Projected Snow Amounts for Tonight & Outlook to December 21December 10th, 2012 at 3:13 pm by Chad Evans under Chad's WLFI Weather Blog
Some snow showers have been passing just southeast of here today with a few patchy flurries/light snow showers in our area. Upper disturbance will pivot through this afternoon-tonight with some scattered snow showers & flurries across the area. Some of you may have the grass whitened with less than 1″ of accumulation.
This will be followed by partial clearing in places & a sky turning gradually mostly sunny tomorrow.
The week looks largely dry with a warming trend, but subtropical jet will get active with a deep storm roaring southward out of the Gulf of Alaska, into California. This will bring cold rain showers, low snow levels & thunder with small hail into southern California with highs in the 50s.
This storm, which will become embedded in the subtropical jet, will get tossed into the Plains & Midwest, bringing us a wave of rain Saturday.
After this, a split flow regime will resume, but there are indications of our weekend system & an Alberta Clipper merging, forming a Nor’Easter with rain & snow in the Northeast U.S. Meanwhile, another cold-core, rainy, chilly system (with low snow levels & even some t’storms with small hail) will deepn off the coast of southern California. Although we will be in split-flow regime, some of the cooler air from that Nor’Easter may keep it a bit cooler than otherwise in our area.
As we look out to late next week, it appears another substantial storm will impact southern California, while the Nor’Easter exits the Northeast. Meanwhile, former California storm will eject into the Plains & Upper Midwest with snow there, but rain here (we look to be on the warmer side of it).
