A quiet overnight. Friday's storm is the one to watch.

Alberta — Highway 2 (QEII)

QEII: mostly dry overnight, calm before Friday

The Calgary–Edmonton QEII (Highway 2) ran mostly dry overnight with no closures or incidents reported — the 511 corridor read showed a lowest overnight temperature of −1°C and winds to 20 km/h. Environment Canada's direct pages for Edmonton and Calgary both showed no alerts in effect as of the early-morning check, and observed readings were −1.1°C at Edmonton Blatchford (1:00 a.m.) and 2.5°C at Calgary International (5:00 a.m.). Tonight EC's Calgary forecast calls for rain mixed with snow overnight with a low of plus 2°C — the calm before Friday.

Alberta — Highway 16 (Yellowhead)

Yellowhead: dry overnight, snow arrives at the Jasper end tonight

The Yellowhead (Highway 16) was also mostly dry overnight with no closures or incidents reported — the corridor read showed a lowest overnight temperature of 3°C and winds to 11 km/h, with no EC alerts in force on the direct Entrance-area page. At the Jasper end tonight, Environment Canada's forecast calls for rain changing to snow in the evening with the snow level lowering to valley bottom and 2–4 cm possible, low minus 1°C. Willow Creek in Jasper National Park dipped to −3.1°C overnight — the cold air is already sitting in the valleys.

British Columbia — Highway 5 (Coquihalla)

Coquihalla open — two work zones through Oct 24

Highway 5 between Hope and Kamloops stayed open to through traffic overnight with no incidents reported. Two work zones are in effect through Oct 24: lane closures at the Nicolum Creek Bridge (one direction at a time) plus paving-related lane closures in both directions near Box Canyon and Coquihalla Lakes, with an electrical maintenance right-lane closure today. Fog patches were reported near Blue River on Oct 21 morning — north of the Hope–Kamloops core but worth noting for trucks running the full Highway 5. No chain-up requirement is posted; the standing BC chain season (winter tires or chains on designated mountain routes since Oct 1) remains in force.

Ontario — Highway 401 (Windsor–Toronto–Kingston)

401: quiet overnight, one minor disabled-vehicle item in Toronto

The 401 corridor was quiet overnight: no major incident on the Windsor–Toronto–Kingston run could be verified from a reputable source. The only current item is a minor one — a disabled vehicle on the 401 eastbound collector at Keele Street in Toronto, right lane and shoulder affected, timing unverified. Toronto camera aggregators showed mostly clear flow with a few slow spots and work zones. Environment Canada's alert status for the Ontario corridor was not directly verified this morning — check it before rolling.

Prairies — Alberta & Saskatchewan (incoming)

Incoming: Friday prairie storm, slow QE2 commute

A blast of wintry weather is moving into the Prairies tonight and Friday — up to 50 cm for northern Saskatchewan and Manitoba by Friday evening. Closer to home, the Weather Network warns of a slow drive to work on Friday morning along the QE2: Friday-morning rain changing to wet snow with gusts of 50–60 km/h. That is the window that turns today's quiet QEII into Friday's problem — tonight's Edition No. 3 is where the storm story lands.

Bottom line for drivers

Nothing closed overnight — the hazards are still the quiet ones: frost on bridge decks, fog in the lows, work zones on the Coquihalla. Friday is the morning that matters: wintry weather moves in tonight and Friday's prairie commute is the one to watch — check 511 and Environment Canada before rolling.
