Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 247 PM EST Tue Nov 12 2019 Valid 00Z Wed Nov 13 2019 - 00Z Fri Nov 15 2019 ... Widespread record cold spreading from the Plains eastward toward the East Coast... ...Active Lake Effect snows continue downwind of the Great Lakes... ...Persistent warm and dry weather over the West will continue to elevate fire weather concerns for portions of southern California... A vast majority of the central and eastern U.S. will have below normal temperatures has the Arctic airmass spreads from the Plains into the Ohio/Tennessee Valley and eastward. Hundreds of locations may set new records during this time. By Wednesday morning, low temperatures in the teens and 20s will be common along much of the East Coast, the Ohio Valley, and down as far south as the upper Texas coast, making it feel like the middle of winter for these areas. Freeze and Hard Freeze warnings are in effect from the Texas Coast to coastal South Carolina. Temperatures will begin to warm up on Thursday once the expansive high pressure system migrates offshore the New England Coast. Meanwhile, snow currently falling across portions of the Tennessee Valley, the Appalachians and the Northeast will begin to taper off this evening- while the lake effect snow will persist into Wednesday morning. Rain, spanning from Florida to New England, will continue to track east-northeast offshore this evening. Additionally, an upper-level disturbance arriving from northern Mexico will increase the chance of rain along the Gulf Coast as a coastal front forms just offshore. Rain and snow chances will increase across the Pacific Northwest and the Interior as an upper-level disturbance moves inland. Amounts are expected to be on the lighter side as the system quickly passes through the Plains Wednesday and into the Great Lakes region by Thursday. For the Great Basin/Rockies region, warmer and drier conditions are expected to prevail which will maintain an increased risk for spread of wildfires.
