What was reported inside it

Time	Report	Where	Remark
Jul 14, 5:26 PM MDT	HAIL 1	1 Ssw Bowman, ND	SOME QUARTERS... HAIL COVERING THE GROUND.

Local storm reports filed while the alert was in force, from inside its polygon or its counties.

Did it verify

Verified. The Iowa Environmental Mesonet's Cow matched one storm report to this severe thunderstorm warning; the first came 4 minutes after it went out.

Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.

The nearest sounding before it

Bismarck Municip, ND (KBIS), launched 12:00Z, 11.4 hours before the alert went out and 205 km from the middle of its area. This is the routine balloon launch nearest before it, the air the forecaster had in hand, not a measurement taken for the alert.

What forecasters said that day

The local office's own words before this severe thunderstorm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Bismarck, ND wrote its last area forecast discussion before this severe thunderstorm warning went out at Jul 14, 5:04 PM MDT, 18 minutes earlier.

Area forecast discussion, Jul 14, 5:04 PM MDT, 18 minutes before

Area Forecast Discussion
National Weather Service Bismarck ND
604 PM CDT THU JUL 14 2016

.UPDATE...
Issued at 604 PM CDT Thu Jul 14 2016

Showers and a few strong thunderstorms are moving across western
ND in advance of a weak shortwave trough late this afternoon. A
few of the storms in southwest ND have been strong due to MLCAPE
of 500-1000 J/kg and steep low-level lapse rates. Point forecast
soundings from the RAP over far southwest ND reveal 0-6-km bulk
wind shear near 40 kt, suggesting a non-zero risk of a marginal
severe storm through about 02 UTC. MRMS MESH data has verified
well with upstream storms in Montana this afternoon and so any
sustained signals of maximum hail sizes greater than about 1.30
inches in that guidance could garner a warning.

&&

.SHORT TERM...(This evening through Friday)
Issued at 301 PM CDT Thu Jul 14 2016

The short term will be dominated by weak instability and very
little wind shear so severe thunderstorms are not anticipated.
That said, a mid level vort center can be seen rotating through
northeast Montana and this has been kicking up some convection
that could produce some small hail and gusty winds this evening
across the west.

These will fade overnight as the daytime heating ends. The gfs/nam
seems to latch on to this feature across central and eastern North
Dakota Friday resulting in another round of convection friday in
the warmer hours of the day. Again shear is very weak with just enough
instability to fuel scattered non severe thunderstorms.

Highs friday will be in the 70s to around 80.

.LONG TERM...(Friday night through Thursday)
Issued at 301 PM CDT Thu Jul 14 2016

An active period begins the long term with multiple shortwaves
plowing across western and central ND Friday night through Saturday
night. These shortwaves are emanating from a closed upper low that
slowly moves along the southern Canadian border and into eastern
Alberta through Saturday night. For Saturday, SPC has southwest and
portions of south central ND in a Slight Risk area, with a Marginal
Risk for the rest of western and central ND. This correlates well
with the highest Cape/Shear environment. Will monitor for the
possibility of any upgrades within the Slight Risk and/or Marginal
Risk areas over the next 2 days.

Heights rebuild Sunday through Wednesday, as above normal
temperatures are forecast to commence. Dewpoints are forecast to
rise through the 60s next week as low level moisture advection
develops. Surface to 850mb southerly winds increase to around 40kt
at 850mb. Despite increased surface dewpoints, soundings next week
show a stout elevated mixed layer and thus it will be interesting to
see how/if enough cooling aloft from any shortwave can result in
surface based convection to develop. It appears that elevated
convection Monday night and Tuesday night might be the best
timeframe for thunderstorms.

Highs Monday will be in the 80s for most except in the far north.
Tuesday through Thursday highs will range from 85F to 95F. With
dewpoints in the 60s except in the southwest, expect a more humid
air mass especially in central ND.

&&

.AVIATION...(For the 00Z TAFS through 00Z Friday evening)
Issued at 604 PM CDT Thu Jul 14 2016

Showers and a few thunderstorms may produce localized sub-VFR
conditions in western ND this evening. There is another chance
of showers and thunderstorms on Friday afternoon and evening,
mainly over central ND. Again local MVFR or IFR conditions are
possible with that activity.

&&

.BIS Watches/Warnings/Advisories...
NONE.
