Day 4-8 Outlook
Day 4-8 Convective Outlook NWS Storm Prediction Center Norman OK 0349 AM CDT Tue May 14 2024 Valid 171200Z - 221200Z ...DISCUSSION... A shortwave trough is forecast to move across the southern Plains and into the Lower MS Valley on D4/Friday. Strong mid-level flow will precede this shortwave, spreading eastward from the Lower MS Valley across the Southeast. Airmass across the Lower MS Valley will likely be characterized by dewpoints in the low/mid 70s, with strong instability developing ahead of the approaching shortwave. Severe thunderstorm development is anticipated as the shortwave and associated surface low interact with this unstable and strongly sheared airmass. The timing of thunderstorm development and favored convective mode remains uncertain, but the overall environment and potential severe merits introducing a small 15% area from central LA into central/southern MS. The severe potential may extend into D5/Saturday across AL, GA, and FL Panhandle/northern FL as the shortwave trough continues eastward. However, uncertainty regarding convective evolution from D4/Friday as well as a less favorable severe environment precludes introduce any outlook areas. Shortwave ridging will likely progress through the central/southern Plains on D6/Sunday and the MS Valley on D7/Monday. Medium-range guidance has been consistently suggesting a shortwave trough will progress through the Southwest and into the central/southern Plains early next week. Several days of moisture return could precede this shortwave, with some severe potential becoming more apparent early next week. Even so, given the forecast range and variability within the guidance (particularly with timing), predictability remains low. Read more

SPC 0730Z Day 3 Outlook
Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0229 AM CDT Tue May 14 2024 Valid 161200Z - 171200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS CENTRAL AND NORTH TEXAS... ...SUMMARY... Strong to severe thunderstorms are possible across north and central Texas on Thursday. Isolated severe thunderstorms are also possible across portions of the Mid Mississippi Valley. ...Southern Plains into the Lower MS Valley... A southern-stream shortwave trough is forecast to progress eastward across the Southwest/northern Mexico and through the southern Plains on Thursday. Strong mid-level flow will likely exist throughout the base of this trough, spreading eastward across TX and into the Lower MS Valley ahead of the wave. Favorable low-level moisture (i.e. dewpoints in the upper 60s/low 70s) is expected to advect northward across TX throughout the day. Given this low-level moisture, strong buoyancy is expected to develop across areas that experience ample daytime heating. This currently looks most likely from the Low Rolling Plains/Big Country TX into Hill Country/central TX, with more uncertainty farther north (from the eastern TX Panhandle into western/central OK) due to influence of Wednesday night's thunderstorms. Late afternoon thunderstorm development is anticipated, with the combination of airmass destabilization, increasing large-scale ascent, and low-level convergence supporting initiation. Strong buoyancy and shear will support an initial supercell mode and robust updrafts capable of large to very large hail. Quick upscale growth appears probable, with the resulting convective line pushing southeastward across central and southeast TX. Elevated thunderstorms may precede this convective line from east/southeast TX into southern LA, and a few of these storms may acquire updrafts strong enough to produce hail. ...Mid MS Valley... Showers and thunderstorms will likely be ongoing over the region early Thursday morning before continuing northeastward and weakening. Heating in the wake of this early morning activity is expected to result in limited convective inhibition and moderate buoyancy by the afternoon. Convergence along a weak cold front and associated frontal low may result in thunderstorm development. An outflow boundary from the morning storms may also exist, providing another area for low-level convergence and storm initiation. Moderate westerly flow aloft could support a few stronger storms capable of large hail, damaging gusts ..Mosier.. 05/14/2024 Read more

Strong buoyancy and shear will support an initial supercell mode and robust updrafts capable of large to very large hail. Quick upscale growth appears probable, with the resulting convective line pushing southeastward across central and southeast TX. Elevated thunderstorms may precede this convective line from east/southeast TX into southern LA, and a few of these storms may acquire updrafts strong enough to produce hail. ...Mid MS Valley... Showers and thunderstorms will likely be ongoing over the region early Thursday morning before continuing northeastward and weakening. Heating in the wake of this early morning activity is expected to result in limited convective inhibition and moderate buoyancy by the afternoon. Convergence along a weak cold front and associated frontal low may result in thunderstorm development. An outflow boundary from the morning storms may also exist, providing another area for low-level convergence and storm initiation. Moderate westerly flow aloft could support a few stronger storms capable of large hail, damaging gusts ..Mosier.. 05/14/2024 Read more
