October has arrived, and temperatures should be starting to get cooler. September certainly ended on a cool note and the first day of October was on the cool side as well. However, we’re going to warm back up this week, so the cool shot was short-lived.
High pressure will be in control of the region’s weather for the next few days. Although the week will start off cool, a warming trend is expected as high pressure moves offshore. A cold front will approach the region on Thursday. The front will take its time moving through the region, but it also won’t have a lot of moisture to work with. As a result, Thursday will be another warm day, but only a chance for a few showers or maybe even a thunderstorm. The question is: how many people will notice the weather on Thursday with Red Sox/Astros Game 1 at 4pm, the Bruins season opener at the Garden against Nashville at 7pm, and the Patriots in Tampa at 8:25pm? Friday will likely be another mild day before the front finally pushes through, with cooler conditions settling in behind it for Friday night.
Once that front moves through, it is going to stall out south of New England. How far south it stalls will play a big role in determining Saturday’s weather, as a couple of waves of low pressure will likely ride along that front. If it stalls close to the south coast, Saturday could be cool and rather wet. If it stalls out farther to the south, Saturday may see some sunshine develop. It looks like the front moves back northward as a warm front on Sunday, with some rainfall likely. How quickly it comes back will determine our temperatures (and to a lesser extent our weather) on Sunday. If it takes its time coming through, temperatures could stay in the 50s and lower 60s all day with rain likely. If it comes through quickly, we could jump into the 70s with just some showers or even a thunderstorm. Once it does come through, it looks like the first part of next week will be warm but probably also wet. It also looks like a cooler pattern may try to develop towards the latter half of next week as well. Whether this is temporary or the true start of fall remains to be seen.

Monday night: Clear skies. Low 44-51, except some of the normally cooler locations could drop into the upper 30s to lower 40s.
Tuesday: Mostly sunny. High 64-71.
Tuesday night: Clear to partly cloudy. Low 47-54.
Wednesday: Plenty of sunshine, breezy, and warm. High 73-80.
Thursday: More clouds than sun, chance for a few showers. High 75-82.
Friday: A mix of sun and clouds. High 69-76.
Saturday: Partly sunny and breezy, chance for a few showers. High 62-69.
Sunday: Partly to mostly cloudy with more showers possible. High 65-72.
While our weather is quiet, a much different story is expected from the Plains into the Rockies. A storm system will produce strong to severe thunderstorms across the Plains states today, with some heavy rain spreading into the Upper Midwest. Behind the system, snow is expected across much of the Intermountain West. Across the higher elevations, snowfall totals of 1-2 feet or more are possible.
