Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 213 AM EST Thu Dec 14 2023 Valid 12Z Thu Dec 14 2023 - 12Z Sat Dec 16 2023 ...Moderate to heavy snow and below average temperatures likely over portions of the Southern Rockies/High Plains through early Friday morning... ...Increasing Excessive Rainfall concerns over Florida... ...Northern tier and West warm up... A low pressure system beneath a digging upper trough will continue to produce snow over the mountains of southern Colorado and northern New Mexico as well as portions of the Texas/Oklahoma panhandles today. Anywhere between 4-8 inches of additional snow are expected through early Friday morning when the system is expected to move east. Scattered showers and thunderstorms are likely to spread from eastern and southern New Mexico east through western and central Texas/Oklahoma today. The low pressure system spreads more showers and thunderstorms into east Texas/Oklahoma and the western Gulf Coast on Friday. High temperatures will be below average across the Central/Southern High Plains today and tomorrow due to the aforementioned winter weather and associated cloud cover. Meanwhile, a quasi-stationary front draped across southern Florida will be the focus for showers and thunderstorms throughout the region beginning this afternoon. The excessive rainfall threat will increase each day culminating in a heavy rain event across the state on Saturday. There's an unusual amount of model uncertainty with this system due to the lack of agreement regarding the evolution of the upper-level pattern over the central U.S. over the next 48 hours. High pressure on both sides of the upper trough will support a warming trend for the West and northern tier of the country over the next few days.
