Area Forecast Discussion
National Weather Service Bismarck ND
1048 PM CDT Sat Jul 4 2020

.UPDATE...
Issued at 1046 PM CDT Sat Jul 4 2020

Update for severe thunderstorm watch for western North Dakota
until 4 AM CDT. Storms across eastern Montana will continue east
into western North Dakota now through early Sunday morning. Main
threats will be large hail up to the size of ping pong balls and
gusty winds to 60 mph.

UPDATE Issued at 901 PM CDT Sat Jul 4 2020

Will allow for the remainder of the Severe Storm watch and Flash
Flood watch to expire with this product issuance as all convective
activity in our southeast has pushed south into South Dakota.

Attention now turns to the west where storms across eastern
Montana will track into in a few hours.

UPDATE
Issued at 749 PM CDT Sat Jul 4 2020

Will trim off Kidder and Emmons from the watch. Other counties
will likely be removed before 9PM CDT.

UPDATE
Issued at 715 PM CDT Sat Jul 4 2020

Main edit this evening/overnight was to fine-tune POPs better, to
focus on the ongoing convection in our southeast slowly pushing
south and east, and to time the arrival and eastward progression
of showers and storms moving into western ND later this evening
and across the area overnight. Severe Thunderstorm Watch and Flash
Flood Watch remain in effect. Will take a look at removing some
counties in the next hour or two from the SVR Watch, possibly the
FF Watch as well.

UPDATE
Issued at 511 PM CDT Sat Jul 4 2020

With heavy thunderstorms across my four southeast counties, we
opted to issue a Flash Flood Watch for Logan, McIntosh, LaMoure,
and Dickey counties until midnight.

UPDATE
Issued at 445 PM CDT Sat Jul 4 2020

Severe thunderstorm watch number 328 is in effect now through this
evening for far south central ND and for much of the James River
Valley. Will monitor radar trends for storms southeast now through
early evening and for storms moving in from Montana later this
evening for further product updates late this afternoon and
through this evening. Storms may also cross into far northern ND
this evening so have kept POPs here. Removed POPs for much of
central North Dakota this evening as most likely scenario for
those areas will be overnight showers/storms.

&&

.SHORT TERM...(This evening through Sunday night)
Issued at 147 PM CDT Sat Jul 4 2020

There will be two main areas of strong to potentially severe
storms that will impact western and central North Dakota this
evening and tonight. One will likely be ongoing over the James
River Valley, with thoughts generally unchanged from the previous
forecast update.

Another area of storms will be approaching the southwest, ahead of
an advancing cold front around or after 03z, likely in the form
of a forward propagating MCS. Strong instability will be in place
as this area of storms spreads north and east across the state
through the night. Shear will generally be marginal (effective
values 30 to 40 knots), but should be sufficient for a handful of
severe wind and/or hail reports. This activity will likely
diminish as the low level jet relaxes Sunday morning.

The front will move into the eastern third of North Dakota by
Sunday afternoon where strong storms are expected to fire once
again. The best chance of a severe storm will be across the
southern James River Valley, with large hail and damaging wind
gusts being the main threats.

.LONG TERM...(Monday through Saturday)
Issued at 147 PM CDT Sat Jul 4 2020

For the remainder of the period, a mid level trough will set up
across the Pacific northwest, sending multiple shortwaves into the
Northern Plains. Nearly every day will see at least some chances
for showers and thunderstorms. However, at the moment it appears
that the strongest wave will come through Tuesday night through
Wednesday, a period we will have to keep an eye on closely for
severe weather and heavy rain potential. Additionally, 12z CIPS
analogs show a fairly strong signal for severe weather during this
time frame. Plenty of time for things to change with regards to
specific details, but this wave is currently forecast to have a
better CAPE/shear overlap than we have seen in recent events.
Thus, the active stretch continues with above average temperatures.

&&

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

Issued at 715 PM CDT Sat Jul 4 2020

Thunderstorms continue across the James Valley and may still
impact KJMS through 02-03Z before the threat ends for the evening
hours. More storms will enter the west late this evening and push
east across western and central ND overnight/Sunday morning.
Latest TAF forecast attempting to capture the timing of this
activity better. These storms may also produce damaging winds and
large hail. Any stronger storm may lead to brief MVFR/IFR
conditions, but VFR conditions are expected outside of any storms
or heavier showers.

NONE.
