A cold and blustery day is on tap for Monday. Temperatures are not very cold right now, but the problem is they are not going to budge during the day. There is an arctic front that passed through the area overnight and the reason you may have to brush off some new snow from your car.

If you are going to be outside for an extended period of time you will want to bundle up as the wind chills will also be a factor today, as that gusty northwest wind makes it feel colder than it actually is.

I'll be updating the snow forecast as it changes on Twitter at @growingwisdom Please follow me there. Feel free to comment or ask questions too.

More snow
There will be another system affecting the area Tuesday afternoon and night. A low pressure area will dive south from Canada and then reignite off our coast. These types of systems can produce a few to several inches of snow and although not a big storm, this has the potential to really foul up the Tuesday afternoon commute.

Tonight is going to be quite cold with lows ranging from the lower 20s around Chatham to 6 or 7 over northern Worcester County. (see map below of Tuesday AM temps) The full moon will light up the landscape, especially the first part of the night. The moon is called the “cold moon” this month; I don’t think you need me to explain why.

Conflicting models
The situation we are facing Tuesday is a tough one for our computer models. They notoriously don’t do well with these types of systems because the pieces of energy caught in the jet stream are difficult for them. Two models are seeing two pieces of energy growing two areas of snow, one Tuesday morning and a second, after a bit of a lull Tuesday night. The snow would be over early Wednesday morning. Two other models are keeping the energy weaker and as one piece that moves through Tuesday afternoon and ends during the commute home. The discrepancy would mean several more inches of snow over northeastern MA added to the general light snowfall to the south. I’ll have a better handle of this later today. The map below indicates my current thinking. Since all the models are forecasting some snow, the homebound commute is going to be a problem Tuesday.

Cold midweek, but milder finish
The deep freeze continues into Wednesday when highs will still stay in the upper 20s to near freezing. The good news, temperatures will warm towards and into the 30s for Thursday and some areas over the Cape could even see 40F. This time of the year the sun is very weak and the only way we really melt snow quickly is with a mild rain. Friday is even milder with highs well into the 40s for some real melting, at least on driveways, walkways and south facing areas. For those of you already tired of this winter, you may have to wait a bit to see bare ground or take a trip to the Cape for some winter golf.

Weekend garden tip
The video is from a few years back, but the tips on caring for a living Christmas tree are the same. Enjoy.
