Finally, it looks like we will get a little relief from the heat and the humidity.
A cold front is passing through the KFVS viewing area this evening. At 9pm, the front was halfway through the area. The front should be through by morning. You will notice the front has passed as winds will shift around to the northwest/north.
The front is going to allow for some drier air to filter in from the north on the surface winds. This will help drop dew points in to the upper 50's and 60's.
The dew point is a key number to look at. It is a measure of the moisture in the air. With dew points under 60 degrees it feels rather comfortable. If the dew point goes over 60 degrees it starts to feel uncomfortable.
Over the last two weeks we have had dew points in the upper 60's and even lower 70's. That is air typically we have in place by late July and early August.
Be sure to enjoy the drier air. Winds will begin to shift back around to the south by Monday and that will bring moisture back to the area. This means the humidity will go back up, as well the temperatures.
Another interesting note about the cold front... I'm forecasting a high temperature around 84 degrees for Cape Girardeau. If we hit 84, this will likely be the first time in 16 days that we have been at or below normal. I for one wouldn't mind some below normal temperatures.
