KEY MESSAGES
- A strong area of high pressure will bring dry and stable conditions through the next 7 days and beyond. - Weak valley inversions will become better established across northern Utah later this weekend.
- Locations outside of inverted valleys will see max temperatures more reminiscent of early-mid March this weekend through much of next week.
DISCUSSION
Fog is struggling to develop like it has the past couple of nights. A few areas have some reduced vis, such as KSLC (4SM) and Brigham City (5SM), but otherwise most areas remained fog free. Expect only some patchy fog possible before sunset when we should mix out pretty well today, according to model soundings. This will help temperatures climb into the upper 40s and low 50s across Utah valleys with mid 60s in lower Washington county. Given the better mixing during the day the chance of patchy fog for Sunday morning will decrease with <30% chance of fog development.
High pressure will become centered over the area on Sunday with warming and light flow aloft. This will encourage valley inversions to re-establish. However, a grazing shortwave across northern Utah on Monday will bring some cooler air aloft with increasing west/northwest flow that will impede inversion development. Unfortunately, this shortwave will likely be dry. Only 1 of 100 ensemble members have any sort of precipitation with it.
High pressure builds back into the Great Basin by the middle of of the week. Greater warming aloft with weak winds will allow inversions to strengthen with haze likely overspreading northern valleys.
Guidance continues to signal a pattern shift as early as February 9th/10th with dry conditions persisting until then.
REST OF UTAH AND SOUTHWEST WYOMING
Areas of MVFR VIS will persist through the morning within basins of northern Utah, with local areas of dense fog resulting in VLIFR conditions through 16Z. These VLIFR conditions will be most likely to occur at KLGU (40% chance). Elsewhere VFR conditions with diurnal winds can be expected through the TAF period.
