Isolated severe storms are possible this evening and overnight across the ArkLaTex and Ozarks. ...Ozarks/ArkLaTex... Height falls will regionally increase late today into tonight owing to the interface of a northern Plains shortwave trough and the east/northeastward ejection of a trough/jet streak from the central/southern Rockies. As this occurs, lower/some middle 60s F surface dewpoints are expected to become increasingly prevalent tonight across the ArkLaTex and sizable portions of Arkansas in advance of a front and dryline across Texas. Thunderstorms are expected to become more probable regionally and tend to increase in coverage after sunset, and particularly into the late evening/overnight hours as they move northeastward across the region. Initial development will be possible across far southeast Kansas, central /southern Missouri, and eastern Oklahoma/western Arkansas, with more isolated storms farther south. Regarding the northern end of development, surface-based buoyancy should remain limited in vicinity of the near-frontal surface wave across Missouri. While small hail and/or gusty winds may occur, the primary surface risk should be focused farther south. A few severe storms will be possible across the Arklatex/Arkansas this evening into the overnight. Hail is the most probable hazard amidst 40-45 kt effective shear, but forecast soundings suggest that a few near-surface-based storms could materialize this evening into the overnight. Accordingly, a low potential for a tornado may also exist mainly across portions of Arkansas. ..Guyer/Weinman.. 12/08/2023 Read more View the full article Quote Link to comment Share on other sites More sharing options...
