.SYNOPSIS...

Weather disturbances moving through a persistent southwest flow
aloft across the region will continue to provide daily afternoon
and evening opportunities for showers and thunderstorms through
the week, some of which may be severe. Temperatures trend above
average beginning Wednesday.

&&

.DISCUSSION...

The large scale weather pattern continues to feature a broad
upper level ridge centered over the central US with upper level
troughing along the west coast. Water vapor satellite imagery this
morning shows a larger piece of energy lifting through BC/AB with
multiple additional shortwave disturbances moving through the
offshore trough. Model guidance remains consistent in the big
picture trend of expanding the ridge west through the rest of the
work week, warming temperatures above seasonal averages by Wed and
beyond, while additional disturbances ejecting out of the W Coast
trough move around the periphery of the ridge across the Northern
Rockies and MT, maintaining a daily chance for thunderstorms each
afternoon/evening.

Clearing in the wake of the disturbance lifting through SW Canada
has allowed for some patchy low clouds and fog to develop early this
morning, primarily across north-central MT where surface moisture
remains elevated following yesterdays showers and thunderstorms. The
next embedded disturbance in SW flow aloft, located over OR this
morning, will lift across ID/MT this afternoon. Overall thunderstorm
coverage is likely to be less extensive this afternoon than previous
days, but moderate instability will be focused across central MT
with sufficient wind shear to support a few severe thunderstorms,
particularly across areas from the Little Belts east across Judith
Basin and Fergus counties. Deep moisture has shifted slightly east
from previous days but remains across eastern portions of central/N-
central MT for localized heavy rains with storms again today as
well. Will need to watch Fergus county where repetitive heavy rain
producing thunderstorms yesterday evening/overnight brought some
localized precipitation totals of 1-2", especially across the
Snowies.

Deeper low level moisture expands back west across most of north-
central/central MT Wed through Friday as the upper ridge strengthens.
Despite the ridging, additional disturbances moving through the
region combined with likely greater instability from surface heating
will result in additional chances for thunderstorms Wed-Fri.
Potential for severe thunderstorms increases some as well Wed and
Thur to cover most of the forecast area north of I-90.

Medium rage model ensembles are fairly consistent in support of
flattening the upper level ridge this weekend as upper troughing
lifts out from the NW US through southern Canada. Cluster analysis
however reveals there is still some uncertainty with the timing of
the wave. This will shift flow to westerly and shunt the deep
moisture that has been in place to the east of the region and
reduce the potential showers/thunderstorms. Temperatures may cool
slightly following the wave late this weekend, but longer range
model ensembles are in good agreement showing the amplification of
upper level ridging further west across the interior western US
next week, which would bring additional drying and perhaps the
beginning of mid-summer heat. Hoenisch

.AVIATION...
505 AM MDT Tue Jul 5 2022 (05/12Z TAF period)

Some areas of low clouds and fog developed early this morning across
north-central MT with a brief period IFR/MVFR cigs/vis through 15z
at some terminals. Otherwise, VFR conditions prevail with mid-high
clouds increasing and widely scattered thunderstorm development
expected this afternoon, primarily over central MT. Coverage of
thunderstorms will be less than previous days with KLWT most
likely to be impacted. Hoenisch
