As summer comes to an end, this time of year usually means we can experience major shifts in our weather patterns.
The October monthly outlook from the Climate Prediction Center has been issued, and it shows that over the next 30 days temperatures will be either near or slightly above average through the month. That doesn't mean that we won't see some fluctuations, though. Temperatures will occasionally cool down, but the overall temperature trend is expected to be warmer than normal. Our average high in October is the mid 60s with lows in the mid 40s.
Precipitation chances also seem to be much lower next month. The bulls eye for drier-than-normal conditions is setting up over the heartland and the Midwest.
October is typically not one of our wettest months. If anything, it's one of the months that we see the least amount of precipitation since average rainfall is little more than two inches.
About our change of season on Friday, the National Weather Service has a good explanation about the switch from summer to fall and the equinox.
There are only two times of the year when the Earth's axis is tilted neither toward nor away from the sun, resulting in a "nearly" equal amount of daylight and darkness at all latitudes. These events are referred to as Equinoxes.
The word equinox is derived from two Latin words - aequus(equal) and nox (night).
At the equator, the sun is directly overhead at noon on these two equinoxes. The "nearly" equal hours of day and night is due to refraction of sunlight or a bending of the light's rays that causes the sun to appear above the horizon.
