Probably a thunderstorm which may have Tornadoes.
A falling barometer typically indicates worsening weather conditions, such as storms or precipitation. However, it can also be an indicator of changing weather patterns that may not necessarily be bad. Observing other weather signs can provide a better indication of what to expect.
During a thunderstorm, you would likely experience a decrease in atmospheric pressure due to the active weather system in the area. This decrease in pressure can create a feeling of heaviness or discomfort in your ears or sinuses.
When the pressure is decreasing, what is likely happening is that air mass is getting less stable. So if the trend continues, expect the weather to become more unsettled. This could mean an increase ins surface winds, more clouds in the sky, or may precipitation may occur in the near future.
Low pressure areas form when an airmass warms, either from being over a warm land or ocean surface, or from being warmed by condensation of water vapour in large rain or snow systems. The warming causes the air layer to expand upward, becoming slightly thicker. This expansion then causes air in the upper troposphere to flow away, leaving less mass, and so less weight (pressure) at the surface. The lower pressure air at the surface then causes higher pressure air around it to flow toward lower pressure, but as it does, the rotation of the Earth turns the wind to the right, resulting in the counter-clockwise wind flow around low pressure (in the Northern Hemisphere...it flows in the opposite direction in the Southern Hemisphere). High pressure areas form when an airmass cools over a cool land or ocean surface. The cooling causes the air layer to shrink, becoming slightly thinner. This shrinkage then causes surrounding air in the upper troposphere to fill up the extra space. The added weight of the extra air causes higher pressure at the surface. The higher pressure air at the surface then tries to flow outward toward lower pressure, but as it does, the rotation of the Earth turns the wind to the right, resulting in the clockwise wind flow around the high pressure (in the Northern Hemisphere...it flows in the opposite direction in the Southern Hemisphere).
Typically, higher atmospheric pressure is associated with a dry day rather than a rainy day. This is because during a rainy day, low-pressure systems are more dominant as they bring in moist air and can lead to precipitation. In contrast, high-pressure systems are more likely to bring clear, dry weather.
You expect calm weather with few or no clouds.
When air pressure suddenly drops, you can expect unsettled weather conditions such as storms, strong winds, and precipitation. This drop in pressure often indicates the approach of a low-pressure system, which typically brings with it changing and potentially inclement weather.
High Pressure days, these types of pressure systems do not allow for cloud formation, therefore, you can expect sunnydays.
This would be a barometer. When the air pressure drops, you can expect rain or other bad weather like thunderstorms. On the other hand, when the air pressure rise, you can expect better weather. You can tell by using a barometer.
You would find bad weather.
Strong winds and precipitation.
Low pressure days are usually associated with stormy or cloudy weather.
When air pressure drops suddenly, it often indicates the approach of a storm or a weather system such as a low-pressure area. You can expect deteriorating weather conditions, including increased cloudiness, potential precipitation, and stronger winds. This drop in pressure is commonly associated with thunderstorms, rain, or even severe weather events like hurricanes or tornadoes, depending on the region and time of year.
Atmospheric pressure is measured by a barometer. There are several types. The one most likely to be found in a home is an anaeroid barometer.
High pressure systems are generally associated with fair weather conditions. This typically means clear skies, dry weather, and light winds. Cold temperatures can also be present in high pressure systems during the winter months.
A falling barometer typically indicates worsening weather conditions, such as storms or precipitation. However, it can also be an indicator of changing weather patterns that may not necessarily be bad. Observing other weather signs can provide a better indication of what to expect.
you should expect maybe cold weather in the Himalayas.
