Potential of Accumulating Snow Increasing In Late December After ChristmasDecember 14th, 2012 at 1:55 pm by Chad Evans under Chad's WLFI Weather Blog
POST CHRISTMAS PATTERN CHANGE……….
Colder weather pattern & active subtropical jet will promote increasing potential of accumulating snowfall in late December after Christmas.
Persistent Canadian high will promote lots of dry, sunny weather at first, but storm systems in the Southwest & West U.S. & continually active subtropical jet will bring a couple to several opportunities for some accumulating snowfall.
In terms of the weekend forecast, showers are still a good bet Saturday with the greatest concentration (perhaps even an isolated t’storm) late morning-midday, followed by more spotty showers/sprinkles/drizzle afterward (& a few spotty showers/sprinkles before). Given the fact that the main lift for rainfall will be well out ahead of the cold front, it appears the actual front may not pass until Sunday. So, I prefer to keep a couple showers in the forecast for Sunday & keep it warm, at least for the first half (followed by falling temperatures).
This same storm has brought a lot of rainfall to the Desert Southwest & in California. Heavy snowfall is falling in Arizona to Utah, Nevada & in the mountains of southern California.
As the storm system departs & a Nor’Easter begins to form on the East Coast, a shortwave will pivot around it & may bring a couple showers/flakes to the area Monday.
Looks dry & turning warmer.
Storm system is accelerating & will pass with showers. Most likely we will hit high temperature fairly early in the day, then fall to near 40 in the late afternoon.
FRIDAY (DECEMBER 21) TO TUESDAY (DECEMBER 25)…………
It looks dry, bright, cold & tranquil. Persistent, significant lake effect snows will be on-going well to our northeast, but I wouldn’t be surprised to see at least some of these snow showers affect Fulton/Miami, perhaps Pulaski to Cass counties with some minor accumulation. There will be lake effect cloudiness there, too, whereas much of the viewing area will be brighter during this time period.
Highs will likely run 29-35 with lows of 14-18.
