...DRYING BY MIDWEEK...
.BROADCAST DISCUSSION...Widespread showers and thunderstorms will bring
a high chance of wetting rain today. A drying trend establishes
in the wake of this system, with humidity decreasing through
Thursday alongside increasing southwest winds. Moisture looks to
return late week and into the weekend.
.DISCUSSION...Showers and thunderstorms are continuing to
develop and will only increase in coverage across the entire
state into the evening as a low pressure system crosses the area
in an already moist airmass. This will bring a high chance (50 to
85 percent) of wetting rain, particularly for the higher terrain
of central and southern Utah. Relative humidities will also remain
on the high side, with very few locations falling below 30
percent. Drier air will start to move in from the west on Tuesday,
but this should not be noticeable for much of the area until
Wednesday into Thursday. This is likely to push minimum relative
humidity values into the teens across western Utah Wednesday into
Thursday. In combination with breezy southerly winds due to a low
along the Pacific coast, this could bring area of critical fire
weather conditions. The period of dry weather should be short
lived, however, with guidance increasingly indicating a
substantial surge of tropical moisture into Utah over the weekend.
***Thunderstorms imply strong, gusty and erratic winds***
