Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 355 PM EDT Tue May 28 2019 Valid 00Z Wed May 29 2019 - 00Z Fri May 31 2019 ...Heat wave to continue in the Southeast... ...Strong storms and excessive rains possible from the Plains to the northern Mid-Atlantic region... ...Additional heavy rains likely across the Arkansas Basin on Wednesday... Dry conditions with well-above normal to record-breaking temperatures are expected to continue across the Southeast and southern Mid-Atlantic region through midweek. Across much of the region, daytime temperatures are expected to reach into the upper 90s and low 100s each day through Thursday. To the north, a slow-moving frontal boundary extending from the Northeast and northern Mid-Atlantic region back into an area of low pressure moving across the central Great Plains will provide a focus for showers and thunderstorms. Some of these storms may become strong to severe. The Storm Prediction Center is highlighting the potential for severe storms, capable of producing large hail, damaging wind and tornadoes Tuesday afternoon into tonight from the central Plains eastward into the Midwest. Severe storms are also expected from portions of the upper Ohio valley into the Northeast Tuesday afternoon and evening. Heavy rain is also a threat, which could exacerbate the already very wet soil conditions across some areas. The Weather Prediction Center has highlighted portions of the lower Missouri and mid Mississippi valleys with a Moderate Risk for excessive rainfall for Tuesday afternoon through the overnight. Heavy rains with very wet antecedent soil conditions will likely lead to rapid surface runoff and stream rises across this region. On Wednesday, storms will continue to develop along a stationary boundary extending from the northern Mid-Atlantic region back into a weak area of low pressure moving into the mid Mississippi valley. Once again, these storms may become strong to severe and produce heavy rainfall amounts, producing flash flooding concerns. Meanwhile, storms are expected to become more numerous along a trailing cold front extending back into northern Texas. Here also, severe thunderstorms and flash flooding will become a concern. The Storm Prediction Center is highlighting portions of the southern Plains and Ozark region with an Enhanced Risk for severe weather on Wednesday. The Weather Prediction Center is highlighting this area with a Moderate Risk for Excessive Rainfall as well. Any additional heavy rains across this area will likely prolong historic flooding already occurring along portions of the Arkansas River.
