MDT THIS EVENING FOR WIND AND LOW RELATIVE HUMIDITY FOR FIRE
WEATHER ZONES 483, 484, AND 494...
.BROADCAST DISCUSSION...Hot, dry, and windy conditions will
remain in place across much of Utah through Thursday and beyond.
Some relief from winds is expected Friday through the weekend for
much of the area. However, the potential for critical fire weather
conditions will increase again early next week.
.DISCUSSION...The trough over the Great Basin will lift northward
over the ridge parked over the central United States through this
evening. Conditions will stay seasonably hot and very dry, with
the influence of the trough keep winds breezy across much of the
area. This will result in another day of critical fire weather
conditions, focused over central and southern Utah. As the trough
exits, winds will relax a bit for Friday over the weekend. Still,
winds will be strong enough for critical fire weather conditions
to persist for the mountains of central and southern Utah. Winds
will start to increase again beginning Sunday as another trough
approaches, raising the fire danger once again.
***Thunderstorms imply strong, gusty and erratic winds***
