.KEY MESSAGES...

- Increasing winds will bring the potential of critical fire
  weather conditions to southwest Utah on Thursday. Critical fire
  weather conditions will become more widespread for the weekend
  as winds strengthen further.

- The threat of heat-related illness will increase Wednesday
  through at least Saturday across most Utah valleys, especially
  for those who are sensitive to the heat, those without adequate
  cooling or hydration, and those with chronic health conditions.

.DISCUSSION...Utah and southwest Wyoming are under a dry west to
southwest flow aloft in weak ridging between a weak low off the
Pacific coast and a trough moving north of the area. This will
suppress convection and allow the warming trend to continue, with
maxes averaging 5-7F above seasonal normals across the area.

Conditions will stay dry through Saturday, with the warming trend
accelerating as the troughs move away from the area and a broad
Pacific high builds in. Highs will peak on Saturday, with maxes up
to 15F above seasonal normals, most noticeable over northern
portions of the area. The increasing temperatures will bring the
HeatRisk into the moderate category, so sensitive groups should
see some increase in heat-related impacts.

Winds will increase modestly over southern Utah by Thursday with
one last trough moving north of the area, which could result in
some critical fire weather conditions. After a decrease in winds
Friday, they are expected to pick up in earnest over the weekend
as a Pacific Northwest trough moves onshore, resulting in more
widespread critical fire weather conditions. Confidence is
increasing in that system bringing a mostly dry front through the
area on Sunday, with temperatures then rebounding for the upcoming
work week.

&&

.AVIATION...VFR conditions will persist for the KSLC terminal
through the period. Dry and stable conditions with a few high clouds
will continue. Winds will remain light and diurnally driven.

.REST OF UTAH AND SOUTHWEST WYOMING...VFR conditions will persist for
the entire airspace. Dry and stable conditions with a few high
clouds will continue with light and diurnally driven winds.

&&

.FIRE WEATHER...Very dry conditions will continue for the next
several days, particularly over southern Utah. Thus, the potential
for critical fire weather conditions will be determined by changes
in wind speed. Winds look to pick up Thursday, particularly over
southern Utah where some gusts up to 35 mph look likely.
Therefore, have issued a Fire Weather Watch for the southeastern
zones. Winds are expected to decrease a bit Friday, but locally
critical fire weather conditions can still be expected. As a
stronger storm system approaching the Pacific Northwest coast over
the weekend winds should increase more substantially, and there is
increasing confidence in widespread critical fire weather
conditions where fuels are dry for Saturday and Sunday, and likely
beyond.

     evening for UTZ496-498.
