Weekend Washout

Today has been the epitome of a Fall day: morning lows right around 40 and highs expected to reach into the low 70s with clear skies and calm winds all day long. It literally could not be drawn up any better. However, like all good things, this too must come to an end. A low pressure system will be moving up from the Southern Great Plains and bring with it plenty of rain over the next few days.

Tomorrow, we’ll start off at 44 degrees with partly cloudy skies. More cloud cover will be moving in by the lunch hour as rain moves up from the south. Expect the rainy weather to begin during the afternoon to evening hours and persist throughout much of the night. Highs will be in the mid-60s with dense cloud cover during peak heating keeping us cooler than what we experienced today.

Saturday will see quite an increase in temps as warm air advects into the Tennessee and Ohio Valley regions. Morning lows will be in the 50s with afternoon highs in the low to mid 70s despite the overcast skies. Models differentiate on how much rain we’ll see, but thy are starting to agree that it will likely be an inch or more. The NAM depicts less than both the GFS and the ECMWF because it is predicting a break in the constant rainfall for about half the day on Saturday. If the ECMWF and GFS prove true, we’ll see constant moderate rainfall for all of Saturday with totals amounting to 2+ inches for SOKY. Winds will be whipping as the cold front moves East toward us: 20+ mph sustained winds and gusts upwards of 35mph won’t be out of the question.

Sunday will be dry all day with temps in the 50s for the morning and highs staying down in the 60s. After such a wet weekend, a nice, cool Sunday will be a welcomed sight.
