Area Forecast Discussion National Weather Service Bismarck ND 257 PM CDT Thu Jun 29 2017 .SHORT TERM...(This evening through Friday) Issued at 240 PM CDT Thu Jun 29 2017 Cold front moving through western North Dakota this afternoon will be the focus for increasing thunderstorms across west into central North Dakota this afternoon and evening. While the threat for severe weather is low, an isolated large hail or gusty wind event is possible. Tonight the trend will diminish then end after midnight for all but the James River valley. Showers will linger across the Valley Friday then end by afternoon. Highs Friday will be cool, in the upper 60s and mid 70s. .LONG TERM...(Friday night through Thursday) Issued at 240 PM CDT Thu Jun 29 2017 The focus for the long term will be the very warm temperatures expected from the Fourth of July through Thursday. Highs will easily reach the mid 90s across the region with the GEFS plumes indicating the potential for highs in excess of 100. With little rain in sight the drought will likely worsen. With a broad ridge in place its likely any weak cold front will by dry and provide little relief from the hot weather. && .AVIATION...(For the 18Z TAFS through 18Z Friday afternoon) Issued at 200 PM CDT Thu Jun 29 2017 This afternoon, isolated to scattered thunderstorms will develop which may linger into the evening. Early Friday morning, localized MVFR cigs may develop over northern and eastern locations. Otherwise, VFR conditions will prevail. && .BIS WATCHES/WARNINGS/ADVISORIES...
