Teleconnections Still Aren’t Playing Nice; Does This Change In April?
Seemingly all winter, we’ve been unable to get the NAO, AO, EPO, PNA, and MJO to cooperate and align. The end result is an overall pattern that has been unable to produce widespread, sustained cold. As we progress through the remainder of the month, the contradicting signals will continue.
Despite the negative NAO (a signal notorious for drawn out cold patterns this time of year), the deeply negative PNA and developing strongly positive EPO will hold off any significant cold. Even in the immediate term, notice how the signals are’t matching up (i.e. strongly positive NAO with a negative EPO).
The MJO is forecast to rumble into Phase 4 to close the month and this is also a phase that favors eastern ridging.
Given the above, to no surprise, the consensus of model data is for a warm, wet close to the month.
Does this pattern change in April and we actually see some alignment with our teleconnections? What about the MJO? Does the current movement continue and do we get into the colder Phase 1 as currently shown? Interesting times ahead as we sort through the data. Our official April Outlook will be online late week.

Wednesday Morning Rambles: Midweek Storms, MJO Impacts On Late March Pattern…
I. The morning is off to a quiet, chilly start, but clouds will lower and thicken through the morning and rain will soon follow. Periods of moderate to heavy rain can be expected this afternoon into the early evening hours, including widespread 0.50″ to 1″ with a few locally heavier amounts.
II. A changeable weather day is on tap Thursday with a couple of rounds of storms expected- late morning and again during the evening and night. The initial round of storms will lift northeast across the state Thursday morning into early afternoon, courtesy of a warm front. Highs will flirt with 70° tomorrow afternoon once the storms move out.
A cold front will then sweep through the region during the overnight. Additional storms (some potentially strong to severe) will take place as the front moves through the region.
III. We’ll turn MUCH colder, but at least the sunshine will return as we move through the weekend. Lows in the 20s can be expected.
IV. Our next storm system looks to arrive Tuesday. From this distance, it appears this will be a potent system, including strong winds and heavy rain.
V. Longer term, we continue to watch the various players align. The MJO looks to amplify and rumble into Phase 3 by late March. The movement through Phases 1-2 can at least generate transient cold for our neck of the woods before Phase 3 favors the brunt of the cold across the West. Interestingly, this is what the latest European ensemble is also showing.
