Blocky Pattern Continues Spring Arrives With Another Storm

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.

Blocky Pattern Continues Spring Arrives With Another Storm System

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.

SPRING ARRIVES MARCH 20TH 12:15PM

The next shot of cold air next week actually will be fairly cold coming from Northern Canada. On the first day of spring as the map above shows you can look forward to temperatures 10-15 degrees below average. Don’t be surprised if we wind up with a couple of days next week with daytime highs not out of the 30s!. Now comes the set-up for the next storm.

All the puzzle pieces are in place (again). We have a blocky looking pattern in Northeastern Canada out to Greenland, a low at 50N 50W and the next round of energy diving into the Tennessee Valley. Once again the question will be one of how much room.

That is what the surface looks like on the European for next Wednesday morning. The storm is offshore and to the south. The keys to this will be strength of the trough and whether the low to the northeast gets out of the way just enough to allow for some room and some lifting. We have a lot to watch here. The pattern isn’t done yet.
