Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 336 PM EDT Mon Oct 14 2019 Valid 00Z Tue Oct 15 2019 - 00Z Thu Oct 17 2019 ...Heavy to excessive rainfall possible across parts of the Deep South on Tuesday... ...Well-below normal temperatures to continue across much of the Northern Plains... A stationary front in the Gulf Coast states will slowly lift northward as a warm front tomorrow, increasing the coverage and amount of rainfall from the ArkLaTex eastward into central Mississippi and Alabama. This could lead to isolated flash flooding and WPC has issued a Slight Risk of Excessive Rainfall for much of the Southeast for Tuesday. Another system moving through the Upper Midwest this evening will act to increase rainfall ahead of the cold front, with an expanding area of initially light rain and some isolated storms from the western Great Lakes through the Midwest on Tuesday. This will push toward and over the Appalachians on Wednesday as the cold front sinks toward the Gulf Coast. Over the Carolina coastal plain, low pressure is forecast to deepen rather quickly off the southern NJ or DelMarVa coast which will increase rain/wind into New England overnight Wednesday. In the West, a primary then secondary front will bring rain and high elevation snow to Washington/Oregon Tuesday into Wednesday. 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. This may be record cold highs for the date on Tuesday from the Dakotas into Minnesota. Texas will see well-above normal temperatures on Tuesday (80s/90s) to be replaced by below normal temperatures on Wednesday (70s and even some upper 60s).By contrast, much of the interior West will see a warm-up by Wednesday as temperature rise into the 70s.
