TODAY-WEDNESDAY EVENING:
A brief flurry of light snow is possible early in the week. Timing is problematic. Some data moves it more to Tuesday evening-Wednesday AM, and not Monday evening-Tuesday AM.
I ended up putting in a potential for brief light snow Monday night-Tuesday AM AND Tuesday night-Wednesday AM given the uncertainty.
Any buildup would be 0.5″ or less and not everyone will see the buildup.
This after a slow, slow clearing trend today with highs at 25-30 then lows tonight at 11-16. Clouds will rise tomorrow from 28 to 32.
Tomorrow night’s 22-26 should give way to Tuesday’s 31-34.
The winds seem quite light and largely from the west.
After 28-32 Wednesday, we go to 18-22 Wednesday evening.
THURSDAY-SATURDAY EVENING:
First, Thursday:
Winds will increase Thursday as we become cloudy. Snow will cover the area from the afternoon into the evening, with conditions dropping fairly quickly as winds increase to 25-40 mph from the east. Sleet may occur early in our southern counties.
Highs of 27-32 are expected.
From Thursday evening to Friday evening:
Widespread Thursday night snow is expected to last through Friday with Thursday night lows at 0-6 with wind chills at -25. Friday highs are expected to be just 6-12 with wind chills at -17.
Conditions will continue to deteriorate with the worst of the wind, with near whiteout conditions occurring on Friday.
Northwest to north winds can blow at 45-54 mph (sustained winds 25-35 mph) with near-blizzard conditions. Visibility can drop to less than 0.25 mile in falling snow and heavy blowing snow and blowing snow.
Conditions will still be very poor on Friday evening with lows of -6 to -2 and wind chills of -33 to -25. Light snow and lots of blowing and blowing snow will occur with near whiteout conditions.
Saturday-Saturday evening:
Although the snow will ease by Saturday, north to northwest winds could blow up to 43 mph on Saturday with a few scattered lake-effect flurries.
The blowing and drifting really won’t stop completely until noon on Sunday.
Saturday’s wind chills (with highs of 4 to 9) will be -12 to -20.
The snow is easing Saturday evening, but lows of -13 to -8 are expected with wind chills of -25 to -39.
A WIND CHILL WARNING MAY BE ISSUED.
A WINTER STORM WATCH IS LIKELY ISSUED WITH A LIKELY WINTER STORM WARNING UPGRADE AND POSSIBLE BLIZZARD WARNING UPGRADE FOR PARTS OF THE VIEWING AREA.
A FEW TO SEVERAL INCHES OF SNOW ARE EXPECTED.
THIS SEEMS LIKE THE MOST IMPACT WINTER WEATHER FOR A CHRISTMAS HOLIDAY PERIOD SINCE 1983 (COMBINATION OF STRONG WINDS, SNOW ACCUMULATION AND BRUTAL COLD WITH DANGEROUS WIND CHILLS).
2000 HAD SNOW AND BRUTAL ACTUAL AIR TEMPERATURES, BUT LACK OF HIGH WINDS.
1989 HAS SNOW ON THE GROUND, BUT WORST WEATHER WAS BEFORE HOLIDAY PEAK.
1985 LOOKED BRUTALLY COLD, BUT LACK OF WIND AND HEAVIER SNOWFALL.
1983 HAD BRUTAL COLD, SNOW AND WIND WITH DANGEROUS WIND CHILLS.
SUNDAY MONDAY:
Sunday looks mostly sunny to sunny, but cold with highs of 5 to 9 and Sunday evening lows of -16 to -10.
This is an incidence of transpolar flow in which the brutal cold is strong from Scandinavia to Siberia through Alaska and Alberta before it is released to the southeast.
So it’s often much warmer in Alaska when it’s this cold in western Canada down to Lower 48. In this case, it will be near -40 in central Alaska down to Alberta and even Montana and the Dakotas can drop to near -40. It will even be near record/record cold over Washington and Oregon, Idaho to Utah and some of that cold will even seep into central California.
It really is a large and widespread outbreak in the Arctic, aided by the release of the polar vortex. A lobe of it will swing across Canada to the northern United States
Such transcontinental brutal cold hasn’t been seen at Christmas in such a way since 1983.
You also won’t escape cold Florida with possible upper 20s as far south as the Orlando area with upper 30s all the way to Homestead, Florida.
Blowing and drifting develop Monday through Monday evening (southwesterly winds developing and increasing to 20-30 mph) with increasing clouds.
Our high of 18-22 Monday will likely be reached around 11:45 p.m. Monday evening after afternoon highs of only 10-16.
Temperatures are expected to reach 32-35 on Tuesday with blowing snow and blowing snow and southwesterly winds up to 40 mph.
The sky looks cloudy.
TUESDAY EVENING (27-28 DECEMBER)-EARLY JANUARY:
A flurry of mixed icy and snow could occur Tuesday evening through Wednesday morning with temperatures peaking at 32-34 before dropping to 29-32.
Highs in the 30’s with westerly winds are expected next Wednesday (December 28).
Mixing with rain then a brief snowfall is possible around New Years with 30s to 40s dropping to lows below 0 in early January.
