A low pressure system tracking near the Gulf Coast will be the main weather maker for the next couple of days as much of the rest of the country will enjoy fine weather. Rain associated with the low pressure system will be moderate to heavy at times along with embedded thunderstorms across the interior Deep South and the Southeast through tonight and into Monday. Isolated Flash Flooding is possible from the Florida Panhandle to the Southeast Coast where between 2-4 inches of rain is forecast to fall by Tuesday morning. The low pressure system is forecast to intensify on Monday as it begins to move off the Southeast coast into the Atlantic. Winds are expected to become strong and gusty near the Carolina coastline Monday night as the rain possibly lingers into the early hours on Tuesday before tapering off by Tuesday morning. Meanwhile, warm air will continue to expand across the northern tier states where high temperatures are expected to reach into the 70s as far north as the southeastern corner of North Dakota by Monday afternoon to the south of an elongated low pressure system tracking along an arctic front across southern Canada. Arctic air that has been bottled up in Canada will be unleashed into the Plains on Tuesday behind the arctic front with low temperatures plunging into the single digits Tuesday morning near the Canadian border along with very gusty winds especially over the northern High Plains. The arctic plunge will reach into the Central Plains by Tuesday evening. Periods of snow and snow showers are expected from upstate New York into northern New England through tonight as a wave of low pressure passes through. The wave will move east and dissipate later on Tuesday followed by a warming trend down into the East Coast, across the Ohio Valley, mid-Mississippi Valley and the Southern Plains on Tuesday. Unsettled weather will continue across the Pacific Northwest with the passage of a Pacific front. Meanwhile, another cyclone farther south off the West Coast will develop and head toward the Southwest, bringing rain into southern California by Tuesday.
