074 FXUS65 KSLC 230812 AFDSLC Area Forecast Discussion National Weather Service Salt Lake City UT 212 AM MDT Mon Sep 23 2024 .SYNOPSIS...Dry and mild conditions will persist as high pressure builds across the Great Basin, with temperatures increasing to 5 to 15 degrees above normal by Wednesday. && .SHORT TERM (Through 12Z/6AM Wednesday)...A weak disturbance will graze by our area today, bringing some high clouds to much of the area and breezy northwesterly winds up to 20-30 mph across Uinta County, WY this afternoon. Otherwise, building high pressure across the Great Basin will produce dry and mild conditions across Utah and southwestern Wyoming. Summer isn`t quite ready to say goodbye; temperatures will likely increase into the upper-80s along the Wasatch Front and upper-90s in St. George by Wednesday. .LONG TERM (After 12Z/6AM Wednesday)...With broad ridging forecast by all members of all major ensemble systems through Sunday, there isn`t much to say for most of the long term forecast period. As one would expect, differences begin to creep in by next Monday, with a minority of solutions bringing a deep trough through the region. Among the solutions indicating a deeper trough, the majority remain dry across the state. Essentially a lot of words to say: near to above normal temperatures and below normal precipitation look to be a near certainty through at least Sunday if not next Monday. && .AVIATION...KSLC...Light southeasterly drainage winds will continue through the morning hours at SLC, with a switch to the northwest expected between 1630-1730Z. .REST OF UTAH AND SOUTHWEST WYOMING...Mainly clear skies will be the rule across most of Utah and southwest Wyoming today. Northern Utah may see a bit of a northerly gradient today, however the remainder of the region will see diurnal/terrain-based winds. && .FIRE WEATHER...High pressure will build across the Great Basin, producing a warming and drying trend through at least Wednesday, after which temperatures may stabilize or decrease slightly. Precipitation is very unlikely over the next 7 days, and winds are likely to remain terrain-driven. Min RH will approach critical by Wednesday across most valley locations, with a decreasing trend for overnight recoveries, too. && .SLC WATCHES/WARNINGS/ADVISORIES... UT...None. WY...None. && $$ Cunningham/Kruse For more information from NOAA`s National Weather Service visit... http://weather.gov/saltlakecity
