With no hurricanes currently active in the Atlantic, today’s weather description will focus on New England’s current weather. For the next couple days, there will continue to be cloudy, rainy weather. Last night there was the unusual occurrence of temperatures rising overnight; a consequence of a warm frontal passage. This frontal passage is responsible for the warm, humid weather today, with a chance of showers throughout the day. With rain that could be heavy at times as well as strong winds, it will certainly not be the nicest of weather. Tomorrow will also be cloudy with a slight chance of showers, especially in the evening. By Thursday, a strong low pressure system is forecast to track into the Northeast, bringing tropical moisture with it, although there is still uncertainty in the timing. The combination of high levels of precipitable water and lift means that there is the potential for heavy rain and urban flooding from Wednesday night to Friday morning.

The active hurricane season continues in the Atlantic, with three hurricanes occurring simultaneously (a fairly rare occurrence in the Atlantic). As of 5 p.m. yesterday, Igor had sustained winds of 125 mph, Julia had sustained winds of 85 mph, and Karl had sustained winds of 80 mph. Igor has maintained its Category 4 intensity for several days, and is expected to continue to be a powerful hurricane before gradually weakening as he moves over colder waters while curving towards Bermuda. Julia was a Category 4 hurricane on Wednesday, before weakening due to less favorable environmental conditions, including interaction with Igor’s outflow, and is forecast to continue to dissipate. Neither Igor nor Julia forecasted tracks indicate that they will impact the U.S. Karl actually intensified to hurricane status after making landfall in Belize as a tropical storm and crossing over the Yucatan peninsula into the Gulf of Mexico, and is expected to make a second landfall in eastern Mexico this afternoon.

After five straight days sunny skies with temperatures greater than 90°F, today Cambridge will experience a different type of summer weather phenomenon; a hurricane. Hurricane Earl, which has been churning in the Atlantic for the last week, had an intensity of 115 mph and was located 670 miles south/southwest of Nantucket (off the coast of North Carolina). The hurricane is predicted to pass about 60 miles east of Chatham, MA (on Cape Cod) Friday night, and although it will have weakened due to the colder ocean waters, it should still pack some powerful winds. Cape Cod may experience winds of up to 80 mph, stormy seas with wave heights of 20 feet, as well as heavy rain. Here in Cambridge, further from the center of the storm, we should expect heavy rainfall this evening through early tomorrow morning and winds of up to 40 mph (tropical storm strength), with the possibility of stronger gusts. The rest of the holiday weekend should be sunny with milder temperatures.

Wednesday’s storm was a major disappointment for those hoping for significant snow accumulations here in Cambridge. While the storm dumped around a foot of snow along the I-95 corridor from Washington D.C. to New York City, it remained stalled off the Long Island coast for most of the day on Wednesday. We therefore only experienced light snow and some drizzly rain; Logan Airport recorded 1.2” of snow. It appears that warm air advection wrapping around the storm allowed the temperatures to increase enough to prevent significant snow accumulation in Eastern Massachusetts.

There was active winter weather over the holiday season in the Boston area, with two major snowstorms occurring over the last two and a half weeks. After a snowy start to the new year this past weekend, this week will be decidedly quieter. There will be relatively clear skies today and tomorrow. Temperatures will continue to be slightly below normal, with high temperatures around freezing (32°F, 0°C) both today and tomorrow. A shortwave trough will move over New England on Friday, bringing snow showers to the region. Light accumulation is possible. The shortwave will also intensify a coastal low pressure system, which should pass well to our southeast, and not have much of an impact in Cambridge. Over the weekend, an arctic air mass will move in behind the shortwave that passed through on Friday. Skies will be mostly sunny with colder temperatures and moderate (10–15 mph) winds from the northwest. Calm weather is expected to continue into early next week.

Hopefully everyone enjoyed the warm sunny day we had yesterday, because this weekend brings a return to more seasonable conditions. The preliminary climate report from the National Weather Service indicates that yesterdays recorded high temperature of 69°F at Logan Airport was a whopping 23°F above normal. It broke the previous record for December 3, which was 65°F set back in 1932.

Thanksgiving is just a few days away, which means that winter is on the horizon. Thanks to El Niño, the National Weather Service is predicting a warmer-than-average winter across much of the western and central US, but a cooler-than-average winter across the Southeast and Mid-Atlantic.

The past week has been a terrific example of how variable fall weather can be. While last weekend was cold and rainy (and even a bit snowy on Sunday!), the last few days have been warm and sunny. This variability continues over the next couple of days. Today should be significantly cooler than the past couple days. The temperature will only make it to around 50°F, and brisk winds from the north mean it will feel even cooler. The next low pressure system will move into our area late tonight.

Fall is officially here! There are several ways one may have noticed that the seasons changed. First of all, Halloween merchandise is all over the stores (time to start planning your costume). Yesterday’s cool temperatures were another hint, a trend that will continue today. Finally, this weekend is the “Great Glass Pumpkin Patch,” in which the MIT Glass Lab displays and sells over 1,000 handblown glass pumpkins. Unfortunately, the weather may not cooperate this weekend and we may have a wet and rainy pumpkin patch.
