Marine Weather and Tide Forecast for Kanab, UT

.SHORT TERM (Through 12Z/6AM Sunday)...Seeing a weak frontal boundary over central Utah this morning with the associated grazing trough now well east of the area. Seeing some clouds lingering along and head of the front, with mostly clear skies behind it. Will see a slight dip in temperatures today, up to 5F less warm than yesterday for northern portions of the area with only a degree or two of difference for southern Utah. Will continue to see breezy conditions persist, primarily ahead of the front. Given this area will also remain drier, will see the potential for marginally critical fire weather conditions.

A Pacific trough will make its way onshore along the California coast during the day today, splitting as it does so. The first and weaker piece is on track to graze northern Utah tonight into Saturday morning, bringing an ever so slight decrease in highs Saturday for northern portions of the area and enough lingering moisture and instability for a few afternoon showers along the associated boundary over northern Utah. The second and larger piece of the system is expected to close off over the Great Basin during the day Saturday, approaching western Utah by Sunday morning.

.LONG TERM (After 12Z/6AM Sunday)...The axis of a splitting trough will be centered over Utah to start the period on Sunday.
This splitting trough will help to initiate some diurnal convection, primarily across the terrain of central and northern Utah during the day on Sunday. It's starting to look like this will be a rinse-and- repeat pattern throughout most of the remainder of the long term period as another trough splits to our west with a weak cutoff low meandering across the Great Basin through the end of the week before more significant warming aloft commences as a broad ridge builds across the western CONUS later in the week.

This diurnal convection will be limited in strength given weak instability profiles. The primary threat with this convection will be lightning with the potential for some gusty outflow winds. QPF will also be limited given that moisture will primarily be confined to the mid and upper levels. This will certainly be the case the further south you go. One of the biggest benefits of this pattern will be that it will cap diurnal maxes from getting too abnormally hot. Conditions will still be warmer than normal, but now conditions look to be ~10 degrees above normal for most of next week rather than 15 degrees above normal which looked to be the case in previous forecasts. However, by the end of the week the closed low progresses further east and temperatures begin to warm even more with the potential for our first 90 degree day of the year at KSLC by the end of next week into the weekend.

AVIATION
KSLC...VFR conditions will persist for the KSLC terminal through the period. Dry and stable conditions will continue. Light southerly drainage winds will transition to a light northerly lake breeze during the afternoon with only a few high level clouds.

REST OF UTAH AND SOUTHWEST WYOMING
VFR conditions will persist for the airspace throughout the period. Dry and stable conditions with a few high level clouds will continue. Winds across the northern airspace will be light and diurnally driven with stronger southerly winds developing during the day across the central and southern portion of the airspace.

FIRE WEATHER
With a weak front stalled over central Utah, locations ahead of the front will stay dry and breezy, resulting in near critical fire weather conditions. Over northern Utah, relative humidities will be higher and winds lighter behind the front, resulting in less fire danger. A series of weak storm systems will move across the area Saturday into Sunday, bringing an increase in relative humidity, a decrease in temperatures, and scattered showers for northern Utah. As high pressure moves back in, drier and warmer conditions will develop to start the work week.

SLC WATCHES/WARNINGS/ADVISORIES
