The much advertised warm spell is in the process of doing its dirty work, and it’s being assisted by a period of rain overnight that will last into tomorrow, before taping off by afternoon. In one of our first forecasts on the new site we posted a blog titled Snowpack Crusher (can be found in archived forecasts), about the upcoming warm spell and rain, any guess on how much of a beating our snowpack has taken? Let us show you, below is two images of the European Model, both depict snow depth across the region, one before our warmup and one after.
As you can see, this is certainly a snowpack crusher, and not a good sign for anyone hoping for a white christmas, although some dirty snow in places will survive. The snow melt won’t be the only extreme that occurs, as our temperatures are also going to drop quite significantly behind a cold front that should clear the region on Monday, and allow colder air to filter back into the region by Christmas Eve. Just how much will the temps change over the next few days ? Below are two images from the NAM model showing just how much temps are expected to drop in about 24 hours across the HV.
Like we said, it will be a much different start to next week, when compared to how it ended, we still have a few days of rain to get though, but once the cold front arrives these warm temps will be a distant memory, so enjoy. Tomorrow we take a look at the potential for us to return to a stormy pattern to start January, so stay tuned!
