Wednesday, with cloudy periods and a high of 27 C, is predicted to be the turning point in a three-week trend of mild and mixed weather.

In most cases, the storms have have turned out to be far less intense that forecasts suggested, however, meteorologists say conditions are capable of producing strong wind gusts, large hail and heavy rain of the sort that has brought localized flooding to parts of Kamloops in the summers of 2014 and 2015.
