...New AVIATION...

.SYNOPSIS...
Issued at 1255 PM MDT Mon Jun 17 2024

Hot and dry weather will transition into cooler and wetter weather
later in the week. A tropical system from the gulf of mexico will
bring moisture which will give the region a chance of drizzle by
the end of the week. Lingering moisture will allow for a chance of
thunderstorms over the weekend and into early next week.

.DISCUSSION...
Issued at 1255 PM MDT Mon Jun 17 2024

Currently, there is a trough situated in the Pacific Northwest,
which is moving eastward. This trough will stay far north of the
region, but will allow for a lowering of geopotential heights.
This lowering of heights will keep temperatures away from record
levels. However, southwesterly flow will allow warm air advection
(WAA) to continue and highs will be hot in the low 100s. Dry
weather is expected as most moisture remains to our east. Breezy
winds will remain. These hot, dry, and breezy conditions will
continue into the middle of the week.

An inverted trough will be pushed onshore from the Gulf of Mexico
in south-eastern Texas on Wednesday due to a large area of high
pressure in the southern US. This inverted trough will bring
onshore a large amount of moisture. The high pressure in the
southern US will steer this moisture plume to the region. Higher
elevations will start to be impacted late Wednesday with a chance
of thunderstorms. The lowlands will start experiencing effects on
Thursday. Winds will become southeasterly and PWATs will soar to
1.0 to 1.3 in across the region. Soundings show that the moisture
layer will be quite shallow with cloud ceilings as low as 1500ft
in the lowlands. A subsidence inversion will prevent convective
storms from forming through Friday, so rainfall will be stratiform
in nature. Cloudy conditions with drizzle are expected for
Thursday and Friday. QPFs will be low at less than 0.02 in for
the lowlands. Higher elevations will see heavier rain with
QPFs of up to 0.2 in. Temperatures will cool into the low 90s in
the lowlands due to extensive cloud cover.

The high over the southern US will set up
over the region over the weekend. High temperatures will warm
back up into the low 100s and winds will become light and variable.
This high pressure will trap lingering moisture in the region and
allow for convective storms to form. This chance of thunderstorms
will remain into early next week with the higher elevations having
a greater chance.

VFR conditions through the period with SKC. Smoke from the
Sacramento Mtns could cause slightly lowered visibilities

diminishing after 03Z to west/northwest AOB 8 knots.

.FIRE WEATHER...
Issued at 1255 PM MDT Mon Jun 17 2024

Elevated fire danger continues this evening with southwest winds
15 to 20 mph and min RH 5-12%. Winds peaking in the late afternoon
with Excellent smoke ventilation and transport to the NE. Winds
will be a bit lighter on Tuesday with similar conditions
otherwise.

Pattern change expected late this week as moisture arrives from
the southeast increasing humidity, rain chances, and cloud
coverage Thursday through Saturday. Temperatures will be much
cooler those days under ESE flows and Good ventilation. Scattered
showers and thunderstorms can be expected each afternoon, with
gusty and erratic outflow winds and possible new lightning starts.
Monsoon season well underway next week with continued daily storm
chances and seasonably hot temperatures.
