Fire Weather Planning Forecast for Utah

...INCREASINGLY WARM AND DRY, INCREASING MOISTURE LATE WEEK...
.BROADCAST DISCUSSION...A warming and drying trend will continue through
Monday as high pressure builds over the region. Moisture slowly
increases through the remainder of the week with chances for
showers and isolated thunderstorms increasing as well, especially
as we head into the weekend.
.DISCUSSION...High pressure continues to build over the Great Basin
region through Labor Day, bringing warm and dry conditions
alongside largely clear skies across Utah. Through Monday,
temperatures will gradually warm by 2-4 degrees each day, with the
most noteworthy warming expected today. Alongside the warming
temperatures, a drying low level environment will bring decreasing
afternoon humidity through Monday. Minimum humidity for the week
is expected by Monday afternoon as values drop into the 10 to 20
percent range. After Monday, a slow increase in afternoon humidity
(1-2 percent increase per day) is expected through midweek. As
the axis of the upper level ridge begins to shift to the east
through the second half of the week, moisture will increase as
south to southeasterly flow becomes more prevalent. As such, will
see increasing probabilities of afternoon showers and
thunderstorms as we approach the end of the week. Initially,
chances for wetting rains will be quite low (only around 20-30% in
the high terrain of central and southern Utah), increasing the
overall chances for dry lightning though coverage of such will be
limited. As we head into the weekend, a more substantial surge of
moisture finds its way into Utah and chances for wetting rains and
higher afternoon humidity will be present.
***Thunderstorms imply strong, gusty and erratic winds***
