10/8 – Rob Knight’s “Pleasant” Friday Morning Forecast

The persistent mid/upper low-pressure over the mid-Mississippi Valley will finally lift northeast to the Great Lakes region through tonight. This will be replaced by an upper level high-pressure building in from the southern plains into the Gulf Coast region. Surface high pressure will remain over the local area through the period while gradually becoming centered east of the area by Sunday. This will keep dry weather and lower humidity over the forecast area, although humidity levels/dew-points will be coming up slightly on Sunday to more muggy readings. Diurnal temperatures ranges will be fairly high meaning very warm/above normal for daytime highs, but comfortably cool/a bit closer to seasonal normal for the lows.

The next weather maker will be a potent and progressive disturbance will move across the southern Plains Sunday night/early Monday into the mid to lower Mississippi Valley on Monday. The system is only expected to bring a slight chance of afternoon showers on Monday over western portions of the area. Another potent disturbance will kick out of the Rockies into the Plains region mid-week. There is no strong signal for the southern end of this system to have much punch into the forecast area. Temperatures are not likely to vary much without having high rain chances of a frontal passage through the period. This means temperatures well above the seasonal averages for mid-October with higher humidity levels keeping the diurnal ranges lower than the short term.
