Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 501 PM EDT Sun Jun 28 2015 Valid 00Z Mon Jun 29 2015 - 00Z Wed Jul 01 2015 ...Well above average temperatures to continue across the Pacific Northwest... ...Portions of the Midwest, Gulf Coast and Eastern Seaboard remain the favored areas for rain... With a strong ridge of high pressure anchored over the western U.S., unseasonably warm temperatures will persist for much of the Pacific Northwest and northern Rockies. Numerous locations could observe afternoon highs exceeding 20 degrees above the daily average. A weak cold front will make its way toward the west coast Monday afternoon and evening, but is expected to fizzle out before coming ashore. There is just enough lift to generate some scattered showers and possibly a few thunderstorms, however with limited available moisture, precipitation amounts will likely be minimal for Washington and Oregon. Temperatures will cool slightly, but are expected to remain 10 to 15 degrees above normal. A combination of amplified ridge out west and the upper low retrograding near Hudson Bay will keep the eastern thirds of the U.S. unsettled as multiple cold fronts move through Sunday afternoon through Tuesday. Showers and thunderstorms are expected for portions of the Midwest, Central Plains, and the Mississippi River valley through Tuesday. The Storm Prediction Center is forecasting an area of enhanced risk for severe thunderstorms across much of the middle Mississippi valley extending west into eastern portions of Kansas. Please refer to the Convective Outlooks issued by the SPC for further information on the severe weather threat. A very slow moving system over the Eastern Seaboard will keep temperatures slightly cooler than normal. Showers and thunderstorms are expected for the Gulf Coast, Southeast and the Mid-Atlantic. A nearly steady rain is forecast for the New England States through Tuesday as a slow moving low pressure system lifts northeast through the area.
