Day 4-8 Outlook
Day 4-8 Convective Outlook NWS Storm Prediction Center Norman OK 0249 AM CST Fri Jan 29 2021 Valid 011200Z - 061200Z ...DISCUSSION... A deep upper trough is forecast to exit the East Coast on D4/Monday, with upper ridging (and associated stable conditions) moving across the Plains and eastern CONUS in its wake. Consequently, thunderstorms potential will be very low. A strong shortwave trough is expected to move over the West Coast late D5/Tuesday or early D6/Wednesday. Guidance varies on the evolution of this system, but some severe potential could manifest if a slower, more southerly track is realized. However, model differences and forecast range currently limit predictability, leading to low forecast confidence.
