As mentioned in the February thread, the pattern we are now is fairly zzz overall. Ridging around the West Coast and PV location between Greenland and the Hudson during this stretch. Mostly a duster clipper pattern for most, though maybe a bit more at times (See late week clipper), though more MN/WI/MI favored then. A to BA temperature wise for most as well.
Around or just after Valentines Day is the time to watch for our next significant pattern shift. It's looking increasingly likely that we will shift into a +AO/+NAO/-PNA pattern, with still some question on the EPO (+ or neutral seems most likely). Also it looks like the PV will still be persistent just north of the Hudson up in Canada. That pattern would be favorable for a shift back to an active pattern, with quality storm potential (Rain & snow).
Not surprisingly some differences on how the EPS and GEFS are handling the pattern. The EPS are further west with the mean trough axis, which would set up for potential for more mild temp pushes and rainer potential as well. The GEFS are further east with the mean trough axis, and would favor a cooler scenario temp wise with more snow chances for more as well. We'll have to see if there's a trend towards either solution this week,
