Water vapour imagery this evening. A seemingly endless stream of moisture being directed into eastern NS. WV retrograding slightly westward as the parent trough takes a on negative tilt on route to becoming fully cut off. This process is what will allow snow to redevelop in HRM

For HRM most of the snow will fall tonight through tomorrow afternoon ~20-30cm. Then there will be a break in the snow Saturday night that will allow for clearing etc. Sunday another round of snow ~10-15 cm with stronger winds and blowing snow. Event totals ~ 30-45cm. #NSstorm

Biggest issue with up coming rainfall will be the vast majority of it falls in 3-6 hrs. Rainfall rates will increase the risk of flooding. Normally a rainfall warning is issued for 50mm in 24hrs or less, we could see that in 3 hours or less. As illustrated below. #NSstorm

Can't take upcoming storm at a 10:1 SLR verbatim especially northwest of YHZ. Too much vertical motion 700-500mb through a deep DGZ after midnight Monday. Strong frontogenesis, snowfall rates 5-10cm an hour likely. Luckily it's a fast mover. #NSStorm

Just spotty showers today; but rain developing N NB. A N-S band of rain with t-storms moves into western areas tonight crossing eastern areas Wed. 30-60mm N & W NB with 15-30mm south. Thunderstorms will add ~20mm (so risk 80mm total N NB & 50mm Atl coast NS). More rain Fri.

Thoughts on upcoming system: usually significant freezing rain that can lead to power outages is limited to localities well outside the urban core towards YHZ-Hammond's plains. 300-400ft of elevation often the difference between very little icing to significant impacts. #NSStorm
