Area Forecast Discussion
National Weather Service Salt Lake City UT
901 AM MDT Mon Jul 6 2020

.UPDATE...
Only minor tweaks to the forecast this morning with no real change
to the overall forecast message. Today and tonight will be the
warmest day this week as southerly flow increases ahead of a
shortwave trough that will move through the Northern Rockies.
Temperatures will mainly run about 5 to 10 degrees above normal,
including overnight low temperatures tonight. The only location
forecast to be near a record high temperature today is at
Duchesne.

Near-critical to isolated critical fire weather conditions will
develop this afternoon across portions of southern and central
Utah with no fire weather headlines needed today. However, a
solid Red Flag Warning day remains on track Tuesday with the
increased south to southwesterly winds ahead of the weak cold
front passage. On Wednesday more marginal critical fire weather
conditions possible for southern and eastern portions of Utah.
Latest forecast information supports at least portions of this
Watch may need to be upgraded to a Red Flag Warning later today.

.SYNOPSIS...
A warm and dry southwesterly flow will prevail through much of
the week with fire weather concerns being the main hazard into the
upcoming weekend.

&&

.SHORT TERM (Through 12Z Thursday)...
A broad, low-amplitude ridge extending from the southern plains
through the desert southwest will bring another day of warm and
dry conditions to the forecast area today. An upper level trough
advancing into the Pacific Northwest late tonight will bring about
an increase in southwest flow aloft over the Great Basin Tuesday.
A weak, dry cold front associated with the upper trough will
enter northern Utah by early Tuesday, then settle into central
Utah late in the day.

Dry, but slightly cooler temperatures will trail the front, with
breezy and still quite hot temperatures south of the boundary
Tuesday. The very dry, stable west-southwest flow aloft will
persist across Utah Wednesday. Only looking at minor changes to
temperatures from Tuesday, with warmer temperatures to follow in
the long term forecast period.

.LONG TERM (After 12Z Thursday)...
The story of the long term forecast remains largely unchanged
from the past few days. Hot, dry, and breezy conditions are
expected across a majority of Utah and southwest Wyoming through
the week as we find ourselves under a building ridge with a trough
to the northwest.

A suppressed ridge over the Desert Southwest will begin to build
over the forecast area starting late Thursday into Friday. As this
feature strengthens, the increasing gradient between the ridge and
aforementioned trough will likely allow for modest winds in the low
to mid levels that will translate to breezy conditions at the
surface once daytime mixing is able to establish. This trend is
likely to continue into the weekend as the persistent trough remains
to our northwest and the ridge continues to amplify. Concern for
fire weather conditions lingers as extreme dry conditions remain in
place through the week in combination with these breezy afternoon
winds.

Aside from the potential for extended fire weather concerns,
temperatures across the forecast area are expected to remain near
normal during the middle of the week, with above average
temperatures arriving by the weekend. Southern Utah, in particular,
could see temperatures rise to ~10 degrees above average by the end
of the weekend, while areas in northern Utah will likely see daytime
highs rise to ~5 degrees above average. Chances of precipitation
remain low throughout the extended forecast, however, the
deterministic GFS continues to favor the possibility of a mid-level
moisture surge by the weekend (which may favor high based
convection), while other deterministic guidance favor a dry
forecast. Ensemble guidance seems to favor the latter solution,
thus, have maintained minimal PoPs... but something to keep an eye
on in the coming days.

&&

.AVIATION...
VFR conditions are expected to prevail over the SLC terminal
through the valid TAF period. Southerly winds will remain in place
over the airfield through ~17-19Z before becoming northerly
through 03Z before returning to the south. Winds tonight will
increase from south with a chance of gusts from the south over 20
knots by Tuesday morning.

&&

.FIRE WEATHER...
A developing upper level trough over the Pacific Northwest
combined with high pressure centered over the southern Rockies
will lead to continued low humidity and increasing southerly winds
on Tuesday. Widespread critical fire weather conditions are
expected across southern and central Utah on Tuesday.

A weak cold front will slip south through northern Utah Tuesday,
then stall over central Utah by Tuesday night. Behind this front
slightly lower temperatures with still low RH values are expected.
South of this front humidity values will remain quite low with
enough supporting winds aloft to bring a chance for critical
or near-critical fire weather conditions Wednesday. Will leave
the current Fire Weather Watch in place for now as some
uncertainty remains as to whether winds will be strong enough
over a wide enough area to justify a warning.

A gradual strengthening of the southern Rockies high late in
the week will further boost temperatures and keep humidity values
low. Only looking at fair to poor recoveries at night during the
latter half of the week and into the weekend. Winds at this point
look to remain below level to create critical fire weather conditions.
The only area of concern at this point would be with the southwest
and west-central zones where winds could briefly reach critical
levels by Friday and on into the weekend.

the upcoming weekend. These winds coupled with a very dry airmass
and dry fuels will bring the potential for critical fire weather
conditions beginning Tuesday, and continuing through the weekend.
