High pressure at the surface and aloft. Air aloft remains fairly dry which is especially apparent in the skew-T from Denver this morning.  By Saturday morning, a surface high will be to our southeast which should bring southwesterly flow.  It looks like a very weak cold front will come down from the north directly to our east Saturday around midday which will maintain the southwesterly flow.  A stronger cold front associated with a low in Canada will pass through late Sunday or early Monday.  Once this cold front passes there will be a chance for northwesterly flow, but the 12Z runs of the NAM and GFS show a surface high to our north and a surface low to our south which suggests northeasterly flow. The low pressure will move out on Tuesday and flow will be northwesterly as a trough deepens through the upper Midwest.  This will continue through most of Tuesday, and by Tuesday night the deepened trough will have moved more towards the northeast, giving us the chance for west-northwesterly flow. Slight chance for scattered showers late Monday into Tuesday.
