Well, after all the talk about the chance of snow for this weekend in the interior Northeast, it turned out to be mostly just model error…but kudos to the European model which did a fairly decent job in calling that this would mainly be a Lakes/Midwest beast. Something is just inherently wrong with the GFS that it can’t handle certain things well…especially interesting considering the ensemble track was south and east even of the model. Let’s discuss what’s up.
First the blizzard. Just massive. Most of you know about the Metrodome roof collapsing under the snow (not unprecedented, but they aren’t going to have that place ready for a game tomorrow). More details on the storm’s impact in Minnesota here.
Storm total at MSP is 17.1″, making it the fifth largest storm on record for the Twin Cities.
Storm totals were as high as 23″ in Polk County, WI, 21.5″ in New Market and Shakopee, MN, 21″ at Oakdale, MN, and 20″ at Red Wing and Maplewood, MN.
Blizzard Warnings remain in effect today from eastern Iowa to the NW suburbs of Chicago and Milwaukee and N Michigan. Winter Storm Warnings are posted for Wisconsin, Illinois, Michigan, parts of Ohio, and the Appalachians from PA to Tennessee. And Winter Weather Advisories are posted all the way into far N Alabama and Georgia! On top of that, freeze and wind chill warnings/advisories are posted for the Deep South all the way into southern Florida, where nighttime lows early this week are going to rival what we saw back in January. Another round of lake effect snow is going to hammer Central and Western New York again this week (though to me the trajectory looks a little more northerly than what occurred last week, which would mean less snow for places like Syracuse). But we’ll see.
Overall, winter is in force in the Eastern US. At the same time, we’re going to break record highs today across SoCal, with widespread mid 80s expected. Amplification…what goes up must come down…strong, deep trough in the East = strong ridge in the West usually. And we are in an extremely amplified pattern…and the anomalous nature of this amplified pattern is going to remain in place for the foreseeable future. That means more fun to come.
So what do I think is to come?
We have a couple systems to watch. With extreme blocking in place, the storm track is going to look a lot like last winter. One weak wave looks to pass through the southern US Wednesday night-Thursday night. It’s a flat wave though, so I question if other than some nuisance freezing rain or sleet if it will pack much punch. It will serve though to reinforce the cold over the East for next weekend.
A more important storm is evident on the European model for the end of the weekend or early next week. This shows a more amplified storm, which if taken literally, shows a substantial snow chance from the Carolinas to DC and possibly into New England. The GFS isn’t showing much other than a cold pattern right now and keeps everything offshore (not uncommon for this model to miss a feature like this though). I am getting somewhat on board for at least the threat of a snow/winter weather event in the Mid Atlantic and possibly the Northeast next weekend or early Christmas week.
The pattern is active later this week with a 140+ kt jet stream pointed right into California. This isn’t too unlike what we saw a lot of last winter in the active El Nino pattern. Whether this is too far north or not, I guess we’ll see, but with a load of blocking in Arctic/Greenland and a load of moisture/energy slamming into the West Coast…that to me suggests someone in the East is in for it at some point. It still could track out to sea…it still could track inland…it may be the model misleading us. But it’s evident that the weather pattern is much more intriguing than it has been. We’ll watch this week and see!
Couple things to round this out…
First, if you missed it at all, here’s the incredible video of the Metrodome’s roof collapse in Minneapolis:
Lastly, if you like Google Earth, and if you like hurricanes, here’s a cool post with links to great visualizations of the hurricanes from this past season.
