The coming pattern change back to cold has been long advertised and fits the overall theme of El Nino winters. The question now centers squarely on not “if” the cold is going to return, but just “how” cold will it get? Should we spend time in Phase 8 then the door opens for another opportunity to rival the magnitude of cold we saw in January. The strongly negative AO and NAO argues for pronounced high latitude blocking to develop yet again, and likely with more staying power than our January blocking episode.

But enough about the return of below normal temperatures. What is the longer range guidance suggesting as far as the overall precipitation pattern goes? During the pattern “transition state” (late week into Week 2), we favor a more active precipitation pattern as at least (2) more organized storm systems should roll through the Ohio Valley. Specifically, we’re targeting a system 2/8 into 2/9 followed by a more organized and heavier precipitation maker in the 2/11 -2/13 timeframe.

Beyond mid-month, the majority of extended, long range forecast models highlight a drier than normal pattern returning to the picture. This is forecast to continue into the 1st half of March. A more active (wet) pattern is forecast for the Southeast. Not shocking, especially given the anticipated colder than normal regime.

This doesn’t mean snowfall will run below average, but it’s also impossible to get specific with winter storm potential more than a week out. While we’ll keep an eye on next weekend, the threat of winter weather potential will increase through the 2nd half of the month and into the 1st half of March with the colder pattern returning. The latest ensemble guidance is bullish on a snow pattern emerging during that time period.

Perhaps we’re gearing up for a busy 2nd half of the season?
