Area Forecast Discussion National Weather Service Salt Lake City UT 356 PM MDT Fri Apr 3 2020

SYNOPSIS. A warming and drying trend is expected through Saturday. Somewhat unsettled conditions will develop Sunday and continue into next week as a slow moving system crosses the region.

SHORT TERM (Through 12Z Monday). A warming trend can be expected through Sunday as modest mid-level warm air advection continues across the region. Temperatures should exceed 60F for portions of the Wasatch Front Saturday and a majority of the Wasatch Front Sunday. The warming trend will be somewhat short lived though as a more active pattern is expected through much of the next week (discussed more in the long term forecast discussion).

A shortwave ridge will be over the region by Saturday as a weakening shortwave trough crosses into northern California and Oregon. This trough will nudge a relatively weak front into northwestern Utah by late Saturday/early Sunday. This will be a focus for showers later Saturday into Sunday across northern Utah. Additional coverage of showers may reach as far south as Richfield by Sunday afternoon and evening. Meanwhile, a large upper level low will gradually cut off from the mean flow off the Pacific Coast through the weekend and into early Monday. This should shunt the week front north and westward and out of the area by late Sunday.

LONG TERM (After 12Z Monday). EPS/GEFS H5 height anomalies remain in near lock step through forecast hour 120 regarding strength and location of the quasi-stationary closed low that will be evolving off the SoCal coast early next week. After 120hrs do note increased spread developing within the ensembles, namely how fast this closed low will begin to fill, and how fast it will translate east across the desert southwest during the latter half of the forecast period.

With the above said, through 12z Wed confidence is high that the local area will remain on the downstream side of this low, largely within a col between it and a more progressive northern branch flow northeast of the area. An increasingly moist and backing SW-SE flow through the mid levels will allow for the potential for showers Mon- Tue across western portions of Utah, with trends tying more closely to to the Nevada border as flow backs Tuesday. After 12z Wednesday the uncertainty in detail increases as mentioned, but the period between Wed-Thu remains the most likely timeframe for increasing precip both areally and in amounts as this low begins its eastward shift whilst filling. Precip coverage over the far north remains lower confidence than that over central/southern Utah however, as the latter locales will remain tied closer to the low center regardless.

Sensibly, this will remain a fairly "warm" event as flow will aid H7 temps to slowly climb towards and remain near 0C for the period. Although precip amounts are less certain at this time, have much higher confidence that accumulating snows will be relegated to the higher mountain elevations, with showers/rain/isolated storms for the valleys.

AVIATION. Operational weather concerns will remain minimal at the KSLC terminal through the valid TAF period. Light northwesterly winds currently in place are expected to switch back to the southeast between 03-04z this evening per norm, and VFR conditions will be maintained under largely clear skies.

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.
