Bracing for Another Big Pacific Low + Climate, Agro & Ice Stories..Nov 21st

After an evening that included not just rain & gusty winds, but small hail, thunder & lightning and downpours...more stormy weather in the forecast! A low pressure system is sliding up Washington into BC today. It will bring with it enough energy for showers and this possibility for thunderstorms again this afternoon along with gusty winds for the south coast.

- Snow levels are rather low today as well...the same system will generate heavy snowfall over Highway 3 - Paulson Summit to Kootenay Pass.  Up to 20 cm of new snow is possible with this low and lightning strikes also not out of the question
- The showers should end later this evening as a brief high pressure system builds in for tonight and most of Thursday. Still a risk of a brief shower but a much drier Thu than of late
- Thursday night however a pretty impressive Pacific low will roll on in..we will see the warm front first Thursday night and then the cold front Friday. Still working on winds and rain amounts but for some coastal sections we could be talking hurricane force winds
- Wind & snow warnings are already in place for central and coastal sections for tomorrow afternoon
- Drier weekend on tap..and cooler weather for early next week

Very Messy Prairie Weather
- A low pressure system is developing in Montana and will spread snow into Southern Alberta this afternoon. This band will set up and intensify along a line from Banff to Medicine Hat. 10 to 15 centimetres of snow can be expected by Thursday morning.
- The heavy snow & freezing rain will then track into southern SK this afternoon and evening. As of late this morning a large area of freezing rain has set-up over Southern Saskatchewan...along and south of the Trans-Canada Highway. Significant ice accumulation is possible today making driving conditions extremely treacherous. Saskatchewan Highways is reporting travel not recommended on many highways in Southwest Saskatchewan, and these poor driving conditions are expected to spread eastward throughout the day. The freezing rain will gradually taper off from west to east later this afternoon.
- In addition fog may create near zero visibility and then in case that wasn't enough a second weather system will bring some 10 to 15 cm of fluffy snow to the Kindersley region tonight.

UN report: World is moving away from realizing climate change goals
- a report by the UN Environment Programme released today says we are moving further away from the goal of limiting the rise in global average temperatures to below 2 degrees Celsius, as the concentration of warming gases in the atmosphere is actually rising
- Greenhouse gas emissions levels are currently around 14 per cent above the target levels for 2020. Instead of declining, concentration of warming gases, like CO2  have actually increased by around 20 per cent since 2000.
