01 May 09Z (5am ET)–17Z (1pm ET): ceilings lift and skies clear behind the warm front; CYTZ TAF shows SKC from 06Z (2am ET), CYYZ SKC from 06Z (2am ET), CYOO expected VFR mid-morning through ~17Z (1pm ET) before showers return.

CYOO is currently VFR with an overcast at 13,000 ft and winds from the NW at 10 kt, but the region is transitioning through a complex post-frontal pattern. The GFA CLDWX charts show a warm front lifting through eastern Ontario by 06Z with freezing drizzle (FZDZ) and low ceilings, while a secondary frontal trough approaches from the west by 12Z. Southern Ontario near CYOO will be VFR-to-MVFR through the overnight, improving by mid-morning, before shower activity returns Friday night. The icing and turbulence GFA shows freezing levels near the surface in some areas and moderate icing possible in cloud.
🤖 AI summary — verifyConfidence decays with distance — days 0–1 are TAF-backed, days 2–4 rely on a single-model extended forecast, days 5–6 are a directional trend only. Lower-confidence days are dimmed.
VFR now, overcast 13,000 ft; warm front nearby with FZDZ risk overnight
Clearing to SKC/FEW by mid-morning, best VFR window ~09–17Z, showers return PM
Shower activity likely; broken ceilings and SW winds, MVFR periods possible
Light rain, WNW 11 kt gusting 20; MVFR ceilings expected
Drizzle ~9h, S 14 kt gusting 26; IFR-to-MVFR likely through much of the day
Drizzle continues, WSW 13 kt gusting 31; gustiest day, MVFR-IFR
Fog risk with light E winds; overcast, low-confidence trend only
At 00Z (civil dusk), CYOO is reporting VFR with an overcast layer at 13,000 ft, winds NW at 10 kt, and 9 SM visibility — a reasonable end to the evening. The GFA CLDWX 00Z chart shows patchy freezing drizzle (FZDZ) and low ceilings (3 AGL in layers) moving through the Ottawa Valley and eastern Ontario, with the warm front positioned over that region and pushing slowly northeastward. Overnight into early 01 May, the post-frontal flow keeps most of the Toronto/Oshawa corridor in broken-to-overcast cloud but above MVFR minimums; the main hazard is potential light freezing drizzle if the warm front nudges westward. By 06Z the GFA shows clearing beginning in the west as the system exits; civil dawn (09:37Z) should bring improving VFR conditions at CYOO.
1 May brings the best window of the short-range period. TAFs for CYYZ and CYTZ both forecast SKC/FEW from roughly 06Z through the mid-day, with CYYZ calling FEW at 6,000 ft from 12Z and light showers not until 21Z. CYOO should follow a similar pattern: a clear, light-wind VFR day from mid-morning through mid-afternoon, with winds veering SW 5–8 kt by afternoon and ceilings building back to broken at 5,000–6,000 ft. The GFA CLDWX 12Z chart confirms improving conditions across southern Ontario with patchy snow showers confined well to the north. The GFA TURBC 12Z frame shows the freezing level rising to 5,000 ft over the CYOO area, so icing in any residual cloud layers remains a consideration for climbs above 4,000–5,000 ft ASL in the morning hours.
