Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 328 AM EST Thu Nov 05 2015 Valid 12Z Thu Nov 05 2015 - 12Z Sat Nov 07 2015 ...Heavy snow possible across the higher elevations of the central Rockies... ...Flash flooding possible across portions of the southern plains and Mississippi valley through Saturday... ...Severe thunderstorms possible on today for portions of Texas and Oklahoma... The scattered to widespread snow across the West will slowly taper off today in the wake of the relatively strong low pressure system that moved through the Rockies and the High Plains. This system will continue to track across the central portions of the CONUS this afternoon and evening, then across the East on Friday. As the system moves into the central/northern plains on Thursday, sufficient cold air will be in place on the northwestern edge of the precipitation area for rain to mix with or change to snow from portions of western Nebraska into parts of the Dakotas. Snow accumulations through Saturday morning along the Rockies will range from 1 to 6 inches. Light amounts are forecast for eastern North Dakota and northwestern Minnesota. Scattered to widespread showers will accompany the front over the northern states Friday and into Saturday. Mixed precipitation will be possible over the Great Lakes and surrounding areas in the wake of the cold frontal passage. Numerous showers and thunderstorms are expected to develop along the southern flank of this system today and Friday as it passes through the Southern Plains. Some of the thunderstorms may turn severe in Texas and Oklahoma. Please refer to the Storm Prediction Center's Convective Outlook for additional information. Heavy rain is forecast along the same axis of that of the severe storms. Rainfall amounts of 1 to 3 inches will be common from the Texas Hill country to the Ozarks Mountains over the next few days. Isolated amounts up to 4 inches will be possible along the I-35 and I-45 corridor. Another swath of heavy rain will span from southwest Louisiana to northeast Alabama -- amounts ranging from 1 to 4+ inches. Flash flooding will be possible in these areas through the end of the work week. Another upper-level disturbance will move into the northwestern U.S. on Thursday, bringing another round of snow to the northern Intermountain states. This system will be moving relatively quickly, which will keep snowfall amounts in check -- but heavy snow will be possible at some of the higher elevations of the northern Intermountain states. Rain showers will also be possible across the lower elevations of the Pacific Northwest tonight into early Thursday in association with this system.
