...NEAR CRITICAL FIRE WEATHER CONDITIONS WESTERN UINTA BASIN TODAY...
.BROADCAST DISCUSSION...
Near critical fire weather conditions in the western Uinta Basin
this afternoon. A passing system will bring a period of isolated
showers and increased cloud cover late Thursday through Friday
morning. Southwesterly winds and gusts will trend upwards through
Saturday ahead of a strong largely dry cold front which will pass
through the region on Sunday. Moisture increases in southern,
eastern Utah through the weekend.
.DISCUSSION...
Increased westerly flow across southwest Wyoming this afternoon
will influence some briefly stronger westerly winds in the western
Uinta Basin this afternoon through early evening. Near-critical
to localized critical fire weather conditions will develop over the
far western Uinta Basin as wind gusts near 25 mph with RH values
around and just below 15%. Expect these conditions to be short-
lived and relatively localized.
Tonight a weakening boundary will push through northern Utah,
which will result in an increase in cloud cover and isolated to
widely scattered showers or virga. No wetting rains are expected
from this passing features. This will however set the stage for
locally heavy rainfall potential by Friday afternoon across
southern Utah near the Upper Escalante, Capitol Reef and the Henry
Mountains where some monsoon moisture runs into the decaying
boundary.
Southwesterly winds will increase across Western Utah on Saturday
as an upstream trough moves into the Pacific Northwest and the
ridge re-estabilishes over New Mexico. This will result in windy
conditions across western Utah Saturday through late Saturday
night and early Sunday morning, however humidity values will
remain borderline for fire weather conditions (15-20% min RH
values), combined with current fuels conditions reported as only
"approaching critical", the overall threat of critical fire
weather conditions is not particularly elevated despite the
potential for wind gusts exceeding 45 mph (50% chance) across
western Utah.
Models continue to then support this system slipping by the
region, pushing a cold front southward through Utah most likely
some time Sunday, though of note some models have slowed more in
the Sunday night to early Monday time range. Models have however
maintained consensus in this frontal passage being overwhelmingly
dry, with the best low end chances of precipitation noted across
portions of southern to eastern Utah.
