Why does Arizona have such a fast weather change?

was thinking it was a good time to plaint seeds and flowers 80 tepts now in the 50's feels like snow.

Well you see, temperatures don't change much more than one or two degrees as a yearly average. That's what decides of our climate. But within a month, a week or day, temperatures change wildly depending on so many different factors. if, for example, you have a high pressure west of your position, and a low pressure east, it will pump polar air in your region. If the opposite, it will pump tropical air masses. All this is rather attenuated by big bodies of water like the oceans but ... while I live in Norway and don't know much about Arizona, I think you have a typical continental climate; it changes fast. Good luck with your flowers. Whatever it looks now, springtime will come!

I talked to my sister who lives in Phoenix thisa.m. she told me the high today would only be in the 70's although a week or so ago it was in the 80's. Since I'm going there on Tuuesday She figured it would be back up into the 80's but they don't want really hot weather too soon or 100 won't be far behind which can make for an extremely hot summer.

Because there is a low pressure system in the southwest right now that is causing 50 degree temperatures. I am in Surprise Arizona right now for Spring Break with my girlfriend
