303 PM MDT Thu Jun 27 2019
.SHORT TERM...valid for Fri and Sat...
The environment remains ripe for thunderstorms across the region.
The focus of most parameters, including high precip water values
is painted across northern Montana where helicity tracks from the
short term models are clustered. However, I am concerned over some
impulses working up through western Wyoming aimed right at
Yellowstone county later today. This is related to a jet let at
500 mb. Some models are suggesting a drying south wind may mix
down to the surface as this feature crosses our CWA late today.
However, if cap erodes first we could see some storms pop big.
Drier air evident in Paradise Valley and in some foothill
locations slowly working north.
Bottom line...isolated thunderstorms remain a possibility from
foothills north later today if cap breaks in time. If they
develop, could go severe based on the abundant CAPE and shear
over the region. They will probably have a defining back edge with
little additional development behind them in the evening. We will
aggressively update as time allows to remove mention of
thunderstorms and severe as dry air works north. Storms that form
will likely be north and east of Billings later this evening...and
eventually move out of our CWA overnight.
A weak front tries to move through the area early Friday supported
by thunderstorm outflow from NC Montana, but stalls out in the
morning with easterly winds increasing late morning and resetting
the atmosphere similar to Thursday. The difference may be that
many of the models develop a stronger cold pool from Friday
afternoon convection to the north which gives a better frontal
push into Friday evening that could be a stronger focus for storm
development. Right now larger scale models keep precipitation
chance low with isolated thunderstorm coverage. CIPS analogs
indicate a good probability for severe storms through most of the
forecast area for Friday based on the latest NAM forecast. Will
have to see how shorter range CAM models handle this set up as we
move into their time range. For now, further limited PoPs to the
western zones during the day. Temperatures Friday will be a bit
cooler than Thursday ranging from the upper 70s west to the upper
80s east. BT
.LONG TERM...valid for Sun...Mon...Tue...Wed...Thu...
Nothing new for the extended period. It looks seasonally unsettled
with multiple disturbances crossing the region bringing showers
and thunderstorms to the area most afternoons and evenings. An
upper low is progged to move into the Pac NW around the middle of
next week, with models differing in the timing of associated
shortwaves moving through the region. High temperatures look to
range from the 70s to 80s most days, with low temperatures in the
40s and 50s. BT
&&
.AVIATION...
Isolated showers and thunderstorms will begin to develop this
afternoon and evening. Erratic gusty winds are possible along with
hail and heavy rain. Localized MVFR/IFR conditions are possible
with these storms. Otherwise, expect VFR conditions to persist.
