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.
