Reply to comment by ballsonthewall in can someone meteorologically explain why snow is adverse to pittsburgh or does mother nature just not want to see us pgh skiers happy? by d071399

Do the rivers converging have anything to do with this as well?

not really. what most people don't think of is that weather is 3D, rather than a plot of rain and snow on a 2D map. layers of warmer and colder air in the upper atmosphere are far more pertinent to what precip you see at ground level than anything happening on the surface. that's not to say small variations caused by local microclimates don't make a difference in observable weather, rather that they aren't going to change the whole metro area's weather like this dry slot did.

That makes sense. Like you put it I never really gave the 3d model a thought, especially with the different layers of air currents and hot and cold zones.
