WIND AND LOW RELATIVE HUMIDITY FOR FIRE WEATHER ZONES 489, 493,
494, 496, AND 498...
.BROADCAST DISCUSSION...A dry cold front will remain stalled over
central Utah into Saturday. To the south and east of this front,
a very dry and unstable airmass combined with gusty southwest
winds will bring critical fire weather conditions to southeast
Utah through Saturday. Meanwhile, a cooler and more stable airmass
will settle across northern Utah.
.DISCUSSION...A stalled cold front extends from near Milford to
the eastern Uintas this afternoon and will move little through
Saturday. Areas behind this boundary will see a stable and
relative cool airmass, while areas ahead of the boundary see
pockets of critical fire weather conditions due to gusty
southwest winds. The front will weaken and shift slowly southward
Saturday into Sunday as high pressure rebuilds over the area.
Southeast Utah will see another day of critical fire weather
conditions on Saturday, but with the ridge overhead on Sunday,
winds will be much weaker, lowering the fire danger somewhat. The
light winds will continue through the middle of next week with
continued dry conditions and a steady warming trend.
***Thunderstorms imply strong, gusty and erratic winds***
***All winds are 20 foot, 10-minute averages***
