A storm system that has vacationed in Baja and northern Mexico is now returning to the states and will bring rain and thunderstorms to Texas, Oklahoma, Arkansas and parts of Louisiana on its Sunday journey northeastward. Moisture from the Pacific and the Gulf will add juice to this storm and some locations could pick up just over an inch of rain. High pressure firmly in place along the East Coast will try to block the eastward progression of the rain shield but by Monday the zone of showery rains will slide eastward, extending from southeast Texas and Louisiana to Tennessee. The previously-mentioned high pressure system will bring northeasterly-flow clouds from off the Atlantic over the beaches of eastern Florida on Sunday with only a slight chance of a sprinkle. The rest of the South will reap the benefits of the persistent high pressure with partly to mostly sunny skies and pleasant afternoon temperatures both Sunday and Monday. Sunday afternoon highs will range from the 70s in south Texas and the Florida Peninsula to the 50s in Oklahoma, Arkansas, Tennessee and North Carolina. The 60s and 70s will try to nudge farther north on Monday.



A cold front followed by increasingly colder, arctic-tinged air will put an end to the latest warm spell over the Plains and Upper Midwest by Sunday. Highs will range from the single digits and teens in North Dakota and northwest Minnesota to the 30s and 40s from Kansas to Upper Michigan. Temperatures will be as much as 5 to 15 degrees below average in the Dakotas, but still 10 to 20 degrees above average across the Great Lakes, mid-Mississippi Valley and Ohio Valley. The cold-mild temperature contrast will continue on Monday with high temperatures 10 to 15 degrees below average over the Plains and northern Minnesota and 5 to 15 degrees above average across Lower Michigan, the mid-Mississippi Valley and the Ohio Valley. Thanks to the storm from out of northern Mexico, clouds and showery rains will sweep northward ahead of the cold front on Sunday from Kansas and Missouri to Wisconsin and Upper Michigan, fringed by a change to snow as the colder air arrives from Nebraska to western Upper Michigan. On Monday the rain will shift eastward in Lower Michigan and the Ohio Valley with a fringe of snow and sleet from eastern Nebraska and northeast Kansas to northern Michigan. Tuesday and Wednesday as a vigorous storm comes out of the Rockies, there could be a significant swath of snow from the central Plains to Michigan so stay tuned.



With high pressure anchored over the region, the Northeast and Mid-Atlantic will enjoy another day of mostly sunny skies and temperatures 5 to 15 degrees above average (30s northern Maine to 50s and low 60s Virginia) on Sunday. This early spring fling will continue to melt the mounds of left-over snow from the blizzard that occurred 2 weeks ago. The stubborn high pressure system will linger into Monday keeping the skies partly to mostly sunny and the temperatures 5 to 15 degrees above average. Clouds will be on the increase Monday night as the high breaks down and the storm in the Midwest advances toward the Appalachians. Rain will make its way into the eastern Great Lakes region by Tuesday. Wednesday will be a wet day with snow from Upstate New York to Maine and rain across the Mid-Atlantic.



Two systems will impact the West in varying degrees on Sunday. The first will be fairly weak and swing from Nevada and California into Utah and Arizona producing a broad area of light snow and a few pocket of rain from eastern Oregon, southern Idaho and southernmost Montana to northern portions of Arizona and New Mexico. Right behind this first disturbance is a stronger one that will bring locally heavy rain and snow (snow levels will be very low to just below 1000 feet in western Washington) to the Pacific Northwest by Sunday. This storm will swing across the Pacific Northwest bringing accumulations as high as a foot and a half to the snow-starved alpine regions before dropping south into the Great Basin and the central Rocky Mountains by Monday bringing fresh powdery snow to the mountains (up to 2 feet in the Wasatch) with rain in the valley locations. Southern California on Sunday will deal with cloudy skies and a small chance for patches of drizzle or light showers from L.A. to San Diego. The clouds and slight risk for light showers will linger into Monday in Southern California.
