DISCUSSION
Issued at 153 AM EST Tue Feb 10 2026
A mild SW low level flow will develop today as a low pressure system crosses the Great Lakes, and a high pressure system is located near FL. Channeling of the SW winds up the TN Valley could create some gusty conditions this afternoon. The stronger warm advection today will bring high temps well above normal, mainly in the 60s with some low 70s around Chattanooga. The approach of a cold front will bring increasing cloud through the day, with a chance of rain arriving around midnight. Forcing isn't strong with the nearly zonal mid/upper flow, and is mostly associated with isentropic lift through the low levels. Thus, QPF will likely be light, around a tenth to a quarter inch in most spots.
Temperatures will be cooler behind the front, but not dramatically so as the midlevel pattern remains fairly flat and nearly zonal. Mostly dry weather will continue through Friday, then the next chance of rain arrives on Saturday a a southern stream shortwave trough traverses the southern Conus. This could be a fairly dynamic system with a strong southerly flow ahead of it, suggesting a potential for mountain waves in the Saturday night time frame. If the system develops as a closed low as depicted by the GFS, rain chance will linger into Sunday.
Dry and mild conditions return for early next week.
