I am away in NYC for the week. I will try to update when I can. Thanks!
Well, the cold weather has arrived. I hope everyone has their heavy coats, gloves, and scarves on hand. Low temperatures in the coming days will fall into the teens over just about our entire region. Single digits are not out of the question in areas that recently received snowfall - to our north and east. Decent cold for December.
The Louisville, Kentucky NWS put this map out last night - showing some of the snowfall reports. The map below can be enlarged by clicking on it.
For those of you that are desperately looking for snow - you will have to wait a bit longer. I don't see a significant chance for snow in our local counties for the near term. I will be watching a system for next weekend - but that is still several days away. There could be another clipper to watch - the GFS likes the idea - the ensembles are iffy on any forecast for snow. However, we will continue to watch. The EC (another model of choice) shows a southern system that we should keep an eye on it.
Let's take a look at today's snowfall probability map. This map shows you were 1" or greater may fall (see the probabilities to the left side of the map). Click for larger view.
Bottom line - I am not bullish, at this time, on any significant event for the near term.
The big weather story over the coming days will be the cold temperatures. I will post a few maps below. The maps are from www.wright-weather.com - my favorite site for model data. These cold temperatures will be a bit of a shell shock for some - however, it is nothing unusual or out of the ordinary. We have experienced lows in the teens in the past during the month of December.
The December forecast for cold is getting off to a nice start. We will see if it lasts. The first half of the month looks like we will average below normal. There will be some warmer days mixed in.
The above map is showing Tuesday morning low temperatures. Click for a larger view. As you can see - widespread cold across the nation. Brrr - best fits the description.
Now let's check the map below - high temperatures for Tuesday afternoon. Still cold across much of the United States.
The above map is showing the low temperatures for Wednesday morning. Another cold morning across the United States.
Then we look way out in the future to December 14th. Of course we don't trust the model this far out - however, you get the general idea that it still appears to be leaning towards the cold side. We will wait and see if this verifies.
The above map is zoomed in on our region. Low temperatures Tuesday morning. Ohio Valley will be shivering. So - bundle up and prepare for some cold days ahead of us.
The above map is the NAM forecast low temperatures - you can see bitterly cold air invading the Ohio Valley. This map is for Wednesday morning.
The general pattern favors cold temperatures for the most part. Some brief warm ups. So - for now - we will ride that train. When we start to shift back in the other direction then we will catch up to the trends early enough to jump off the cold train.
Speaking of jumping off the cold train - the above map shows the departure for maximum temperatures on Thursday. Look out to the west - you can see warm temperatures are starting to build back north and east out of the central plains. Most of the eastern half of the United States remains colder than normal.
The map above shows next Sunday. The GFS is sniffing out a snow maker for the Ohio Valley. Too far out to bite our teeth into this solution. Just something I will be watching. Stay tuned for updates. One of these days we will have snow again!
