Mild temperatures and isolated showers for this evening
Temperatures will remain pleasant for the rest of the afternoon and into the evening with overnight lows above normal for this time of year in the low 50s. There will be a few isolated, light showers this evening (30%). Most will remain dry, but if you have Sunday night plans, you might want to grab your raincoat just in case.
More widespread showers will then arrive on Monday morning from about 8AM-12PM EDT, moving from west to east with peak timing for Chattanooga from 9-11AM. Then, showers will become more scattered in the afternoon, but the chance for thunderstorms increases for the afternoon into the evening. The afternoon storms may be strong to severe, especially for Chattanooga and south where there is a "Marginal" Risk for severe weather. The biggest threats will be for gusty wind up to 40mph and hail. There is limited moisture with this system, so total rainfall should be about 0.25-0.5" with highs in the mid-60s.
Conditions will dry out again on Tuesday with only a 10% chance for a stray shower, mainly in North Georgia in the evening. Temperatures will be cooler with highs near 60 and a partly sunny sky. Wednesday and Thursday will both be pleasant with highs in the mid-60s and mostly sunny.
Clouds will increase again on Friday with highs around 70, and then mostly cloudy on Saturday with highs in the low 70s and a chance for scattered nighttime showers.
