 Image Courtesy: Monica in Nanty Glo (July 17, 2010) Most of us know that lightning travels faster than thunder (because light travels faster than sound). Well, today’s weather trivia question asks: How much faster is lightning than thunder? a) 5 times b) 40,106 times c) 882,353 times Find out the answer after the jump… (Read More)  Lightning Strikes Sign - May 28 I was back in Pittsburgh on Wednesday and they were hit hard with weather. There were places with golf ball sized hail and even a tornado confirmed just to the west in Jefferson County, Ohio. While I was there, I managed to record some video of the heavy rain and lightning. There was also a lot of ponding (or laking) on the roads. You’ll see in the video below how much water was on the road. That comes towards the end of the video. We normally say “turn around, don’t drown” but there really isn’t anything you can do when you don’t see the water coming. That was the case yesterday on Route 22 between Imperial and Robinson, PA (near the Pittsburgh International Airport). With it raining so hard, I didn’t see the water on the road until the last minute. I got about 3/4 of the way through the miniature lake and my car started to slow down. I got a little nervous, but made it through… luckily. You can see the truck in front of me go through it in the video below. There’s more after the jump. Click below. First off, this weekend will not be a complete washout. Secondly, temperatures are going to cool off compared to today, but they will actually be close to average. Ok, here’s the details. An upper level low will move eastward tonight through Sunday, spreading a few thundershowers into the area. The best chance for rain [...] Warmer-than normal temperatures, a bit of humidity and a cold front arriving late in the afternoon or evening usually spells rough weather.

Now, they have bumped up the hail criteria to 1″ (or quarter-sized).  Severe Hail Criteria Changed It’s been quite a week as far as rain goes, and we didn’t even have that many thunderstorms! Typically we get most of our rain in July and August from cold fronts and thunderstorms, but not this year. We had our second steady rain-event for the week on Friday, and here’s what we ended [...] The humidity is coming, and it’s long overdue.

 Keep those weather picture coming! Send them to [...] Thunderstorms with heavy rain and frequent lightning will cross the area tonight as a cold front moves through. This front will move south of the state on Friday, bringing in some slightly cooler air. There will be enough moisture left over to generate a pop-up thundershower tomorrow, but most spots will stay dry. Whatever [...] Check out these nice shots sent in from our weather spotter in the Moxham section of Johnstown.

This system is headed our way for tomorrow! Below are some cool pictures of mammatus clouds (thanks Chuck Mahon) from the severe thunderstorms that rolled through the region on Monday. Mammatus clouds are extremely rare in our area as they are found on the underside of the anvil of a severe thunderstorm.

I helped Tim “build” a new five day forecast [...] I came into work around 3:00 PM today and looked at Early Warning Doppler 6. It shows a decent line of storms moving into the viewing area. I tracked them through the afternoon. As of 8:50 PM, when I’m writing this, there are still a few storms in the eastern portion of the viewing [...] Check out these cool pics sent in from our blog storm chaser Ron Shawley: Here’s a look at severe weather reports from across west central PA dating back to 1950.
