&& .SHORT TERM /FRIDAY THROUGH SATURDAY NIGHT/... As of 220 AM Thursday... High pressure dominates the short term period with with zonal flow aloft. Northwesterly flow could keep some snow upslope snow showers across the mountains into the weekend, but little accumulation is expected. Temperatures will generally run slightly below normal through the period. && .LONG TERM /SUNDAY THROUGH WEDNESDAY/... As of 225 AM Thursday... Not too much in the way of changes from the previous forecast and although the models are coming into better agreement for Sunday into Monday, there is still a large spread for next week. Overall the pattern is looking to be quite active for next week, but uncertain how significant any of these systems will be at this time. Forecast confidence continues to grow for Sunday into Monday with ensemble and operational guidance aligning solutions on a weak or flattening upper trough passing Sunday night into Monday. Starting to think that the chances for precip with this system is decreasing and what was looking like a potential heavy rain event yesterday is now looking like just scattered light rain showers for the area. A blend of model guidance gives chance PoP for this period and that seems adequate for now seeing how the guidance has really pulled back on the QPF with 00Z runs. There after the guidance diverges with timing and intensity of a couple of systems, but they do agree that an active progressive pattern is upon us. && .AVIATION /08Z THURSDAY THROUGH MONDAY/...
