Area Forecast Discussion National Weather Service Salt Lake City UT 352 PM MDT Thu Aug 6 2020

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

SHORT TERM (Through 12Z Sunday). Broad upper level ridging remains in place across the southern Plain, stretching into portions of the Desert Southwest. A shortwave trough embedded in the northern stream will cross the northern Intermountain Region this evening into Friday morning. The associated cold front will cross into northern Utah Friday morning and aid in cooling temperatures to closer to normal levels across much of the state Friday into early next week.

As expected, a few thunderstorms have developed across the always favored Raft Rivers this afternoon and evening. This convection will remain weak and largely high-based.

Outside of convection along the Raft Rivers this weekend, there is little chance of precipitation through the short term forecast period as Utah will remain in dry southwesterly flow.

Current red flag warnings go through this evening. Winds will be lighter Friday into the weekend . so this should end the need for any fire weather headlines after today.

LONG TERM (After 12Z Sunday). The extended forecast looks to remain dry with the exception of slight chances for afternoon/evening showers/storms in and near the Raft River and Uinta Mountains. Temperatures will remain near to slightly above average.

A ridge will be centered across southern New Mexico at the start of the period allowing for zonal flow across Utah and southwest Utah. A trough moving into British Columbia early next week will begin to deamplify this ridge starting Tuesday. Models are in good agreement through Tuesday.

Model solutions begin to diverge Wednesday and Thursday regarding the evolution of the aforementioned trough across British Columbia. A majority of the GFS ensemble suite phase the trough with a weak closed low off the CA coast, resulting in a slower progressing and deeper trough across the far western US. Roughly half of the CMC ensemble members also follow this trend with the other half following a faster progressing, less amplified trough depicted in the ECMWF ensemble. These differences do not have much impact on sensible weather as even the GFS solution keeps a dry slot across the area, confining any PoPs to the Raft River and Uintah ranges. The main impact of these differences will involve fire weather threat as GFS has stronger 700-500 mb southwest flow vs much weaker W/SW flow in the ECMWF solution.

AVIATION. The SLC terminal will see VFR conditions throughout the TAF period, with mostly clear skies. Southerly winds will persist during the daytime hours, with gusts hovering around AWW criteria expected through about 23z. There is a 10 percent chance winds become westerly after 00z, before the diurnal switch to southeasterly at 03z.

FIRE WEATHER. Broad ridging remains across the southern Plains into the Desert Southwest this afternoon. A trough embedded in the northerly stream, while remaining well north of the region, will help to bring a weak cold front into the state Friday. This will have the effect of finally cooling temperatures to closer to normal levels. 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 until 9 PM MDT this evening for UTZ478-479- 481>484-488-489-492>498.

WY . Red Flag Warning from noon to 8 PM MDT Thursday for WYZ277.

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.
