While one trough of low pressure to our north drags a dry cool front through the region today and tonight, another trough crosses the Pacific Northwest coast on Sunday and splits, with the southern portion closing off and taking up residence in the Great Basin for the upcoming work week.
The weekend will be sandwiched between these troughs and feature beautiful warm sunny days and quite cool nights with outdoor plants likely needing help to make it through the around-freezing temperatures on Saturday morning.
The southern portion of the split will force our winds to back from the current northwest to southwest by Sunday night, allowing a tap of subtropical moisture to flow over Colorado. A cool front associated with the passing northern part of the split on Monday will likely enhance showers by the afternoon that may extend into the evening as it swings through the area.
Though the heaviest showers will pass as the northern part of the split moves east of the area on Monday, the lumbering Great Basin low will allow moisture to remain over our area, continuing the chance of afternoon showers through most of the work week.
