SUB-ZERO TEMPS ON HOLD FOR NOW
The arctic air is easing. Brace for more cold temperatures Wednesday night, but we will not go below zero.
We've been sub-zero nine times already this season. That is the most to date for so early on in a season since 1990. Checking weather records, 1990 ended with only nine sub-zero lows, so could that bode well for us?
We are losing the connection to the polar branch of the jet stream and a second January thaw is getting underway. As the jet stream flattens, the temperatures will rise. We are forecasting temps near 50-degrees this weekend.
I'm posting below the changes in the upper air pattern from Wednesday to Saturday. Note the colder colors retreating north.
