Area Forecast Discussion National Weather Service Salt Lake City UT 502 AM MST Thu Dec 12 2019

SYNOPSIS. The first in a series of fast moving weather disturbances will cross northern Utah this morning. Periods of rain and snow will continue across northern Utah and southwest Wyoming through Friday night, then shift south into southern and central Utah over the weekend.

SHORT TERM (Through 00Z Monday). A near zonal mid-latitude pattern over the western CONUS through the eastern Pacific will bring a series of fast moving shortwaves across northern Utah/southwest Wyoming through Friday night. Ridging setting up over the eastern Pacific will drive a deepening shortwave southeast into the Great Basin this weekend. This shortwave will bring organized precip to southern Utah and colder temperatures to the north during the weekend.

The series of fast moving shortwaves ushered in by a 140+ knot jet will be tapping into the atmospheric river plunging into the central west coast. This exceptionally moist air mass working with the lift generated by these fast moving dynamic features will produce a prolonged, though not continuous, period of precip across northern Utah/southwest Wyoming through Friday night/early Saturday. Significant snowfalls are expected across the northern mountains, with the Wasatch range taking the brunt of the heavy snow.

The northern valleys will also receive substantial amounts of precip, though the precip-type will vary depending on the intensity of the precip and how far south the colder air aloft penetrates into the area. At this time it appears that the areas close to the Idaho border along with the Wasatch mountain valleys will remain cold enough to support snow, with brief periods of rain and/or snow through this evening. Farther south sufficient mixing along with marginally cold temps aloft point towards more rain than snow, with brief periods snow confined mainly to the bench/foothill areas.

Amplification of the pattern across the eastern Pacific/western CONUS this weekend will drive a strengthening shortwave southeast into the Great Basin for Saturday night/Sunday. Fairly strong warm advection will develop ahead of the trough across northern Utah Friday night, followed by a quick transition to low-level cold advection developing just ahead of the mid-level trough on Saturday. The resultant low-level baroclinic zone will sweep south across the state and reach southern Utah early Saturday evening.

This near 700mb thermal boundary will set up across the far south Saturday night. This boundary will become the focus of low level forcing by the time the mid-level trough arrives late Saturday night. Anticipating a band of moderate to occasionally heavy precip forming along the low-level thermal boundary as deep lift increases through Sunday morning. This precip will begin to shift south and east of the state as the mid-level trough approaches the four corners region late in the day.

LONG TERM (After 00Z Monday). In the wake of a departing trough, a fairly benign weather pattern looks to take hold through much of the long term period, as a mean mid level ridge develops across the region. Some guidance does suggest a weak shortwave will translate through the mean mid level ridge position late in the period, and as a result maintained some slight chance PoPs in the higher terrain although these features typically struggle to produce much if any sensible weather. Otherwise leaned toward a blend of model guidance through the long term period.

AVIATION. Southerly winds are expected to prevail at KSLC through the TAF period. CIGS are expected to gradually lower into the MVFR category late this morning into the afternoon hours with passing rain showers. There is a 20 percent chance for IFR conditions after 19Z.

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.
