One more day of arctic cold
Going by today's temp/dewpoint/pressure/wind graphs, it appears the latest arctic front passed Black Cat around 8:00 this morning. Just a trace of snow fell from the snow squall. Prior to the frontal passage temps reached their lowest level of the winter once again, this time bottoming out at -9. While the air warmed a bit during the actual frontal passage, the cold air behind it is now working its way in. The dewpoint is once again retreating back to the -20 level. Winds have picked up quickly during the morning hours and gusts are nearing the 40 mph mark for the second time this week.
Looks like a pattern change this weekend. Since late January the upper level winds have put us in the path of air coming right down from the Yukon and James Bay Canada. Beginning Saturday, just in time for the new (early) Daylight Saving Time, it looks like the pattern will become more zonal (straight west to east) across the northernmost US States. That usually favors normal temps or even slightly above normal... and any storms on that track are usually moisture-starved and hauling right along.
With the 90+ air beginning to show itself in the SW desert and the arctic cold still nearby, it could make for some interesting battles in the month ahead.
