.SHORT TERM /THROUGH SUNDAY NIGHT/...
Issued at 252 PM MDT Sat Jul 6 2024

The weather pattern features a ridge of high pressure over the
West Coast and a long wave trough over the center of the U.S.
this afternoon. Consequently, dry air will continue to move
over the region tonight resulting in few clouds and no chance
for precipitation. On Sunday, a short wave mid-level trough
moving southeastward across the northern Rockies and northern
High Plains brushes Colorado`s northern and central Continental
Divide mountains bringing a chance for isolated to scattered
showers and thunderstorms for those areas during the afternoon
and evening. In addition, this disturbance will bring breezy
afternoon/evening winds with the strongest winds across the
south. Afternoon highs are expected to be near normal with lows
tonight and Sunday night just a bit below seasonal norms.

.LONG TERM /MONDAY THROUGH SATURDAY/...
Issued at 252 PM MDT Sat Jul 6 2024

The surface high currently stationed off the California coast
will slowly build west towards the forecast area next week. As
it does temperatures will warm above normal. Valley locations
receive the burnt of the heat with afternoon temperatures rising
to 5-10 degrees warmer than typically seen in the first half of
July. Precipitation chances will remain hard to come by as
well. We`ve been monitoring the potential for moisture advection
into the area this coming week, but recent trends do not look
favorable. The GEFS and ECMWF ensembles do show PWATs increasing
by Tuesday into Wednesday, but even so they are projected to
remain below normal for this time of year. A few showers and
storms may form each afternoon in the San Juans come mid-week
and beyond (20-40% chance), but beyond that most locations will
likely remain dry.

.AVIATION /00Z TAFS THROUGH 00Z SUNDAY/...
Issued at 517 PM MDT Sat Jul 6 2024

The stronger, gusty winds we`ve seen through the afternoon at
many locations will continue through the next 3 or so hours,
before dropping after sunset. Winds after this point will either
start to follow typical terrain driven drainage patterns, or
else become light and variable. Skies are expected to remain
clear through the period. Stronger, gusty winds will return
again tomorrow afternoon. VFR conditions will prevail for the
next 24 hours.

.FIRE WEATHER...
Issued at 252 PM MDT Sat Jul 6 2024

Red Flag Warnings continue through 9 PM this evening for
northeast and east-central Utah and northwest Colorado when
winds decrease and relative humidity begins to recover.

On Sunday, breezy conditions are expected to redevelop during
the afternoon and continue into the evening. However, the
stronger winds shift south of the I-70 corridor. Based on winds
and low relative humidity, issued a Fire Weather Watch for
southeast Utah and a portion of southwest Colorado. NFDRS was
utilized in lieu of Colorado Fuels Status to pin down fire
danger for southwest Colorado.
