...RED FLAG WARNING REMAINS IN EFFECT UNTIL 9 PM MDT THIS EVENING
FOR WIND AND LOW RELATIVE HUMIDITY FOR FIRE WEATHER ZONES 482,
483, 484, 488, 489, 493, 494, 496 AND 498...
.BROADCAST DISCUSSION...A dry cold front continues to cross
southern Utah this afternoon. Gusty winds continue both pre- and
post-frontal this afternoon, with critically low humidities across
portions of eastern and southern Utah. Downslope areas of central
and southern Utah will see localized critical fire weather
conditions Sunday. High-based thunderstorms will bring the threat
of lightning Wednesday into Thursday.
.DISCUSSION...A cold front is crossing southern Utah this afternoon.
Gusty winds both ahead of and behind this cold front will combine
with very low humidities to bring critical fire weather
conditions to portions of southern and eastern Utah. While winds
will be lighter as high pressure begins to shift into the region
Sunday, localized critical fire weather conditions will be
possible in downslope areas of central and southern Utah.
A warming trend will be associated with high pressure building
into the region. Very dry conditions will continue with poor
overnight recoveries, especially south of I-80 through Wednesday.
Mid-level moisture will increase as high pressure shifts east of
the region Wednesday. It will take several days to moisten the
lower levels with any thunderstorms, so initially both Wednesday
and Thursday, thunderstorms will be high based and represent a
threat of new starts associated with lightning after a dry period,
especially across southern Utah.
***Thunderstorms imply strong, gusty and erratic winds***
***All winds are 20 foot, 10-minute averages***
