Residents of Windsor-Essex should prepare for a cool and unsettled start to May, as forecasters predict a mix of clouds, rain, and even the chance of frost overnight. The region is expected to experience fluctuating conditions typical of early spring, with temperatures remaining below seasonal averages.
Thursday Weather Outlook
Thursday will bring a dynamic weather pattern, with periods of clouds and rain interspersed with sunny breaks. The unsettled conditions are due to a low-pressure system moving across the Great Lakes region. Temperatures are forecast to struggle to reach the mid-teens Celsius, making it feel more like early April than May.
Overnight Frost Risk
The most significant concern for gardeners and farmers is the potential for frost overnight Thursday into Friday. Clear skies and light winds could allow temperatures to dip near or below freezing in some areas, particularly in rural and low-lying locations. Residents are advised to protect sensitive plants or bring them indoors.
This cool pattern is expected to persist into the weekend, though conditions may gradually stabilize as the new week begins. Meteorologists are monitoring the situation closely, as further shifts in the jet stream could bring warmer air later in the month.
