Ottawa is starting Saturday, October 3 with clear skies, 6.6°C and a light northwest wind of 10 km/h gusting to 32, with humidity at 85 percent as of the 9:07 a.m. UTC observation at Ottawa Macdonald-Cartier Int'l Airport. Today's forecast calls for sunny conditions once morning fog patches dissipate, with a high of 15 and a UV index of 4, or moderate. That high matches the seasonal normal for today, which sits between a low of 6 and a high of 15.
Today and Tonight
Sunrise was at 7:03 a.m. and sunset comes at 6:40 p.m., giving Ottawa just over 11 and a half hours of daylight. Once the fog clears this morning, skies should stay sunny through the afternoon. Tonight turns clear again, but fog patches are expected to develop overnight as temperatures fall to a low of plus 3, with a risk of frost. Anyone with sensitive plants still outside may want to cover them before bed.
The Next Few Days
The sunny stretch doesn't last. Sunday turns mainly cloudy with a 40 percent chance of showers in the afternoon, though morning fog patches should dissipate first. The high climbs slightly to 17, with a UV index of 4. Sunday night stays cloudy with that 40 percent shower chance continuing and a low of 8. Monday brings a mix of sun and cloud with a lower, 30 percent chance of showers and a high of 13, cooling off Monday night to a clear low of plus 2.
Getting Around
With fog patches forming and dissipating on both ends of today and tonight, drivers heading out early this morning or late tonight should watch for reduced visibility, especially overnight once temperatures drop toward frost. Tonight's frost risk also means a possible icy glaze on windshields and exposed surfaces by early Sunday morning, so budget a few extra minutes for a scrape before heading out. Sunday afternoon's shower chance could make for a damp commute home, and that pattern lingers into Monday with a lower but still present chance of rain. There are no active weather warnings, watches or statements for Ottawa at this time.
