It's going to be a warm start to the week!
A weak storm will brush by Northern Utah and bring a cold front late in the day. Showers & thunderstorms are possible, mainly close to the Idaho border. It'll be a slightly cooler behind the front as it makes it's way across the south tomorrow. More showers could pop up along and over the mountains.
It'll be sunny and warm back up as high pressure rebuilds over Utah later this week.
