Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1258 AM CDT Thu Apr 03 2025 Valid 041200Z - 051200Z ...THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS FROM NORTHEAST TEXAS ACROSS MUCH OF ARKANSAS AND INTO FAR SOUTHERN MISSOURI... ...SUMMARY... Several clusters of strong to severe storms are possible from central Texas across the ArkLaTex and into the lower Ohio Valley Friday and Friday night. The greatest threat for tornadoes, large hail and damaging winds will be from the ArkLaTex across much of Arkansas into far southern Missouri, including strong tornado potential. ...Synopsis... On Friday, a broad fetch of south/southwest winds aloft will extend from the southern Plains into the Midwest, as an upper low moves across AZ/NM. A surface boundary will extend roughly from the OH Valley into central TX early on Friday, with a wave of low pressure developing during the day over northeast TX/southeast OK. This feature will then translate northeastward along the front into IN/OH late. As this occurs, a rather rapid warm frontal surge will occur over AR and into far southern MO, aided by persistent southerly deep-layer winds from surface to 850 mb. This will also result in a rapid increase in instability, and shear favorable for supercells with tornado potential. Behind the low, a cold front will push across the remainder of northern TX and into south-central TX. Although post frontal, elevated instability will persist, with the influence of the upper trough to the west resulting in overnight hail potential into central TX. ...From Texas into Arkansas and toward the lower Ohio Valley... Scattered showers and storms are likely near the front from the Red River into northern AR/southern MO early in the day. Sufficient instability and lapse rates, along with strong deep-layer shear will favor hail potential. During the day, areas of heating will occur over the warm sector, which will remain very moist. Afternoon supercells are anticipated over northeast TX/southeast OK into western AR, with a continuation across northern AR/southern MO through evening. This area will experience substantial pressure falls with a favorable corridor for a strong tornado threat. Depicted model hodographs indicate effective SRH over 400 m2/s2 will be common. Given continued northward motion of the warm front across southeast MO into the OH Valley late, storms should be able to persist/ride along with the front with access to unstable air mass. Overnight, cool temperatures aloft with the upper trough and a surge of elevated theta-e from the southeast and atop the surface cold front should favor widespread storms with large hail expected into central TX. ..Jewell.. 04/03/2025 Read more
