Severe weather is returning to Massachusetts as the National Weather Service (NWS) has issued a Thunderstorm Watch covering much of the state until this evening. This alert warns residents of the potential for dangerous thunderstorms that may bring damaging winds, hail, frequent lightning, and localised flooding. The watch affects nine counties, including Berkshire, Essex, Franklin, Hampden, Hampshire, Middlesex, Norfolk, Suffolk, and Worcester. As reported by CBS News, meteorologists caution that storms could develop quickly and intensify as they move eastward, leading to possible power outages, property damage, and safety risks. Residents in the affected areas are urged to stay alert, monitor weather updates, and take necessary precautions to protect themselves and their property during this severe weather event.

What is a Thunderstorm Watch? Understanding the alert

A Thunderstorm Watch is issued by the National Weather Service when conditions in the atmosphere are favorable for the formation of severe thunderstorms. This watch does not mean that storms are currently happening but indicates that they could develop soon or are expected within the watch area. It serves as an early warning, urging residents to prepare and remain alert to changing weather conditions. Unlike a warning, which calls for immediate action, a watch is about preparedness and monitoring.

Thunderstorm Watch: Counties affected

CBS News reported the watch covers a broad area spanning nine counties in Massachusetts, including Berkshire, Essex, Franklin, Hampden, Hampshire, Middlesex, Norfolk, Suffolk, and Worcester. These regions are expected to experience the most significant weather activity. Because storms will be moving eastward, the timing and intensity of impacts may vary by location. Residents should stay updated, especially if they live in or near these counties, to anticipate the onset of severe weather.

What causes severe thunderstorms: Instability, wind shear, and moisture

Severe thunderstorms form when a combination of atmospheric factors come together:Warm, moist air near the Earth’s surface rises and encounters cooler, drier air aloft. This temperature and moisture difference creates atmospheric instability, allowing air parcels to rise rapidly and form towering thunderclouds capable of severe weather.Wind shear, the change in wind speed or direction with height, helps organize storms and contributes to their rotation. This rotation can enhance storm longevity and increase the chances of damaging winds or tornado formation.

High humidity provides the moisture necessary for cloud and rain formation, while lifting mechanisms like frontal boundaries push the moist air upwards, triggering thunderstorms. When these factors combine, storms can rapidly develop and intensify.

Thunderstorm threats: Strong winds, big hail, lots of lightning, and flooding

The National Weather Service highlights several hazards associated with today’s severe weather:Thunderstorms can produce strong wind gusts capable of uprooting trees, damaging roofs, and knocking down power lines, creating widespread outages and hazards from flying debris.

Hail of this size can cause damage to vehicles, roofs, windows, and crops, and poses a risk of injury to people and animals caught outside.Lightning strikes during thunderstorms are frequent and dangerous, capable of causing serious injury or starting fires, especially in dry areas.Heavy rainfall over a short period can overwhelm drainage systems, leading to flash flooding in streets, low-lying areas, and basements.While the tornado risk is low, there remains a possibility of isolated tornadoes forming, particularly in western and central Massachusetts. Tornadoes can cause catastrophic damage within minutes, so awareness and readiness are critical.

Severe thunderstorm timing and forecast for Massachusetts

Meteorologists predict storms will begin developing in the mid-afternoon hours, approximately starting around 3:00 PM, and then intensify as they track eastward across the state. The most active period for severe weather is expected between 3:00 PM and 8:00 PM, which is when residents should exercise heightened caution and be prepared for sudden changes in weather conditions.

How to stay safe during a thunderstorm watch

To stay safe during the thunderstorm watch, local emergency management agencies advise the following steps:

Understanding the increase in severe storms across

This thunderstorm watch fits into a larger trend of increasingly frequent and intense severe weather across the Northeastern United States. Scientists link this shift to changing climate patterns that:

What is a tornado and how does it form

A tornado is a violently rotating column of air extending from a thunderstorm to the ground. Tornadoes are capable of causing catastrophic damage due to their high wind speeds and sudden formation.Tornadoes usually form within severe thunderstorms when warm, moist air near the surface rises and interacts with cooler, dry air above. Wind shear causes the storm to rotate horizontally, which can then tilt vertically to form a funnel cloud. If this funnel touches the ground, a tornado occurs.Given the rapidly evolving nature of thunderstorms, it’s critical to stay informed throughout the day. Follow updates from trusted sources and be prepared to take immediate action if warnings escalate from watches to warnings.Also Read | Dwayne ‘The Rock’ Johnson’s real estate empire: Inside his lavish mansions, villas, and luxury estates
