...MOISTURE TO CONTINUE TO INCREASE...
.BROADCAST DISCUSSION...A monsoonal surge will bring increasing
quantities of moisture late this week into next week. While
initial activity may be somewhat dry in nature, it will shift and
continue to become wetter with more widespread coverage. With the
moisture surge and associated precipitation, temperatures will
trend downward from the weekend into next week.
.DISCUSSION...Expansive high pressure situated near the Four Corners
region is continuing to result in very mild temperatures. Small
quantities of moisture are starting to work in around this high
pressure ridge, resulting in some high based showers across
western Utah. Given the higher based nature, these showers will
primarily carry a threat of gusty and erratic outflow winds.
Moisture will continue to increase Thursday onward as a more
marked monsoonal surge begins in earnest. Afternoon showers and
thunderstorms will start to become more widespread, wetter in
nature, and associated humidity values trend upwards. Coverage
will especially increase in coverage Sunday into early next week
as the moisture becomes maximized. This expansion to precipitation
will also result in a more noted trend downward to temperatures
and trend upward in humidity.
***Thunderstorms imply strong, gusty and erratic winds***
***All winds are 20 foot, 10-minute averages***
