Pattern change?

TWC today was showing how the NAO (North Atlantic Oscillation) is shifting from a negative phase(cold, snowy South-NE) to a slightly positive phase(milder-wet/rainy South-NE). This would mean our cold air outbreaks will not have the severity as the last one for the next 7-10 days. the key question is...is this a temporary shift? Or will we return to the negative(colder) phase as we head into February? My guess is this is a temporary shift (like the annual January thaw) that will revert back to the deep low over eastern Canada that will bring back the frigid air to much of the lower 48 in another 10-14 days. We still have plenty of time for more freezes plus the opportunity for another southern snow/ice storm. Stay tuned.

In the short term, this week will start mild with some showers around Monday into Tuesday. A weak front clears us on Wednesday with a brief warm up Thursday ahead of our next front on Friday. That front looks stronger with the possibility of some strong storms on Friday.

Kind of a bummer watching the playoffs without our Saints.
