Area Forecast Discussion
National Weather Service Bismarck ND
357 AM CDT Wed Apr 26 2017

.SHORT TERM...(Today and tonight)
Issued at 244 AM CDT Wed Apr 26 2017

The main weather impact is snow setting up across the far
southern James River Valley this morning. Forecast soundings indicate
large scale ascent occurring within the dendritic growth zone
(-12c to -20C) along with steep mid level (700mb- 600mb) lapse
rates through much of the day today. This could produce snowfall
amounts between 3 and 6 inches by this afternoon across Dickey and
LaMoure Counties.

There are two factors that could limit snow totals. First,
freezing rain is possible early this morning before the column
becomes completely saturated. Second, as temperatures rise this
afternoon snow may mix with rain and surface temperatures may rise
briefly above freezing. This may make reaching 6 inches difficult,
but the combination of hazards still warrants heightened
awareness and caution.

The rest of forecast area will remain dry and cold with sky
conditions improving from mostly cloudy to mostly sunny, from west
to east in the afternoon. Highs will range from the upper 30s
Turtle Mountains south into the James River Valley to the 40s

.LONG TERM...(Thursday through Tuesday)
Issued at 244 AM CDT Wed Apr 26 2017

Overall a dry and cool pattern continues through Friday, with
temperatures moderating into the 50s Saturday through Tuesday. The
jet stream remains south of North Dakota which should lead to a
fairly tranquil pattern through Sunday. Monday and Tuesday the
pattern looks to become active again as the northern stream
eventually pushes a cold front through by the end of the extended
