Area Forecast Discussion National Weather Service Salt Lake City UT 937 PM MST Tue Jan 21 2020

SYNOPSIS. An upper level trough moving through the northern Rockies will graze northern Utah later tonight through early Wednesday. High pressure aloft will shift east across the Great Basin and bring dry and stable conditions to the area late in the week.

SHORT TERM (Through 00z Saturday). The upper trough currently over the Pacific Northwest will continue on a general eastward track across the northern Rockies later tonight through Wednesday. The upper jet on the back side of this trough will likely stretch the southern end of this feature into far northern Utah for late tonight through Wednesday morning.

Low-level warm advection underneath a mid-level cold pool detached from the main trough will generate sufficient lift to bring an expanding area of light to briefly moderate rain/snow to northern Utah beginning late this evening. The low-level thermal advection will switch to cold advection by early Wednesday morning as the upper trough advance across the northern Rockies.

Looking at short window of deep layer cold advection, dynamic support for lift from the passing trough and a favorably positioned upper jet late tonight/through mid-morning Wednesday. The heaviest precip, mostly now as snow, will occur during this period. The northern valley locations will transition from rain/snow to all snow, though minimal accumulations are expected. Any impacts to the morning commutes will likely remain over the mountain passes, and possibly through the Cache valley, Wasatch mountain valleys, and the Wasatch Front mainly north of SLC.

Some potential exists for a trailing shortwave Wednesday afternoon producing a short burst of snow before slowly building heights ahead of the develop ridge along the west coast brings an end to most, if not all of the snow Wednesday evening.

The aforementioned ridge will continue to slowly amplify as it advances across the Great Basin late in the week. The axis of this ridge should pass through Utah early Friday, with a trailing, and likely weakening shortwave bringing clouds and maybe some light precip back to the area late Friday.

LONG TERM (After 00z Saturday). A very weak shortwave disturbance exiting Utah Saturday evening will yield to a progressive ridge which will cross the area Saturday into Sunday. This ridge will bring generally dry and stable conditions to the area. Although the progressive nature of the pattern will not allow the airmass to become too stagnant, weak flow on Saturday will inhibit mixing, especially in the eastern valleys and Cache Valley.

Southwesterly flow aloft will develop by Sunday afternoon ahead of the next Pacific trough. The initial trough will end up splitting as it comes ashore over California, with a trailing shortwave feature strengthening along the backside of the initial wave as it crosses into the Intermountain region. The initial splitting trough is still expected to produce precipitation near and behind the trough axis Sunday night through Monday morning, as models show the trough tapping into some moisture as it crosses the Pacific. Given the milder Pacific origins of this trough, many lower valleys across western Utah are expected to see rain or a rain/snow mix for the bulk of this storm.

The trailing shortwave trough will cross the area later in the day Monday into Monday night, but its strength is still uncertain at this time. However, given that it will drop in from farther northwest, it will be accompanied by colder air which should drop snow levels to the valleys by Sunday night.

AVIATION. Increasing clouds ahead of the next upper level trough arriving early Wednesday will bring a lowering trend to ceilings after midnight. MVFR conditions could reach the terminal around 08-09Z as the leading edge of the snow moves into the area. Conditions will bounce between MVFR and IFR late tonight through early Wednesday morning during the peak period of snow. Conditions will gradually improve back to VFR conditions during the late morning through the afternoon behind the passing trough.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
