####018008640#### FNUS75 KBOU 251811 FWSBOU Spot Forecast for Shooting Range RX...USFS National Weather Service Denver/Boulder CO 1211 PM MDT Thu Apr 25 2024 If conditions become unrepresentative...contact the National Weather Service. .DISCUSSION...Chances for showers will gradually increase through the afternoon and evening today. The best chance of a wetting rain is between 5-9PM this evening as a more organized round of showers moves through the region. Isolated to scattered rain and snow showers are expected tonight with minimal snow accumulation anticipated. Winds should generally remain out of the west today, though any stronger showers or storms could briefly shift wind directions briefly. Humidity values are near 20% already and should hover in the 15-25% range through the rest of the day. Another round of rain and snow showers is expected Friday into Friday night. These will again be rather hit-or-miss through the day with generally light precipitation amounts expected. Some minor snow accumulation is also possible, mainly Friday evening into Friday night. Winds will again remain fairly steady out of the west through the period. A more organized system is expected to bring widespread precipitation (mainly snow) to the area, with several inches of snow possible through the weekend. The heaviest precipitation is forecast to fall Saturday into Saturday night. Our current forecast calls for roughly an inch of liquid to fall from Friday evening through Sunday morning. Snow levels remain somewhat uncertain, but 2-5 inches of snow is forecast across the valley, with over a foot of snow likely on the ridges just east of the spot location. .REST OF TODAY...
