.DISCUSSION... Issued at 1244 AM CDT Thu Sep 18 2025
Now through Tuesday...
A closed upper low over the East Coast opens, leaving a weakening upper trough centered along the East Coast into the weekend. This will keep the Southeast under dry northeasterly upper flow into the weekend. A weak surface boundary moves south over the Southeast THursday into Thursday night, but with a dry airmass over the region, any rain chances are expected to be north of the forecast area. Shortwave energy moving east of the Mississippi River digs an upper trough over the river through the weekend, with the trough shifting east to over the Eastern Conus. A surface ridge develops over the Appalachians, then builds southwest through the rest of the week into the weekend, bringing east to southeast low level flow to the Southeast, and Gulf and Atlantic moisture inland over the region. The forecast area will see an increasing chance of showers and thunderstorms in the coming week with the increase in moisture and the approaching upper trough.
A weak ridge building over the Southeast the rest of the week will bring high temperatures rising to well above seasonal norms through the forecast, with around 90s expected over most of the forecast area Wednesday, then rising to the low to mid 90s by Saturday. The advancing upper trough will drop high temperatures back into the upper 80s to around 90 by Monday. More seasonal low temperatures in the mod 60s to near 70 Wednesday night to the upper 60s to low 70s for the rest of the forecast.
Weak, diurnally driven flow and decreasing tidal cycle will keep the risk of Rip Currents Low through the weekend into the coming week. /16
