086 FNUS75 KSLC 150048 FWSSLC Spot Forecast for Little Twist...Richfield Interagency Fire Center National Weather Service Salt Lake City UT 648 PM MDT Fri Jun 14 2024 Forecast is based on forecast start time of 1900 MDT on June 14. If conditions become unrepresentative...contact the National Weather Service. ...STRONG, DRY COLD FRONTAL PASSAGE EXPECTED MONDAY EVENING... .DISCUSSION...Gusty west to southwest winds will remain in place through the weekend at ridgetop level, with canyons and lower elevation areas experiencing drainage winds each night. Due to a slightly stronger pressure gradient on Saturday, it will take a bit longer for drainage winds to develop Saturday evening. Otherwise the trend through the weekend will be breezy daytime conditions with poor overnight humidity. A strong, dry cold front for June standards will plow through the area Monday evening. Ahead of the front on Monday, transport winds will increase to around 30-35 mph in the afternoon, and min humidity will be in the 10-15 percent range. Wind direction will shift abruptly to the northwest and north Monday evening as the front moves through, and winds will be similarly gusty along/behind the front through the rest of the evening before winds gradually decrease Monday night behind the front. Current forecast suggests the cold front will pass through the area between 1800-2100 Monday evening. This window could shift slightly as we get closer. Slight RH recovery expected Tuesday morning behind the front with RH climbing into the 45-55 percent range. Min RH on Tuesday, however, looks similarly low to the past several days, back into the teens. .TONIGHT... Sky/weather.........Mostly clear (15-25 percent cloud cover). CWR.................0 percent.
