(this afternoon through friday) issued at 214 PM EDT thu sep 17 2026
North and central georgia will continue to experience hot and dry conditions associated with an unseasonable upper level ridge centered over the arklatex region through thursday night. Outside of a few isolated showers or thunderstorms over our most northeastern counties, most locations will remain precipitation free today. As this ridge shifts to the west, the bulk of drier air aloft will also retreat and allow for lee-side troughing along the appalachians. This will provide enough instability to aid in the development of some diurnal shower and thunderstorm activity on friday, propagating out of the northeast from the carolinas into our area by the afternoon. Some of these storms could be strong to isolated severe with damaging wind gusts the primarily threat, as they interact with residual mid-level drier air and available CAPE, particularly over the northeastern portions of our cwa. As such, the SPC has placed our northern and eastern counties under a marginal risk for severe weather, which aligns with ml medium range products indicating a similar risk. Otherwise, storm coverage is not expected to be widespread on friday.
High temperatures will continue to be unseasonably warm, running 5- 10f above normal across the area today and slightly higher for friday. Temperatures will range from the upper 80S to low 90S today and increase a couple of degrees areawide on friday. Surface winds will favor the east to northeast around 5-10MPH with a few gusts up to 20 MPH, particularly over southern zones through the day before becoming light and variable overnight. As the effects of the 'wedge' break down, winds will become more variable on friday.

The ridge is finally expected to break down sunday into monday as a front approaches. Isolated thunderstorms will be possible on sunday afternoon, becoming more widespread on monday but total rainfall is expected to be less than an inch for much of the cwa through the forecast period.
The front will bring afternoon thunderstorms back into the forecast to start off next week. This will help to moderate temps down to the upper 80S and low 90S. There are some signs that temps will drop into the low 80S towards the end of next week as more dry air clears out afternoon convection chances.

High pressure conditions will support prevailing VFR conditions through the period. Patchy MVFR-IFR conditions are possible over the northeast georgia mountains after 07Z. Surface winds will favor the east to southeast around 4-8KTS with occasional gusts up to 18KTS over southern zones and will become light and variable after sunset. An isolated shower or thunderstorm is possible over the far northeast counties this afternoon, otherwise precipitation chances are limited through the period.
