Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 313 AM EST Tue Feb 11 2020 Valid 12Z Tue Feb 11 2020 - 12Z Thu Feb 13 2020 ...A Slight Risk of excessive rainfall has been issued for eastern Texas, northern Louisiana, southern Arkansas, northern Georgia and the western Carolinas through Wednesday morning... ...Heavy snow is possible over parts of the Southern/Central Rockies... ...Another round of heavy rain to enter the Lower Mississippi and Tennessee valleys on Wednesday, with light-to-moderate snow possible over portions of the Midwest and Ohio Valley... A vast majority of the southern tier of the U.S. will have scattered to widespread rain and snow over the next few days. As a sprawling frontal boundary slowly moves eastward, pooling Gulf moisture from the Gulf of Mexico will fuel nearly continuous convection over this region. This environment will also be conducive for periods of moderate to heavy rainfall, especially over areas that have had several inches of rain in the past 1-2 weeks. With soils near saturation and more rain on the way, widespread flooding concerns will persist across the Gulf states and into the Appalachian region. Further west, heavy snow will be possible across portions of the Southern Rockies and particularly much of New Mexico through Wednesday morning with amounts of 6 to 12 inches are forecast. Local maximums in the highest terrain in Colorado and New Mexico may exceed 1 foot. Lower elevations across the Texas Panhandle and southwest Oklahoma could also see snow as the system slowly exits into the Southern Plains Tuesday. This aforementioned system will be responsible for the next round of heavy rain across the Lower Mississippi and Tennessee valleys on Wednesday. Additional rainfall amounts of 1 to 3 inches will be possible from northeast Texas to western Tennessee. Flash flooding will be a concern here once again due to the saturated ground and swollen streams/rivers. On the northern edge of the precipitation shield, snow will be possible from the Midwest to the Ohio Valley Wednesday and Wednesday night. Further north a strong cold front is forecast to enter the Northern Plains tonight and bring gusty winds, snow showers, and temperatures 10 to 20 degrees below average to the region.
