571 FNUS75 KSLC 302001 FWSSLC Spot Forecast for Little Twist...Richfield Interagency Fire Center National Weather Service Salt Lake City UT 201 PM MDT Sun Jun 30 2024 Forecast is based on forecast start time of 1800 MDT on June 30. If conditions become unrepresentative...contact the National Weather Service. .DISCUSSION...Very warm and dry conditions with gusty afternoon winds will persist across the fire area again Monday, ahead of a dry cold front which will cross the site Monday evening. Winds Monday will predominantly be from the west-southwest (250-260 degrees), with the strongest winds along exposed ridgelines and through wind-aligned drainages during the afternoon and early evening hours. Overnight recovery is expected to be marginal Monday morning, allowing RH to fall below 30% by mid morning as winds begin to develop. As the dry front passes Monday evening, winds will become northwesterly and remain elevated for a couple of hours before diminishing overnight. A cooler but dry airmass will follow for Monday under general northwesterly flow. A further drying trend will follow for the middle to latter portion of the upcoming week, with very low daytime RH and marginal to poor overnight recoveries. .MONDAY...
