Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 402 AM EDT Fri Jul 3 2015 Valid 12Z Fri Jul 3 2015 - 12Z Sun Jul 5 2015 ***Stationary front remains over south-central U.S.*** ***Showers and storms from the Rockies to the East Coast*** ***Continued hot for the western U.S. through the weekend*** A quasi-stationary frontal boundary is expected to remain situated from Oklahoma to the Mid-Atlantic over the next couple of days. The heat and summer-like humidity will remain south of the boundary, and cooler conditions to the north. Multiple waves of low pressure are expected to form and track eastward along the front, along with more organized areas of rainfall and thunderstorm activity. The heaviest rain is expected to develop from Arkansas to the southern Appalachians, where one to three inches of rainfall is likely, along with locally higher amounts. A few severe thunderstorms will also be possible. For the western U.S., diurnally driven showers and storms will continue to be present each afternoon and evening across the Four-Corners region and extending southward into Mexico in response to monsoonal moisture in place. Isolated thunderstorms are also possible across the higher elevations of northern California, Oregon, and Washington. It should remain hot across much of the interior West, but some relief is coming from Washington state to Montana as a cold front is forecast to move through those areas.
