Warnings
This is a warning that at or near zero ground temperatures will cause frost in the parts of these regions. Monitor weather conditions..Listen for updated statements.
A ridge of high pressure continues to lie across parts of Northwestern Ontario. Some clearing from last night has allowed the mercury to once again dip to near the freezing mark. Consequently areas of fog have formed. Fog is expected to dissipate shortly after sunrise.
Current indications suggest that conditions may be favourable for frost formation over parts of Northeastern Ontario tonight into Friday morning. A frost warning may be re-issued later today as required.
