Northwest Georgia residents can expect a mostly dry weekend with increasingly hot temperatures, according to the latest weather forecast. Patchy fog is expected this morning but should dissipate by 10 AM, otherwise, mostly sunny, with a high near 88 and calm winds.  Tonight, mostly clear with a low of 66.  The chance of rain remains minimal through Saturday, with only isolated instances possible in the far southern and southeastern regions. This shift to drier conditions comes after the passage of a weak cold front, bringing marginally drier air into the northern half of the area. An upper ridge currently positioned to the west is forecast to expand eastward and build overhead by Saturday, further contributing to the dry weather and rising temperatures. By Saturday, temperatures will climb further, reaching the low to mid-90s across the region. While heat index values will be slightly higher than the air temperature, they are not expected to reach Heat Advisory levels this weekend. However, residents should prepare for the warmest temperatures of the year so far next week.
