A deep upper low will bring windy and much colder weather across alarge portion of the western U.S. as well as heavy mountain snow throughthe next couple of days.Heavy rain and possibly severe thunderstorms over southern Texas andMid-Mississippi Valley this evening will taper off as a higher threat ofheavy rain and severe thunderstorms quickly emerges over the north-centralPlains later on Monday.Severe thunderstorms and heavy rain threats will shift east into theOhio Valley and the Great Lakes on Tuesday.A rapidly intensifying cyclone will bring wind-swept rain across thenorthern High Plains Monday into Tuesday with wet snow across the high-elevations of the northern Rockies.A rather vigorous and deep upper-level low continues to push farther intothe western U.S. bringing windy and much colder weather across a largeportion of the region.  Heavy wet snow across the higher elevations of theGreat Basin and a good portion of the Pacific Northwest into the northernRockies will expand eastward into the central Rockies by tonight.  Thissystem will also bring quite a bit of wind, especially as a potent coldfront passes through the Four Corners region to Wyoming this evening,before spreading into the Rockies and much of the High Plains on Monday asa cyclone is forecast to intensify rapidly over the northern High Plains. An additional foot or more of heavy wet snow is expected to accumulatealong the Cascades in Oregon, as well as much of the northern and centralRockies through Tuesday.  In addition, severe thunderstorms are expectedto develop over the central Plains later on Monday ahead of a potent coldfront.  These thunderstorms will tend to intensify and track toward thenorth-northeast into the northern Plains and the upper Midwest Mondaynight where the potent cold front and a warm front collide.  Meanwhile,the center of the deep cyclone will then track across the northern Plainswith wind-swept rain impacting the northern High Plains on Monday.  Thecyclone center is forecast to meander over the northern Plains on Tuesdaywith the threat of heavy rain and high winds continuing acrossnorthern/eastern Montana while cold air wrapping around the deep cyclonewill support heavy wet snow over the northern Rockies.Meanwhile across the eastern two-thirds of the country, the strong tosevere thunderstorms found over southern Texas into the mid-MississippiValley are expected to gradually taper off into scattered showers andthunderstorms later tonight as the associated upper-level disturbanceweakens.  Farther east along the East Coast, some showers and embeddedthunderstorms over the Mid-Atlantic as well as a large swath of moderaterainfall over New England are expected to slide off the coast by Mondaymorning.  Meanwhile, the scattered showers and some embedded thunderstormsassociated with the weakened upper-level disturbance will slide eastwardand bring unsettled weather across the Tennessee Valley into the Southeastand up into the Mid-Atlantic states through Tuesday.  Also on Tuesday, theOhio Valley, Midwest, into the Great Lakes will see more widespreadshowers and possibly severe thunderstorms moving in as the lead frontalsystems from the northern Plains cyclone quickly arrive.The cool and dreary weather from the Mid-Atlantic to New England willgradually give way to warmer temperatures.  In contrast, much coolerweather will continue to penetrate the western U.S. with thepassage of the deep and vigorous upper trough/low along with windy andinclement weather closer to the elongated cyclone.  Finally, windy and dryconditions are forecast to raise the danger of wild fires across thesouthern Rockies through the next few days.
