UNSEASONABLY WARM AND DRY THROUGH FRIDAY:

High pressure will persist through the work week bringing unseasonably warm and dry conditions. Temperatures are expected to run 5-10 degrees above normal through Friday.

WET WEATHER RETURNS THIS WEEKEND:

An unsettled weather pattern sets in this weekend beginning with a fast-moving low pressure system. This system arrives Saturday with a bulk of its precipitation falling Saturday afternoon and evening with the arrival of moisture-rich southwesterly flow ahead of the low. Mountain snow is favored above 8,000-9,000 feet with valley rain below. Isolated thunderstorms are possible as well, especially during the afternoon hours. Over the southern San Juans, NBM guidance currently shows a high likelihood (>80% chance) of 6+ inches of snow over 10,000 feet and a lower likelihood (< 30% chance) of 12+ inches. Mountain snow is likely elsewhere, however the potential for 6+ inches is generally lower than the San Juans. The Grand Mesa and central Divide mountains have the next best chance of seeing amounts over six inches. We'll have a better handle on snow amounts with the addition of hi-res guidance over the next 24-36 hours. Impacts wise, slippery to hazardous travel is possible over mountain passes with reduced visibility while it's snowing.

Snow levels drop to around 7,000 feet after the passage of a cold front on Sunday morning. However, precipitation chances will be winding down by then with light snow lingering over the northern and central mountains. Otherwise, cooler and drier conditions take hold for the remainder of the weekend.

LOOKING AHEAD:

A wavy pattern remains in place next week with another round of valley rain and mountain snow possible by Tuesday or Wednesday. Forecast confidence is very low at this time due to sizable differences in the timing, strength, and track of the next low pressure system. A wide variety of solutions remain on the table...some more impactful than others.
