Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 457 PM EDT Sat Jul 04 2015 Valid 00Z Sun Jul 05 2015 - 00Z Tue Jul 07 2015 ...Wet weather and possible flooding to continue through Sunday for portions of the South... ...Strong storms and possible flash flooding for parts of the northern Plains on Sunday... ...Relief from the heat for parts of the West into the Plains... Warm and humid conditions will remain for locations to the south of a weakening, quasi-stationary front, extending westward from the Mid-Atlantic to the middle Mississippi River Valley. Given locations from Arkansas through northern Mississippi, Alabama and into the southern Appalachians have been anomalously wet over the past week, any additional rain may contribute to more flooding and flash flooding. By Monday, there will be less upper level support for heavy rain down across the southern U.S., which should allow folks to begin drying out from recent heavy rain. Temperatures will climb well into the 90s from eastern Montana and Wyoming into the central and northern Plains today, but the passage of a strong cold front will drop high temperatures for these locations into the 70s for Sunday. However, locations into portions of the Dakotas and Minnesota will have to deal with a bout of strong to severe storms with possible flash flooding late in the day Sunday as the cold front moves through before relief from the heat can will be seen. The cold front will continue south and east on Monday into parts of the upper Midwest and the Plains bringing possible strong/severe storms with it, with much cooler temperatures in the wake of the front. Across the western U.S., little relief from the heat will be seen for portions of the interior Northwest, where high temperatures near 100 degrees will again be seen for parts of the Columbia Basin through Tuesday. This is due to a relatively blocked pattern across the West, which will also feature scattered, diurnally driven thunderstorms across the Rocky Mountains and Desert Southwest.
