(Today through Sunday) Issued at 312 AM CDT SAT APR 20 2024 A frontal boundary has stalled out near the I-20 corridor as the surface lows continue to slide east through the Mid-Atlantic and Great Lakes. As we move through the day the front will begin to slide to the south again as a kicker system begins to work into the area. Scattered showers and a few storms will be possible, especially this afternoon. The highest potential for storms will be in the southeast, where differential heating will help add some fuel to the airmass. Much lake the past several days strong storms with gusty winds and hail are possible but should remain isolated and limited. By tonight the front should be south of the I-85 corridor and north of I-10 in southern Alabama/Florida panhandle. Meanwhile a disturbance and low pressure system will ride along and north of the front tonight into Sunday. This will provide a fairly widespread soaking rain to the area through Sunday morning. Lightning will generally be limited to the far south through Sunday. By Sunday afternoon the majority of the rain will be south of the I-20 and continue to slide south and east. 16

(Sunday night through Friday) Issued at 312 AM CDT SAT APR 20 2024 Rain should be completely out of the forecast area Sunday evening as a shortwave trough swings across the region. As high pressure moves in, cool northerly flow will result in temperatures falling into the lower to mid 40s for lows on Monday morning and again on Tuesday morning. West-northwest flow at 500 mb and dry conditions will be the story through Friday along with a significant warming trend associated with westerly low-level flow. 87/Grantham
