Nova Scotia weather links

Here I am just going to list and update the most useful links I can find for Nova Scotia weather. I'll update as I find additional links. If anyone reads this and has some good links please share :).

Some basics:

Worth remembering 0 Celsius = 32 Fahrenheit for those used to C looking at F plots. 

Key sites:

Current surface analyses:

Radar:

Current radar:

Lightning

Model forecasts:

NCEP GFS and other models:
RAP, NAM, and GFS from rap weather:
Snowfall forecast:

Written forecasts/discussions:

Halifax (Shearwater) I guess this is the best for Halifax since it is by the coast, unlike the airport.

Surface observations:

Snow on Thursday morning in Halifax?


Thursday 4 Dec update: The post below (written on Tuesday 2 Dec) shows how wrong I was and how right the Environment Canada forecast was. No snow at all fell on Thu morning and it was fairly sunny. I will need to refine my forecasting skills a lot.

----------------------------------------------------Tuesday post below---------------------------------------------
Currently a low pressure is forecast to develop over east Canada over the next couple of days. My question is over the forecast. Environment Canada says for Thurday's weather that it will be "Sunny". The GFS suggests precipitation and the 540 and 528 thickness lines will spread across Nova Scotia brisk WSW flow by 500 am on Thu (shown on image below). To my eyes this suggests a fairly decent fall of snow but I have only looked at the GFS model. Perhaps environment Canada just keeps it simple a few days out as it may know how tricky the forecast is in the this area of the globe. We shall see. The precipitation does clear but not until Thu afternoon in this model.
