Interpreting wx radar after color inflation:
green = partly cloudy,
dark green = cloudy,
yellow = virga,
orange = sprinkles,
red = moderate sprinkles,
purple = light rain,
blinking dark purple = rain,
radar inoperative = rain, sometimes moderate
Come out, Virginia, don't let me wait
You snow-holic girls start much too late
Aw, but sooner or later, it comes down to fate
This might as well be the one
You must be new here, Kay. The rules here require rooting for the imby jack, then suicide when, surprise, that does not happen. Lather rinse repeat.
I'll be happy if the rest of the month features interesting weather, but I'm just a renegade rules breaker.
If this temp pattern is anything but random, I would speculate it is related to the winter solstice. Minimum northern sunshine happens mid-late December. Perhaps the small increase in heating that occur in January is enough to instigate artic cold draining to the lower latutudes at a certain time, with the result DC sees unusually cold temps Jan 20 or so.
Long term temperature normals are a smoothed average. If you remove the smoothing, that is, examine the actual daily averages for the past 50 years in the NE Corridor, you'll find the there are two separate annual min temps, one centered around Jan 20 and another Feb 5. In between those dates is a slight warm up, sometimes called the January thaw. This year might follow that pattern.
Southern slider. The 12z GFS appears about as good as we can get from it around here. If the storm were to wrap up more than depicted, precip type issues would crop up for the big cities. Been following the 11th's storm for two weeks, sorry it's not looking wow for us.
I've had my eye on Jan 10-12 since posting here two weeks ago. Love fairly slow moving systems like it. Someone's going to cash in, but the big cities now look to have mixing concerns. The Jan 5-6 Thing should clear the way for better 10-12th modeling.
My Heathkit ID4001 station from the 70s is still working, anemometer and all. Probably going to outlive me. Whether its air temp sensor ever reports below zero again is another matter. At least there's a chance next month.
