2/4 - 2/7 Multi-Wave Storm System


Tom

Recommended Posts

Alright guys, as we gear up for a Big sporting event this weekend, will we also be gearing up for a potential snowstorm early next week???  After a brief spike in temps across the majority of our Sub this coming weekend, the pattern will turn more wintry as cold air will begin to press its way south coupled with energy that will eject out of the Rockies and the Baja of California.  

 

The models are struggling if the energy that comes out of the Rockies in one piece or if its a weaker piece and a secondary more potent wave develops a couple days later.  The GFS is the only model that is suggesting a more progressive pattern and has the energy come out quicker while the GGEM/EURO hold back and develop a stronger second wave a couple days later.

 

Let's dive in...

Glad you got a thread up bud! Perfect timing. I think we sit well for once.

 

Go Chiefs!

My office is keeping it short and sweet this morning.

 

Super Bowl weekend will feature near zonal flow aloft with
southwesterly low level flow bringing in warm temperatures with
50s and 60s likely on Sunday, a cold front will setup across far
northern Missouri so cooler readings possible up north.

Models continue to show a potential winter storm on the horizon for
late Monday through Wednesday. Still too early to get into the
details. This could impact any potential Super Bowl celebrations
across the Metro area early next week. Stay Tuned...

I got the Chiefs in the Superbowl and a storm to track, this is better than Christmas!

 

IF both "Big Dance" and models trend favorably, indeed it will be! Best of luck on both buddy!

From OAX forecast:  

Tuesday

A slight chance of snow. Mostly cloudy, with a high near 28.

 

 

 

From the OAX discussion: 

Monday through Wednesday:
The strong shortwave will strengthen and move from the Pacific
Northwest over the central CONUS. Confidence is low on exact
details beginning on Monday. It is likely there will be a
significant cool down Monday with high temperatures about 20
degrees cooler than the day before. The system should produce
significant precipitation somewhere in the central CONUS, but
medium term guidance varies greatly in timing and location. Cool
temperatures should be long lived as temperatures should moderate
at the end of the forecast period.

Euro with a "Beast" just to my east! Slams SEMI and Niko/Matt. Could be a little bit NW for kismet here. Verbatim tho, it would be an excellent deja-vu event for the 2004-05 analog.

So we're looking at yet another nice upper trough ejecting into the central US, but then gets sheared out.  What's new.

Being this far out, I don't think LOT could hav written their AFD any better. 

 

Not worth spending too much time talking about the post Monday
time frame. The possibilities run the gamut from no storm system
affecting the area in the GEM, to a potential shovel-able snow
maker, to icy mix, to maybe just rain. There is some clustering
in the
ECMWF ensembles for a surface low in eastern IL/western IN
by Tuesday night, so the GEM`s nothing solution seems unlikely.
Beyond that, really no sense in getting into potential details.
No changes made to NBM which has chance
pops through the
potentially problematic time frame with some transition from rain
to snow. Certainly the Tuesday/Wednesday time period bears
watching next week.

Looks like someone will get a good snowfall. How far south does the cold air sink? What will be the axis of the 500mb trof? Will the main energy come out all at once or in two pieces?

12Z ICON gives Nebraska a 3-6" snow depending on location.  Heavier in the west and southwest according to Tropical Tidbits.  Looks like my area is a general 3-4".  There is going to be a stripe of snow someplace across the plains, question as always is where does it set up and does it want to split apart.  Many questions remain in imo.

Should I have been banded, probably. When I get board, I listen to music....

 

Love this pattern. Pivot point looks south of lake Erie. Is this the final sullusion u. No.

Thin stripes of snow like that this far out tend to not end well

^^^ I'm not savvy wrt the 500 mb Vort maps, but that looks potent as h*ll to my untrained eyes!

 

 

Meanwhile, GRR coins a new term for our model woes.. :lol:

 

-- A signal remains for some snow mid next week --

The system for mid next week remains in the models both the
deterministic and the ensembles. The shortwave in question is in
the middle of the Pacific Ocean with a long way to go before it
interacts potentially with our area. Models will continue to
bobble
north and south with a swath of snow before it zeros in on
a location. The time frame of concern is next Tuesday and
Wednesday. The operational GFS is quicker and further north with
the snow and the Euro is slower and south. Bottom line is we have
many model runs to go before this is a concern. Some of the models
are trying to merge the northern and southern streams which would
lead to a deeper slower low like the Euro.

If you look actually looked at the run you would see it splits the storm in several pieces weird run for sure.

 

Well, maybe we are about to see the 2014 analog trotted out? Seems like whichever model takes whatever trajectory, they mostly converge to a decent hit for SMI. Too far out to count on much, but as posted earlier, I think we sit well with this one (ORD > DTW crew).

I think you do also.  You seem to get at least a descent hit no matter how the run goes
