Major pattern shift is underway over the next few days...one that will lead to quite mild and mostly dry weather for at least the next 2 weeks...perhaps longer. Possibly a storm threat or two...but wouldn't be of winter weather concerns if they happen. Can't completely rule out a March Surprise (like an ULL-type system) but the pattern for the remainder of the season doesn't look to be supportive of the synoptic-scale winter storms in the South we've seen for the last month.
This is bad news for the lingering drought conditions over the Southern Plains, Mid South, and Southeast U.S: http://www.drought.unl.edu/dm/monitor.html I also heard on a farm report last weekend, that while it has been snowy across the Plains, the snow has been an unusually dry snow (much like what fell in the recent event). In fact, it was stated that much of the snow on the ground has about 50% of the water content of what is "normal" for the Plains. Going two weeks in February with no significant precipitation is very atypical for our area, and I hope it's not a trend that continues into Spring. We need some decent late winter storms to wipe out the deficits before we get into the warmer months, and planting season.
James Spann mentioned that the NAO is currently forecast to go neutral toward the end of the month.
GFS has a huge ice storm around the 23rd/24th for Nashville and Huntsville, with almost an inch of ice. Haven't checked outher places, but, ugh.Edit: Memphis definately would be hammered too.
This late in the season, I'm not sure a neutral NAO would help us...UNLESS we had some very strong ridging along the west coast. It'll also be harder to hold off the SE Ridge given that we're heading into late winter.
Can't rule out some cool or cold snaps, but my guess is that the GFS is dealing with its cold bias in the long range at this point. I have a feeling the next few weeks will be more like the business as usual winters we had seen in previous years, unless the AO/NAO come back around to what we had been seeing for most of this winter.The GFS will show its 300+ hour storms only for us to see the moderation as we get closer in time, mostly likely, in my opinion.
