Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 420 AM EDT Fri Nov 02 2018 Valid 12Z Fri Nov 02 2018 - 12Z Sun Nov 04 2018 ...Severe weather threat continues to shift to the East Coast on Friday... ...Widespread rainfall with possible flooding expected from the Mid-Atlantic to the Northeast Friday into early Saturday... ...Widespread precipitation from the Northwest to the northern Plains, with strong gusty winds over the Rockies on Friday... A slow-moving frontal boundary extending from the Northeast into the Gulf of Mexico will remain a focus for rains and storms through Friday. Some of these storms may be strong to severe, with the Storm Prediction Center continuing to highlight a Marginal Risk for severe weather from Upstate New York and southern New England to Florida on Friday. Heavy rain will also be a threat, especially along and ahead of an area of intensifying low pressure lifting north along the front from the Mid-Atlantic into the Northeast. These heavy rains may pose flash-flooding concerns, with the Weather Prediction Center highlighting the threat with a Slight Risk for excessive rainfall from the Mid-Atlantic to New England. As the low lifts into Atlantic Canada and the front pushes offshore, expect the heavy rainfall and severe weather threat to wane across much of the eastern U.S. on Saturday. However, windy and wet conditions, including some mixed precipitation in the mountains, is expected to continue across Upstate New York and northern New England through late Saturday. Currently, High Wind Watches are in effect for Saturday for portions of Upstate New York and New England. Out west, a frontal system will continue to support widespread precipitation as it pushes east from the Northwest into the northern and central Rockies and Plains on Friday. This will include some high elevation snows for the northern and central Rockies, as well as for portions of eastern Montana and and western North Dakota where Winter Weather Advisories and Winter Storm Watches have been issued. Strong gusty winds are also a concern across the mountains, with High Wind Watches currently in effect for portions of the Rockies from western Montana to southern Wyoming. This system is expected to push further east into the Plains on Saturday before reaching the Mississippi valley on Sunday. This will bring widespread precipitation from the upper Midwest to the southern Plains and lower Mississippi valley, including showers and storms late Saturday into early Sunday from eastern Oklahoma and Texas into the lower Mississippi valley. Some mixed precipitation from North Dakota into northern Minnesota and the upper Great Lakes region can be expected as well.
