000 FXUS65 KSLC 021528 AFDSLC Area Forecast Discussion National Weather Service Salt Lake City UT 828 AM MST Tue Mar 2 2021 .SYNOPSIS...High pressure will bring a warming trend while maintaining dry weather through Wednesday. The next storm system will impact Utah Wednesday night into Thursday. High pressure returns Friday before another storm system arrives for the weekend. && .DISCUSSION...An upper ridge extends across the central and southern Rockies westward into the eastern Great Basin this morning, downstream from an upper low spinning off the central California coast along 130W. The result will be dry and mild conditions across the forecast area today, with only thin cirrus passing across the forecast area at times. Temps will warm several degrees above climo this afternoon, reaching the low to mid 50s across most western valleys, and upper 60s around the St George area. The exception will be the Bear River and Cache valleys where lingering snowpack has kept a shallow inversion in place. Dry and mild conditions will continue through Wednesday, before the upper low off the California coast ejects through southern and central Utah Wednesday night into Thursday bringing valley rain and mountain snow. The primary question is how far north precipitation associated the deformation axis spreads into northern Utah, with models providing a range of solutions. Any northern Utah precip would likely remain light with snow levels remaining above the valley floors. && .AVIATION...VFR conditions will prevail at KSLC through the TAF period with southeast winds switching to the northwest between 19 and 20Z. && .SLC WATCHES/WARNINGS/ADVISORIES... UT...None. WY...None. && $$ Seaman For more information from NOAA`s National Weather Service visit... http://weather.gov/saltlakecity For frequently asked questions about the Area Forecast Discussion visit... http://weather.gov/saltlakecity/general/afd_faqs.php
