Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 242 AM EDT Sun May 28 2017 Valid 12Z Sun May 28 2017 - 12Z Tue May 30 2017 ...Severe thunderstorms and locally heavy rain possible from the southern plains to the Ohio valley and Mid-Atlantic... ...Hot conditions expected to persist for the interior Pacific Northwest... An upper-level low is forecast to deepen across the Great Lakes over the next couple days as a surface low pressure system brings showers and thunderstorms to much of the central and eastern U.S. Showers and thunderstorms are expected today and tonight ahead of the associated cold front, from the southern plains to the lower and mid Mississippi valley to the Great Lakes and Mid-Atlantic. Some thunderstorms could be severe across these areas. Please refer to products issued by the Storm Prediction Center for further details on the severe weather threat. Locally heavy rain is also possible. On Monday, the front will bring numerous showers and thunderstorms to the Northeast, with scattered showers and storms farther south across portions of the Mid-Atlantic, the Southeast, and the southern plains. High pressure aloft is forecast to persist across the western U.S. promoting continued warm and generally dry conditions. A cold front will move into the northern Rockies later today through Monday, with scattered showers and thunderstorms possible. The hottest conditions are expected across the interior Pacific Northwest, where high temperatures today and Monday are forecast to be 10 to 20 degrees above average. Temperatures will rise well into the 90s for portions of interior Washington and Oregon. Ryan Graphics available at
