Make sure your scarf doesn’t end up here Thursday afternoon. You’ll need it.
If you like weather… let’s change that to love… if you love weather, Thursday will intrigue you. If you’re rarely amused by weather, Thursday’s probably isn’t going to be very entertaining to you.
Remember the Silly Silo (1975-2013) at Adventureland? You got to hang out and stick to the wall for a while… before the floor suddenly dropped below you. That’s kinda like Thursday’s weather!
Temperatures typically go up during the day and then back down at night after the sun has set. When does that rule change? It can change with something called advection — the moving of air from another location to here. You can have warm air advection or cold air advection, for example. In the case of Thursday, a storm will cause our south winds of 15 to 20 miles per hour to change briefly to the west for a couple hours around midday and then to the northwest at 20 to 30 miles per hour.
As those northwest winds continue to blow hard Thursday afternoon and Thursday night, we get deeper and deeper into the ‘train’ of air going northwestward to the northern part of the U.S. and into Canada. We tap into that and end up with their weather. It’ll take us very abruptly from enjoying warm air advection to shivering in very blustery cold air advection.
Temperatures will start the day around 50 degrees and tumble significantly from there. You’ll notice the most rapid drop from 11:00am to 3:00pm. This is what I think temperatures Thursday will be like:
What else is going on for Thursday?
Aside from the wild temperature swing, I think Thursday will be cloudy with some light rain showers during the mild morning. I think gusty winds will then be able to evaporate most of the water off the pavement before subfreezing temperatures hit after 1 o’clock. There could be a few snowflakes flying in some spots in the afternoon, but I think the timing and combinations of moisture vs. temperature vs. wind will not be favorable to ice or snow accumulation.
