No major systems are expected to affect the country through the weekend, but some will see precipitation and even unseasonably warm temperatures for some as well especially on Saturday.
In the east, a trough moves through this region today and Saturday producing scattered snow showers in the eastern Great Lakes and Northeast, and mainly a few rain showers further south in the TN and OH River Valleys and parts of the Mid-Atlantic. The majority of accumulating snow will occur off the lake effect snow belts in northern and eastern MI, northeast OH, northwest PA, and western NY.
In the west, a system builds into the Pacific Northwest this evening and moves southeastward through the weekend affecting areas such as Seattle and Portland tonight and Saturday, Reno and Idaho Falls Saturday night and Sunday, Salt Lake City and Cheyenne Sunday and Sunday night, and Denver by overnight Sunday.
Another area of precipitation is expected to develop Sunday evening and overnight producing mainly rain showers near a cold front from the Ozarks northeastward to the eastern Great Lakes.
Finally, for Leap Day on Saturday, a little taste of spring is expected in the form of highs 15-25 degrees above average in the Plains with 50s as far north as the Canadian border, 60s as far north as far southern SD, and 70s as far north as far southern NE.
