DAYS 1-5 (OCTOBER 28 – NOVEMBER 1)
November has made it into the 5-day forecast! And when we get there, it’ll feel like it! In fact, it’ll start to feel a bit like that even before we get there. But let’s not get too far ahead of ourselves. Before that happens, we have one more feel-of-summer days to enjoy today. This is the day that Boston can top a record high, because today’s is a few degrees lower than the previous couple that they fell shy of. A high of 82 at Logan today will establish a new record, and I figure they may get close at least, likely tie it, and possibly break it. The chance goes up as a west wind picks up speed and helps enhance the down slope effect which warms the air heading from the hills to the coastal plain. We’ll see how it goes. Otherwise our warmer than normal day will be punctuated by plenty of sun, but later in the day you’ll notice some clouds heading across the sky from west northwest to east southeast, and a couple of these, particularly in southern NH and/or northern MA, may produce a few light rain showers, albeit brief wherever they may occur. This is a cold front, and it opens the door to a different feel. Considering today’s high temps around 80 for many, after that front goes by tonight we’ll see quite the temperature fall as many areas land in the 40s by morning. And Sunday, we don’t see a whole lot of temperature recovery, so my previous overly-optimistic temperature forecast will have to be adjusted quite a bit. Sorry! And once the cool air is in, it’s hanging around for a while. We also have a wave of low pressure to come along the front after it goes by, and brings us some wet weather later Sunday through Monday. Initially the rain will struggle to overcome some dry air so a good portion of Sunday will stay rain-free, with just patches of light rain moving into the region during the afternoon. A more saturated atmosphere Sunday night and Monday will allow for occasional to frequent periods of rainfall, which will taper off later Monday as the low pressure wave starts to move beyond the region. This will allow dry weather to return for Tuesday – Halloween – but with the arrival of a reinforcing shot of polar air, it’s going to be a chilly trick-or-treat on Tuesday evening. We’ll already be watching another wave of low pressure moving up along the front that still sits not far to the south, so while I do think any precipitation will hold off for All Hallow’s Eve activities, the overnight hours into Wednesday look overcast and wet with more rain, and it can be cold enough for some mix/frozen precipitation to occur for a period of time over interior higher elevations – just a little memo from mother nature about winter drawing closer. Either way, with that system around, the high temps Wednesday will feel more like late November rather than the first of the month.

A weak weather system coming through early in the period with some unsettled weather, then a return to dry weather and a cool-down followed by another warm-up.
