Area forecast discussion, Jul 16, 10:54 PM MDT, 2 hours 56 minutes before
Area Forecast Discussion
National Weather Service Great Falls MT
1054 PM MDT Sat Jul 16 2022

..Aviation Section Updated...

.SYNOPSIS...

Isolated thunderstorms will diminish this evening, with another
hot day and a few strong thunderstorms possible on Sunday
afternoon. For Monday, it will be very windy, with the potential
for severe storms once again, mainly east of a line from Havre to
Helena. Expect above normal afternoon temperatures from Tuesday
through Friday as well.

&&

.UPDATE...

Isolated convection NNE of Helena (moving NE) should gradually
diminish in coverage and intensity through the next hour. However,
it may hold together long enough to impact the Moors Mountain fire
response area.

Inherited large-scale forecast looks generally good for the rest of
the night. Another hot day for Sunday before significant wind
returns to the area Monday.

&&

.DISCUSSION...

Tonight through Sunday...A few isolated thunderstorms are
possible this evening, mostly south/east of a line from Helena to
Lewistown. On Sunday, a slightly stronger upper level disturbance
will move northeastward through Southwest MT during the
afternoon/evening hours. Another round of thunderstorms will
accompany this disturbance. However, the potential for some storms
to be strong/severe is there. Thus we are in a marginal risk for
severe storms on Sunday. Otherwise, afternoon temperatures will
likely be in the upper 90s to near 100 degrees for most lower
elevation locations.

For Monday, a strong upper level disturbance will move eastward
across the northern portions of our CWA during the day. Strong
winds are expected to develop behind this disturbance. Thus the
remainder of our region has now been placed under a high wind
watch, with wind gusts around 60 mph possible across our CWA.
Additionally, ahead of this disturbance, a line of
showers/thunderstorms will move through. Some of these storms
could be severe on Monday, with the main threat being damaging
wind gusts. Temperatures will not be as hot in the Cut Bank area
Monday, but temperatures still likely above normal as you move
towards our east portions of the CWA.

Tuesday through Saturday...Weak upper level ridging will build over
Central MT from Tuesday through Thursday, allowing for very warm air
to quickly move back into Central MT. Generally dry conditions can
be expected during this period. On Friday, a quick moving upper
level disturbance will move across the northern portions of the CWA,
which could allow for a few thunderstorms to develop over North
Central MT. However, confidence/PoPs are low for this event at this
time. On Saturday, a return to mostly dry and very warm temperatures
is progged. Brusda

&&

.AVIATION...
1054 PM MDT Sat Jul 16 2022 (17/06Z TAF period)

A thunderstorm moving across Central Montana this evening has had a
history of producing gusty and erratic winds of between 35-45kts as
it moved over/near the KHLN and KGTF terminals. This thunderstorm
will continue to move east across the remainder of Central Montana,
and will affect the KLWT terminal through 05-08z Sunday. Outside of
the gusty/erratic winds and lightning threats, VFR conditions are
expected with convective cloud bases around 10,000ft agl.

Otherwise, VFR conditions are expected across Southwest through
North Central Montana through 18z Sunday, thereafter scattered to
numerous thunderstorms are expected to develop and lift northeast
across the Northern Rockies, especially along and southeast of a
KHLN, to KGTF, to KHVR line. Thunderstorms during the afternoon and
evening hours on Sunday will be capable of producing gusty and
erratic winds of between 30-50kts. Mountain obscuration is likely at
times during the afternoon and evening hours on Sunday due to
thunderstorm activity. - Moldan

Refer to weather.gov/zlc for more detailed regional aviation
weather and hazard information.

&&

.FIRE WEATHER...
Hot afternoon temperatures, along with some thunderstorm activity
is expected today and Sunday. On Monday, a strong upper level
disturbance will move from west to east across the region. Expect
strong surface winds to develop on Monday afternoon and then
continue into Monday evening. With fuel conditions running near or
a bit moist, no fire highlights are planned for Monday at this
time. It is likely going to take the next few days and the winds
on Monday to cure the grasses and make them more receptive for the
potential of large fire growth. Brusda
