A frontal boundary extending from the southern and central plains to the Mid-Atlantic will result in scattered to numerous showers and thunderstorms today. An area of low pressure is forecast to develop along the front today across the central plains. As the low moves east, widespread showers and thunderstorms are expected by late this afternoon and into the evening from the southern plains to the mid-Mississippi valley. The area of thunderstorms will continue to spread east overnight into the Ohio valley and toward the Appalachians. Strong to severe thunderstorms as well as heavy rain are possible. The Storm Prediction Center is forecasting a slight to moderate risk of severe thunderstorms today and tonight - please refer to SPC's Convective Outlook products for further details. The potential for severe thunderstorms and locally heavy rain will linger into Sunday from much of Texas to the Ohio valley. Rain and thunderstorms will also spread into the Northeast on Sunday as the low pressure system lift north into Ontario. High pressure will strengthen across the West Coast states through the weekend, with dry conditions and well above average temperatures expected. High temperatures will rise well into the 80s today across the interior Pacific Northwest, with some areas reaching the lower 90s on Sunday. These temperatures are 10 to 20 degrees above average.
