Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 355 AM EDT Wed Jun 11 2014 Valid 12Z Wed Jun 11 2014 - 12Z Fri Jun 13 2014 ***Unsettled weather east of the Mississippi River*** ***Hot and humid from Texas to the Mid-Atlantic*** ***Developing surface low and cold front for Northwest U.S.*** Scattered showers and thunderstorms will be quite common throughout much of the Eastern U.S. through Thursday. The upper-level low currently over Illinois Wednesday morning is forecast to continue shearing out and will become absorbed by a trough over southern Canada. However, there will still be enough forcing aloft, along with a weak surface front, to generate areas of organized rainfall and embedded thunderstorm activity from the Deep South to the central Appalachians. Scattered showers and storms are also expected for the Mid-Atlantic and into the Northeast U.S. Some of the rainfall will be locally heavy and may be enough to result in some flooding issues. Across the central Plains and into the central Rockies, a weak cold front is forecast to drop southeastward and bring another round of showers and storms from the northern Rockies to the Upper Midwest. Hot and humid conditions are expected to continue through Thursday for the Deep South, Southeast, and into the Mid-Atlantic as this region will continue to have weak southerly winds and should remain south of the main frontal zone through this forecast period. Hot and dry weather will continue for the Desert Southwest, and pleasant conditions will continue for the California Coast. By the end of the week, a developing surface low and cold front over the Pacific Northwest and Inter-Mountain West will bring the chance of showers and isolated thunderstorms from Washington state to the northern Rockies by Thursday evening. This is in response to the upper level low currently over the northeast Pacific that is forecast to move inland over the Northwest U.S. This will also allow temperatures to cool off some in this region by Thursday.
