We are continuing monitoring thunderstorms that will be moving in to the area. The main question will be the timing. The Storm Prediction Center has backed off a bit on the areal coverage of severe probabilities, with areas northwest of Pittsburgh, having the chance of seeing storms with damaging winds and large hail. Timing would be during the late afternoon and evening, with the risk expected to end by midnight with the loss of daytime heating. We will continue to update the forecast as it changes. *images are property of the NWS*

Some of us have seen the scene from the move “Twister” where the crew is driving through a field. Unfortunately, that same scene plays out in “tornado alley,” an area of the United States known for severe thunderstorms and tornadoes. Driving through one’s field is considered trespassing. Farmers probably don’t appreciate a bunch of storm chasers ruining their crops. Crops are a farmer’s livelihood. When I chase and document storms, I stay on public lands. Examples are state game lands and/or state parks. I sometimes pull off the side of the road if space permits to view a storm. I try to put myself in the property owners shoes. If I

Annually, 37,000 people die each year in vehicle crashes. An additional 2,350,000 are injured or disabled in vehicle accidents yearly, just in the United States. In March of 2017, the storm chasing community lost 3 storm chasers, 2 of which were independent contractors for The Weather Channel. Kelley Williamson and Randy Yarnell were media chasers. Unfortunately, careless driving was the fate of the two and Corbin Lee Jaeger was the victim to their careless driving. But, this post is not to downgrade any of them, but to bring light to careless media chasers. First, media chasing is different than regular storm chasing.

Severe weather is likely in areas that are in the yellow and dark green. Strong heating will result in weak to moderate instability by afternoon and isolated to scattered strong to severe storms will be possible. A slight risk has been placed for the Northern corner of the state which could bring damaging wind, hail, and severe thunderstorms. A marginal risk has been placed for much of the center of the state, including the Pittsburgh area and areas north of the city, and a thunderstorm risk (mostly isolated, non-severe storms) has been placed for much of the eastern half of the state. Thunderstorms may be isolated and or may pop up

A major warm-front will be sweeping Pennsylvania, and yes, temperatures will be reaching near 90-degrees on Wednesday! Even though today, Monday, will be less than 70-degrees – do not fear! The warm air will be coming in tomorrow which will cause the atmosphere to gradually warm for the summer time. But please note, non-severe thunderstorms are expected to “fire” over Ohio, bringing us warmth but also rain. High winds are also expected, but the forecast is really unclear if we will see severe-criteria thunderstorm cells or not. Pittsburgh, PA Forecast State College, PA Forecast Philadelphia, PA Forecast The NWS SPC Outlook for Day 2 highlights thunderstorms for Erie County, and surrounding

Thunderstorms are expected across much of the Upper Midwest on Wednesday. However, uncertainty is too high at this time to pinpoint where, or how much, strong to severe thunderstorm activity may develop. Storms should remain non-severe for most of Pennsylvania as of right now. The outlook could change from now until Wednesday and will be updated IF changes do arise. Be sure to keep an eye open for any updated forecasts that may be written. Outlook map for Wednesday, May 17, 2017. Subject to change. *Map is property of NOAA, NWS and SPC*

A major pattern change is ahead after Mother’s Day, which will bring several big changes in the nation’s weather in the new week ahead. An omega block has influenced weather conditions across the U.S. so far this month, but this clog in the atmosphere is finally expected to break down next week. The pattern will slowly transition to an upper-level trough, or southward dip in the jet stream, in the West and an upper-level ridge, or northward bulge of the jet stream, over the East. The jet stream pattern is expected to change after Mother’s Day, with a trough developing in the West and a ridge over the East. The result

Much of the rain will affect parts of the western part of the state tonight (mostly the southern parts of the state), whereas, rainfall will affect much of the eastern half of the state tomorrow into Sunday. Temps will remain on the cooler side much of the weekend, but will warm up towards Sunday (for some areas) and Monday. Any additional updates will be made as they come in. Rain will taper off completely by Monday as the temperatures increase. Don’t get used to the dry weather, rain will return by Wednesday. *Maps are property of Weather Underground*

In order to protect people and systems that might be at risk from space weather effects, we need to understand the causes of space weather. The sun is the main source of space weather. Sudden bursts of plasma and magnetic field structures from the sun’s atmosphere called coronal mass ejections (CME) together with sudden bursts of radiation, or solar flares, all cause space weather effects here on Earth. Space weather can produce electromagnetic fields that induce extreme currents in wires, disrupting power lines, and even causing wide-spread blackouts. Severe space weather also produces solar energetic particles, which can damage satellites used for commercial communications, global positioning, intelligence gathering, and weather forecasting.

Storm chasing has changed a lot in the past decade. Advances in mobile internet has opened storm chasing up to anybody who has a smart phone. Years ago, a storm chaser had to find a library or any place with internet to check data on impending storms. Storm chasers had to know how to read the sky, meaning knowledge of cloud and storms types were a must. There are increasing numbers of new storm chasers each year. People chase for various reasons. Some like to photograph storms. Some like to experience the weather. Some sell their footage and./or pictures for profit. And last but least, there are those doing research on
