DISCUSSION

(This afternoon through Wednesday) Issued at 253 PM CDT THU APR 30 2026

This afternoon a frontal boundary extended from SC SWWD across SE GA and back toward the AL, MS, LA, and SE TX Gulf Coasts. Except for a low chance of a few showers and thunderstorms scraping our SRN counties this afternoon, C AL will remain rain-free. In the upper levels, a strong low pressure is centered over Ontario with another weaker low just off of the Baja Peninsula and zonal flow into AL. Through the short term, the Ontario low will slowly nudge EWD into Quebec. As it does so, the upper low W of Baja will push EWD, open up, and weaken. At the same time, weak disturbances will move through the zonal flow into AL. This will result in low to medium chances for showers returning through tonight, with the best chances across the SRN half of AL. Shortwave induced activity is expected to increase across the SRN half of AL during the day on Fri with medium to high chances of the activity being widespread Fri night into Sat morning.

The shortwave will exit the area Sat afternoon with rain-free and pleasant spring conditions in its wake for Sat night through Tue. Temperatures will slowly warm for the first part of next week as our airmass moderates and the surface ridge weakens. Another storm system will approach late Tue into Wed with a low to medium chance of showers and thunderstorms toward the end of the extended forecast.
