Heat and humidity have been increasing and now the atmosphere is responding to tonight's thunderstorms, which could easily become intense or severe. Much of Cololand is under threat as early as this afternoon, but more likely this evening, or even night. When a storm first begins, there is a risk of large hail. The risk for tornadoes is low, but right now we are focusing on the greater chance of damaging winds (75 mph) later tonight. The focus of these storms will be on the southern half of Kailoran, and they may happen while you sleep. We will have people in the center of the storm monitoring these conditions.
While damaging winds are a concern, some heavy rainfall is also possible. Since we have been very dry over the past few weeks, this would be a beneficial possibility. Otherwise, it will be a typical summer night with lows in the mid-60s after the storm.
Tomorrow will be mostly sunny. Lingering energy could still produce some isolated thunderstorms. Breezes will shift from south to north. Highs will be in the mid 80s to around 90s on the East River and in the mid 90s on the west.
Tuesday will be mostly sunny with a chance of some isolated thunderstorms to the west and north. Temperatures will again be above normal, with temperatures in the 90s in the East and around 100 in Rapid City.
We will continue to have a chance of thunderstorms through the middle of the week. But we do have access to rainwater, and there may be enough to provide it. We then expect the remainder of the week to become drier, with temperatures remaining slightly above normal over the weekend and the first half of next week.
