The first 1/2 of March pretty much went as expected for the most part.
The second 1/2 of March, which we have already moved into, will feature a very rollercoaster March-like weather pattern across the CONUS. As mentioned in the previous post at the start of March, the pattern was already expected to be once again transitioning by now, which it has done so. The period of significant -EPO/-AO/-NAO has quickly relaxed, giving way to an EPO/AO/NAO that is in flux, and will continue to be through the end of the month. What this means is we will see periods of AO/NAO ridging, pretty much transient or meandering nature, but nonetheless still there. With an EPO bouncing around the +/- sides of neutral and a significant/lengthy -PNA period expected, this will support constant troughs dropping in from the Alaska vicinity, down into the West Coast, and then moving across the CONUS below the transient AO/NAO ridging.
This will all lead to an active, but steadily moving weather pattern across the CONUS. Best snow chances will be across the northern half of the sub-forum, namely the heavy hit corridor of the winter (MN/WI/MI), with severe weather opportunities possible across the southern half of the sub-forum. This will also be a pattern with temperatures that bounce around quite rollercoaster like as well, with mild temps ahead of storm systems and cool temps behind them. Once again, all in all what I would consider to be a typical March-like pattern.
Looking ahead towards getting into the beginning of April, it looks quite likely a similar pattern will continue.
