Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 345 AM EDT Tue Oct 15 2019 Valid 12Z Tue Oct 15 2019 - 12Z Thu Oct 17 2019 ...Heavy to excessive rainfall possible across parts of the Deep South on Tuesday... ...Developing coastal storm to bring heavy rain and strong winds to parts of the Northeast late Wednesday into Thursday... ...Well-below normal temperatures to continue across much of the Northern Plains, with well above normal spreading across the West... A frontal boundary draped across the Gulf Coast states will slowly lift northward, with showers and thunderstorms likely from the Lower Mississippi Valley to the Southeast on Tuesday. Locally heavy to excessive rainfall is possible. Another system advancing through the Midwest on Tuesday will bring rain and storm chances along and ahead of the cold front. This will push through the Ohio Valley and into the East by Wednesday, while the cold front sinks towards the Gulf Coast. Over the Carolina coastal plain, low pressure is forecast to deepen rather quickly off the Mid-Atlantic coast, reaching a position near or just off the New England coast by Thursday morning. This storm system will bring heavy rainfall and gusty to possibly storm force winds from portions of the northern Mid-Atlantic to New England Wednesday night into Thursday. Meanwhile out West, a couple of surface fronts will bring rain and higher elevation snows to the Pacific Northwest Tuesday into Wednesday, with mountain snow developing by early Thursday in parts of the Northern Rockies as well. The Northern Plains to Upper Mississippi Valley will stay chilly through the period with daytime highs as much as 10 to 30 degrees below normal, especially on Tuesday. Near to above normal temperatures from Texas to the Ohio Valley on Tuesday will be replaced by below normal temperatures on Wednesday on the backside of the advancing cold front. Temperatures across the interior West will be warming through the period with daytime highs rising into the 70s for many, with 80s to 90s across parts of the Southwest.
