the area today. High pressure aloft will quickly follow for the
upcoming weekend bringing warm and dry conditions areawide. The
next Pacific storm system will cross the region Monday night
Discussion...precipitation has died down across most valley
locations across the forecast area this morning in the wake of a
boundary that exited the state overnight. Some showers remain
south of the Great Salt Lake...with rain falling in the Tooele
Valley and extreme western portions of Salt Lake County. These
showers will decrease through the day as cold air aloft moves to
the east of the forecast area. Periodic snow showers will continue
across the higher terrain of central and northern Utah through
this afternoon...though with diminishing upper
support...accumulations will be light. Updated the forecast to
lower probability of precipitation across southeastern Utah this morning...and the rest of
the forecast area this afternoon.
As the low pressure system that brought widespread precipitation
to the state moves eastward...the surface pressure gradient and
700mb cold air advection will be favorable for the development of
downslope winds across Castle country this and prone portions of
Washington County this afternoon. At this time wind speeds are
forecast to remain below advisory levels.
High pressure will build into the forecast area through Sunday
bringing warming...drying conditions.
Aviation...VFR conditions are expected through the taf period. Ceilings
will remain below 6000 feet above ground level through about 18z then become
scattered and rise. North winds will prevail today through the
evening before switching to southeast after about 08z.
