UPDATE: Wed 9 Feb 2010 / 10:15 a.m.
The mid-level trough's core tracked about 75 miles further north than expected; this slight jog was enough to keep Texoma snowfall amounts to generally 1 to 4 inches.
Now the bad news: clearing skies will allow for record cold tonight ranging from zero to 8 degrees!
Thursday will be sunny and cold with highs near freezing. After another very cold morning Friday, milder weather should remove any remaining snow from your lawn by Friday afternoon.
UPDATE: Tue 8 Feb 2011 / 10:30 a.m.
Winter Storm Warnings are now posted for the entire area. Snow accumulations will vary considerably, and with the drifting expected it will be difficult to measure, but a range of 4-8" is reasonable based on the available moisture, speed of the system, and track of the trough's core.
All of this matches well with discussions posted here over the past few days.
Here's what you can expect:
- Rain changes to sleet and then to snow before sunrise Wednesday
- Periods of heavy snow especially 5am-noon Wednesday
- Near-blizzard conditions: travel is not recommended during the storm
- Snow tapers off during afternoon and ends completely by sunset
- Strong northerly winds of 25-35mph Wednesday
- Wind chills of -10 to -20 degrees Wednesday
- Air temperatures in the teens by sunset Wednesday
- Lows 2 to 8 degrees Thursday morning, 5 to 12 degrees Friday morning

UPDATE: Mon 7 Feb 2011 / 5:50p.m.
This is an update to my blog of last Friday entitled "Arctic Air and Snow Potential: Next Week".
There’s very little change to my initial suspicions from last week; we will endure the 3rd major winter storm of the month late Tuesday and Wednesday.
Here are the highlights:
Much colder air spilling in overnight Tuesday night and continuing Wednesday
Snowfall of 4-8” with higher totals possible under core passage of upper trough Wednesday
Wind chills to zero to -20 Wednesday afternoon/night
Blowing and drifting snow making travel very difficult Wednesday
Roads should partially melt off by Thursday afternoon if we get forecasted sunshine
All roads should be in good shape by late Friday morning
Warming trend this weekend as upper air pattern shifts: no further arctic outbreaks foreseen after this one for at least 10 days.
