Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 300 PM EST Sun Nov 18 2018 Valid 00Z Mon Nov 19 2018 - 00Z Wed Nov 21 2018 ...Light to moderate snow accumulations for portions of the upper Great Lakes and Northeast through Tuesday... ...Elevated threat for wildfires continues for northern and southern California... ...Poor air quality continues over portions of California, Oregon and Washington... The overall weather pattern across the lower 48 will remain relatively quiet into the early part of this week with no major storm systems to note. Out West though, the subdued weather will continue to feature high pressure over the Intermountain West with cold fronts and precipitation remaining offshore due to a blocking upper ridge over the West Coast. The result will be poor air quality with smoke and low level pollutants along with a continued elevated threat for the spreading of wildfires in southern and northern California given gusty winds and low relative humidities. There is an ongoing threat across northern California in conjunction with the currently burning Camp Fire in the foothills of the Sierra Nevada, but the threat for additional wildfires will shift into southern California for Monday as gusty winds subside some up north. Farther north in the Pacific Northwest, air stagnation alerts will continue through Tuesday as surface ridging continues. A couple of cold fronts will work their way toward the East Coast through Tuesday bringing below average temperatures from the north-central U.S. and Great Lakes region to Texas and the central Gulf Coast. Light to locally moderate snow will accompany two weak areas of low pressure forecast to track across the Great Lakes tonight into Monday and with low pressure organizing off of the New England coast for Tuesday. Through the day on Tuesday, lake enhanced snow showers should bring generally 3 to 6 inches of snow for portions of far northwestern Wisconsin into the U.P. of Michigan and far northern lower Michigan. Upstate New York into central New England could see similar amounts through Monday morning with the heaviest expected for portions of central New England. Across the South, low pressure along a slow moving frontal boundary in the western Gulf of Mexico will keep coastal Texas into the lower Mississippi Valley with showers and occasional thunderstorms in the forecast through Monday night. The heaviest rainfall should remain offshore with no widespread flooding concerns over Texas or Louisiana into the middle of the week.
