Pressure and weather in Tecumseh
Tecumseh faces Lake St. Clair on the flat clay plain of Essex County, at the southwestern tip of Ontario and on the same latitude as northern California, which makes it the mildest place in the province. Water surrounds the area on three sides, with Lake St. Clair to the north, the Detroit River to the west and Lake Erie a short distance south, and that envelope keeps winters shorter and summers longer than anywhere else in Canada, supporting a growing season long enough for a substantial greenhouse and vineyard industry. The weather arrives from the American Midwest rather than from the north. Summer brings deep Gulf humidity, with dew points that would not be out of place in the Ohio Valley and organised thunderstorm complexes crossing overnight. Winter is dominated by Colorado lows tracking up through the Ohio Valley, which frequently put the area on the warm side of the storm and deliver rain where places a hundred kilometres north get snow. Squalls off Lake St. Clair and Lake Huron reach the area on a strong northwesterly.
What this means for you
Systems here often pass on the mild side, so the same barometric fall that brings snow inland arrives as rain and heavy humidity. Reading a barometric pressure forecast alongside the dew point catches what pressure alone leaves out.
