[05.17.2025 AM] NWS Boston/Norton EM Briefing: Scattered Severe Thunderstorms This Afternoon
by BOX Operations - NOAA Service Account 17 May '25

17 May '25

Good morning, Following is an update regarding the potential for severe thunderstorms in portions of Southern New England this afternoon. We do want to mention that an initial round of widely scattered thunderstorms could develop during the morning hours, approximately 9 AM to noontime. These storms, if they develop, are not expected to rise to the level of producing severe weather, although lightning and passing heavy downpours are still possible. The greatest potential for severe thunderstorms today is this afternoon to early evening, between 2-8 PM, and largely confined to central and western Massachusetts and portions of northern Connecticut. All severe weather hazards are possible in severe thunderstorms today, including damaging straight line winds, large hail, and a low chance for a tornado. Because of the cloud cover around, the risk for severe weather this afternoon in eastern Massachusetts and Rhode Island is low, but we'll be closely monitoring for any changes. Expect this to be the last weather briefing, unless there are significant changes which would warrant otherwise. Thank You! Meteorologist: Andrew Loconto If you have any questions or would like more information, please don't hesitate to contact us.

[05.16.2025 PM] NWS Boston/Norton: Thunderstorms This evening and Saturday
by BOX Operations - NOAA Service Account 16 May '25

16 May '25

Good afternoon, Here is the latest briefing for potential severe weather over the next day and a half. There remains a chance for an isolated thunderstorm or two this evening across far western Massachusetts but the main concern for severe weather is Saturday. Confidence in the area that is most likely to see severe weather on Saturday has increased since the last update. While most of southern New England will have a chance to see severe storms, the highest risk will be across western areas of Massachusetts and Connecticut. There may be an initial round of storms Saturday morning, but these are expected to remain below severe limits. The main risk for scattered severe storms arrives later in the day with the potential for thunderstorm activity anytime between 2 and 10pm. Confidence in the severe weather potential and timing for Saturday is rated as moderate - as cloud cover and possible showers/embedded thundershowers early in the morning could affect the afternoon severe weather risk. Thank You! Meteorologists: Hayden Frank, Caitlyn Mensch, and Francis Tarasiewicz If you have any questions or would like more information, please don't hesitate to contact us.

[05.16.2025 AM] NWS Boston/Norton: Thunderstorms Today and Saturday
by BOX Operations - NOAA Service Account 16 May '25

16 May '25

Good morning, Following is an update to the weather briefing sent yesterday outlining the potential for strong thunderstorms today and Saturday. For today, the main risk area for thunderstorms lies across western Massachusetts and Connecticut mainly after 3 PM til sunset. It is possible that one or two could approach severe limits, but the majority of storms would not likely reach these levels. Confidence in the thunderstorm location and timing for today is rated as moderate to high, but is low on the chance of a storm or two becoming severe. Saturday is still the day we are most concerned for regarding the potential for severe weather, and while there is a threat for severe storms in most of Southern New England, the threat is slightly greater in western Massachusetts and Connecticut between noon and 9 PM. Confidence in the severe weather potential and timing for Saturday is rated as moderate - as cloud cover and possible showers/embedded thundershowers early in the morning could affect the afternoon severe weather risk. Thank You! Meteorologist: Andrew Loconto If you have any questions or would like more information, please don't hesitate to contact us.

[2025.05.09 AM] NWS Boston EM Briefing: Heavy Rainfall Friday into Saturday
by BOX Operations - NOAA Service Account 09 May '25

09 May '25

Good morning. The Flood Watch remains in effect from 5am Today through 8am Saturday and was expanded east into Worcester and Windham Counties. No major changes to the forecast since last night with 1.5 to 3.0 inches of rain expected today. Rain is expected to bring a renewed threat for river flooding along much of the CT river, with several points expected to reach minor flood, with moderate flood levels possible. Moderate to heavy rain will likely align with the evening commute and may cause travel issues with minor street flooding possible.

[2025.05.08 AM] NWS Boston EM Briefing: Heavy Rainfall Fri AM through Sat AM
by BOX Operations - NOAA Service Account 08 May '25

08 May '25

Good morning, A Flood Watch has been issued from 5am Friday to 8am Saturday for the CT river valley into the Berkshires. We are expecting another round of heavy rainfall across the region Friday morning through Saturday morning. Given the antecedent wet conditions and high stream flows from earlier this week, there is a renewed threat for river flooding especially in the CT river valley. While we are not expecting flash flooding to occur, minior street and nuisance flooding is possible which could affect both the Friday morning and afternoon commutes.

[2025.05.03] NWS Boston EM Briefing: Severe Weather Later Today NW of I-95
by BOX Operations - NOAA Service Account 03 May '25

03 May '25

Good morning everyone... Attached is a brief one-pager on the potential for scattered severe thunderstorms northwest of I-95 between 2 and 10 pm this evening. The greatest risk appears to be across western/central MA perhaps reaching southward into portions of northern CT. The main severe weather threat will be for locally damaging straight line wind gusts with secondary concerns for hail along with heavy rain/urban street flooding. We have gone ahead and attached the one-pager along with the Severe Weather Outlook today. Also, we have attached some new experimental severe weather timing graphics for Amherst & Worcester MA as well as Hartford CT. These graphics highlight the probability with respect to time of severe weather occurring within 25 miles of that particular location. It is broken down by the severe weather type...which in this case is mainly damaging wind gusts followed by hail. We would love to hear your feedback on these products and if it is something you would like to see in the future. Thank You!
