Update for Today's Storm

By: BwalshNLWeather , 11:41 AM GMT on January 29, 2014

Good morning,

A chilly start to the day across Newfoundland, setting up the first snow storm in almost 4 weeks for the Avalon and Burin Peninsulas later today.

Little change in the overnight models in terms of timing and amounts for Eastern Newfoundland, so the timeline is just slightly revised below.

Flurries develop later this morning, intensifying through the afternoon before tapering to flurries by midnight. The highest snowfall amounts will be on the Avalon Peninsula where 15-30 cm is likely by midnight. As temperatures will be cold during the storm, the snow will be light and fluffy, which will accumulate faster. Winds won’t be a significant issue; gusts 50-60 km/h are likely this evening. However, with snow being light, significant wind speeds aren't required to produce reduced visibility in blowing snow. Driving conditions from mid-afternoon through late evening will be hazardous on the Avalon with moderate to heavy snow and occasional blowing/drifting snow.

Timeline for St. John’s and the Northeast Avalon:
Wednesday 9 AM – Noon: Flurries developing (Trace amount). Light winds.
Wednesday Noon – 3 PM: Light to moderate snow (2-3 cm). Wind southeast 20-30 km/h.
Wednesday 3 – 6 PM: Moderate to heavy snow (5-7 cm). Wind southeast 25-35 km/h.
Wednesday 6 – 9 PM: Heavy snow (5-8 cm). Wind east 30 gusting to 50 km/h.
Wednesday 9 PM – Midnight: Snow tapering to flurries (4-6 cm). Wind northeast 30 gusting to 50 km/h.
Thursday Midnight – 6 AM: Flurries ending (Trace-1 cm). Wind northwest 20-40 km/h.

Newfoundland Snowfall Totals (through noon Thursday):
Avalon Peninsula Southeast: 20-30 cm
Metro St. John's and Avalon Peninsula Southwest: 20-25 cm
Avalon Peninsula North and Burin Peninsula: 15-20 cm
Clarenville, Terra Nova, Bonavista Peninsula and Connaigre Peninsula: 10-15 cm
