DISCUSSION

(This afternoon through Thursday) Issued at 227 PM CDT FRI MAY 1 2026

This afternoon a stationary boundary is situated along the Gulf Coast. A second reinforcing cold front is present to our N. In the upper levels, a strong low pressure is centered over the boundary of Ontario and Quebec with a shortwave over the desert SW and zonal flow into AL. Through the short term, the Canadian low will continue further into Quebec. As it does so, the upper shortwave will weaken over the WRN US as yet a 3rd low digs across the Pacific US Coast. At the same time, weak perturbations from the shortwave will push EWD through the zonal flow across AL. This will result in medium to high chances of showery activity spreading across C AL, being widespread at times, now through Sat morning until the wave moves out.

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 and associated cold front will approach the Deep South late Tue. A low to medium chance of showers and thunderstorms will be present for the middle of next week along and ahead of the front.

Ahead of the trough, there will be high confidence in rain showers affecting the forecast area this evening and overnight. High confidence in ceilings decreasing to MVFR criteria through the evening areawide with lower confidence in IFR conditions being reached during the pre-dawn hours Saturday morning with MGM and AUB having the highest chance for these conditions. Medium confidence in improving flying conditions by late morning and into the early afternoon as cloud bases rise and cloud thickness gradually decreases through the afternoon.

AMD NOT SKED will continue for TCL due to intermittent observations.
