Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 344 AM EDT Sun May 26 2019 Valid 12Z Sun May 26 2019 - 12Z Tue May 28 2019 ...Cool for the West and Hot for the Southeast with more storms across the Plains... Weather conditions will continue to remain quite unsettled across the north-central U.S. going into the beginning of the week, with additional heavy rain and severe storms expected. This is in response to an anomalous upper level trough situated over the Intermountain West and a large upper level ridge anchored over the southeastern U.S. The next organized surface low develops across the western High Plains Sunday night and energizes the atmosphere for another organized round of strong to severe storms from the Texas Panhandle to southern Minnesota. The flash flooding threat will continue to exist across much of this same general area, with inundating rainfall over the past few days making the ground quite saturated and the prospects for an additional 1 to 2+ inches of rain only aggravating the ongoing flooding situation. The potent upper level low originating from the West coast on Sunday is expected to produce another surface low over the central plains by Tuesday morning. The heaviest rainfall from this storm system will likely be a little farther north from eastern Wyoming to the Upper Midwest. There will be a dichotomy of temperature anomalies across the U.S. through Memorial Day. Expect readings to be below normal across the northern plains, and also for the Intermountain West and Desert Southwest. With the anomalous upper level low tracking southward along the West Coast and then the Four Corners region by Monday night, temperatures will be rather pleasant across the normally hot lower elevations of the Desert Southwest, and quite cool across the higher elevations. Across the Deep South and the Carolinas, record high temperatures will continue to be possible for the remainder of the Memorial Day weekend, with highs soaring well into the 90s and lower 100s for some areas, perhaps challenging a few records for the month of May!
