Area Forecast Discussion National Weather Service Salt Lake City UT 418 AM MDT Fri Aug 7 2020

SYNOPSIS. Persistent high pressure will keep a typical warm but dry summer pattern across the region through early next week.

SHORT TERM (Through 6 AM Monday). A trough moving through the Northern Rockies will push a weak, dry cold front into central Utah today. This will usher in slightly cooler temperatures across northern Utah, with high temperatures running closer to seasonal averages. Meanwhile, ahead of the front, breezy, warm and dry conditions will continue across southern and eastern Utah. This combination of winds and dry conditions will result in critical fire weather conditions, and Red Flag Warnings have been issued.

Otherwise, the weather pattern will remain fairly stagnant through the weekend as high pressure remains centered over Texas and a very weak trough retrogrades from over California to just off the west coast. This will maintain a dry southwesterly flow into the forecast area, while the northern stream activity over the northern Rockies helps to suppress the ridge from building into Utah Long story short. seasonal temperatures and dry conditions will prevail through the weekend.

LONG TERM (After 6 AM Monday). High pressure centered over the Desert Southwest will keep generally dry conditions over the forecast area during the long term period with temperatures near seasonal normals. The flow aloft will initially be zonal in nature with the ridge flattened by a trough passing to the north. However, as the ridge amplifies and a trough approaches the Pacific coast midweek, the flow will gain more of a southerly component.

There are some indications the pattern may get more interesting by the end of the forecast period as a colder trough approaches the Pacific Northwest coast during the latter part of the work week. Global models and ensembles are showing significant spread with regard to the evolution of this system. The GFS and GEFS favor a solution that digs the trough into northern Utah by late Friday, bringing noticeably cooler air to at least northern Utah. However, the EC and EPS keep the system farther north and associated impacts would be more limited. For now, have indicated a slight cooling trend for day seven.

AVIATION. The SLC terminal will see VFR conditions throughout the day with mostly clear skies. Southerly winds are expected to shift to the northwest between 19Z and 21Z.

FIRE WEATHER. A trough moving through the Northern Rockies will push a weak, dry cold front into central Utah today. Ahead of this front, breezy, warm and dry conditions will redevelop today for portions of southern and eastern Utah resulting in critical fire weather conditions. Meanwhile, slightly cooler temperatures, closer to average, will return for northern Utah behind the front.

Temperatures will remain near normal into early next week. A few thunderstorms are possible each afternoon and evening through Sunday across the Raft River Mountains, otherwise the chance of precipitation is near zero for most of the rest of Utah into early next week.

SLC WATCHES/WARNINGS/ADVISORIES. UT . Red Flag Warning from 10 AM this morning to 9 PM MDT this evening for UTZ484-489-493-494-496.

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.
