Subj : DAY2SVR: Nws Storm Prediction Center Norman Ok To : wx-storm@lists.illinois.edu From : COD Weather Processor Date : Wed Nov 08 2023 17:17:28 ACUS02 KWNS 081717 SWODY2 SPC AC 081715 Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1115 AM CST Wed Nov 08 2023 Valid 091200Z - 101200Z ....NO SEVERE THUNDERSTORM AREAS FORECAST... ....SUMMARY... Isolated thunderstorms are possible from central/southern Arkansas and northern Louisiana into southern/eastern Texas on Thursday. ....Synopsis... On Thursday, an upper low will deepen as it moves from near Lake Superior into southern Quebec, with intensifying mid and high level winds across the Northeast. Behind this feature, modest southwest flow aloft will extend into the southern Plains and northern Mexico, with subtle embedded disturbances. At the surface, the primary feature of interest will be an elongated cold front which will interact with mid to upper 60s F dewpoints from the lower MS Valley into central and eastern TX. This front will push toward the TX Coast by Friday morning, with a small warm sector remaining from near Houston eastward along the northern Gulf coast at 12Z Friday. ....Southern and eastern TX into southwest AR... MUCAPE on the order of 500 J/kg should develop both north of the front in an elevated sense and ahead of it into southern TX where dewpoints will be higher. Weak warm advection atop the boundary as well as increased differential divergence near the right entrance region of the intensifying upper jet should support scattered convection centered over the Arklatex during the day. Temperatures aloft will not be particularly cool, suggesting only non-severe storms. To the south into TX and ahead of the cold front, heating will lead to surface-based parcels and isolated storms. Low-level winds will remain weak, and temperatures aloft relatively warm. As such, severe storms are not anticipated. Elsewhere, a strong cold front will approach the coastal Pacific Northwest late in the day, and minimal CAPE values could support isolated lightning flashes with shallow convection along the WA Coast after 03Z. ...Jewell.. 11/08/2023 $$ = = = To unsubscribe from WX-STORM and you already have a login, go to https://lists.illinois.edu and use the "Unsubscribe" link.
