A small disturbance in southwest flow brought some clouds to Steamboat Springs earlier this Sunday morning, but sunny conditions have returned as the disturbance moves east of our area. This dry weather will persist through the upcoming week, save for Monday when we will see the best chance for showers in north central Colorado.
Moisture moving northward within the North American Monsoon has been high-based so far, and with the lower levels of the atmosphere remaining dry, storms have been hard to come by. Another surge of moisture is forecast to move over our area from the south on Monday, resulting in the best, but still modest, chance of showers for the upcoming week.
Meanwhile, storminess in the Gulf of Alaska is forecast to move eastward across the northern U.S. this week, and the westerly flow will squash the current ridge of high pressure over the Rocky Mountains. The southern suppression of the ridge will sever the flow of monsoonal moisture from the south and bring dry air over the southwestern corner of the country.
Chances for precipitation will decrease markedly for Tuesday and even further for the rest of the work week, with the main weather highlight being the likelihood of breezy west and southwesterly winds on Wednesday and Thursday as the storm track stays well north of our area.
By the weekend, the parade of Gulf of Alaska storms looks to subside, allowing the ridge of high pressure over the Rocky Mountains that had been squashed by the storms to the north to rebound and expand west. This will reopen the door for additional monsoonal moisture to be carried northward toward our area and increase precipitation chances starting around mid next weekend.
