Fire Weather Planning Forecast for Utah

...RED FLAG WARNINGS IN EFFECT FOR MUCH OF THE AREA FROM NOON THURSDAY THROUGH 10PM SATURDAY...
.BROADCAST DISCUSSION...Temperatures begin to warm again on Wednesday
alongside a very dry surface environment. A prolonged period of
hot, dry, and windy conditions are expected across the majority of
Utah starting Thursday and persisting through Saturday. Cooler
conditions arrive into northern Utah by Sunday, with potential for
Red Flag conditions to linger across southern and eastern Utah
into Sunday.
.DISCUSSION...Stiff northerly winds in the post-frontal environment
will continue to bring elevated fire weather conditions across
much of Utah through the remainder of Tuesday. Winds are expected
to subside through the overnight hours with improving humidity
recoveries, mainly across the northern half of Utah. For the
southern half of Utah, improvement to humidity recoveries are
still expected, but poor recoveries are still anticipated (15-25
percent). Wednesday will continue to feature very dry afternoon
humidity alongside warming temperatures, however, winds will be
largely terrain driven which will bring lower concerns of critical
fire weather conditions.
By Thursday, an offshore trough will dip farther south and bring
an increase in dry southwesterly flow across the majority of Utah.
Some of the hottest temperatures of the week are also expected by
Thursday, pairing with the already extremely dry afternoon
conditions. There is generally high confidence that winds will
gust in excess of 30 mph across much of Utah by the afternoon
hours. Strong and dry southwesterly flow is expected to remain in
place across Utah from Thursday through at least Saturday,
bringing widespread critical fire weather conditions. As such, a
Red Flag Warning has been issued for numerous fire weather zones
across Utah. A cold front is anticipated to push into the region
by late Saturday/ early Sunday, decreasing the overall threat of
critical fire weather conditions across the northern area.
Depending on the overall speed of this cold front and how far it
progresses into Utah, critical fire weather conditions may persist
across far southern and eastern Utah through Sunday (this is a
generally low confidence forecast).
