Outdoor wedding in Salt Lake City Utah 10/10/2020

Outdoor wedding planned for October 10 2020. What can I expect from the weather and what time is sunset?

wedding November 1

Planning a wedding November 1 Portola, CA 4:00 Pm how does it look for outdoor ceremoney

warm rains

I live right on the Nampa-Caldwell border, and we got a couple of incredibly warm showers today, with some cooler night showering last evening. Today’s rain was accompanied by bright sunlight (smoggy even still by the California fires going on right now), and it was about 88 degrees outside. Humid, too.

Region 13

I live in Southeast Idaho, right on the Northern Utah border. Since I’m right in the middle of the Intermountain region I’m not sure which forecast to follow...north or south?

July and August

This has been the hottest summer yet. Temps in the high 90s and into the 100's. No rain. I read one report that we have had 2 inches of moisture this summer. Now mind you, this is central Utah. But if we don't get a huge snow pack this winter we are in big trouble. Animals are suffering from the heat. I am trying hard to keep my goats and sheep comfortable. Global warming is real, we have spoiled our nest.

Weather in Kuna

I live just outside of Meridian and the forecast will have thunderstorms or rain. When it gets close to us, it just fades. Is there something that prevents the rain from reaching us? We call it the Kuna Circle. All the bad weather just surronds is and fades?

wedding 10-10-20

we are getting married on October 10th of this year. ceremony is outside should I be worried about rain and snow?

November 7th Wedding

We are getting married on November 7th. Ceremony is outside and starts at 5. Everything else is inside. What are your weather predictions and do you think it will be light enough for a short 20 minute outdoor ceremony?

Rain

Finally, we are getting some rain, I hope it keeps up throughout the summer. So far the Almanac has been correct with their weather forecasts this month.
