Area Forecast Discussion National Weather Service Salt Lake City UT 918 PM MST Sun Feb 23 2020
SYNOPSIS. A disturbance in NW flow aloft will bring a cold front across northern Utah tonight and through remainder of the state by Monday afternoon. High pressure will build into the region Tuesday and prevail through the rest of the week.
DISCUSSION. The latest satellite water vapor imagery shows the next upstream trough currently over the PacNW states and western Idaho. The associated cold front is currently southeast of Boise and will reach far northwest Utah shortly. In the meantime, Utah remains under partly cloudy to mostly clear skies, with a patch of fog and low stratus continuing to linger near Milford.
The cold front will sweep quickly through northern Utah late tonight and push into southern Utah tomorrow morning. A brief period of gusty northwest winds will accompany the cold front. However, the storm will not be very productive precipitation-wise. The 500mb cold pool and vort max will just graze far northern Utah and southwest Wyoming, and moisture will be lacking. The only thing going for this storm will be the strength of the low-level cold front and 700mb baroclinicity. Not very enthusiastic regarding more than a dusting of snow for most of the northern Utah valleys, and the northern mountains should see just minor accumulations. The front will outrun all of its upper support once it gets to southern Utah so precipitation is not expected there.
A cold northerly flow aloft will settle into the area through Tuesday before high pressure builds inland and the airmass warms through the rest of the week.
No updates this evening.
AVIATION. The SLC terminal will see VFR conditions through the rest of the evening with southeast winds. A cold front will turn winds back to the northwest beginning near 07z. Winds may exceed 26kt/30mph briefly just behind the front. The front will also bring CIGs below 7kft, and perhaps a brief period of MVFR conditions or lower in snow. Any snow that develops overnight will most likely accumulate 1/2 inch or less on untreated surfaces.

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 numerous 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.
