We’re heading into April shortly and while the calendar says spring, winter continues to prevail through the first week. The spring snow doesn’t seem to be over, and with the weakening El Niño, late seasons snow remain in play.
For Days 7-14, we’re going to moderate a little bit out of the cooler pattern we’ve been in with the snow events. Every pattern has to recharge, and I don’t believe this is the seasonal shift. What do those memes call it, “fake spring #2”? Something like that…is what we can expected for the second week of the month.
The western trough builds, the NAO/AO go positive and the PNA goes negative. These are all signs to a relatively nice stretch of spring weather taking place.
However around April 11/12, we begin shifting the other way, with the NAO/AO going negative and the PNA running into positive territory by the end of week 3 of April.
For Days 14-21 it doesn’t look overly exciting, but you see the GFS picking up on an eastern trough with a negative anomaly in the Canadian Maritimes, and the Euro has it just farther to the north. This certainly sets us up for an interesting pattern for Patriot’s Day week/April break, which currently looks like it may linger into the first half of May.
