Weather Concerns

The weather conditions the past 5 days have certainly lived up to the change in season. And this will be the case for the weeks ahead as we see-saw back and forth from cold to warm. The Low Pressure system which brought us the extended period of precipitation will linger through today before moving east. After today, look for skies to clear as we transition into a 7 day period of drying and warming, High Pressure providing fair weather throughout the upcoming week. Initially this will mean colder nights due to the clear skies, but the flip-side to the forecast is that we will have more sun during the day, a warming treat as we finish off the last week of September.

Friday - Mostly cloudy, brisk and cool with higher elevation snow showers and flurries. Temperatures: 3,500-5,000 ft 39-46 degrees, 5,500-7,500 ft, 28-38 degrees.
