Long-Range Forecast – October 9

The hallmark of the next 10-15 days will be a slow-moving weather pattern. After a storm scoots out to sea south of Southern New England bringing chilly showers on Saturday, there will be three mainly dry days into the middle of next week. Eventually, another storm system will move into the Northeast and showers and thunderstorms are possibly Wednesday and/or Thursday of next week. The rain could be heavy at times depending on the exact track of the storm.

More dry weather is likely at the end of next workweek, and through next weekend. We’re still keeping our eye out for a brief cold shot around October 20. In this pattern, we also need to watch for storms to develop near the Southeastern United States and move north. There are signs that could happen in the last ten days of October.

Much of Southeastern New England remains in a moderate drought, but that may be short-lived with a couple of rain events ahead, and already a decent amount of rain so far this month.

Long-Range Forecast – October 6

October is off to a rainier start than September, and that is good news for drought-parched Southern New England. There is more rain in the forecast for the middle of this week before about 48 hours of dry weather from Wednesday afternoon into Friday. Another front will head for Southern New England and bring more showers on Friday. Right now, it looks like that front will settle south of our area for most of the Columbus Day weekend. I’m a little leery of the front drifting north or a wave of low pressure forming along the front and delivering another round of showers sometime between Saturday and Monday. It will be a seasonably cool weekend, with highs in the low 60s.

There is a decent amount of uncertainty with next week’s forecast. The pattern looks fairly slow-moving, and it’s unclear how far east a storm system will get in the middle of the week. The latest indications are that it may be west of Southern New England for a while, but that is just a trend. There will also be a disturbance in the Atlantic Ocean that could bear watching if it drifts northwest to off the Carolina coast. Once again, it looks like the best chance of showers is in the midweek.

Both the GFS and European model are hinting at a cold shot around October 20. It does not look like it will last long, but it may be the one that puts an end to the growing season in most of Southern New England. It’s that time of the year!

Long-Range Forecast – October 2

It looks like we’ll continue to come out of a dry stretch of weather with rain or shower threats every few days for the next couple of weeks. Showers are likely on Saturday, primarily in the afternoon and evening. Sunday through Tuesday looks dry before another front brings rain in the middle of next week. There may be a third front in the next 10 days coming through on Columbus Day weekend. I’m not as convinced that we’ll see steady rain from that one. We’ll have to keep an eye on the tropical system in the Eastern Pacific Ocean, and where it’s remnants move through the Southwest US.

The overall pattern is not super exciting temperature-wise. Most days will be near normal, and nights will probably average above normal in the next two weeks. It does not look like we have any early blasts of very cold weather heading our way. The tropics also continue looking sleep in the Atlantic and Gulf of Mexico.

Long-Range Forecast – September 29

A northeast wind will prevail for most of the rest of the workweek in Southern New England. That will keep it relatively cool during the day, and relatively mild at night because of cloud cover and the ocean temperature still in the 60s. There should be a roughly 10 degree temperature range from night to day Tuesday through Thursday.

Friday looks like a decent day with highs and lows close to normal for early October. A cold front will move through on Saturday bringing showers and possibly thunderstorms. Right now, it looks like the rain will be steadier in the morning than in the afternoon, but that timing could change. Sunday into Monday should be dry before another weak system moves through the Great Lakes and brings the possibility of showers in the middle of next week.

The active northern branch of the jet stream should carry another system through late next workweek. Once again, it does not look like a soaker, just the chance of showers. The pattern will stay active through Columbus Day weekend. Although it will be warmer than normal over the next two weeks, I don’t expect anything close to the summer-like warmth we had this weekend. Most of the “warmth” in the next two weeks may actually come at night when temperatures run several degrees above normal.

Long-Range Forecast – September 26

Thursday’s rain storm was close but not close enough for most of Southern New England. Cape Cod and Nantucket received 1-2″ of rain, but the totals were paltry for most areas west of the Cape Cod Canal, including all of Rhode Island. Dry and warm weather is likely through the weekend into early next week, and our next shot at rain is in the middle of next week as another storm develops along or off the Eastern Seaboard. The jury is out on how close the storm will come and whether we’ll get beneficial rain, but the potential exists for at least showers from Tuesday-Thursday of next week. In any event, the temperature will go from well above normal to near/below normal Tuesday through Thursday. It should moderate to near or above normal next weekend.

Another system will move through the Northeast late next weekend, and that one could bring showers.You may remember there was a moderate drought last fall before heavy rain in late November ended it. In general, the pattern looks fairly active in the Eastern United States in early October, and that should give us possible rain every few days. It does not look like it will be terribly cold at any point through the first 10 days of October.

Rain Likely on Thursday in RI and SE MA

A developing storm system that we have been watching closely over the past couple of days will likely come close enough to bring steady rain to Southeastern New England on Thursday. The storm is developing along the Southeastern United States coast and it will creep up the coast on Wednesday before arriving with rain late Wednesday night and Thursday.

Wednesday should be a decent day, with some sunshine followed by increasing clouds, and highs near 70 after a morning low temperature in the 40s. Clouds will thicken Wednesday night, and rain is possible, especially near the coast, by early Thursday morning. Lows will be in the 50s. Thursday looks rainy with highs only in the low 60s. There will be a 10-15 mph east-northeast breeze as the storm moves south of Block Island. Showers will likely continue Thursday night into early Friday before the storm drifts out to sea. Lows will be in the 50s Thursday night. If the storm tracks close enough to the coast, then more than a half-inch of rain is likely – a welcome soaking and about as much rain as many places have seen so far this month. Lighter showers are likely in Northern Massachusetts and Southern New Hampshire.

After a murky start, the sky should brighten Friday afternoon. It will be seasonable with highs in the upper 60s to low 70s. The best chance of sunshine is away from the coast. It still looks like there will be plenty of sunshine and rather warm conditions this weekend. Both Saturday and Sunday should be mainly clear with highs in the upper 70s to low 80s inland, and low 70s near the coast. Lows will be in the 50s.

Long-Range Forecast – September 22

A few measly showers on Sunday brought the rain total for the month to just over a half-inch in the Providence area. If there is no rain for the rest of the month, which is possible, then this will be the second driest September on record, trailing only 1914 when there was 0.48″ for the month. It looks like there are two shots at rain during the rest of September. First, we’ll keep an eye on a system that develops along the Southeast Coast and drifts north late in the workweek. Right now, it looks like it stays just offshore, but the system that brought rain on Sunday also looked like it was going to stay away. These systems have a tendency to drift closer to the coast than what the models predict a few days out.

Overall, the pattern will be warmer than normal for the rest of the month and early October. The dry and pleasant weather through the middle of this week is actually pretty close to normal (70°/50°) for this time of the year.

The next best chance of rain is in the middle of next week when a system may move out of the Southeastern United States and up the Appalachians. It’s 8-9 days away, but the European model has hinted at it for a few days. The GFS model keeps the Northeast dry through most of next week, too. Both the GFS and European have a cold front moving through the Northeast with showers sometime between October 3-5.

The tropics remain unusually quiet and there are no strong signs that anything significant will develop in the next two weeks.

Long-Range Forecast – September 18

This September is well on its way to being among the driest on record in Southern New England. There has only been 0.54″ of precipitation in the Providence area, and that’s just a hair above the record low total for the month – 0.48″ in 1914. Of course, there are still nearly two weeks left in the month, but, most of the time it looks like dry weather will continue.

Our next shot at some rain is late in the weekend, but it looks like an offshore storm and approaching cold front will not get together, and the weather will be mainly dry except for scattered showers Sunday night as the cold front passes.

Most or all of next week will be dry. A huge area of high pressure will set up shop in the Northeastern United States, and fair weather is likely from Monday into next weekend. It will be seasonably cool early in the week, and then get warmer than normal late in the week. Of course, 70° is warmer than normal in late September, so we’re not necessarily talking about a heat wave!

We will continue to watch the Gulf of Mexico and off the Southeast coast for anything tropical next week into the early October. Some models are hinting at developing tropical systems in the 10-15 day range.

Long-Range Forecast – September 15

The temperature is running 3° above normal in the Providence area at the midway point of the month. The very warm first week outweighed the much cooler second week. The average monthly temperature will continue drifting back to near normal as more cool weather is ahead for the next five days.

Aside from a few stray showers on Tuesday, there is not much rain in the forecast through the weekend. A stray shower may pop up on Thursday as a cold front moves through, but that should be the exception and not the rule. A very early frost cannot be ruled out in the interior countryside of SE MA and N RI late this week. The weather should warm up by late in the weekend.

A cold front will move through early next week. Once again, it does not look like more than scattered showers at this point. More dry weather is likely in the middle of next week. Looking way down the road, there is a chance that one of these fronts taps into some tropical moisture in the Gulf of Mexico and brings a more significant rainmaker up the East Coast. The timeframe for that possibility is in the last week of September.

Long-Range Forecast – September 11

The second week of September has not been as warm as the first, but it’s still running a bit warmer than normal, and the month is averaging 5.5° warmer than normal in the Providence area through the first 11 days. That’s not unexpected considering how we saw the pattern changing near the end of August.

While the temperature pattern has been fairly straightforward, the rain forecasts have been difficult. Basically, by Saturday, there will have been just 0.6″ of rain in the Providence area in the past month. There have been a few shower chances that did not materialize, including this evening as a front is moving through without generating rain. The phrase “when in a drought, forecast dry” is pinging around in my head as I look at the outlook for the next couple of weeks. Right now, it looks like a decent chance of 0.1-0.25″ of rain late Saturday afternoon and/or evening and on Tuesday – primarily in the morning. We’ll see if those odds decrease as the even nears – similar to what happened tonight. Other than that, rain seems unlikely in the next 10 days.

One thing we’ll be keeping an eye on is the potential for tropical or hybrid systems to develop near the Eastern Seaboard in the 10-20 day range. A tropical or hybrid system could infuse some moisture into a cold front and bring much needed rain.
