Blocky Pattern Continues Spring Arrives With Another Storm System

At least parts of South Central Pennsylvania got a cheap thrill today as the 3rd noreaster in 10 days ravaged Long Island & continues to pound Southeastern New England with 1 to 2 feet of snow. Now we turn our attention to the next 7 days and the pattern we are in is not done yet.

It appears that this stormy pattern with blocking or at least a blocky signature continues into next week as Spring arrives. Sadly however the new season didn't receive the e-mail that the upper atmosphere is not ready to accept this idea. We really don't see a lot of change in the dynamic pattern we have been. Yes the super strong blocking high has weakened but there is still enough of it there to continue the southern displacement of the jet stream. In addition it appears that some genuinely cold air for this time of year is coming next week as well.

First things first is we need to resolve the complex upper air set up in the Eastern US that resulted in today's snow. The large Great Lakes upper low swings around and moves through Wednesday with cold unstable air so look for snow showers and snow squalls that could whiten the ground up in some spots and perhaps a bit more than others. Once this pushes to the east, it will be cold and mostly dry into the weekend. Saint Patrick's Day looks good with sunshine and highs in the 40s. It should be also nice on Sunday as we attempt the low 50s before another cold front moves on through.
