What forecasters said that day

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

NWS Billings, MT wrote its last area forecast discussion before this high wind warning went out at Apr 6, 4:33 AM MDT, 7 hours 40 minutes earlier. Its key messages:

  • Warm and dry ahead of a cold front on Tuesday. Low to moderate chance of showers with the front.
  • Brief period of gusty to strong crosswinds accompany the front, across the foothills west of Billings Tuesday afternoon/evening.
  • Gusty to strong winds in southeast MT, greatest along the Dakotas border on Wednesday. Moderate chance of gusts exceeding 50 mph.

.KEY MESSAGES...
- Warm and dry ahead of a cold front on Tuesday. Low to moderate
  chance of showers with the front.

- Brief period of gusty to strong crosswinds accompany the front,
  across the foothills west of Billings Tuesday afternoon/evening.

- Gusty to strong winds in southeast MT, greatest along the
  Dakotas border on Wednesday. Moderate chance of gusts exceeding
  50 mph.

&&

.DISCUSSION...
Through Sunday...

Ridging continues into Tuesday, with mostly dry conditions. There
is a backdoor cold front dropping into the east, models are
showing a low chance for showers there today. Any accumulations
with precipitation will be negligible though. Look for high
temperatures in the upper 30s to mid 50sF today (coolest in the
east). With the backdoor front, breezy conditions will be felt in
the east today into Tuesday afternoon with winds gusting 20 to 30
mph out of the south-southeast.

An upper low developing over Canada will bring the next system to
the region, Tuesday through Wednesday. A cold front associated
with the low will bring a brief period of gusty to strong winds
across the foothills west of Billings Tuesday evening. Pre-frontal
temperatures will be 10-20F above normal, with highs in the 60s
and 70sF. This is a tricky wind setup, as ensembles have a strong
signal for wind gusts exceeding 50 mph Tuesday afternoon/evening
for the foothills west of Billings. Because this is less of a
synoptic setup, the likelihood of gusty to strong crosswinds all
day on Tuesday is lower. The east-west gradient that generally
aids a strong crosswind event for the US-191 corridor, looks to be
fairly weak. Additionally, 700mb winds are not all that strong
ahead of the front, 35 to 45 knots. Mixing does not seem to be an
issue, with lapse rates in excess of 7.5C/km. Soundings do show 50
knot winds or greater above 700mb ahead of the front for Big
Timber and Harlowton, though the westerly direction is less
favorable for Harlowton. For Livingston, this will be a hybrid
event with strong mixing and westerly 700mb winds. The probability
for gusts of 50 mph or greater for Livingston is moderate at this
time. The main push of strong winds looks to be with the fronts
arrival, currently late Tuesday afternoon/ early Tuesday evening.
Because of this, a High Wind Watch remains in effect from Big
Timber through Judith Gap for gusts to 60 mph.

Across the rest of the area, look for gusts in the 20s to 40 mph
range. Low relative humidities are also forecast with the windy
and warm conditions. As a result of this, there will be elevated
grass fire concerns for the plains/foothills around and west of
Billings where recent precipitation was generally a tenth of an
inch or less.

As the upper low moves through southern Canada / into northern
Montana Tuesday evening, the cold front will move across the rest
of the forecast area, bringing a low to moderate chance of
showers. This will not bring significant, widespread rainfall. The
chance for appreciable moisture is low, though heavier showers
could bring a tenth of an inch of rain or more. A few rumbles of
thunder may accompany the front as well.

The upper low looks to continue it's journey through the Canadian
Plains and Dakotan Plains, NW winds wrapping around the low look
to bring gusty to strong winds to eastern MT Wednesday afternoon.
The latest model guidance has at least a 60% chance of 50+ mph
wind gusts in Custer, Fallon, and Carter Counties.

Thursday and beyond, a return to ridging or perhaps slightly
unsettled flow appears likely, though the chance for precipitation
is currently low. High temperatures are currently forecast to be
in the 40s and 50sF to end the week before 60s and 70sF arrive for
the weekend.
