| With surface High shifting offshore and upper level ridge weakening, expect more return flow component across north GA. Latest satellite imagery showing cirrus shield streaming in across central and south GA from upstream convective activity already beginning to fire in Miss. Both NAM/GFS lean towards a Thursday evening cold frontal passage. With daytime heating to aid convective parameters and potent short wave ejecting off main upper Low, could be another good round of severe weather on tap for late Thursday afternoon, as upper level jet max approaches lower Tenn Valley. Until then stable conditions with ESE to SE flow will prevail until Thursday AM, which should keep both ozone and particle pollution in green range across Metro Weds with good ventilation. BBM
