about an hour ago: Severe weather operations are underway!

We're monitoring the storms heading through northern New England and central New York, which will reach southwest New Hampshire, western Massachusetts, & northwest Connecticut after 5 pm. Some of these storms may produce damaging winds & hail.

Storms may threaten central and eastern Massachusetts, the rest of northern Connecticut, and Rhode Island after 7 or 8 pm but the severe weather threat is more limited.

Stay up to date on the weather, and remember to head indoors if thunderstorms approach!

2 hours ago: Here's more information on the severe weather potential later this afternoon and early tonight.
facebookImage2_1.jpg
2 hours ago: Severe Thunderstorm Watch in effect for northern & western New England until 10 pm EDT.

Potential for damaging winds as the line of storms heads east.
3 hours ago: Heads up! Storms are starting to develop across northern New England.

5 hours ago: Are you ready for the "Late Show?"

It looks like thunderstorms will develop a bit later than what we usually see during the summer, more like after 4 or 5 pm in western New England, and later than that farther to the east.

The images below are from a high-resolution computer model and show what the radar might look like later this afternoon and early tonight. While the timing is probably off by a couple of hours, it shows most of the activity holding off until this evening.

It would be a good idea to stay updated on the weather today, especially if you are in western and northern New England where the potential for severe thunderstorms is highest.

7 hours ago: Since there is a potential for strong to severe thunderstorms late this afternoon and into this evening, it's a good time to review the criteria that makes a storm "Severe". Check it out and pass it along.

It is also a good time to have back-up plans in case you are planning on being outdoors today especially across southern NH, northern CT, and across western and central MA. Remember when thunder roars, go indoors.

12 hours ago: Today will be another day that proves this is summer. As is shown in the image, we are expecting maximum afternoon temperatures in the mid 80s to lower 90sexcept a little cooler near the water such as on Cape Cod. The humidity will be quite noticeable with dew points in the mid 60s to lower 70s. Dew points in the 70s are associated with oppressive humidity. Find ways to stay cool today.

An approaching cold front will set off showers and thunderstorms this afternoon. These showers and storms could produce strong wind gusts and heavy downpours.
Yesterday: Latest thoughts on potentially strong to severe thunderstorms late Wednesday afternoon and evening to the northwest of I-95. Please share with your friends and family.
facebookImage8_1.jpg
Yesterday: A few severe thunderstorms possible late Wednesday afternoon and evening to the Northwest of I-95. Highest risk in Northwest MA and Southern NH. Heavy rain and a very localized flash flood threat is also possible.

Yesterday: A very warm day in progress with afternoon high temps expected to top out between 85 and 90, except cooler on the immediate coast. Dry weather continues except for a very low risk of a spot shower/thunderstorms late this afternoon across interior Southern New England.

Yesterday: Anyone remember what they were doing 3 years ago today? Hopefully the day was spent inside or at the beach. Hartford, Boston and Providence all exceeded 100 degrees. Hartford set their all time record of high 103 degrees. Boston also hit 103 degrees, falling one degree short of their all time record high of 104, set way back in 1911.

Yesterday: A line of thunderstorms moved across North Dakota and Minnesota last night. There were several reports of downed trees, and one report of 2-inch diameter hail.

The cold front that caused this weather will move across the Great Lakes today and swing across Southern New England Wednesday night. This will bring us showers and thunderstorms. Some of the thunderstorms may produce strong wind gusts as well as heavy downpours.

Here is an image from the Duluth Minnesota radar from early this morning. It shows the line of thunderstorms that caused the damaging weather moving east into Upper Michigan and Wisconsin.
July 21: We are expecting active weather to return by Wednesday night. Here is a glimpse into the forecast for the next few days.
July 21: Although temperatures may still be a bit below normal today, they will increase tomorrow and again on Wednesday. The humidity climbs as well:
July 20: The showers across SE MA and E RI are likely to linger much of the night. Rainfall rates are light, but due to their slow movement a quarter inch or more of total rainfall is possible:
July 20: [9 am] MORNING UPDATE:

Analysis shows a stalled frontal boundary south of our region becoming the focus for continued showery weather across southern and eastern portions of New England much of today.

Drier air within the low-levels may hamper rain from reaching the surface (note the separation of the red [temperature] and green [dewpoint] line within the observed sounding over Chatham this morning).

Otherwise mostly cloudy conditions will make for a cool day, more so along the east-facing shorelines with a brisk onshore wind.

July 20: A few showers this morning, some early day cloud cover, and winds off the ocean will lead to another day where highs remain below normal:
July 19: Some sprinkles will be possible tonight and Sunday along southeast MA and RI, with brief showers possible on the Cape and Islands. Otherwise partly cloudy skies are expected over the interior tonight and Sunday, with mostly cloudy skies closer to the coast.
July 19: Low humidity remains a constant for the weekend. However temperatures will be a bit warmer today, with more sunshine:

July 17: Hurricanes aren't just powerful gusts of wind – they can produce dangerous amounts of rain & flooding, too. Learn how to protect your family, home, or business from all the potential effects of hurricanes at www.Ready.gov/hurricanes.

Did you know: Most hurricane deaths and damages aren't because of winds – they happen because of flooding. Visit www.floodsmart.gov to find out if you live in a flood-prone area and how flood insurance can lessen the financial impact of a flood.

Remember, Turn around, Don’t drown; A mere six inches of fast-moving flood water can knock over an adult. It only takes two feet of rushing water to carry away most vehicles including pickups and SUV’s
July 17: The totals are in. Many locations saw 2+ inches of rain over the last few days, some saw 3-5 inches.

For many, the majority of this rain fell during a thunderstorm or heavy shower, in the span of only an hour to two hours:

July 16: At 11 AM, NWS Taunton reported a total of 0.57 inches of rain from Tuesday into Wednesday morning. Taunton Airport (KTAN), 8 miles SE of KBOX, has reported 1.96 inches. That's the type of differences we can see during the summer with localized heavier rainfall.

July 16: Two easy ways to get your yard or property ready for hurricane season:
1. Have a plan for bringing in all outdoor furniture & securing anything else that isn't tied down, should a storm threaten the area

2. Trim the trees and shrubs around your home. High winds can turn branches into projectiles during a storm
