I plan some of my activities around when it will, and won't, be raining.
A useful website, and you can access it with their App, is Weather Underground (WU). Which, until recently, was owned by IBM, so they should have had access to really cool computers and technology.
Besides weather forecasts, they also have timely reporting of air quality that lately has been on the unhealthy side, worsened by the fog that frequents this time of the year. At least when it's raining, all the unspecified “particulate matter” washes to the earth (yes, where it gets into our food and groundwater) and we're not breathing it in.
One cannot plan far in advance with WU's predictions. The better practice is to check often as the time for something you want to do without rain approaches.
On Saturday night, I checked the forecast for Sunday. At first, there was to be a little rain at 7 pm, later changed to 8 pm, on Sunday. Starting Tuesday, steady rains were predicted for a couple of days.
When I got up this morning, and checked around 9 am, all that had changed: Rain all day Sunday, with a one-hour break at 7 pm. Rain Sunday night through much of the week. That was later modified to rain Sunday evening and continuing through Monday and Tuesday, with a break on Wednesday and Thursday.
So the weather cannot be reliably forecast even a day in advance. Yet we are told that there are solid scientific “models” that accurately tell us what the weather will be like years and decades from now.
Once again, truth is hidden in plain sight. A reminder that more simply need to use their brains, their instincts, their intuition, ask questions, pay attention.
Astute comments Terry ... thank you. Found this app today which is interesting
