Tonight, however, strong low level moisture will be advected northward into the region ahead of this trough. This will continue the low stratus we have seen all day today. A lead short wave trough within the long wave will move out from the four-corners into the central Plains on Sunday. Surface lee cyclogenesis over eastern Colorado will drag a Pacific cold front/dryline through the area during the daytime.
A weak mid-level ridge was in place across the central U. and low pressure over the High Plains. This afternoon a mid-level trough moved into the western U. , and models show this trough quickly advancing eastward toward the Rockies tonight into Sunday. Southerly winds will remain sustained at 10-15mph as the low-level jet remains centered over the area. As a result, the low temperatures may occur near midnight tonight with temperatures remaining steady or rising slightly overnight into Sunday morning. Models show the low-level jet increasing through the day, especially during the afternoon/early evening hours, with 850mb winds of 50-60kts. expect scattered showers and isolated thunderstorms to persist through at least 6z as intense lift ahead of the upper low pivots across the area.
RAP soundings suggest that there will be a strong low level inversion which will trap some moisture in at the low levels. Medium High clouds will continue into the evening, but will probably clear out for a time tonight before returning tomorrow ahead of approaching low pressure.
