Area Forecast Discussion National Weather Service Salt Lake City UT 1011 PM MDT Thu Aug 13 2020
SYNOPSIS. With a ridge of high pressure building over the Great Basin, temperatures will warm significantly heading into the weekend. The hot weather will continue into early next week, with readings on the order of 5 to 15 degrees above normal. Aside from some isolated thunderstorm activity over the mountains, dry weather will prevail.
DISCUSSION. The last Red Flag Warning of the recent batch has been allowed to expire as of this evening. A few pockets of breezy winds are still possible over the northern UT mountains tomorrow and Saturday, notably from the Wasatch Plateau to the Uintas, but widespread Red Flag conditions are not expected at this time. Beyond that, all the focus turns to a prolonged heat wave which is on our doorstep starting this weekend, and lasting through the foreseeable future. Multiple records will fall by late this into early next week.
No forecast updates this evening.
PREVIOUS FORECAST DISCUSSION. ISSUED 418 PM MDT . A shortwave trough is pushing through the Northern Rockies this afternoon resulting in a tightened pressure gradient across northern Utah while high pressure continues to build westward across New Mexico. This is driving gusty winds across the higher terrain in northern Utah and across southwest Wyoming, which combined with very dry air and antecedent conditions is resulting in critical fire weather conditions. Red Flag Warnings remain in place through this evening.
Winds will diminish tonight, with a weakening trend in the winds on Friday as the trough will have exited well to our east and the mid level ridge amplifies and retrogrades becoming centered over Arizona. This will signify the start of the long-duration heat event across the Great Basin. On Friday temperatures will warm in earnest across far southern Utah, while northern Utah gets to enjoy one last day of near-normal temperatures before the heat ramps up.
By Saturday, the mid-level ridge will remain centered over northwest Arizona, but will continue to amplify in place with anomalous heights developing northward across the intermountain west. Southern Utah will start to become entrenched in the hot temperatures that are expected to continue well into the first half of next week, while temperatures across northern Utah start to rise 5-10 degrees above average.
LONG TERM (After 6 AM Sunday). A very strong ridge will remain basically over the western CONUS through the extended period with record challenging heat Sunday and Monday. However, the center of the ridge will slide a little farther south as a shortwave kicks into the Canadian Rockies later Tuesday. The net result will be temperatures trending down just a tad from Tuesday forward.
Both the GFS and EC show some 500 and 300 mb moisture moving in over the CWA from the west and northwest, but it's probably overdone as the ridge axis remains pretty much along the western portion of the state, keeping the descending motion across the remainder of Utah so amount of clouds probably not as significant as models show. There will be some increase in thunderstorm potential over the higher elevations mainly Wednesday and Thursday, although an isolated high- based thunderstorm is possible over the Uintas Tuesday afternoon and evening.
AVIATION. VFR conditions to continue at the SLC terminal through the valid TAF period as skies remain mainly clear. Northwest winds go back to southeast around 04Z tonight, before switching back to the northwest around 17Z Friday.
FIRE WEATHER. Critical fire weather conditions will wind down this evening in the wake of a low pressure system moving through the Northern Rockies today, resulting breezy and dry conditions.
An area of high pressure across the desert Southwest will build over the Great Basin heading into the weekend, then hold in place. With the ridge, temperatures will turn hot, running 5 to 10 degrees above normal through the weekend and into next week. Some moisture return in the mid levels may be sufficient enough for the development of some elevated convection each afternoon from Tuesday into Thursday, though again, little in the way of rainfall is expected. The primary hazards will be gusty and erratic winds, along with lightning strikes potentially producing ignitions.
SLC WATCHES/WARNINGS/ADVISORIES. UT . Excessive Heat Warning from 6 AM Friday to midnight MDT Wednesday night for UTZ019-021.
Excessive Heat Watch from Sunday afternoon through Wednesday evening for UTZ001>005-011>016-020.
WY . Red Flag Warning in effect until 8 PM MDT Friday for WYZ277.

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. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
