Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 453 PM EDT Fri Jun 13 2014 Valid 00Z Sat Jun 14 2014 - 00Z Mon Jun 16 2014 ...Widespread red flag warnings have been issued across the Central Great Basin...Southwest...and Southern Rockies... ...Severe weather and flash flooding will be possible ahead of a cold front pushing out into the Plains and Upper Midwest... ...Conditions should finally begin to dry out across the Northeast and Mid-Atlantic states... An unseasonably deep upper trough carving out over the Western U.S. will trigger scattered shower activity from the Pacific Northwest to the Northern Rockies over the next few days. Farther south...widespread red flag warnings have been issued across the Central Great Basin...Southwest...and Southern Rockies...where gusty winds beneath the anomalous trough will combine with persistently dry conditions to heighten the threat for wildfires. At the leading edge of the upper trough moving in over the Western U.S....a strong cold front will trigger showers and thunderstorms as it pushes out across the Northern/Central Plains on Saturday and moves into the Upper/Middle Mississippi Valley by Sunday. Convection will be developing in a very moist and unstable environment...giving storms the potential to become organized and contain severe weather. Heavy downpours within the storms will also make flash flooding a concern. Numerous showers and thunderstorms will continue to light up ahead of a cold front crossing the Appalachians Friday evening...but the front should clear the Mid-Atlantic coast Saturday morning and leave behind a refreshing drop in dew points. The southern portion of the front is expected to stall out and linger over the Southeast...keeping showers and thunderstorms in the forecast until the boundary eventually weakens on Sunday. Conditions will also be slow to clear out over northern New England...where a surface low spinning up off the Northeast coast will trigger scattered shower activity through Sunday morning.
