To A-L-E-K .... saying this in fun, if you are depending on psychic powers to be right, chose something other than weather! Coin toss would be the way to go :)

 

I won't speak for Alek's credentials, but I will say from being on weather bulletin boards with him for many years that he has a very good understanding of meteorology and sometimes weenies here disagree with his conservatism.

To determine a particular models performance, compare the new update cycle 00 hour image with the previous cycles 6hr forecast if it is a 6 hr cycle, or compare the new cycle 00 hr image with the previous cycle 12hr image if it updates on a 12 hr cycle.  

 

Also with forecasting, trend is rarely wrong.  It is getting location and timing right - that is where people can make money :)

He's got model support from that from nam/gfs/rap he's just not making up stuff, sure the data COULD be wrong but its hard to ignore it and you can be a snow lover as you want but you have to be real and fair with your accumulations.

The late Friday system was a bust here with little more than a trace of snow.  The good band parked all afternoon and evening from Ames to Waterloo and dropped 3-4 inches there.  I don't know what the heck to expect today.  There have been plenty of model runs that dropped real nice snow, but the Euro has become very dry and the other models have slowly backed off as well.  It may be just another 1-2 inch event, which would be an incredible disappointment given what the models have shown for the last week.

To Winterfreak -- the atmospheric sounding forecast above you, this is for KC metro area, shows the inversion is up at about 7,000 ft.
Thus, you will get either ice pellets (raindrops will already freeze) or snow, but don't see freezing rain or icing.  By 50 miles south of KC metro area, appears freezing rain icing more likely.  You can use the RAP forecast products here at AmWx.  Be safe ~

HI all, if people are here to guess on the weather, that is good.  If people are here to learn about weather, do more with their lives as a result, that is good, too.  Just figuring out the two camps.  Just difficult to see people prognosticate from erroneously trending data and possibly lead others into thinking its accurate.  That is actually dangerous!  

 

Beyond 12-24 hrs the NAM, SREF, WRF and often the GFS are completely in error on warm air advection winter patterns like we have seen now.  The ECMWF and then the RAP are always best. Thank you.

Dude most of us are here to just has some fun.  Most here are we weather geeks & hobbyists.  We love to look at dream model runs and for the most part know it is just model porn!!!

 

Several people on here have been posting together on various forums for over 10+ years ... we harass, tease and joke A LOT.

Tried to add RAP sounding image for KC area for this afternoon.  The above freezing area is way up at about 8,000 ft.  This favors ice pellets and snow mix, not freezing rain and icing.  Trend is then to all below freezing at all altitudes favoring snow.

Data from AmWx RAP sounding. Be safe ~

A bowler's worst nightmare.

 

You have a shot that I could use to pick that up? :lol:

 

Hopefully Hoosier doesn't get too upset with me, but I'm gonna go with 3-5" for LAF. Riding a 12z GFS and NAM compromise with that call...because the others (RGEM, UK) so far, are pretty ugly for here.

Tonight we should see a fairly quick 3 inches of powder. Its interesting how many times and ways the evolution of these waves have changed. Oh well, should beautify the ancient snowpack. Wish it would hold off til after midnight, but it wont, so cant be choosy lol.

If my flakes (very powdery) are like they were this morning I think 3" is definitely achievable.
