GHD III Winter Storm Possibility, Feb. 1st-3rd

Recommended Posts

I do hope Nebraska and western Iowa folks can put away a historic snowstorm for the books. Need to watch the GFS, CMC, and EURO to see how they handle the low structure.

00z NAM doesn't even close off the low at 500mb like the other models...

 

This..... Compare the 12z and 00z nam.  The 12z has a big closed H5 low, while on the 00z run it's totally gone.  Hence, the weak surface low and eastward slide.  It's real tough to buy what this run is selling.

Once the NAM gets under 48 hours, then it starts getting better. Right now we're just beyond that.

No it was me, but you're welcome.

If you read some of his earlier posts, you'd understand why I'd say that. The dude said that DC would get "light accumulations" from the blizzard last week. Then he says that this would be a KC and Chicago special earlier today without providing any meteorological data to support those asinine calls. Now he's saying that this will trend SE because of one NAM run at hour 66?

No, it wasn't me Maxim.

 

I'm gonna see what WGN has to say about this.

It's really not that hard to ignore the stupid posts. At least we don't have Tim the weatherman back on here talking about every storm bringing a blizzard.

True, but still, it makes the board look bad with all these trolls just spewing out nonsense.

 

Completely forgot about the ignore prefs feature too... I'm sure I might have to use that at some point.

Ramsey saying snow to mix to rain, then back to a little snow for Chicago proper. He did stress it could produce more snow.

1 mb stronger

hence the words "appears" and "slightly". 

 

Because I'll be the first to admit I'm no expert when it comes to this and the only way to get better is watch more and more storms.

Not really sure why he thinks this is going to start out as all snow, though.

 

He said there will be some cold air out in front of the system. Every model is showing it.

1mb stronger or weaker isn't really a big deal.  Just noise and crap. 

at first glance it looked like 2mb stronger to me, but that's why I post so I can get criticized about every thing that I'm doing wrong.
