Low pressure over the Central Plains will move slowly into the Middle Mississippi Valley by early Friday morning and to the Northern Mid-Atlantic Coast by Saturday. As this system moves eastward, unseasonably cold air to the north will allow for a stripe of light to moderate wet snow from Nebraska to parts of the Northeast by Friday evening. The highest snow amounts east of the Rockies are currently expected to be across southern Iowa into portions of northern Illinois, where eight to twelve inches of snow could fall by Friday morning. Winter Storm Warnings and Winter Weather Advisories have been issued here. By Friday night and Saturday, a mix of rain and snow is forecast to enter the Mid-Atlantic and Northeast. Upwards of eight inches could accumulate across the higher elevations of northern Pennsylvania, with three to six inches of snow possible across parts of Upstate New York and western Massachusetts. Meanwhile, temperatures across much of the Central/Southern Plains to parts of Midwest and Northeast will be 10 to 30 degrees below average. Freeze Warnings and Frost Advisories stretch across portions of the Mid-Atlantic and central Kansas through Friday morning. In contrast, southern Florida will continue to experience near record high temperatures with highs in the low 90s. Snell Graphics available at www.wpc.ncep.noaa.gov/basicwx/basicwx_ndfd.php
