Marine Weather and Tide Forecast for Hooper, UT

DISCUSSION
Near surface moisture did not mix out Thursday across northern Utah valleys, which has resulted in another night of fog/low stratus along the Wasatch Front from roughly the Salt Lake Valley northward, as well as within the Cache Valley.
Anticipate this fog/stratus to hold on through much of the morning before gradually eroding midday, although more sheltered locations such as the Cache Valley may hold onto this fog/stratus well into the afternoon.

A dominant mid level ridge is building into the Great Basin this morning, and will slowly amplify and expand eastward through Saturday, before the ridge axis becomes centered across the forecast area Sunday. As a result 700mb temperatures will trend ~4C warmer today, then climb another ~3C Saturday before warming an additional 2-3C Sunday. Well mixed areas will see a considerable warming trend during this timeframe across the forecast area. However, ongoing fog/stratus will be difficult to fully mix out today across the northern/central Wasatch Front and Cache Valley, and unless that happens these stagnant airmasses will become firmly entrenched owing to warming aloft, with fog/stratus persisting beyond this weekend, and max temperatures likely running well below even the 5th percentile of the NBM, much less the current deterministic NBM.

Confidence is very high in a large scale blocking pattern becoming established across the western CONUS through next week. A weak shortwave is forecast to crest the ridge axis late Sunday/early Monday, however guidance largely keeps this wave well north of the forecast area with only modest low-mid level cooling, and any chance for measurable precip across the northern mountains 10% or less. For valleys with well established inversions this weekend, this wave will not provide sufficient cooling/mixing to dislodge those stagnant airmasses which will then remain in place through next week. Outside of inverted valleys, temperatures will run well above climo for much of next week and resemble early to mid March. Sadly, the next hope for any appreciable precipitation across the forecast area doesn't look to come before the second week in February at the earliest.

AVIATION
KSLC...Dense freezing fog will persist through mid morning with LIFR conditions. Conditions will become VFR once the fog burns off, but there is a 30% chance that fog or low stratus lingers into the afternoon resulting in MVFR/IFR conditions. Winds will remain light and variable with during the foggy period and become light and diurnally driven afterwards.

REST OF UTAH AND SOUTHWEST WYOMING
VFR conditions persist for the central and southern airspace and will continue through the period. IFR/LIFR conditions exist across northern terminals of the Wasatch due to dense freezing fog. This fog will persist through mid morning before burning off. There is a 30% chance patchy fog lingers into the afternoon leading to MVFR/IFR conditions.
Otherwise, conditions will improve to VFR during the day with light diurnally driven winds areawide.

SLC WATCHES/WARNINGS/ADVISORIES
UT...Freezing Fog Advisory until 11 AM MST this morning for UTZ103>105-107.
