Decided to make a new background set. This one includes many images from GOES's satellites.

My the time data on my barometer is correct. I even checked some other personal weather stations in the area and they showed the same thing; a sharp increase in barometric pressure. This definitely not a problem with my barometer. I'm still curious to find out what caused it. My best guess would be a downdraft from rain cooled air, as the cooler air comes down from the cloud above, it creates more pressure on the air below and the air is colder and more dense, those two reasons could have lead to the increase in the pressure.Could someone please explain this, someone who knows a good amount of meteorology. Now, we just had pretty decent thunderstorm, not much thunder or lightning, it was mostly a heavy rain shower; it turned it a to be beautiful when it became a sun shower with double rainbows. Anyway, could someone tell me why did the barometric pressure increase during the shower, and then decreased after it ended. Normally, I would think it should decrease because of an updraft. Could a downdraft cause this? Here's the data from the shower:
Are you sure the time data on the barometer was correct? That definitely should be lower during the thunderstorm, primarily in the beginning to middle (if MY barometer is correct, it goes down at the beginning/before).
Well, it can mean many things. Hopefully they turn out good.57.8°F Thunderstorm
EDIT: Beautiful Sun-shower right now. Perfect spring day
AMAZING DOUBLE RAINBOW!!!
All the way? Have you figured out what it means?
