...FLASH FLOOD WARNING FOR THE FORSYTH BURN SCAR REMAINS IN EFFECT 
UNTIL 245 PM MDT THIS AFTERNOON FOR CENTRAL WASHINGTON COUNTY...

At 127 PM MDT, A USGS gage camera on the Santa Clara River near Pine 
Valley has shown several pulses of 1 to 2 foot rises on the river. 
Between 0.5 and 1 inch of rain has fallen. Flash flooding is already 
occurring.

Excessive rainfall over the burn scar has resulted in several pulses 
of muddy flow with some light woody debris moving through the Santa 
Clara River. Additional impacts are expected within the Pine Valley 
Recreation Area.

HAZARD...Life threatening flash flooding. Thunderstorms producing
         flash flooding in and around the Forsyth Burn Scar.

SOURCE...USGS Camera.

IMPACT...Life threatening flash flooding of areas in and around
         the Forsyth Burn Scar.

Some locations that will experience flash flooding include...
  Pine Valley, the Santa Clara River from its headwaters downstream 
  to just below Baker Reservoir, Pine Valley Recreation Area.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Move to higher ground now. Act quickly to protect your life.

Stay away or be swept away. River banks and culverts can become 
unstable and unsafe.

Area Forecast Discussion
National Weather Service Salt Lake City UT
608 AM MDT Wed Jul 29 2026

.KEY MESSAGES, Issued 1009 PM MDT Tue Jul 28 2026...

- Monsoon moisture will increase and spread northward for
  Wednesday, bringing a heightened threat of flash flooding,
  before building high pressure brings a drying trend Thursday
  through the weekend.

- There is a high chance that temperatures will become extremely
  hot by the weekend as the ridge continues to build, bring the
  potential for an increase in heat related illness.

&&

.DISCUSSION, Issued 1009 PM MDT Tue Jul 28 2026...
A broad ridge is centered over the central United
States this evening, allowing for a southerly flow to develop over
Utah and southwest Wyoming. The airmass over the area has remained
relatively moist, with satellite derived PW values in the 0.8 to
1.0 range across much of the area, highest over southern Utah.
Earlier showers and storms over southern Utah are decreasing in
coverage at this time. However, a series of weak shortwaves moving
north across Utah overnight will allow for some showers to
continue into the morning.

The southerly flow will allow moisture over the area to increase
and spread northward through tomorrow afternoon, with PW values of
an inch or more expected to spread over the vast majority of the
forecast area. Combined with the supplemental instability from the
shortwaves, this will bring another round of showers and
thunderstorms, and any storms that develop will be capable of
producing heavy rain that could lead to flash flooding. The
showers and associated cloud cover area expected to keep high
temperatures near to just below seasonal normals during the day.

Beginning Thursday, the broad ridge is expected to re-orient
itself over the west, with the center moving directly over Utah
for the weekend. This will add a westerly component to the flow
aloft that will draw a drier airmass into the area, decreasing the
threat of convection. As the ridge strengthens, temperatures will
become increasingly hot, peaking on Saturday with 700mb
temperatures expected to be in the lower 20s Celsius across the
entire area. This will result very hot temperatures that will
increase the risk of heat related illness, particularly for valley
locations. Some uncertainty remains with regard to how high the
HeatRisk will get on Friday, with Thursday nights lows potentially
getting low enough to keep the HeatRisk in the orange (moderate)
range for much of northern Utah during the day. For Saturday and
Sunday, confidence is higher than usual in the potential for very
hot maximum temperatures, but there remains a good amount of
spread in the ensembles with regard to low temperatures and
therefore how much overnight relief the area, northern Utah
in particular, will see. Therefore, have decided to hold off on
an Extreme Heat Watch at this time due to uncertainty about the
length of time of the event.

By early next week, the ridge is expected to weaken a bit and
shift south as a Pacific Northwest trough moves over the top of
it. This would provide some relief from the heat, at least for
northern portions of the area, though there remains a good amount
of spread in the guidance with regard to how much the trough will
act to weaken the ridge and therefore how much of a drop in
temperatures there might be. It does seem likely, however, that
the very hot weather will continue for at least southeast Utah.

.AVIATION...
KSLC...There is a 30% chance for showers to impact the terminal with
variable winds between 12-15z. Otherwise, showers continue along the
high terrain east of the terminal through the evening. Showers and
thunderstorms moving in from the west after 00z have a 30% chance to
bring gusty and erratic outflow winds to 40-45 kts through around
04z. VIS reductions are also possible with storms this evening, with
potential to result in brief MVFR conditions. Convective activity
tapers thereafter, with generally light southeasterly winds
prevailing overnight.

REST OF UTAH AND SOUTHWEST WYOMING...Showers across central Utah
will continue spreading northeast through early this afternoon.
Additional development of showers and thunderstorms are expected
across southern Utah this afternoon and evening, moving into
northern Utah and southwest Wyoming later in the evening. Storms
today will be capable of producing gusty and erratic outflow winds
to 45 kts as well as brief heavy rainfall that could produce brief
VIS reductions to MVFR. Conditions quickly dry out areawide after
06z, with generally light terrain driven winds prevailing overnight.

&&

.FIRE WEATHER, Issued 214 AM MDT Wed Jul 29 2026...
Scattered showers and thunderstorms are expected to
develop early this morning across central Utah, spreading
northward through late morning. Another round of showers and
thunderstorms develops early this afternoon across southern Utah,
with coverage becoming more widespread across the state through
the remainder of the afternoon. Expect activity to taper off late
tonight. Storms today will be capable of producing locally heavy
rainfall, lightning, and gusty and erratic outflow winds upwards
of 40 to 50 mph. Monsoonal moisture is flushed out of the state
quickly on Thursday as high pressure strengthens across the
western US, introducing a much drier airmass through at least
early next week. This pattern will also result in temperatures
trending 5 to 10 degrees warmer this weekend. Given the
combination of unseasonable heat and relative humidity values
reaching critical values statewide by Friday, heightened fire
weather concerns will exist through the weekend especially across
the western half of the state.
