Marine Weather and Tide Forecast for Hanksville, UT

DISCUSSION
Looking at the 12z upper air sounding from KSLC, it appears that a warm layer aloft remains, though it has lifted somewhat higher as the boundary layer deepens. As such, we can expect another day of improved air quality and visibilities across much of northern UT today. Additionally, this will encourage mixing yielding drier air at the surface today compared to some of the more humid conditions the past few days which yielded low stratus and instances of patchy fog.

Currently, a longwave trough is slowly progressing east with its axis positioned across the Southeastern U.S. while ridging to our southwest gradually regresses further south. This will continue ushering in northwesterly flow on the backside of the aforementioned large upper trough through at least Wednesday. Within this flow, embedded perturbations will clip northern UT each day enabling some colder air aloft with enhanced flow, serving to cool down and mix above the boundary layer and perhaps lifting inversions higher as a result. A weak frontal boundary may pass through northern UT Tuesday afternoon, though confidence has decreased somewhat regarding the overall magnitude and if it will lift the inversion further. As such, haze (at or below 6SM visibilities) will remain in the forecast Tuesday afternoon through Thursday evening.

Forecast confidence regarding our next shot at precipitation has unfortunately all but improved as we approach the weekend. While the general consensus among ensemble members supports troughing across the Western U.S., the timing and positioning have diverged quite substantially. Looking at current ensembles, it appears we have returned to early season form with southern UT being favored due to a southern storm track, though much of UT and SW WY can expect to see at least a trace of precipitation. For solutions favoring northern UT, roughly ~50% of ensemble guidance supports more than a trace of precipitation from the Fri-Sun timeframe. The silver lining with this set up, at least, is that enough cold air should advect into the area to scour inversions and improve air quality as we enter the weekend.

AVIATION
KSLC...VFR conditions are expected to prevail through the forecast period under mostly clear skies. There is around a 20% chance or lower that visibilities will dip into MVFR or below late tonight into Monday morning. Light north to northwesterly winds are expected to continue through Monday afternoon, with periods of light and variable winds.

REST OF UTAH AND SOUTHWEST WYOMING
VFR conditions are expected to prevail across all terminals through the forecast period, although there is around a 20% chance that visibilities will dip into MVFR or lower late tonight into Monday morning mainly near the Idaho border. Winds will remain generally light and terrain driven through much of the period, with light northerly winds becoming more widespread across northern and western Utah through the evening hours.
