The final week of February is upon us and for many that’s good news given the cold and snowy winter season thus far. Milder conditions recently have taken a bit of the sting away from the relentless winter weather but after Sunday we are marching right back into winter.
High pressure yields to an approaching disturbance later on Sunday. Although it will be another mild day temperatures are expected to be a few degrees cooler from the high readings of Saturday. Also, there will be more cloudiness as the disturbance approaches the Pioneer Valley. This system will not have a lot of moisture to work with so any precipitation that we do get is expected to be light. A few rain showers in the afternoon changing to a few snow showers at night as temperatures cool down. It is possible a few hours of steady light snow falls but even if it does we are looking at very little accumulation, if any. This is a fast moving system and will be out of here early Monday morning. High pressure expands eastward out of the Plains and allows for dry but cold conditions Monday and Tuesday.
The much cooler air begins to transfer into the region late Sunday night and more so on Monday and Monday night. This will be the beginning of what will be a progressively colder week. By the end of the work week we return to bitter cold arctic air as February comes to a close.
The colder air is not the only story this week. Another winter storm may threaten the area on Wednesday and with the colder air in place it will be a snow producer. Latest computer guidance is suggesting a closer track from earlier runs with a decent shot of a plowable snow event during Wednesday. This is not etched in stone by any means but it is beginning to look more likely than not that we do get some amount of snow Wednesday, it is just too early to be specific on this potential storm.
Once that storm passes by, whether it impacts us or not, some very cold arctic air will overspread the region late week and it appears we are in for a few days, especially nights, of icy cold weather once again.
