Good Monday everyone and welcome to a new week that will feature more of the same from Old Man Winter. We have a potential storm lurking for the end of the week that should deliver snow to our region once again. The big question is… how much? That is something we should have a better idea on later today into Tuesday. Whether it’s a few inches or several inches… it’s more of the same with a lot of blog updates coming your way this week.

Before we get to the end of the week action… we have a taste of wintry weather to go through over the next few days. Low pressure is dropping southeastward into the Great Lakes later Today… this will slowly drag a front toward the region into Tuesday. A few showers will increase out there today… especially into the west. These showers would then increase tonight into Tuesday.  Tuesday will find a big storm developing along the east coast and rolling northward. The front moving in from the west develops a weak wave of low pressure along it by Tuesday afternoon and evening. Much colder air will wrap in behind this system as it moves across Ohio and should change our rain over to a period of light snow from west to east. This can put down some light accumulations.

The GFS Ensembles seem to be handling this situation well…



Temps today will warm into the mid and upper 30s in the north to the 40s across the south. Temps Tuesday will be near 40 before the cold air crashes in late in the day.

This brings us to the potential winter storm across the eastern half of the country from Thursday into the start of the coming weekend. A major push of arctic air will be diving southward out of Canada late Wednesday into Thursday. This happens as a significant disturbance pulls northeastward out of the desert southwest spawning low pressure ahead of it. The possibility for the northern branch of the jet stream to phase with the energy moving in from the southwest is a possibility. If that happens… look out. That would crank up a major snowstorm from the the midwest through the Ohio Valley into then into the mid atlantic states and northeast.Again… IF.

That is only one possibility as of now and it’s a long way from being set in stone. The Canadian Model is going crazy with the phase and ensuing storm…



That is the most extreme of the models right now… but the GFS Ensembles mean is certainly hinting that the Canadian may be sniffing something out…



The operation run of the GFS continues to go back and forth with how to handle the two branches of the jet. The latest run of the model says we do not get these streams to phase and we are then left with a nice little 2″-4″ snowfall instead…


While this is not the best pattern for the GFS… what it is showing above is a possibility I outlined a few days ago. In the camp of the “non phased” GFS is the latest run of the European model, which shows a similar snowfall of 2″-4″ for our region late Thursday into Friday. It wouldn’t take much correction on either model for them to show something similar to the Canadian.

I am still not comfortable in an upgrade and will stay the course until we can be fully determine if the storm will phase or not. Either way… another round of accumulating snow is likely heading our way later this week.

I will have updates through the day so keep checking back. Have a great Monday and take care.
