...New AVIATION...

.SYNOPSIS...
Issued at 100 PM MDT Wed Jun 26 2024

It seems that the summer monsoon season is in full swing. Showers
and storms will be common this afternoon and again Thursday before
coverage decreases a bit Friday. High temps will drop some
Thursday thanks to clouds and rain but shoot back up Friday. The
weekend and much of next week will feature rather warm days with
daily chances for showers and storms.

.DISCUSSION...
Issued at 100 PM MDT Wed Jun 26 2024

Moisture continues to increase under our ridge with the morning
EPZ sounding revealing PW values of 1.31". This is right in line
with what models have been advertising for the past few days and
we will see these numbers climb a bit more into tonight and
tomorrow. With this enhanced amount of moisture, expect storms
that pop up the rest of today and tomorrow to be very impressive
rain makers. Early convection over the Sacramentos today has
already seen cells produce rain rates close to three inches per
hour. The steering flow today remains rather light under the
ridge, so combining high precip rates with slow storm motion will
enhance the Flash Flood potential throughout the afternoon and
evening.

Shortwave energy will eject out of the Pacific Northwest and
cross to our north Thursday which will help to weaken the upper
ridge and keep precipitation chances across the region as we
continue to tap the rich moisture supply. There could be somewhat
better dynamics Thursday, so locations that miss out on rain
today will get another chance tomorrow. I do expect Thursday to
begin with a fair amount of debris cloud cover left over from
todays activity. This will work in tandem with lowering heights
and additional storms to bring temps back down several degrees
Thursday. However some slightly drier air will follow the upper
shortwave, which will allow for another rather hot day Friday.

As we settle into the weekend and the early stages of next week
things are looking more and more like a true monsoon across the
region. The upper ridge is progged to slowly build eastwards
allowing for southerly flow into the desert southwest. 700-500mb
moisture profiles show healthy surges into the region as PW values
in general look to remain well above normal.

mostly cloudy skies and lingering light showers possible. VFR
conditions will mostly prevail for the rest of the evening through

.FIRE WEATHER...
Issued at 100 PM MDT Wed Jun 26 2024

Showers and thunderstorms will remain possible across the entire

gusty erratic winds and heavy rainfall. The 20ft winds will be
generally light to breezy and temperatures will stay above
normal. Tonight recovery will be good to excellent. For Thursday,
showers and thunderstorms will continue especially in afternoon
and in the evening. The 20ft winds will continue to be light to
low end breezy and the temperatures somewhat above the average.
Thursday overnight recovery will be fair to excellent. For the
rest of the period, there will be continued chances for showers
and thunderstorms especially in the mountains and areas along an
west of the Continental Divide. The winds will be breezy
especially in the afternoon while the temperatures continue to be
above the normal as least until Saturday.

Min RH today will be between 18 and 22% in the lowlands and
between 24 and 44% in the mountains. The min RHs on Thursday will
increase 2 to 3% in the lowlands and 4 to 5% in the mountains.
