.DISCUSSION... (Today through Thursday) Issued at 1201 AM CDT FRI JUN 19 2026
Regional radar shows the remnant low of Arthur centered just north of Atlanta. To our north, surface obs indicate an approaching cold front is extending southwest from a low over Quebec through the Appalachians and into the Ozarks. We've been spared from much of the higher rainfall totals and severe weather yesterday evening, and the primary zone of forcing is now pushing off to our east, but significant moisture content remains in place across the region. Other than an occasional shower or storm in the Montgomery area, a general decrease in activity is expected for Central AL through the predawn hours. As the frontal boundary begins to move into the area this morning, this feature will serve as the primary lifting mechanism to support additional showers and storms today. Coverage is likely to be highest across the southern half of the forecast area, and there are low chances for a few stronger storms to produce damaging wind gusts this afternoon. Soils remain very saturated, and the Flood Watch will remain in effect for most of the area through at least the end of the day as heavier downpours may easily result in areal or flash flooding, especially in urban areas. The frontal boundary is forecast to remain stalled along the Gulf Coast region this weekend, so rain chances have trended upward, and the Flood Watch may need to be extended through at least Saturday with an additional 1 to 3 inches of rainfall in the forecast for areas generally along and south of I-20.
A west to northwest flow pattern sets up next week, with elongated ridging over Mexico and the Four Corners, while a series of longwave troughs rotate across the Upper Plains and Great Lakes regions. Consequently, rain chances continue through at least the middle of the week, particularly on Tuesday as another front moves into the area. The finer details remain uncertain at this time, but we will need to keep an eye on potential MCS activity as well given the synoptic orientation.

.AVIATION... (12Z TAFS) Issued at 704 AM CDT FRI JUN 19 2026
Additional SHRA and TSRA development has occurred near the southern terminals of MGM and AUO this morning, and have included mention of TSRA in the TAFs through at least the mid-morning hours today. PROB30 for TSRA remains at all sites through this evening. Otherwise, IFR to LIFR ceilings will prevail across remaining terminals through much of the morning, with ceilings slowly rising through 18z. Most terminals should observe VFR ceilings by this afternoon, with winds remaining light or variable through the day. Ceilings are forecast to lower toward IFR category once again overnight tonight.

.FIRE WEATHER...
Increased rain chances continue as we will remain in a wet pattern through early next week. Ample moisture in place will keep MinRH values above 50% through the entire forecast period. Elevated fire weather concerns are not expected at this time.
