Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 208 AM EST Mon Jan 14 2019 Valid 12Z Mon Jan 14 2019 - 12Z Wed Jan 16 2019 ...Heavy precipitation returning to California and relatively uneventful weather across most of the nation... The recent winter storm across the Mid-Atlantic region has been a rather impressive event with heavy snow on the order of 10+ inches for some areas in northern Virginia and Maryland, and significant icing from freezing rain across western North Carolina and into southern Virginia. Now that this low pressure system is exiting the coast, our attention now turns to California and then the Intermountain West for the beginning of the work week. A deep Pacific trough off the West Coast will remain in place over the next few days with a frontal boundary approaching southern California Monday night, and additional shortwave impulses arriving through Tuesday. The result will be widespread rain with some localized flooding issues possible for the coastal mountain ranges. Heavy snow is likely for the Sierra Nevada and Siskiyou mountains of California, with amounts possibly exceeding a foot at the highest elevations. Elsewhere across the continental U.S., a mainly dry weather pattern is expected through Tuesday as a large surface high remains in place. A strong cold front drops southward across the Plains on Tuesday and into early Wednesday, bringing frigid temperatures to the Dakotas and the Upper Midwest by the middle part of the week. There should be enough moisture with this front to produce some mixed precipitation over the lower Great Lakes and snow showers behind the front over northern Michigan. Some showers are likely across southern Texas with some onshore flow from the Gulf of Mexico. D. Hamrick Graphics available at www.wpc.ncep.noaa.gov/basicwx/basicwx_ndfd.php
