Area Forecast Discussion
National Weather Service Salt Lake City UT
911 PM MST Sat Nov 18 2017

.SYNOPSIS...High pressure aloft will remain over the region
through the balance of the weekend. A weak weather disturbance
will graze northern Utah on Monday, followed by even stronger
high pressure aloft returning midweek.


.DISCUSSION...The low amplitude upper ridge across most of the
western CONUS will maintain a dry and mild near zonal flow across
this forecast area through early Monday. Building heights along
the west coast beginning late Sunday night will take a shortwave
over the Pacific Northwest and turn it to east-southeast into the
northern Great Basin Monday.

The southern end of this shortwave will graze far northern Utah
Monday afternoon. Lift generated by this feature, both dynamic and
thermally generated lift, look to be sufficient to generate light
precip across the far north through early evening. Steadily
building heights across the interior west beginning Monday night
will push any subsequent precip north of the state and bring much
above normal temps back to the entire area through end of the week.


.AVIATION...No significant weather concerns at the SLC terminal
through the valid TAF period. Light southeasterly winds will
prevail for the rest of the night.
