Sometimes, the seven-day forecast tells you everything you need to know about the next week. Other times, it tells you virtually nothing. This is one of those instances, where it tells you less than it should.
Between stalling cold fronts, pesky cloudcover, and sluggish warm fronts, the temperature could have great contrast between the Tennessee state line, and Highway 82 corridor between Wednesday and the weekend.
Wednesday, some pesky clouds could limit temperatures near the Tennessee State-Line to the upper 40s and low 50s, whereas temperatures South 82 could be in the upper 50s.
Thursday, a cold front moving through the area could trigger a few showers, and drop temperatures back into the 40s for highs.
Friday is the trickiest of the forecast. The front from Thursday is expected lift back northward as a warm front early in the day. Basically, that means our high temperature could occur early, perhaps before 9 AM or 10 AM for some spots. Where ever this front is, high temperature south of it will be in the 60s, whereas temperatures behind it will quickly drop through the 40s and 30s. Showers are also likely Friday (and possibly Thursday).
What is the likelihood that the situation will play out differently than I anticipate? 100%. Listen, any time warm air is trying to sneak in a brief window before another cold front, there's a likelihood of being wrong, not right :-). We'll keep refining the forecast.
