Version 3.4 |
12/16/2019 NOAA is having trouble with requests that include wind gusts. I am posting graphs without wind gusts until it gets fixed. 10/9/2019 Updated the Marine Zones. 9/4/2019 Fixed the weather maps due to NOAA moving them. 7/25/2019 New feature in the Airports section gives a link to 5 minute updates for data reports. |

SYNOPSIS. The low pressure system off the southern California coast will turn east and advance into extreme southern Nevada by late Thursday. Somewhat cooler and wet conditions will impact much of Utah through midweek, with drier conditions returning late in the week.
SHORT TERM (Through 12Z Saturday). The upper low currently positioned just off the southern California coast will move inland later this afternoon. From there this low will track slowly east- northeast, reaching extreme southern Nevada by late Thursday.
The initial precipitation associated with the advancing upper low could reach into extreme southwest Utah by late this afternoon. Shortwave energy rotating north ahead of the low through western Arizona will clip the southwest corner by late afternoon. Somewhat cooler air at the mid-levels associated with shortwave along with decent surface heating will likely bring a modest increase to instability across the southwest when the shortwaves passes through the area.
Anticipating a rapid increase in synoptic-scale lift across southern through west-central Utah tonight. Strong, deep layer thermal advection and increasing dynamic lift from the approaching low will lead to an expanding area of light to moderate precip overnight. Locally heavier convective precip will be possible this evening as the nose of the jet reaches into northwest Arizona and extreme southwest Utah.
The low-level baroclinic zone that moved north through southern Utah overnight will likely hold together as rotates into northern Utah Thursday. Solid convergence into this low-level boundary with dynamic support from vorticity lobes rotating around upper low position should generate a band of light/moderate precip along and just north of the baroclinic zone Thursday afternoon and evening. South of this boundary cold air instability along with dynamic support for lift in proximity to the upper low should maintain showery precip across portions of southern and central Utah through early Thursday evening.
The deterministic model guidance continues to show a gradual southwest drift to the low center Thursday night through Friday morning before this features ejects east across southern Arizona Friday afternoon. The deformation axis along the northern flank of the low will reach north to around the Utah/Arizona region Friday afternoon/evening. Showery precip along and south of the deformation will likely remain across northern Arizona, though suspect a few showers will drift in and out of extreme southern Utah during the afternoon/early evening hours. Drier and more stable conditions will move into Utah from the north later Friday night.
LONG TERM (After 12Z Saturday). High pressure will be centered off the Pacific coast to start the forecast period, but a few different storm systems are expected to move over the top of this ridge to impact the weather over Utah and southwest Wyoming. The first one looks like it will impact the area sometime between late Saturday into early Monday. Overall spread in the guidance has decreased noticeably compared to this time yesterday, so confidence is increasing in a significant cooldown for much of the area beginning Sunday. Maxes on Sunday are expected to run at least 5F below seasonal normals, after running up to 10F above those values on Saturday. Some precip is also anticipated, particularly for northeastern portions of the forecast area, but moisture with this system looks a bit limited, which is often the case with back door systems.
After a brief break in the action on Monday, another trough is expected to slide over the top of the ridge into the area Tuesday into Wednesday. Spread in the guidance is higher with this system than the previous, especially with regard to its precise track, however it seems this system will be much weaker than the first one.
AVIATION. The SLC terminal will see VFR conditions throughout the day with mostly clear skies. Southeast winds are expected to shift to the northwest between 17Z and 19Z.

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. |
