Area Forecast Discussion
National Weather Service Great Falls MT
1120 AM MDT Fri Jul 16 2021

update aviation...
.UPDATE...

Overall the forecast remains largely on track. Expect high temps
across much of the area to range from the upper 80s to mid-90s,
which is likely being suppressed a bit by the smoke over the area.
There are some mid-level clouds over central MT this morning, and
some showers and thunderstorms are still forecast to develop this
afternoon. Not looking at high likelihood of severe, but will
mainly need to monitor for gusty wind potential and new
lightning-caused fire starts. -Kredensor

&&

.SYNOPSIS...

Isolated to scattered showers and thunderstorms will once again be
possible today and through the early evening hours tonight across
portions of the region, especially over the higher terrain of
Southwest and Central Montana. Temperatures warm through the
weekend, with the hottest day being on Monday of next week as
temperatures peak between 95 and 105 degrees.

&&

.AVIATION...
1120 AM MDT Fri Jul 16 2021 (16/18Z TAF period)

VFR conditions continue across the area. Mid level clouds and a few
light showers will continue across central MT. Widely scattered
thunderstorms will develop this afternoon. While thunderstorm
coverage will likely be low, gusty and erratic winds from this
activity will be more widespread. Areas of smoke/haze continue over
the region with surface visibility generally greater than 6SM, but
could be lower for a period this morning in areas directly downwind
of wildfire activity. db

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

&&

.FIRE WEATHER...

Thunderstorms of both wet and dry nature will once again be
possible across portions of Southwest through North Central
Montana, mainly along and southeast of a Lincoln, to Belt, to Hays
line. While the highest chance for isolated dry thunderstorms
exists across Southwest Montana today, a few storms producing
little rainfall can not be ruled out further north. Additional
chances for thunderstorms arrive back across the Northern Rockies
on Monday, with the best chance and coverage of storms expected on
Tuesday as monsoonal moisture lifts northeast from the Great
Basin and Desert Southwest. Temperatures will remain hot and
afternoon relative humidity low through much of next seven days,
with the hottest and driest days being on Sunday and Monday. -

.PREV DISCUSSION...
/ISSUED 509 AM MDT Fri Jul 16 2021/

Today through Saturday...subtle wave lifting northeast within
southwest flow aloft will provide another opportunity for showers
and thunderstorms across Southwest and portions of Central and North
Central Montana through the evening hours tonight, mainly along and
southeast of a Lincoln, to Belt, to Hays line. Best chance for these
showers and thunderstorms will be during peak heating hours, with
the best coverage of precipitation primarily residing over the
higher terrain. While isolated dry thunderstorms will be a concern
across the region once again, especially over Southwest Montana
along and south of the I-90 corridor, PWATs approaching 0.75"
(especially over Central and North Central Montana) and slow storm
motions are expected to lead to higher chances for wetting rains
today and early tonight. Given dry boundary and mid-level layers,
denoted within soundings (inverted-v's), concerns for gusty and
erratic winds approaching 45-55 mph do exist. High temperatures
today will be somewhat "cooler" than Thursday, but remain above
normal in the upper 80s to upper 90s. Saturday is expected to be
dry day across the Northern Rockies as the upper level ridge
amplifies across the western 2/3rds of the CONUS and into Canada,
with high temperatures warming into the low 90s to low 100s.

Sunday through next Friday...primary concern over the period will be
the heat and increasing thunderstorm chances. Upper level ridge will
continue to amplify through Monday, before subtle waves and
increasing monsoonal moisture begin to lift northeast within the
southwest flow aloft. Have maintained the Excessive Heat Watch for
eastern portions of Central and North Central Montana from Sunday
through Wednesday as this period continues to have the warmest
daytime highs, with marginal relief (i.e. low temperatures only
falling into the mid-60s to mid-70s) during the overnight hours.
High temperatures are still expected to peak during the day on
Monday, with most lower elevations rising to between 95 and 105
degrees. The warmest temperatures on Monday are expected across
eastern portions of Central and North Central Montana; however,
even areas like Great Falls, Helena, and Bozeman could reach or
exceed the century mark. Monsoonal moisture will begin to lift
northeast from the Desert Southwest and Great Basin during the day
on Monday, with isolated chances for showers and thunderstorms
across southern portions of Southwest Montana. Shower and
thunderstorm chances increase further in both potential and areal
extent on Tuesday, with the potential for some storms to produce
localized heavy rainfall given forecasted PWATs of over 1". Daily
chances for afternoon showers and thunderstorms linger across
eastern portions of Southwest through North Central Montana from
Wednesday through Friday as the upper level ridge slowly shifts
east. - Moldan
