A cold front sank through the Hudson Valley overnight, and it’s ushering in some cooler temperatures, and some increasing wind…
Clouds will mix with sunshine as the wind increases out of the NW today. The wind will gust over 20mph at times today, and that will add a winter-like chill to the air. Temperatures will hold steady in the low to mid 40s for most of the day, not moving very much from where they are this morning. But as mentioned, that NW wind will make it feel quite a bit colder, with wind chills in the mid 30s for most of the day. Make sure you throw on a coat if you have outdoor plans today.
After a seasonably cold night tonight, Monday looks similar to today in many regards. We should have partly to mostly sunny skies, and we should continue to see a pesky NW wind around 10mph, that could gust over 20mph at times. Thank goodness the air mass isn’t truly arctic, or the next 48 hours would feel brutally cold. Instead, it’s just a typical late fall… early winter feel to the air. While chilly, this weather is not unlike what we would typically expect this time of year… just a few degrees below normal.
No major storm systems, or arctic cold on the horizon over the next 5 days. We’ve got a strong Greenland block setting up, which normally means a cold, stormy pattern for the eastern US.
Here is the jet stream pattern for Monday. The Hudson Valley is represented by the black star. Notice the white A at the top of the jet stream image. That represents a strong ridge over Greenland, also known as a negative North Atlantic Oscillation (-NAO). Often, this block prevents storms from going out to sea, and coastal storms are favored to develop. However, notice the black B over the eastern US. That’s a building eastern ridge, which forces the jet stream up into Canada… and the result is that despite the -NAO favoring a cold pattern in the Northeast… the building ridge forces that cold to remain up in Canada, instead of filtering into the eastern US. You can even notice on this image, how the cold is packed tightly up in Canada. For the next 1 to 2 weeks… we expect this to continue being the pattern. So don’t expect any prolonged cold outbreaks, or real chances for significant snow… as we push into the beginning of December.
However, if you’re looking for signs of winter… or are a snow lover… you shouldn’t have to wait too much longer…
Once we pass the 1st week of December, we start to see signs of major changes. A major trough could dip into the eastern US (B on map). We could also continue to see the block over Greenland give us a -NAO (A on map). Then we get the ridge building out west (C on map), which helps direct our flow out of northern Canada. If this pattern plays out… we’ll really see winter invade the Hudson Valley. But this map is over 10 days away… so we have a lot of time to see changes develop in the projected pattern.
For now… have a great Sunday… and thanks for all your support!
