We are tracking a very significant warm-up starting Sunday, and lasting throughout Thursday of next week. Our forecast team has just got done crunching the models, and sending over our high-definition model for everyone to review (top of screen). As you can see, we are going to be in a short cold-spell, but, this will all be changing once the weekend time rolls around! As of here, we can track a significant warm-up, and even see down near Philadelphia, that temperatures could reach over 95-degrees! Our map is mostly self-explanatory. And no… we didn’t try to make it look like a “blue-tornado”.

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.

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

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
