Sundays SEVERE WEATHER OUTLOOK has NO organized areas of thunderstorms anywhere across our Nation for this afternoon or this evening. Sundays NATIONAL WEATHER FORECAST SUMMARY By: Forecaster, David Saurer Weather pattern is starting to quiet down quite a bit across the Nation on this Sunday, however, a few trouble spots are still warranting some concerns for travel and outdoor plans. We are still watching the strong cold frontal boundary sweeping into the Eastern Seaboard for today. We will continue to see developing and widespread rain showers along the front. The moisture is feeding into the precipitation from the Gulf of Mexico will continue to fuel for heavy rainfall with embedded thunderstorms across the Central Gulf Coast into the Southern Appalachians. FLASH FLOOD WATCHES and a FEW WARNINGS have been posted where some heavier and much more organized bans of rainfall continues to dominate along the surface wave with the boundary across the Tennessee Valley to the Mid-Atlantic. The northern portion of this surface wave will finally push out into the Atlantic by Monday AM, but the Southern half of the wave will stall out and will continue the soggy and wet pattern for the Southeast and Southern Mid-Atlantic to begin the New Years Holiday Week ahead. We are watching a ridge of high pressure, a rather strong one digging Southward from Canada and will filter in some of the coldest air thus far as the Arctic boundary continues to sag Southward through the North Central states on this Sunday. Some gusty winds and falling temperatures will be the story behind this Arctic boundary and will make for some very blustery conditions from the Pacific Northwest into the Central Plains. There is some energy aloft in the atmosphere over the region that will begin to trigger some widespread snow showers across the Pacific Northwest and Northern Rockies where WINTER STORM WATCHES AND WARNINGS have been posted. This Arctic blast is expected to continue to plunge Southward into the Southern Rockies and leaving much below normal temperatures for most of the Western half of the Nation by Mid-Week.
