Area Forecast Discussion
National Weather Service Bismarck ND
240 PM CDT Fri Sep 14 2018

.SHORT TERM...(This evening through Saturday)
Issued at 239 PM CDT Fri Sep 14 2018

Thunderstorm potential highlights the short term forecast.

Currently, a stationary frontal boundary extended from a surface low
over eastern South Dakota northward across Wahpeton/Fargo into
northwestern Minnesota. Another secondary boundary in the form of a
cold front extended from the Turtle Mountains to near Bismarck to
near Hettinger. At upper levels, a longwave trough over the West
Coast was keeping a southwesterly flow aloft across the northern
Rockies and Northern Plains today.

Upper level impulses within the flow aloft were keeping scattered
showers across northwestern and north central ND today. And the
coolest air remained behind the secondary cold front over far
northwestern ND where temperatures remain in the 50s/60s this
afternoon, while highs in the low to mid 70s were reported across
the remainder of western and central ND.

This afternoon and tonight, the upper level west coast trough digs
south into California, forcing the upper level energy impulses over
northern ND farther north into Canada as h500 heights rise over our
region. Thus scattered rain showers in northern ND are expected to
wane with time this evening. Meanwhile, the aforementioned surface
stationary boundary becomes more of a strengthening warm front,
extending southwest-to-northeast from a low over Wyoming, across
South Dakota, into southeastern ND by Saturday morning. As this
occurs, a strengthening low level jet is forecast to develop,
bringing chances of showers and thunderstorms to south central and
southeastern North Dakota this afternoon and evening. Bulk shear
values are fairly high at 50+ knots, but CAPE is weak at up to
around 100-400 J/kg. Thunderstorms possible but severe weather not
anticipated.

The CAMs develop scattered thunderstorms from Bismarck to Jamestown
and south late this afternoon and evening, with the convection
moving north and east out of central North Dakota later
tonight...with little in the way of showers Saturday morning.
Along with the developing low level jet, a mid-level thermal cap
develops northeastward, building from the western high plains into
southern and eastern North Dakota later tonight and Saturday.
This should keep showers and thunderstorm chances confined to
northeastern North Dakota - and moreso into northern Minnesota and
southern Canada.

Looking at a mostly cloudy day on Saturday, with low clouds in the
morning giving way to mid level clouds in the afternoon. Thus high
temperatures should only reach the mid 60s northwest to mid 70s
along the South Dakota border.

.LONG TERM...(Saturday night through Friday)
Issued at 239 PM CDT Fri Sep 14 2018

A warm Sunday southwest, south central and across the James River
Valley...followed by a cool down next week...and a chance for
widespread rains mid-week across the area highlights the extended
forecast.

Saturday night the Wyoming surface low lifts northward into eastern
Montana, and the associated surface warm front moves northward to
the Canadian border by daybreak Sunday. As this occurs, the
northward leading edge of the low level jet moves northward as well,
with the continuing expansion of the mid level thermal ridge. This
should lead to confining showers and thunderstorms to mainly the
northern half of ND. Increasing CAPE with increasing surface to h850
dewpoints will be realized as well, but the best forcing should be
north of the Canadian border Saturday night, and especially into
Sunday.

On Sunday, a small but vigorous upper level shortwave moves
northeast across Montana into western ND and into Manitoba. In
response, the Montana surface low develops/moves eastward across the
Dakotas as a cold front. Gusty southerly winds ahead of the front
will allow warmer, humid air to continue to advect into the eastern
Dakotas. Behind the front, gusty west/northwest winds will develop,
ushering in drier air Sunday afternoon. Sunday looks to be the last
summer-like day across the state...at least for the next several
days. Look for highs in the mid and upper 80s - perhaps 90F - in the
far south central and James Valley, with highs in the 70s over
the northwest and north central.

Cooler weather next week as the upper level flow becomes more zonal,
then the upper level flow develops into a western US and Rockies
trough, with a large-scale surface low deepening over the central
Plains. This scenario will allow plenty of showers and thunderstorms
for the central Plains through the Mississippi Valley, and
overrunning showers and possible thunderstorms for North Dakota
Wednesday and Thursday. Look for high temperatures next week to be
mainly in the 60s, with lows mainly in the mid 30s and 40s. Frost is
possible over northwestern and north central ND beginning Monday
night.

.AVIATION...(For the 18Z TAFS through 18Z Saturday afternoon)
Issued at 1233 PM CDT Fri Sep 14 2018

Rain showers will continue across northwest North Dakota through the
day. Scattered rain showers and thunderstorms are expected to
develop late this afternoon and evening across south central North
Dakota and the James River Valley affecting KBIS and KJMS. MVFR/IFR
stratus will move northward into southern North Dakota tonight,
affecting mainly KJMS-KBIS-KDIK.
