Metro Boston, north shore and western suburbs: From near record cold temperatures to blizzard conditions we have seen a dramatic start to the weather in the first week of 2014. Over the next 24 to 30 hours or so, beginning Sunday morning, we are in for a bit of a thaw with rain in the forecast as well. Monday night into Tuesday and Tuesday night we plunge back into the deep freeze as another arctic front pays us a visit.
Low pressure is going to move through the Ohio Valley today and should be positioned along the eastern Great Lakes by Monday morning. From there it continues into southern Canada leaving us on the mild side of this system as milder air will stream northward ahead of the storm bringing us a brief respite from the very cold weather of late.
Precipitation will be slow to advance into northeastern Massachusetts today. It now appears that we get a fair amount of sunshine into midday before clouds begin to overtake the sky. We could see a spot shower or two later this afternoon but mostly it stays dry through the day. You will notice a nice recovery in temperatures as we move beyond the freezing level and combined with the sunshine there will be some melting. Through the interior temperatures will be several degrees cooler than along the coastal plain and this will play a significant part in the possibility of spotty freezing drizzle or rain late day into early tonight. As a result of this possibility the National Weather Service has issued a Freezing Rain Advisory for interior sections, mainly west of Route 128, which is in effect from 3 pm this afternoon until midnight.
After midnight the surge of milder air will make its presence felt and temperatures actually rise into the 40s, which in turn brings an end to the freezing rain threat. Rain showers continue into Monday morning so a wet commute to work or return to school can be expected. Showers continue through Monday morning, possibly with a few locally heavy downpours, becoming more spotty in the afternoon. The rain may change to a brief period of flurries or snow showers late day as a sharp cold front crosses the area early afternoon setting us up for more bone chilling cold Monday night.
On Tuesday the mercury won’t budge much at all, perhaps a few degrees, but that will be about it. A very cold and blustery day is in store as we will not move out of the teens for highs. It gets even colder Tuesday night with many of us back into the single digits.
Wednesday and Thursday brings generally fair skies as high pressure has a firm grip on the region. Temperatures will moderate as well but still remain slightly below normal.
Unsettled weather could arrive Thursday night or Friday in the form of light snow or snow showers.
