(Today through Friday)

-A few isolated showers and thunderstorms possible across portions of Central Georgia and NE Georgia mtns this afternoon.

-Continued warming temperatures through Friday

A passing shortwave trough has resulted in continued mid to high level cloud cover across the forecast area. A weak surface low is also moving through the area and may result in variable winds through the morning. Increased boundary layer winds should inhibit any lower clouds this morning. Overall conditions will be fairly similar to yesterday -- with daytime cu and largely dry conditions (for most locales). Hi-res guidance does continue to hint at isolated showers and storms this afternoon likely due to slightly increased moisture and lift from the shortwave. Additionally, some terrain induced activity will be possible across far NE Georgia as well. Once the shortwave has passed gradual clearing is expected across the forecast area.

Toasty temperatures can be expected both today and on Friday. Today high temperatures will range from the low 80s across NE Georgia to mid 90s across much of Central Georgia. By Friday, most locations (aside from the NE Georgia mtns) will climb into the mid to upper 90s. The saving grace right now looks to be dewpoints -- which would largely keep heat indices below 100. Even still -- it's going to be hot so make sure to take necessary precautions if outdoors and check in on vulnerable groups!


(Friday night through Wednesday)
Issued at 326 AM EDT Thu Jun 13 2024

Taking a look at conditions starting on Saturday, High pressure and an associated ridge over the Great Lakes and Great Planes will mean temperatures will be HOT this weekend. Models are attempting to resolve low pressure in lee of the Appalachians and over North GA.
This is likely a product of NE flow around developing sfc lows in the Western Atlantic (see NHC outlook) pulling dry air into a wedge- like pattern for our area. PWATs will be slightly below normal, hanging around the 1.25" mark. Less moisture in the air will mean that temperatures climb above normal for this time of the year. The record high at the ATL airport on Saturday is 96, with recent forecasts consistently progging near 99. Temperatures elsewhere across the region will reach into the upper 90s to near 100, especially in east central GA. We aren't likely to cool off much into Sunday, with highs remaining in the upper 90s for much of the region. Moisture begins to surge as we get into early next week with PWATs climbing back over 1.5". When combined with a week mid level disturbance, PoPs return Sunday through Tuesday morning.
Temperatures will be in the upper 80s to low 90s by mid next week.


(12Z TAFS)
Issued at 635 AM EDT Thu Jun 13 2024

VFR conditions will persist through the period. FEW to BKN 060-080 cloud cover still present over the forecast area this morning.
Some lower cigs 040-050 starting to creep up near CSG. SCT to BKN Cu will be possible through the afternoon with clearing conditions after 00z with the departure of a mid-level disturbance. Winds remain on the east side though may waffle between SE/NE at times this afternoon though speeds remain light <7kts. Isolated shra/tsra possible after 18z but chances remain too low to include in any TAF at this time.

High confidence on all elements.
