Weather in Yellowstone

We plan to visit for 4 days during the memorial day weekend. I understand that it can be much cooler in higher elevations. We are not hiking/camping. We plan to drive around mostly during the day. Do I need to bring a winter jacket too (30s-40s F) ? Can I assume the weather is going to be above 60s most of the time ?

Look at the weather forecast before you come. We were there in 2007 and it was warm and sunny and in the 60's and came back in 2008 and it was cold and snowing.

Here is a link to weather conditions over the years- this was last year's data but info from previous years is included-

I find, rather than a heavy winter coat, lots of layers work best, thus being able to adapt to any temperature by putting on & taking off layers as the weather can change abruptly:

base layer; wool sweater or shirt; fleece jacket or vest; waterproof -breathable jacket with hood; warm hat; sun hat; & thin gloves.

If you look at the Top Questions for Yellowstone, DE Voyaging has a great list for "What Should I Pack for YNP"

It snowed on me last year this time period!

Have fun planning!

It's possible to get a wintery squall that time of year but not so likely. A medium or light jacket should be just fine. We were there yesterday and even with lots of snow still on the ground, a winter coat would be way too much. The air is warm, the sun radiant and unless you just happen to hit a strong storm then you'll be very comfortable in lighter clothing.

I second what denalicat said about layers. I wpould add raingear.

It would be unwise to assume anything about the weather in Yellowstone in May.

Not a good assumption. Mountain springtime. Could be beautiful 70's or a blizzard or anything in between. On my June trips it snowed the second or third week a third of the time. Snowed on in dog days of August.

Dress in layers, rainwear.

We were there this weekend and temps varied between

mid 50s near the lake to low 70s near Mammoth. That being said I agree with wearing layers and expecting anything but a winter coat may be a bit much. Don't forget sunscreen!
