Marching in like a LION!!

Well this is the first 3 hours of march and it marching in like a lion who has eaten in a few day and is anger. This storm system is anticipated to have a major Severe weather outbreak tomorrow. The Storms Predication center doesn't issue this type of map without a very strong feeling that something big will happen over the next 24 hours.

A very high potential for severe weather exist within the Purple circle, a moderate in the red and slight chance in the green. Now don't be fooled with this map pretty much anywhere inside of the brown area could easily see some severe weather. I think around here we stand a good chance for a strong thunderstorm tonight.

If we get a Strong thunderstorm tonight we could be looking at more rainfall which is not good for the streams and rivers. The major concern is flooding and because of the amount of ice on the rivers we could see ice jam flooding where the ice breaks apart but literally jams(dams) up in a location and then after building enough water behind the jam it breaks allowing the water to rush downstream. The last noticeable case of this that occurred in the Pittsburgh area in 1996 when after the ice on the Oil City creek decided to jam and held for a significant period of time, holding back massive amounts of water. Then almost around the 6 pm news it let loose. Which meant flooding downriver in a few hours. This could happen again the different between that snow melt/rain event is that that one had temps that reached into the 60's and very dense fog developed over the Laurels which is a snow killer (eats snow rapidly), today we are only predicted to reach into the mid 50's.

As the weather develops I will update.
