Update on Tuesday's Arctic Front

Models continue to show an arctic front surging through the region Tuesday into Tuesday night, bringing with it much colder air for a few days and a chance for a quick shot at wintry precipitation.  While it doesn't look like that big of a deal, I know many people have yet to see their first flakes, so its at least worth mentioning.  Although not much moisture will be associated with the passage, the 00z runs late last night/early this morning have come in a bit more stout for areas even east of the mountains.

It's worth noting that the timing of the front appears to have been trending to an later passage.  This would mean that most precipitation would fall during the daytime hours on Tuesday, possibly causing many lower elevations to just see plain sprinkles/light showers.
