Heat waves, cooler, and rainy weather CAN all be caused by one of the events known as El Nino and La Nina. If you remember the heat wave last year where temperatures reached 100+ in some areas, El Nino was to blame. Here is why: El Niño and La Niña events are a natural part of the global climate system. They occur when the Pacific Ocean and the atmosphere above it change from their neutral (‘normal’) state for several seasons. El Niño events are associated with a warming of the central and eastern tropical Pacific, while La Niña events are the reverse, with a sustained cooling of these same areas.  The atmosphere

An unexpected cold front will sweep the region, leaving the cold-wet white stuff falling out of the sky again. Don’t worry! It will not be much, so keep the snow shovels in, but bring out the hats and coats, it’s going to be a cold one! Area A: A small dusting will coat cold surfaces and will make the roads wet, causing a concern for icing to occur so travel safely Monday Morning. Snow will fall throughout Tuesday off and on. Area B: Cold temperatures will let snow fall off and on between Sunday and Tuesday.

May 1, 2017 was an active severe storm day in western and central Pennsylvania. After a couple days of summer like temperatures, a strong cold front moved through bringing cooler temperatures. The Storm Prediction Center had most of Pennsylvania under “enhanced risk” for severe weather. At the time of writing, it feels more like a fall day than a spring day. I was documenting the storm that moved through at the Jacksville Esker at West Liberty and Mt. Union Roads in Worth Twp, Butler County, PA. I chose that vantage point because I am able to get a great view of the storm and I have a couple escape routes. I

As I sit here and think about what to type, I have one word. Amazing. This was the first actual chase I had where I had a co-pilot. Even better, he knew about weather and what to look for! Not many chasers are lucky to have a co-pilot/navigator during chasing. Dean and Laura were alone yesterday, which was a bit worrisome since we were under an Enhanced Risk and tornado watch. I picked up my navigator just north of Butler, and we started heading south to Saxonburg, PA. They have a history of tornadoes and funnels since it’s so flat. When we pulled in, it was probably only 6-minutes we were

As with anything that can come with severe weather, damaging winds can cause a ton of damage. What exactly are the types of damaging winds? They are explained below. Damaging winds are often called “straight-line” winds to differentiate the damage they cause from tornado damage. Strong thunderstorm winds can come from a number of different processes. Most thunderstorm winds that cause damage at the ground are a result of outflow generated by a thunderstorm downdraft. Damaging winds are classified as those exceeding 50-60 mph. Wind speeds can reach up to 100 mph and can produce a damage path extending for hundreds of miles. Since most thunderstorms produce some straight-line winds, those who

The NWS has already placed Western, PA in a Tornado Watch. An organized line of storms with embedded mesovortices and bowing segments from Lake Erie through extreme eastern OH is moving east at around 40 kt into the Pittsburgh area. A tornado watch is likely to be issued for Central, Pa within the hour. Severe storm threat with damaging wind and a few tornadoes should continue to expand eastward into western NY and central PA this afternoon. A tornado watch will likely be issued soon.

This is an updated outlook that has just been issued by the SPC (Storm Prediction Center) for today (May 1, 2017). Thunderstorms are expected to develop and overspread much of the lower Great Lakes region, the upper Ohio Valley and central Appalachians into the Mid Atlantic region today, accompanied by potentially damaging wind gusts and the risk for a few tornadoes. This activity seems likely to eventually consolidate and grow upscale into an organizing squall line as it crosses the Allegheny mountains and plateau, and to the lee of the Blue Ridge, by early evening. There is an increasing potential for damaging surface gusts, given the strength of the ambient wind fields,

You hear thunder in the distance, maybe even feel a breeze and smell rain. You look out your window, and you see dark storm clouds in the distance. The news station alerts you of the possibility of storms in your area that afternoon. Severe storms can bring a multitude of sporadic conditions with it, microbursts are one of them. It all starts with a thunderstorm, but what exactly is a microburst? Microbursts AKA downbursts, are made of wind rushing down to the ground. Once the wind hits the ground, it spreads in all directions. Wind speeds in a microburst can be 60-100 mph, damaging roofs, snapping trees and knocking over power poles.

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
