Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 347 PM EDT Thu Oct 27 2016 Valid 00Z Fri Oct 28 2016 - 00Z Sun Oct 30 2016 ...Heavy rain to impact the West coast for the next few days... ...Snow expected across interior New England and Upstate New York... A large upper level low is approaching the West Coast while drawing moisture up from what is currently Hurricane Seymour located in the Eastern Pacific. This tropical moisture that is being tapped is providing higher than normal moisture content across California and the Great Basin. At the surface, multiple boundaries will continue to push across these regions throughout the short term period. Showers and moderate to heavy rainfall can be expected across the Pacific Northwest for the rest of today and will increase throughout California and the Intermountain West/Great Basin tonight and into Friday morning. The Pacific Northwest will stay dry for the rest of Friday as another incoming surface front once again moves across California and the Intermountain West--which will contribute to the persistence of rainfall. By Saturday, the Pacific Northwest and northern California will see another wave of precipitation as another system approaches the West Coast. In addition, snow is expected across the Tetons on Friday. Looking to the East, a system tracking across the Ohio valley to New England will bring rain across the Mid-Atlantic, Northeast, and New England on Thursday. By Friday, the surface low will lift northward across New England and move toward Nova Scotia. For the most part, these regions will see light to moderate rainfall. In the higher elevations of Upstate New York and New England, several inches of snow can be expected especially on Thursday. By Friday, as the low tracks toward Nova Scotia, the interior portion of Maine could get measurable snow and will clear out by the weekend. An upper ridge will dominate the central portion of the U.S., keeping the weather quiet albeit temperatures well above average through the short term period. By Saturday, a front will begin to drop through across the northern Plains, bringing more fall-like weather for that region. Meanwhile, from the Plains to the Mid-Atlantic/Northeast temperatures will also be well above average for the weekend. Fanning Graphics available at www.wpc.ncep.noaa.gov/basicwx/basicwx_wbg.php
