With storm season already in progress, now is the time to become aware of tornado safety and preparation. While Pennsylvania doesn’t get as many tornadoes as tornado alley does, we still have tornadoes spin up every now and again. Here is what you need to know about safety and preparation. To start, what exactly is a tornado? A tornado is a narrow, violently rotating column of air that extends from the base of a thunderstorm to the ground. Because wind is invisible, it is hard to see a tornado unless it forms a condensation funnel made up of water droplets, dust and debris. Tornadoes are the most violent of all atmospheric

Pennsylvania won’t see much in the way of any severe storms (most areas may see a low severe system). Thunder and rain MAY occur in some areas, but I wouldn’t expect anything severe. The outflow boundary has stalled across parts of eastern Oklahoma and northwestern Arkansas through southern Missouri, but continues to advance eastward into the lower Ohio Valley, where mostly low severe weather probabilities are being maintained. Lingering severe weather potential is probably maximized near the intersection of the outflow and a stalled frontal zone (roughly along the I-70 corridor of Indiana), but seems likely to diminish by late evening in the presence of weak/weakening instability.

Severe thunderstorms are expected from parts of south central Texas northeastward to portions of the Ohio Valley/northern Middle Atlantic region Saturday into Saturday night. These storms will be capable of large hail, damaging winds, and a few tornadoes. THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS FROM SOUTH TEXAS TO THE NORTHERN MIDDLE ATLANTIC… (Valid April 29-30) This system is forecast to shift into the southern High Plains region by the end of the day 1 period as strongest mid-level flow finally rotates through the base of the trough into northwest TX/western OK. Given this scenario, strongest mid-level height falls will not spread into west TX until late afternoon. As a result, large-scale

In the Ohio Valley and across Pennsylvania, there is a chance for some rumbles of thunder and rain this evening into early morning on April 29,2017. An updated article will be written if anything changes. Keep up to date with the radar and forecasts in the meantime. However, most of the severe weather remains in the southern and western areas as talked about below. (Current radar loop) A relatively subtle mid-level impulse over the Ozarks this morning will largely parallel the OH River as it continues east-northeastward through the afternoon and evening hours. This impulse will be on the northern periphery of considerably rising upper heights and gradually warming mid-level temperatures.

A suspicious cloud formation develops during a thunderstorm, prompting concerns of an impending twister. But not all funnel-shaped clouds are tornadoes. A keen eye and patience is needed to spot the genuine from the fake. Here in this article, we will explain the difference between a real tornado, and clouds that are often mistaken for a tornado. While many clouds may begin as funnel clouds, they are not the same as a tornado. A tornado is a violently rotating column of air in contact with the ground and extending between a convective cloud (like a wall cloud) and the surface of the earth. Rotation is the key property when observing suspicious, tornado

In wake of the severe weather season, I felt that touching base on thunderstorm and lightning safety would be an important topic to discuss. Most of us know the infamous saying “When thunder roars, go indoors”, but what about the reason behind it? Let’s take a look below. All thunderstorms are dangerous, and all thunderstorms produce lightning to some degree. Over the past thirty years, lightning fatalities have decreased, but lightning continues to be one of the top three storm-related killers in the United States. On average, fifty one people are struck by lightning in the United States alone. So what else comes with a thunderstorm warned system? If you said

With the severe weather season underway, now is a good time to go over the difference between tornado,  severe thunderstorm watches and warnings, advisories and outlook. What does each one mean? Your questions are answered below. What is a Watch? A WATCH means that the potential exists for the development of severe thunderstorms or tornadoes, depending upon the specific type of watch issued. In the case of a tornado watch, this DOES NOT mean that a tornado has been seen or even indicated on radar…it just means that conditions are favorable for the formation of tornadoes in thunderstorms. Similarly, a severe thunderstorm watch means that conditions are just favorable for the development

The Northeast will enjoy a taste of summer late this week into the weekend and some cities, including Washington D.C., could record their first 90-degree day of the year. The jet stream will bulge northward into eastern Canada to allow a warm, southerly wind flow to develop across the East, which will send temperatures to the warmest readings of the year so far in parts of the region. The warmth will begin to build in the Northeast and mid-Atlantic Wednesday, but by Thursday it will feel summery as highs reach the 80s from western and central New York into Pennsylvania, eastern Ohio, West Virginia, Maryland, Virginia and North Carolina. These temperatures are 15

Jet streams are like rivers of wind high above in the atmosphere. These slim strips of strong winds have a huge influence on climate, as they can push air masses around and affect weather patterns. The jet streams on Earth — other planets have jet streams as well, notably Jupiter and Saturn — typically run from west to east, and their width is relatively narrow compared to their length. Jet streams are typically active at 20,000 feet (6,100 meters) to 50,000 feet (9,144 meters), or about 7 miles (11 kilometers) above the surface and travel in what is known as the troposphere of Earth’s multi-layered atmosphere. While they are fairly narrow,
