...RED FLAG WARNINGS FOR LIGHTNING AND GUSTY OUTFLOW WINDS FOR MUCH OF
UTAH THURSDAY...
.BROADCAST DISCUSSION...Scattered thunderstorms Thursday afternoon will
be capable of lightning and gusty, erratic outflow winds for much
of Utah. Lightning on dry fuels will bring an increased threat of
new wildfire starts, while gusty outflow winds will also be a hazard
to new or existing wildfires.
.DISCUSSION...High pressure sliding to the south of Utah has brought
warmer conditions, with minimum relative humidity values lowering
into the single digit percent range. To the west, a weak system
has brought locally stronger winds to far northern Utah, where Red
Flag Warnings for wind and low relative humidity are in effect
for far northeast Utah.
High pressure will slide into New Mexico and Colorado Thursday.
That will set up a better flow direction for monsoonal moisture
into Utah. A combination of the enhanced moisture, daytime
warming, and influence from the trough to the west will bring
scattered afternoon showers and thunderstorms for much of Utah.
Still, conditions near the surface will be very dry. That will
result in a dry thunderstorm and gusty, erratic outflow wind
threat, as these showers and thunderstorms will bring minimal
rainfall Thursday. Red Flag Warnings are in effect for much of
Utah Thursday due to lightning and gusty, erratic outflow winds.
Moisture content will increase Friday into the weekend with more
scattered afternoon showers and thunderstorms. These will be
capable of lightning and gusty, erratic outflow winds, but will
also be more likely to produce measurable rainfall.
***Thunderstorms imply strong, gusty and erratic winds***
***All winds are 20 foot, 10-minute averages***
