MADISON (WKOW) - This arctic air will be pushed aside quickly by milder Pacific air starting tomorrow.
The jet stream is made up of fast-moving winds in the upper levels of the atmosphere and divides air masses.
The jet dipped far south today allowing cold air to spill in from the Arctic. Temperatures ranged from the single digits this morning to the teens this afternoon, about 15 degrees below average.
Starting tomorrow and lasting through Christmas, the jet will buckle back north allowing a much milder trend.
Tonight temps stay steady in the mid-teens before climbing on Thursday.
Winds at ground level will shift from the south bringing in warmer air.
Highs Thursday afternoon will be in the mid 30s.
Clouds increase Friday, but it stays mild with highs approaching 40°.
The winter solstice is Saturday, but temps will feel more fall-like with a high in the mid 40s.
Highs in the upper 30s to mid 40s through Christmas Eve, and we remain dry.
On Christmas Day it appears there may be a storm system pushing in. A mix of rain and snow is possible in the afternoon. There is a lot of uncertainty though, so stay tuned!
