KEY MESSAGES

- Patchy fog continues through tomorrow morning.

- Light rain spreads north in the afternoon, continuing through Monday.

- Generally dry weather is expected through the remainder of the week.

DISCUSSION

Upper trough will continue digging into the western states today. Fog will continue to impact portions of the region through the morning with some locally dense fog, reducing visibility in spots to 2 mile or less.

As the Pacific upper trough moves through the Great Basin, a Colorado low is expected to develop ahead of it. This will spread precipitation northward, and will generally favor the Yellowstone basin tonight into Monday. Splitting in the upper trough near the Canadian boarder will keep cold air from being drawn southward, and result in little to no mixed precipitation or snow. As the surface low deepens, an increase in winds will result by Monday afternoon.

A progressive, unsettled pattern will keep next week interesting with repeated upper level troughs.

FORECAST CONFIDENCE & DEVIATIONS:

No changes to NBM. A lot of uncertainty regarding fog, low cloud and precipitation today.
