Pesky cutoff low influences northern Colorado for the weekend before nice weather returns to start Thanksgiving week
Friday, November 22, 2013
About 2.5” of heavy dense snow on my deck yesterday morning, and another 2” of very light powder this morning, although all of that fell by 6 pm Thursday.
The cutoff low currently to our south and west will wobble eastward through the southern Great Basin and then New Mexico this weekend. While there is a ribbon of dry air just to our north, it appears this will be pushed north of us as this cutoff low approaches. There may even be snow snow showers on Saturday and especially Sunday before clearing for the Thanksgiving week as a ridge builds over the west coast behind the departing storm.
Incidentally, it appears this storm will create issues along the Gulf Coast early in the week before possibly turning into a major Nor’easter. This will likely affecting the entire eastern seaboard right around the Thanksgiving holiday, especially if it phases with another storm forecast to be along the Canadian border around that time.
There may be some showers near the end of the week as a storm off the coast interacts with the ridge and begins to send some energy over our area, although the latest model run keeps the storm too far west and south for that. It appears we won’t get a lot of weather from this storm, but it may set the stage for colder air from Canada to begin to affect the northern Rockies by the week after Thanksgiving.
