Area Forecast Discussion
National Weather Service Salt Lake City UT
929 PM MDT MON JUL 25 2016

.SYNOPSIS...An upper level ridge over the Great Basin will result
in continued hot conditions across the area. Remnant moisture will
allow isolated storms to develop across central and southern Utah
Tuesday before a more westerly flow aloft dries the region out by
midweek.

&&

.DISCUSSION...A mid level ridge axis extends from the southern
rockies westward into the southern Great Basin this evening, while
a weak shortwave is noted crossing the northern Great Basin of NV.
Just enough mid level moisture coupled with a very deeply mixed
boundary layer allowed for isolated convection across portions of
northern UT today, with somewhat better coverage across the south.
With the loss of daytime heating this convection has been on the
downward trend over the past couple of hours, and have updated the
forecast accordingly.


&&

.AVIATION...Southerly winds with VFR conditions will prevail at
KSLC overnight through Tuesday morning.

&&

.FIRE WEATHER...The southwest flow over the district today has
spread moisture north to about I-80 and isolated to scattered
showers and thunderstorms will continue south of there well into
this evening. Drier westerly flow will begin to spread across
western Utah on Tuesday with enough moisture remaining over the
mountains and east for another round of isolated afternoon
thunderstorms. Hot and dry conditions over the north and west
Tuesday will expand across the entire district on Wednesday as the
drier west to northwest flow spreads into the south and east. It
appears a little moisture will start to move back into
southwestern Utah on Thursday then increase through the weekend
bringing a renewed threat of afternoon thunderstorms. This next
round of thunderstorms looks to be on the dry side at least for
the first part of the weekend with a chance of dry lightning.

&&

.SLC Watches/Warnings/Advisories...
UT...None.
WY...None.
