Area Forecast Discussion
National Weather Service Bismarck ND
333 AM CDT SUN JUN 26 2016

.SHORT TERM...(Today and tonight)
Issued at 240 AM CDT Sun Jun 26 2016

Latest water vapor imagery shows an upper low circulating over
southeast Manitoba with a corresponding northwest flow around the
low into North Dakota. A mid level shortwave trough emanating from
this low extends west into central Saskatchewan with an associated
weak cold front, mainly a wind shift, lying across southern Canada.
This subtle cold front/wind shift will reach the northern border
around 18z today, then sag south into the James River Valley by
00z Monday. Isolated showers generated along and ahead of the
frontal boundary this afternoon in the north will fade as they
slide south. However, another breezy day will be generated with
this weather pattern and frontal passage, as the James River Valley
nears advisory level wind speeds. For now, sub-advisory sustained
winds, that is less than 30mph, and gusts less than 45 mph. Will
forgo any headlines and let the dayshift adjust for any changes.

For tonight, the mid level shortwave trough slides into northern
North Dakota. Hints of a few showers along and ahead of the
shortwave noted on the NAM/GFS and this is reflected in the
gridded forecast.

Highs today will range from the upper 60s north where partly to
mostly cloudy conditions will reside, to the lower 80s south under
a sunny sky. Low temperatures tonight will be in the lower 50s.

.LONG TERM...(Monday through Saturday)
Issued at 240 AM CDT Sun Jun 26 2016

This long term period will be dominated by a quasi-stationary
h500 ridge from the southwest conus north through the mountain
provinces of Canada. An associated downstream trough over the
Great Lakes region will combine with the ridge and leave the
northern plains in general northwest flow aloft. Several
perturbations will be moving through the region bringing periodic
thunderstorm chances.

The best chances for thunderstorms will be Tuesday night and
Wednesday and again Wednesday night into Thursday. After Thursday
Canadian high pressure moves south bringing dryer and somewhat
cooler air with a only an isolated thunderstorm possible mainly
west Friday. Then scattered thunderstorms continue into the
weekend as surface low pressure develops in Montana bringing
southeast low level windflow and increased moisture.

highs through the period will be near or slightly below normal
with daytime high temperatures in the 70s to lower 80s and night
time lows in the 50s.
