Last week was awfully volatile -- going from snow to severe thunderstorm warnings in just 84 hours around Philadelphia -- as Mother Nature was throwing meteorological tantrums across the Mid Atlantic as the transition from winter chill to warmth begins its painstakingly slow transition. With all of the volatility over the past seven days, temperatures averaged out to exactly "normal" over the last week. As we all know, last week's weather was hardly that. Winds to 54 mph, squall lines, thunderstorms, and six inches of snow were just a few examples of the wild and wacky weather that greeted the Delaware Valley between Monday and Friday. The "normal" days in terms of not having wacky weather were Thursday and Saturday -- relatively modest weather was featured on both days.
Nationally, the tantrums were most severe across the High Plains of Montana and North Dakota -- with temperatures over twenty degrees below average for the week. This was in sharp contrast with high pressure over the Southeast bringing warmth to Deep South. Of course, severe weather and heavy rain greeted these areas on Thursday with a significant squall line sweeping through the Mid South.
