Fire Weather Planning Forecast for Utah
National Weather Service Salt Lake City UT
203 PM MDT Fri Sep 11 2026
...MOISTURE FOR SOUTHERN AND EASTERN UTAH, COLD FRONT SUNDAY NIGHT...
.BROADCAST DISCUSSION...Isolated showers and thunderstorms are expected
each afternoon through Sunday across southern and eastern Utah
while the northern area remains dry. A cold front moves through
the northern third of Utah Sunday evening, though little change in
moisture is expected. A warming trend reestablishes through next
week.
Isolated showers and thunderstorms will
be possible Friday and Saturday, primarily across southern and
eastern Utah during the daytime. Generally southwesterly winds
and gusts will increase through the weekend ahead of the next
system. A largely dry cold front will then pass in the Sunday
to Monday time frame, bringing cooler weather behind it.
.DISCUSSION...Moisture increases across the southern and eastern
portions of Utah through the upcoming weekend, bringing potential
for shower and thunderstorm development over the high terrain in
these areas, particularly today and Sunday. While moisture will be
increased across the south and east, the northern and western
portions of Utah will remain largely dry with minimum relative
humidity continuing to fall to near 15% (or slightly below) each
afternoon. Breezy southwest winds ahead of a late weekend cold
front will pair with the borderline critically dry conditions in
western Utah, creating near-critical to isolated critical fire
weather conditions on Saturday and Sunday afternoon.
A cold front will graze across northern Utah Sunday evening
through Monday morning, bringing shifting winds across the
northern third of the area. Localized strong winds may be possible
on the lee sides of mountain ranges in northwest Utah during the
overnight hours. In the wake of the cold front, much cooler
temperatures will spread over the area, though humidity will not
see much improvement. Through the remainder of the week, southerly
return flow will bring an increase in temperatures across the
northern area while southern Utah will see little change in the
atmospheric moisture content. As it stands, the greatest concern
for fire weather conditions over the next 7 days will exist across
western and northern Utah while conditions remain moderated in
the southern and eastern area.
