021 Valid 261200Z - 011200Z ...DISCUSSION... Guidance is in good agreement that a cold front will extend from the VA Tidewater south-southwestward to the FL Panhandle early D4/Friday. Continued eastward progression of this front will take it quickly off the remainder of the Eastern Seaboard and through much of FL on D4/Friday. Stable conditions are expected in wake of this front across the CONUS. A belt of moderate to strong mid-level flow will extend from the Pacific Northwest eastward through the northern Plains and then southeastward across central portions of the eastern CONUS. Several shortwave troughs are expected to progress through this stronger flow throughout the period, with each shortwave accompanied by a surge of dry continental air. As such, stable conditions are expected to prevail into at least early next week, with very low potential for severe thunderstorms. Read more LIVE: spc.noaa.gov
