...RED FLAG WARNINGS THROUGH THIS EVENING FOR STRONG SOUTHWEST
WINDS AND VERY LOW RELATIVE HUMIDITY ACROSS MOST OF CENTRAL,
SOUTHERN AND EASTERN UTAH...
.BROADCAST DISCUSSION...Strong southwesterly winds and very low
relative humidity will drive critical fire weather conditions
across central and southern Utah into Saturday evening.
Additionally, a strong cold front will begin to sweep through Utah
Saturday evening into the overnight hours, leading to a wind
shift and much cooler conditions.
.DISCUSSION...A cold frontal boundary remains draped from roughly
west central Utah northeastward into southwest Wyoming this
afternoon. At areas ahead of/south of this front, strong
southwesterly winds and very low relative humidity values continue
to drive widespread critical fire weather conditions. A
reinforcing cold front driven by an anomalously cold airmass will
begin to sweep southward through Utah by Saturday evening,
continuing southward into the overnight hours. The passage of this
front will be marked with a sharp wind shift favoring the
northwest, and the intrusion of the colder airmass. While
overnight recoveries will be briefly improved tonight, the lack of
moisture with this system will result in very low relative
humidity values once again Sunday. Winds Sunday will favor a more
westerly direction with more modest gusts up to 25 mph or so,
leading to more isolated pockets of elevated fire weather
conditions. The highest chance of near critical conditions is
noted across southern and eastern Utah.
Through the upcoming week a gradual warming trend will take place
and the dry conditions will be maintained. Day to day winds and
gusts appear more modest, but with some gusts in the 20-30 mph
and a continuation of very low relative humidity values, areas
of elevated to near critical fire weather conditions are
expected.
***Thunderstorms imply strong, gusty and erratic winds***
