    Larry Cosgrove shared a post: What a "Greenland block" means to you. See also: https://lnkd.in/gDgAvsT The weather pattern over North America during the next 5-6 weeks will likely be heavily influenced by a large blocking signature, a positive 500MB height anomaly commonly known as a Greenland Block. A symptom of a negative North Atlantic Oscillation, the persistent closed ridge complex can produce two noteworthy effects: 1) Keeping the incoming storm track suppressed toward lower latitudes in the USA, with strongest periods of disturbed weather off of the shoreline of the Mid-Atlantic and New England states and 2) enabling drainage of cold air from Canada into the lower 48 states. All of the numerical models have consistently shown ridging in the vicinity of Baffin Island/Greenland from the medium range (and in some cases) through the month of January. The analogs are also strongly favorable for this feature. If you look at forecast guidance, you see a trend of storms coming into the West Coast being diverted into Texas, then to Georgia, then slowing up along and off of the East Coast. It is a fairly classic scenario. The result? Heavier than normal precipitation in the eastern half of the U.S. Temperatures gradually trending below average after each storm.

    I use a floodlight that is installed just beneath the peak of our roof.  House faces due North/South, along with slope of roof, so my east facing bedroom window is underneath the light.  Also I have a nice outdoor light at ground level beside a sliding glass door that works well.  As long as the light is bright and close by, but not within direct view, you're good.

    Why are my imgur posts not embedding, I swear they used to?  I don't have anymore on-site storage.  

    My Ring floodlight cameras provide me 360° views around my entire home...

    This one (facing NE) early Thursday am near the end of our recent snowstorm!

    Sorry 11" would be a debacle, 52 more years I ain't got. My bar is set at 16" with a range of 14-18"

     

     

    Funny how our “snow” minds work...

    Just imagine for one moment that all models, up until this run of the Euro, had us getting 1-3”....

    Then we get this run of the Euro dishing out ~12” immediately NW of Philly...

    Different reactions/emotions no doubt...

    Expectations!!!

    Ditto...

    As I mentioned previously, I’ve had one for about a month now and love it!!! The rain is a bit high so far but they have a system where it adjusts about 24 hours later and with its AI it calibrates so within a couple of months apparently becomes increasingly accurate and will deliver forecasts specific to your back yard.

    Amazingly cool system and they’re doing some type of BOGO now!

    I’m waiting til the off the grid version is released to buy another one for my Maine home!
