12/7 – Rob Knight’s “Cooler & Damp” Tuesday Morning Forecast
Forecast issue over the next few days will be the location of the current frontal boundary. I don’t expect much movement with the front now south of the area, at least today. A batch of energy will sweep eastward across the area this afternoon into early evening. There’s likely to be the occasional patch of light rain or drizzle, but any rainfall amounts today are expected to be rather light.
Little change in conditions overnight tonight, with again, a few patches of light rain showers or drizzle, and not much movement in temperatures. An upper level disturbance moving through the middle Mississippi River Valley may eventually push some of the moisture out of the area on Wednesday. Models show a warm-up Thursday and Friday with the mercury pushing the 80 degree mark. This will be conducive of t-storms activity closing out the workweek.
Then next system approaches Friday night and Saturday with a frontal boundary approaching our area Saturday afternoon. A prefrontal squall will bring the potential for low-end threat severe storms late Friday night or Saturday. Widespread showers and storms throughout the day on Saturday could bring a solid inch to locally higher amounts with this frontal boundary. Much cooler and drier conditions expected on Sunday and Monday as Pacific type airmass settles in with highs around 60 though the period.
