Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 243 PM EST Fri Nov 09 2018 Valid 00Z Sat Nov 10 2018 - 00Z Mon Nov 12 2018 ...Dangerous fire weather conditions to linger for portions of northern and southern California through the weekend... ...Another shot of cold air for the central to southern High Plains on Sunday after a brief warm up on Saturday... ...Heavy snows for portions of the Great Lakes... ..Heavy rains may result in flooding concerns for portions of the Northeast early tonight... High pressure over the Great Basin and relatively low pressure along the West Coast has been supporting a strong pressure gradient and ideal fire weather conditions given offshore winds amid a very dry airmass for parts of California. The pressure gradient and gusty winds are expected to weaken some tonight although another cold front and subsequent high pressure will move through the Great Basin late Saturday into Sunday setting up another round of strong winds for portions of northern and southern California by Sunday morning. The greatest threat for the spreading of wildfires will be across the northern third of California from the Sierra Nevada to the Coastal Ranges and portions of southern California including the Los Angeles and San Diego metropolitan areas both Saturday and Sunday. The coldest air of the season is currently in place over the central to northern Plains, but Saturday will feature a brief warm up with high temperatures forecast into the lower 50s to lower 60s from western Nebraska/Kansas into eastern Colorado. As another cold front surges down the Front Range Saturday night into Sunday, a return to colder temperatures along with snow is in the forecast on Sunday along and east of the southern to central Rocky Mountains into the High Plains. Out East, a surface cyclone will continue to develop with brief but heavy rain moving from the northern Mid-Atlantic into southern New England early tonight. Some of the rain could cause flooding from northern New Jersey into and across southern New York into southern New England with 1-2 inches possible. Cold air wrapping around the low-mid level center of the system will support locally heavy lake effect snow from the U.P. of Michigan into northern Wisconsin and portions of Lower Michigan through early Saturday morning. The storm system will quickly move northeast into Quebec for Saturday evening but cold and blustery conditions will be left in its wake across portions of New York into New England on Saturday with light to moderate lake effect snow east of Lakes Erie and Ontario. Slowly improving conditions are forecast through Sunday for the Great Lakes to Northeast. Otto Graphics available at www.wpc.ncep.noaa.gov/basicwx/basicwx_ndfd.php
