Area Forecast Discussion
National Weather Service Bismarck ND
925 PM CDT Tue Jun 5 2018

.UPDATE...

Issued at 925 PM CDT Tue Jun 5 2018

Severe t-storm watch out through early Wed morning. Overall
besides the watch no big changes to our thinking for tonight.

UPDATE
Issued at 640 PM CDT Tue Jun 5 2018

No major deviations from the previous thinking for tonight. We're
still on track for scattered severe storms to develop this evening,
roughly between 01-03 UTC across south central ND. Next forecast
update will be for severe watch issuance, which SPC indicated if
issued would happen between 01-02 UTC.

&&

.SHORT TERM...(This evening through Wednesday)
Issued at 226 PM CDT Tue Jun 5 2018

Tonight's severe weather threat over south central North Dakota
and the southern James River Valley highlights the short term.

An upper level ridge will move across the state through the
afternoon as a northern stream shortwave approaches from the
west. While most of the energy from this wave will stay north of
the international border, two separate pieces of energy are
evident on water vapor and visible satellite imagery. One impulse
was associated with some scattered convection across eastern
Montana, and a stronger impulse was located over eastern Wyoming.
At the surface, a weak cold front was extending south southwest
from low pressure located over central Manitoba to near Hettinger.

Showers from the impulse over Montana will make their way into
western North Dakota through the afternoon, moving northeast.
Ahead of the cold front, the warm sector will likely remain capped
through the afternoon, with very warm surface temperatures
(reaching into the low to mid 90s across south central and the
James River Valley), neutral to slightly rising heights, and very
little large scale forcing. Additionally, RAP soundings suggest a
modest, yet deep elevated mixed layer over KJMS and KBIS through
the afternoon.

With very little cloud cover across the south central and
southeast, temperatures in the upper 80s to the lower 90s, and
dewpoints in the upper 50s to the lower 60s, the atmosphere will
become moderately unstable with MLCAPE values reaching as high as
1500 to 2500 J/kg. By 00z the impulse moving northeast out of
Wyoming will have accelerated across western South Dakota,
bringing with it height falls. This evening, the cold front will
likely be draped from near Carrington, southwest to Bismarck, to
near Elgin.

As heights begin to fall and we cool aloft, both waves will allow
convection to initiate along or behind the cold front in the 00z
to 03z time frame. High Resolution guidance is in relatively good
agreement with regards to convective initiation timing and general
location. The first storms are likely to develop near Carrington
where capping will be at a relative minimum, before building
southwest along the rest of the frontal zone. When storms do
initiate, they are likely to become rapidly severe with plenty of
MUCAPE and deep layer shear ranging from 35 to 45 knots. A
consistent signal has been present among SPC HREF ensemble
members regarding strong updraft helicity with these storms,
painting neighborhood probabilities of UH greater than 100 m2/s2
in the 50 to 70 percent range, generally in the window from 02z to
05z. This signal suggests that any storms that do form will
exhibit strong supercell characteristics. Low level wind fields to
not appear very favorable for tornadic development, but strong
rotating updrafts will be favorable for the production of very
large hail, possibly greater than 2 inches in diameter, damaging
wind gusts, and heavy rainfall. Also of note is that several
convection allowing models have been consistently showing UH
values greater than 200 m2/s2, including both the operational and
the experimental HRRR cores. Convection should begin to diminish
in intensity around 06z, but showers and thunderstorms may linger
across the south through 09z to 11z.

.LONG TERM...(Wednesday night through Tuesday)
Issued at 226 PM CDT Tue Jun 5 2018

Ridging builds back in again on Wednesday with pleasant weather
and highs in the 70s with some lower 80s across the south. Another
impulse approaches late Thursday, bringing the next chance for
showers and thunderstorms Thursday afternoon into Friday morning.
SPC has southwest North Dakota in a slight risk for Day 3. A
deepening longwave trough and stronger wave will approach the
state on Sunday and will bring our next chance of widespread
showers and thunderstorms late Sunday and into Monday. This will
also be a system we will have to monitor for severe weather
potential as details continue to come into view, as the pattern
has consistently been advertised on the GFS and ECMWF. 00z CIPS
analog guidance was also showing a signal for some severe weather
during this time period. Temperatures will generally remain in the
70s and 80s through the extended time period.

&&

.AVIATION...(For the 00Z TAFS through 00Z Wednesday evening)

Issued at 640 PM CDT Tue Jun 5 2018

Showers and thunderstorm will develop across south central and
southeastern ND this evening, possibly impacting both KBIS and
KJMS. Strong to severe storms will be possible at both terminals
from 02-06Z. Winds associated with any storms will be gusty and
very erratic. Overall VFR conditions are expected through the
period, though any strong thunderstorm will likely produce IFR or
lower conditions for a period this evening/early Wed morning,
again for KJMS and KBIS.
