Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 453 PM EDT Sun May 3 2015 Valid 00Z Mon May 4 2015 - 00Z Wed May 6 2015 ***Warm weather pattern across much of the country through Monday*** ***Precipitation to become more widespread by Sunday night and Monday*** The eastern third of the country will enjoy a relatively quiet weather pattern through Monday afternoon with not much in the way of organized precipitation. A surface high over the western Atlantic will extend westward from the East Coast to the Deep South, thus keeping sky conditions sunny to partly cloudy. In the temperature department, highs are forecast be 10 to 20 degrees above average across much of the Mid-Atlantic and Northeast on Monday. This will also be the case for the central Plains and Midwest states, with widespread temperatures in the 80s expected. Moisture has started to increase across much of the Intermountain West and Great Plains. A cold front will continue moving southward through the Great Basin this evening and should become nearly stationary tonight into Sunday. This boundary will serve as a focus for showers and thunderstorms across the Four Corners region and the Rocky Mountains for the beginning of the week, and much of this activity will be diurnally and orographically enhanced. Another front crossing the northern Plains and Upper Midwest will also result in a band of showers and storms as moisture gets drawn northward into this system. By Tuesday, more showers and storms are expected to develop from the central Plains to the Ohio Valley, and some of these storms could become severe at times.
