SYNOPSIS. A Pacific storm system will exit the region early Monday. High pressure aloft will return to the region early in the upcoming week, with another system possible by midweek.
SHORT TERM (Through 00Z Friday). Early morning satellite imagery and objective analysis depict a positively tilted trough exiting the region, while upstream a high amplitude mid level ridge is noted along the Pacific Coast. This is allowing for a deep layer northwesterly flow aloft across the forecast area. With cold air aloft still in place a few orographically induced snow showers continue along and east of the Wasatch crest, while areas of stratus are noted banked along and west of the terrain in GOES nighttime microphysics imagery. Given that the snow has generally tapered to a few lingering showers have gone ahead and dropped the going Winter Weather Advisory. Otherwise anticipate stratus to hang on along the terrain for much of the day and have maintained this idea in the sky cover forecast.
The upstream ridge will gradually translate eastward through Tuesday allowing temperatures aloft to warm. This will allow valley inversions to redevelop across much of the forecast area. A weakening and moisture starved shortwave trough is forecast to cross the area Wednesday bringing an increase in cloud cover and some cooling loft (which may help disperse or at least weaken any inversions which develop), but little if any chance for precipitation.
In the wake of this wave, a strong Pacific jet is forecast to spread inland and nose into northern Utah by Thursday. Warm air/moisture advection associated with this feature will allow for valley rain/mountain snow across far northern Utah by Thursday afternoon.
LONG TERM (After 00Z Friday). Precipitation is expected to increase over northern Utah and southwest Wyoming Thursday night into Friday as shortwave energy moves over the top of the ridge centered off the southern California coast. As it does so, the airmass over the area is expected to gradually cool in the moist west to northwest flow.
A temporary downward trend in precip coverage is possible Friday night into early Saturday as the initial shortwave energy moves away from the area. However, deterministic guidance and associated ensembles continue to be in good agreement that the main system and associated cold front will finally break down the ridge and move over the forecast area Saturday afternoon into Sunday. In additional to having the potential to bring significant precipitation to parts of the forecast area, the system should be strong enough to mix out the air associated with any valley inversions that may have developed. High pressure is expected to return by day seven, with high temperatures having cooled to at least 10F below seasonal normals.
AVIATION. VFR conditions are expected throughout the day at the SLC terminal, though cigs should be at or below 6000 feet AGL before rising above that value between 12Z and 15Z. Northwest winds will continue throughout the daylight hours.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
