There is also a risk of thunderstorms between 10 a.m. and 1 p.m., according to hourly forecasts from The Weather Network. Precipitation probability could reach 80 percent during the early morning hours. No weather alerts are currently in effect for the area.

After Wednesday, conditions are expected to improve. Thursday and Friday are forecast to be sunny, with highs of 26°C and 27°C respectively. Saturday will turn cloudier with a 40 percent chance of showers and a high of 26°C.
