FNUS75 KBOU 151012 FWSBOU Spot Forecast for Harris Park RX - Unit O...USFS National Weather Service Denver/Boulder CO 412 AM MDT Thu Oct 15 2026 If conditions become unrepresentative...contact the National Weather Service. .DISCUSSION... There's a chance (40%) for light snow later this morning, but very little additional accumulations are expected. After the showers move south out of the area in the late morning to early afternoon, cloud cover will start to clear. Northerly winds will increase in the early afternoon, with speeds around 10 to 15mph and gusts near 20 to 25mph. The breezy winds will allow for a few hours of good smoke dispersal late this morning and early this afternoon. Winds will weaken around sunset. Tomorrow, expect warmer and drier conditions. RHs will drop close to 25% in the afternoon and precipitation chances will remain very low. Winds will be light on Friday, with speeds generally around 5mph and gusts below 15mph. The light winds and poor mixing heights will leave poor smoke dispersal for Friday. .TODAY...
