Bitter cold will continue from the Great Plains to the Atlantic coast this weekend...beneath a broad trough carved out over the eastern half of the Nation. Temperatures across a large portion of the Upper Midwest...Ohio Valley...and Northeast will hardly climb out of single digits on Saturday before plummeting back down to below zero Saturday night. Conditions will improve a bit in the eastern U.S. on Sunday as temperatures begin to moderate and lake effect snows diminish...but high pressure sliding down from Canada will bring another blast of Arctic air into the north central U.S. Sunday night into Monday. Energy lifting out of northern Mexico...combined with moisture pulling northward out of the Gulf...will bring precipitation inland over Texas on Saturday. Precipitation will become more widespread as it expands northeastward across the Lower to Middle Mississippi Valley and Ohio Valley on Sunday...and the Arctic airmass in place over the eastern half of the Country will allow for freezing rain within the northern edge of the precipitation shield. Multiple weak and disorganized disturbances will move inland over the Western U.S. this weekend. The first will trigger light rains and higher elevation snows while crossing the Four Corners region...a second will bring rain into southern California...and finally a third will produce light to moderate precipitation across the Pacific Northwest. Also..light snows will continue to focus along a frontal boundary banked up against the northern to central Rockies. Gerhardt Graphics available at www.wpc.ncep.noaa.gov/basicwx/basicwx_wbg.php
