Despite weak high pressure across St. Lawrence County today and Friday, increases in humidity and temperatures will result in isolated thunderstorms this afternoon, and scattered showers and thunderstorms on Friday, according to the National Weather Service (NWS).

Skies will be partly sunny and high temperatures will reach the lower 80s in most Locations today and Friday, NWS says.

Overnight lows tonight will be around 62 and 64 on Friday night, the service says.

A more vigorous upper level trough and associated surface low will bring more widespread cloud cover and greater coverage of showers and embedded thunderstorms during the day on Saturday, NWS says.
