Did I ever say a decent snowstorm? I just said don't model hug any model right now.

Models have been trending warmer? Which one? Most likely it will be snow to rain but it's only Wednesday.

ECM & GFS...

I do not even bother to truly look into the GGEM....

The two major models have been trending warmer..mid levels...and even surface...

The mid and low levels continue to trend warmer (not the boundary layer quite yet) during the period of potential wintry weather on the front end of the system. This is not a very favorable setup for our area..so whatever winter precipitation we can get out of it would be nice. Obviously the chances for something go up the farther north you are.

But you won't see 1-3" and even if my some miraculous event you do, it will be largely washed away but rain anyway.

Dude. Who cares? Honestly, if he wants 1-3 then let him be happy. i just dont get why you post?

I mean im not expecting a lot of snow, but we all agree that anything is welcome.

It was said on this board recently that the negativity needs to end, but just trying to prove to someone that their snow will be washed away is pretty negative and lame.

Im happy with a ****ing dusting. Are you going to rip me now and say, well my dusting will get washed away?

I will also be happy with a dusting. The GEFS are cooler than the op but sligthly warmer than the previous run.

Well, if you get one, it will be. I am usually very optimistic but seeing a bunch of wishcasts isn't any better and is (obviously) making me bitter.

I'm not sure what you're seeing as a wishcast. It's not like snow that is washed away by rain doesn't count as snow.

Obviously but when people say the models haven't trended warmer, or "oh its 3 days away it will change" is certainly wishcasting. I really do hope it snows but come on, look at the pattern and look at the models, other then NW burbs I think there isn't much hope to be had.

Once again in the11-15 day and beyond, the PNA may become increasingly -. If that happens, we need to watch up north, as the NAO will try to go negative too. I think you guys really should hope that happens, as it could be gradient city with the arctic cold out in western Canada again. Lets hope the -NAO happens, because we'll need it I think.

Oh so the cold and stormy pattern may only be 11 days away? Sounds familiar...wash, rinse..

Question: in Saturdays scenario what type of snow crystals would you expect if we did get snow, dendrites?

Temperatures should be in the range for plates when snow does fall.

When the air over a cloud droplet is supersaturated (relative humidity greater than 100 percent), the vapor pressure of the air is greater than the saturation vapor pressure on the droplet's surface. In such an environment, water droplets grow by vapor deposition; more water vapor molecules are condensing to the droplet than are evaporating from it. Greater supersaturation occurs in stronger storm updrafts because the process of vapor deposition cannot keep up with the decompressional cooling with ascent. Ice crystals in the presence of abundant cloud droplets are said to be supersaturated with respect to ice even though relative humidity may only be 100 percent. This is because the saturation vapor pressure over ice is less than that over water, allowing vapor deposition onto the ice.

I'm just tired of people trying to look at a model and trying to twist it into something more beneficial for snow, hoping it will "trend" better. I am usually overly optimistic with snowstorms but in this case its looking like a complete failure based on the general feel of guidance.

Definitely give it more time, because things have had big changes even within 48 hours.
