(10 h 00) As of 10 am, about 11 cm of snow has fallen at our station. More snow flurries this morning. Impressive for a late-season clipper!

[Ottawa West Weather Station météo d'Ottawa O. @OttWeatherMeteo]

(0 h 15) Unlike what some models were suggesting initially, temperatures seem to refuse to climb above 0°, which might mean some ice accretion is here to stay for the morning commute.

🔶🧊 Orange Freezing Rain Warning is still in effect.

🧊Freezing Rain event ongoing in Ottawa

Temps consistently below 0°; 0 km/h wind readings due to ice build-up on anemometer (circled) are signature signs of a freezing rain event.

Accretion seem modest so far. Judging by formed icicles, on track for 10-20 mm as forecasted.

@julienalla11333 A bit. Seems to me that most are indicating around 15-25+ mm. Slight downward trend in the last runs of GFS/NAM.

[Ottawa West Weather Station météo d'Ottawa O. @OttWeatherMeteo]

Significant ice risks in Eastern Ontario and southern Québec Wednesday.

Models consistently showing 15-30+mm of ice accretion for Ottawa, starting Wed morning into late evening.

Long duration+high accretion+wind, likely high impact event. Will monitor.

#OttWeather #ONstorm

[Ottawa West Weather Station météo d'Ottawa O. @OttWeatherMeteo]

At the forecasted ice accretion of 15-30+ mm ice accretion, slippery roads, fallen tree branches, and power outages are all possible.

Consider rescheduling plans this Wednesday.

Line of moderate-to-heavy rain on its way for Ottawa arriving around 3pm.

We’ve received 23.6 mm of rain since midnight, and snow cover still resilient. Frozen ground, melting snow and heavy rain will cause water ponding on roads.

Yellow Rainfall Warning in effect.

@WxOntario1 Now a winter without thaws would have been nice and more memorable. This winter was meh in my books, especially with a lack of winter storms for the Ottawa region.
