(WGHP) – It may seem as though it has rained a lot throughout the month of September, however, it’s really only been through the second half of the month.
Out of the 23 days in September so far, nine of 23 days have observed a trace or more of rainfall. That’s 40% of the month.
We’re actually behind the normal rainfall amount through Sept. 23. Our September rainfall total is 3.00 inches compared to the month-to-date normal which is 3.57”.
Despite observing below-normal rainfall through Sept. 23, the last week of the month looks very active with rain in the forecast each day.
The Weather Prediction Center is forecasting between three inches and seven inches of rainfall over the next seven days in the Piedmont Triad. This amount of rainfall could easily take us from below normal to well above normal before September ends.
Why is there a chance of rain every day in the next week?
Well, part of it has to do with the tropics. Helene is forecast to make landfall on Thursday as a major hurricane near the Big Bend region of Florida.
After landfall, Helene is expected to track inland and will likely bring a significant amount of rainfall to North Carolina, especially the western half of the state.
But Helene isn’t the only low-pressure system that’s forecast to bring us rainfall. There’s another low-pressure system in the central part of the country associated with a cold front that will impact rainfall in the Tar Heel State.
The frontal system is helping fuel moisture and instability in the southeastern United States both of which are ingredients for creating rainy and stormy weather.
The combination of the two systems means plenty of moisture and instability for rounds of rainfall throughout the week.

It’s officially Autumn, which means we’re transitioning between the warm season and the cold season.
When we go from one “extreme” to another, like with temperatures, the atmosphere has to balance itself out. It does this by creating weather.
We typically see more rain in the transition seasons, fall and spring, because of this clash between warm air and cold air.
