Convective Outlooks SPC issues Day 1, Day 2, and Day 3 Convective Outlooks that depict non-severe thunderstorm areas and severe thunderstorm threats across the contiguous United States, along with a text narrative. The categorical forecast specifies the level of the overall severe weather threat via numbers (e.g., 5), descriptive labeling (e.g., HIGH), and colors (e.g., magenta). The probabilistic forecast directly expresses the best estimate of a severe weather event occurring within 25 miles of a point. The text narrative begins with a listing of severe thunderstorm risk areas by state and/or geographic region. This is followed by a concise, plain-language summary of the type(s) of threat along with timing that is

The National Weather Service: Storm Prediction Center in Norman, OK has issued their Day 2 convective weather outlook. Mid Western PA and most of Central PA will be in a SLIGHT risk for severe weather. Even though the words slight do not seem like much, SLIGHT can bring hail over 1-inch in size, winds above 65 MPH, and tornado spin up between EF0-EF2 (Possibly EF3 if conditions are right). Always be weather alert during times like this. May has brought havoc to the Pennsylvania region, for example, May 31st, 1985 was the worst tornado outbreak this state has seen. Dr. Greg Forbes with The Weather Channel, has issued TORCON indexes of

Yesterday, I went ona chase like no others during the daylight. We had a storm moving in from Ohio, and I had the perfect vantage point. I was going to be busting through the middle of a 1″ hailcore. This was also my first time chasing in unknown area. As you can see, the storm was growing intensity. Here are a few pictures of the system itself. Unfortunately, the storm decided to head more north than East, so I was back on the move. Weaving in and out of the hills of Ellwood City, I was able to get on top of the mountains and follow it north for a few

Tonight and through tomorrow, we can expect to see a significant and possibly dangerous storm system move through the area. We will break it down area by area, and day by day. Red: Wednesday Night will bring a potentially dangerous storm system. This includes gusty winds upto 70-MPH, and isolated tornadoes with spin-ups very possible due to the atmospheric conditions being just right for convection. Downdrafts in upwards of 70 MPH winds can be very likely. Tomorrow, some gusty winds and mostly rain-storms will move through, causing a hazard of flooding, especially in low-laying areas.   Yellow: Tonight you can expect gusty winds and some stray showers to occur.

Today, the commonwealth will see seemingly warm temperatures across the majority of the state. In some places, the temperatures could reach nearly 60-degrees! In addition to the amazing sun, we will see some gust winds, upto 15+ MPH. But no worries, we have ZERO advisories put into place and we are not in a SPC outlook as of now.\ If you see above, we are tracking two storms, both very different. The top one (larger) in Sioux City, is a snow and ice maker. It’s moving it’s way near the great lakes. Whereas the storm near Springfield, is a tornado-proned storm that will be damaging areas such as Tennessee, Kentucky, Alabama,

August 21, 2017 Eclipse Day! No human action can disrupt the incessant dance of the cosmos, and the Moon’s shadow will not wait on you if you’re not ready. Like a mindless juggernaut, it plows its way through space toward a collision course with Earth. As predicted by the astronomers decades in advance, the shadow arrives with perfect accuracy, and touches down in the north Pacific Ocean at 16:48:33 UT*, at local sunrise. (At that spot, the Sun will actually rise while totally eclipsed. This is a sight few people – even veteran eclipse chasers – have seen, and from what we hear, it is quite uncanny.)

Welcome to March 20th, where the first day of spring has sprung! As the story goes, April showers bring May flowers. This will be the case, as we are tracking a large rain-system about to move in! As we take a look at the water-vapor, we can see a large rain-wrapped severe storm in the center (below) Included is what the national radar looks like as well. We do notice the Storm Prediction Center does have south-western Pennsylvania in a Day 1 Outlook for Thunderstorms. The temperatures are warmer than usual today.
