Spot Forecast for Green MTN RX...USFS
National Weather Service Denver/Boulder CO
419 AM MDT Sun Jun 2 2024

If conditions become unrepresentative...contact the National Weather
Service.

.DISCUSSION...Transport winds will become westerly after 1200
today. With today expected to be the warmest day of the year thus
far, temperatures in the area are forecast to climb into the high
70s - low 80s, which will help decrease relative humidity values
to below your 15% threshold. There is a slight chance for some
high-based thunderstorms to develop after 1500 which could cause
gusty and erratic winds. Monday will see slight improvements to
minimum relative humidity values as they are expected to climb to
18%, however, transport winds are forecast to remain westerly
throughout the day.
