Looks like the GFS op is the outlier on those charts. Neutral/positive NAO and more +AO.
It's March and 55F at almost 10pm with little snow left. We'll be through mud season in a couple weeks at this rate.
I read something the other day that the virus was found still alive in a vent in one of the Asian hospitals. So it can apparently survive being airborne for awhile as well.
Everything I've read has been contrary to this. The flu has an R0 of 1.3 and COVID-19 has been between 2-3. So people are spreading it to twice as many people as they would the flu. The flu has no efforts taken to reduce the viral spread either.
Despite what they say, I think proper masks do mitigate the risks. However, if droplets stick to the outside of your mask you need to wash your hands immediately and sanitize anything you touched between removal and hand washing.
