855 FXUS65 KSLC 240824 AFDSLC Area Forecast Discussion National Weather Service Salt Lake City UT 224 AM MDT Tue Sep 24 2024 .SYNOPSIS...High pressure will bring above normal temperatures, relatively light winds, and very low precipitation chances to the Great Basin through at least the next week. && .SHORT TERM (Through 12Z/6AM Thursday)...High pressure will build into the Great Basin today, gradually shifting eastward before settling over CO/NM by Wednesday. Temperatures will continue to increase, likely peaking Wednesday afternoon around 5 to 15 degrees above normal. Although highs will approach 90F along the Wasatch Front and 100F in Lower Washington County, daily records may be hard to beat at both KSLC (93F) and St. George (103F). Otherwise, precipitation chances will remain near zero and winds will remain relatively light. Dare we say the "Q" word (quiet)? .LONG TERM (After 12Z/6AM Thursday)...The vast consensus among members of all ensemble system continues to be mean ridging will remain across the region through at least Monday. A very weak dry cold front may bring a reduction of 1-3 degrees across mainly northern Utah Thursday afternoon. After that, the next hope for any kind of pattern shift is toward middle to end of next week, with around 20% of members showing a deep trough, 25% of members showing continued ridging and the remainder some semblance of zonal flow. && .AVIATION...KSLC...Light southeasterly drainage winds will continue through the morning hours at SLC, with a switch to the northwest expected between 1800-1900Z. .REST OF UTAH AND SOUTHWEST WYOMING...Mainly clear skies will be the rule across most of Utah and southwest Wyoming today. Expect terrain driven winds for all terminals. && .FIRE WEATHER...High pressure will move overhead today, producing a slight warming trend and light, terrain-driven winds. This high will slowly move eastward, producing southwesterly flow and further warming and drying on Wednesday. Minimum RH will fall below 15% in most valleys, with marginal to poor overnight recoveries. High pressure will likely persist, with no precipitation chances over the next 7 days. Winds will largely remain light and terrain-driven. && .SLC WATCHES/WARNINGS/ADVISORIES... UT...None. WY...None. && $$ Cunningham/Kruse For more information from NOAA`s National Weather Service visit... http://weather.gov/saltlakecity
