Area Forecast Discussion
National Weather Service Salt Lake City UT
840 PM MST Mon Jan 9 2017

.SYNOPSIS...The active weather pattern will continue with another
energetic system moving through mainly northern Utah Tuesday and
Wednesday. One final disturbance will move through the region
Thursday, followed by high pressure heading into the weekend.


.DISCUSSION...A broad and moist trough remains over much of the
western CONUS this evening, with an associated low level cold
front draped across Utah and southwest Wyoming. That front kicked
off convective showers across much of the state earlier today,
producing gusty winds and a quick round of rain and snow. The
steadiest precipitation has shifted into eastern Utah, though some
showers are still lingering across the western half of the state.

Any break tonight will be relatively brief, at least for the
northern portions of the CWA, as the next wave slides along the
Utah/Idaho border through the day Tuesday, followed by a larger
trailing trough on Wednesday. Though this break may not be
significant, will still likely allow the winter storm warning for
the mountains to expire tonight as planned, and then allow the
overnight shift to decide what headlines might be necessary for
the next round or 3 of precipitation.

Updated the forecast earlier this evening to decrease POPs across
the north after the cold front had passed, as well as increase
POPs and add thunder for the south. Otherwise, the forecast looks
good, and no additional updates are currently planned.


.AVIATION...There is a 30 percent chance of ceilings below 7000
feet, or even brief MVFR conditions, due to passing showers
between 04Z and 10Z. Winds could become light and variable or
light westerly at times, but southeasterly winds are expected to
be most prevalent through the night.


UT...Winter Storm Warning until 10 PM MST this evening for UTZ007>010.

WY...Winter Weather Advisory until 10 PM MST this evening for WYZ021.
