SYNOPSIS. High pressure will remain in place through the weekend.
SHORT TERM (Through 12Z Saturday). Upper level ridging and very dry southwest flow remain present across Utah this afternoon. A few convective buildups are noted on afternoon satellite imagery across the slopes of the Uintas but there is little threat of additional development.
The upper level ridge will continue to strengthen across the Southwest and southern High Plains through the weekend. The ever active northern stream will also shunt through weak shortwave after weak shortwave along the northern tier of the Mountain West.
The net implication will be increasing temperatures across much of Utah through the short term forecast period, with somewhat gusty winds across southern Utah. A red flag warning continues across portions of south central and southeastern Utah through this evening. Did not extend the red flag warning into Thursday as conditions look to be quite isolated given a decrease in 700mb flow.
Those in groups sensitive to heat may be impacted as early as Friday across the lower valleys of Utah as heat risk increases to moderate. The heat will become more impactful to a wider audience in the long term portion of the forecast.
LONG TERM (After 12Z Saturday). Ensemble guidance continues to indicate net pattern amplification across the western CONUS this weekend, with upper ridging building north and overhead in advance of a deepening trough off the PacNW. Warming trend temps remain forecast with this, with the southern tier of the forecast area pushing some 10 degrees above normal along the Arizona Strip. Forecast highs of around 110 degrees in Dixie and 105+ around the Lake Powell coupled with overnight lows in the mid-upper 70s has prompted an excessive heat watch for those areas over the weekend.
Temps will also be maximizing across the north this weekend, but approach and passage of the southern tail of the aforementioned trough passing through the northern Rockies region will aid to knock values back near seasonal norms for the early/mid week period. There remains some slight differences regarding amplitude of this feature within global ensemble means, but not enough to alter trends across the north in a sizable manner. Elevated fire weather concerns from gusty winds and low RH look likely both Monday/Tuesday.
Have maintained a largely dry forecast throughout the long term period, with the only mentionable PoPs relegated to the most prone areas around the Boulder Mountain region Saturday afternoon. Mid and upper moisture will be on the rise across eastern portions of the area at that time, but only modestly so. Any convection within this scenario would remain high based with minimal rainfall.
AVIATION. Northwesterly winds currently in place are expected to hold through 04-05z before returning to a light southeast for the overnight hours. VFR conditions under clear skies will be maintained.
FIRE WEATHER. Gusty winds and low humidities will continue to bring critical fire weather conditions to portions of south central and southeastern Utah this afternoon and evening. Winds will weaken Thursday afternoon and evening through isolated areas of critical fire weather conditions are possible, particularly across the southern mountains.
An increase in mid-level moisture may bring the threat of lightning to portions of southern Utah Saturday afternoon and evening. Gusty winds and low humidities will again bring critical fire weather conditions to much of southern Utah Sunday into early next week.
SLC WATCHES/WARNINGS/ADVISORIES. UT . Red Flag Warning until 9 PM MDT this evening for UTZ493-494-496- 498.
Excessive Heat Watch from Saturday afternoon through Sunday evening for UTZ019-021.
WY . None.

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.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program. |
