913 AM MDT Wed Jun 20 2018

.SYNOPSIS...High pressure will bring a warming and drying trend
through Thursday. A series of weak storm systems will bring
somewhat cooler weather to the forecast area Friday through the
upcoming weekend.

&&

.DISCUSSION...
Impacts...
* Very warm today and tomorrow across southern Utah.
* Critical Fire Weather conditions possible Thursday into the
  weekend.

Antecedent Conditions...
Extreme Drought is occurring from south of Provo south to Cedar
City and to the southeast. Severe Drought is occurring surrounding
the Extreme Drought, in areas from Ogden southward and Duchesne
to the Arizona border. Drought conditions scale down to Abnormally
Dry along the Idaho and Wyoming border.

Big Picture...
During the past 5 days, flow across the Pacific has transitioned
from zonal to slightly amplified.

Water Vapor Satellite shows a ridge centered over Baja California,
amplified north into Oregon. A disturbance is off the Oregon and
northern California coast.

Local Observations and Trends...
00Z KSLC RAOB shows a 1.5C subsidence inversion near 640mb with
moderate northwest mid level flow and strong northwest flow aloft.
Precipitable Water values range from 0.20"-0.33" mountains to
0.50"-0.75" northern valleys.

A 1021mb surface anticyclone is located across northwest Wyoming,
with a 1009mb surface cyclone southwest of Nevada. This is
creating a 9mb northeast pressure gradient across the state.

24 hour trends:
* Precipitable Water 0.10"-0.15" higher south central and
  southeast Utah.
* Temperatures are between 5F cooler and 5F warmer
* Dewpoint Depression 5-15F lower (moister) except 5F higher
  (drier) across the north.

Forecast...
Going forecast for tonight is in great shape. Ridging surface and
aloft providing stable conditions. It will continue to warm and
dry today. No significant changes to the forecast.

.PREVIOUS DISCUSSION...
Mid level ridging noted in early morning satellite imagery and
objective analysis across the Great Basin will translate eastward
today, allowing a dry, warm, and stable airmass to overspread the
forecast area. This will allow max temps to climb several degrees
over what was observed Tuesday, particularly across the north.

As this ridge axis continues east tonight into Thursday,
increasing southwesterly flow aloft will advect a very warm
airmass into the region, with max temperatures expected to run 10
or so degrees above climo.

A shortwave trough which is forecast to brush by the area Thursday
night into early Friday will push a mostly dry cold front through
the region, with the only real threat for showers remaining
minimal, and largely confined to the higher terrain north of I-80.
With the passage of the cold front max temperatures should run
close to climo in the north Friday, and a few degrees above in the
south.

Late Friday through Saturday afternoon will largely be a break
between shortwave troughs, with an increase in winds and
temperatures ahead of the next system that is expected to drop in
from the Pacific Northwest. This next trough looks stronger and a
bit more of a direct hit on northern Utah, especially with regards
to low level cold advection and winds associated with the front.
Have increased winds for Saturday afternoon, especially for post-
frontal winds in the northwest desert.

As far as precipitation goes, the best moisture and mid-level
forcing still look to remain northeast of much of the forecast area.
Have maintained some low end POPs across the northeast and the
northern/central mountains, but in general the best activity should
be across Idaho and Wyoming.

As the trough digs into Colorado on Sunday, continued shower
activity is possible across NE Utah and Uinta Co. Wyoming. Sunday
should also yield a noticeable cool-down virtually area-wide, with a
persistent northwest flow in the lower levels.

Temperatures rebound for the beginning of the work week, as the
trough exits the Rockies and ridging builds over much of the
western CONUS. Models hint that just enough mid-level moisture may
linger under the ridge to allow for mountain convection Tuesday
and Wednesday, so have added some low level POPs to typical
locations both afternoons. Otherwise, expect hot and dry weather
to persist through mid-week.

&&

.AVIATION...
VFR conditions are expected to prevail at KSLC through the TAF
period. Southerly winds will become calm about 16Z with northerly
winds becoming established no later than 17Z. The switch back to
southerly winds will happen around 03-04Z this evening.

&&

.FIRE WEATHER...
ERC values are running between the 80th and 96th percentile across
eastern and southern Utah, and rising above the 50th percentile
across northern and west central Utah. Values are steady or rising
except falling along the northern Utah border. 100/1000 hour fuel
moisture has risen just above historical lows across most areas.

A ridge of high pressure will bring dry and stable conditions
across the state today. A system will enter Oregon today and
progress into the northern Rockies tomorrow. This will support a
dry cold front crossing northern and portions of central Utah
tomorrow afternoon. Gusty southwest winds will develop with a
Haines of 6, much warmer temperatures and single digit RH most
locations. Critical fire weather conditions are possible where
fuels are critical.

This boundary will progress to the Arizona border Friday, bringing
a gusty northwest flow. It will be almost as warm, with nearly as
low RH and a Haines of 6 across the south tomorrow. Thus,
critical fire weather conditions may persist.

The boundary lifts northward into southern Utah Saturday with many
variables being similar to Friday there. A gusty westerly wind may
present a continuation of critical fire conditions across southern
Utah Saturday.

The next system dives southeast from Washington Saturday morning
across eastern Utah Saturday night and Sunday. This will bring
another dry cold front through the region.

Temperatures trend warmer through tomorrow, cooler Friday, warmer
Saturday then much cooler Sunday. Tomorrow will be the driest day
with single digit RH across most of the state, rising a bit
Friday across the north, little changed Saturday and a bit higher
Sunday.

No convection expected today, with isolated to scattered showers
and thunderstorms primarily across the northern mountains
Thursday through the weekend.
