THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF THE EASTERN TEXAS PANHANDLE INTO WESTERN OKLAHOMA

### SUMMARY

Scattered severe thunderstorms are expected late this afternoon into tonight from northwest Texas and the Texas Panhandle into western Oklahoma and southern/central Kansas. Large to very large hail, a few tornadoes, and severe/damaging winds are possible.

20z Update

No changes have been made to the D1 Convective Outlook with this update.

Visible satellite continues to show continued mid-level cloud cover across the far eastern Texas Panhandle into central Oklahoma. A warm front has shifted northward across central Oklahoma, with 60F dew points as far north as a line from the Oklahoma City Metro to Tulsa and northeast OK. Dew points in the Texas Panhandle are also slowly increasing, with mid to upper 50s. Breaks in the clouds are increasing across this region, with filtered heating and temperatures warming into the mid 60s to 70s on the western edge of the cloud cover. Cu development is noted across the dryline in far western TX/eastern NM. Steady cumulus development is ongoing across the southern Texas Panhandle into western OK, with billow clouds downstream of Cap Rock from Motley, Childress, and Cottle Counties indicative of continued low-level stability, which is noted in the 18z sounding from AMA.

Thunderstorm development is expected near/just east of the Caprock Escarpment with a few more hours of additional daytime heating by late afternoon (4-6 PM CST as mentioned below). Initial development is expected to be supercelluar, with potential for large to very large hail. Strengthening of the low-level jet and resulting increase in low-level shear through the evening will enlarge hodographs, with an increasing risk for tornadoes, with potential of a strong tornado (EF2+).

Additional thunderstorm development may also occur across the length of the dryline into west Texas where a Marginal Risk was maintained. A Marginal Risk also continues across the Ohio Valley. See previous discussion below for more information.

Southern/Central Plains

An upper trough will amplify over the western U.S. today as a broad zone of modestly enhanced mid-level southwesterly flow persists over the southern/central Plains. At the surface, lee cyclogenesis is forecast to occur across eastern Colorado through this evening, which will promote continued northward transport of low-level moisture across Texas into Oklahoma/Kansas. A surface dryline will also extend southward from the low over the southern High Plains.

Multi-layer cloud cover remains semi-prevalent at late morning but peripheral gradual clearing is noted across parts of western North Texas as well as along the New Mexico/Texas border vicinity. The strongest heating/mixing will occur in vicinity across far west/northwest Texas, but it seems probable that storm development will occur within the somewhat richer moisture near/just east of the Caprock Escarpment including parts of Low Rolling Plains and Texas/southwest Oklahoma border vicinity. Such development should occur by around 4pm-6pm CST as convective temperatures are breached.

Somewhat modest/nebulous large-scale ascent will probably support a multi-hour period of semi-discrete supercells even if effective shear is not robust and low-level shear/SRH a bit modest during time of initial development, but nonetheless steadily strengthening toward/after 00z/6pm CST. This will include associated threats for large to very large hail initially, potentially up to 2-3 inches in diameter. The increasing low-level shear through the evening will also foster enlarged low-level hodographs and the potential for a few tornadoes with this activity, potentially including a spatiotemporal window for a strong (EF2+) tornado even if a more complex mode is evolving. Over time, convection is forecast to grow upscale into a small but potentially intense cluster as it moves northeastward into parts of western/northern Oklahoma and southern Kansas.

Isolated supercells may also occur along the length of the dryline across west Texas late this afternoon/evening, with associated threat for occasional large hail and severe wind gusts. However, confidence in any more than isolated coverage remains low due to weak large-scale forcing. Farther north, isolated severe hail may occur tonight with elevated convection in a low-level warm advection regime across eastern Nebraska, northwest Missouri into Iowa.

Ohio Valley to the central Appalachians

A mid-level shortwave trough will move quickly eastward today across the Ohio Valley. Modest low-level moisture will remain in place along/south of a front, with generally weak instability forecast across the warm sector. Even so, sufficiently strong low to mid-level winds associated with this shortwave trough may promote a few instances of damaging winds with loosely organized clusters that develop and spread eastward through the afternoon.

Florida Peninsula

Beneath an upper high and within an easterly low-level flow regime, strong heating will occur today across the Florida Peninsula, with dewpoints dropping into the mid 60s F. Despite the upper high, mid-level temperatures (-11 or -12C at 500mb) will remain relatively cool. Scattered convection appear probable along the western Florida Peninsula during the afternoon where low-level convergence will be maximized. Locally strong wind gusts will be possible, although organized severe thunderstorms are not expected.

THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS IN EASTERN KS/OK AND WESTERN MO/AR

### THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS SEPARATELY IN WEST TX

### SUMMARY

Scattered severe thunderstorms are expected from late afternoon Friday through Friday night from parts of the southern Great Plains to the Midwest. The greatest potential for a couple strong tornadoes and isolated very large hail is across eastern portions of Oklahoma/Kansas and western portions of Arkansas/Missouri.

Synopsis

Broad upper trough over the West should split into two distinct impulses by Friday night. The leading shortwave trough should eject from the Four Corners across the central Great Plains to the Upper Mississippi Valley, while a backside cutoff low evolves southward over the Lower CO Valley. Lead cyclone should track from the western KS vicinity across IA to the Upper Great Lakes. The dryline should mix towards central OK/TX through late afternoon. A surface cold front will accelerate southeastward across the central/southern Great Plains on the backside of the lead cyclone.

Central/southern Great Plains into the Midwest

Overall forecast has substantial uncertainties as latest guidance trends towards a more bimodal and less robust setup across the level 3-ENH risk vicinity. The most probable signal is for initial mid to late afternoon storm development to occur near the surface cyclone track in KS across the adjacent MO Valley. Strong deep-layer shear will support supercells near the immediate triple-point region and downstream warm conveyor, with primary risks of large hail and a couple tornadoes. But convection should grow upscale relatively quickly along the surface warm front, as well as the accelerating cold front. One elongated QLCS or a pair of QLCSs may evolve during the evening. The lead one should progress east-northeast towards the Lake MI vicinity with a threat for mainly damaging winds and a few embedded tornadoes, along the northern periphery of the surface-based instability plume. Farther south, the cold frontal QLCS should expand southwestward and progress more east-southeast. A mix of large hail, damaging winds, and perhaps a couple embedded tornadoes are plausible. But increasingly veered low-level winds near the front should taper the threat overnight.

A separate region of low-level warm conveyor storm development is evident downstream of the OK/TX dryline, mainly along a portion of the Red River towards the Ozarks during the late afternoon to early evening. Low-level and deep-layer shear profiles will be conditionally favorable for discrete supercells, amid a richly moist boundary layer and sufficiently steep mid-level lapse rates. With near-neutral mid-level height falls and peripheral influence of the mid-level jetlet farther to the west/northwest, confidence is below average on longer-lived/stronger supercells becoming sustained. Have shifted the level 3-ENH risk to be centered on this region, where storm development at least appears increasingly probable on Friday night.

West TX

Consensus of CAM guidance indicates an overnight corridor of storm development to the cool side of the accelerating cold front as it impinges on the western lobe of the TX buoyancy plume. Rather steep mid-level lapse rates and strong effective bulk shear could support a corridor of elevated large hail. The undercutting nature of the front suggests this corridor will remain spatially confined.

THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS FROM TX TO LOWER MS VALLEY AND THE UPPER OH VALLEY TO LOWER GREAT LAKES

### SUMMARY

Isolated to scattered severe thunderstorms are possible from Saturday morning into the evening across a broad swath of the southern Great Plains to the Lower Great Lakes. Isolated very large hail may occur in parts of Texas.

Synopsis

An upper trough consisting of multiple embedded shortwave impulses will move east from the Upper Midwest to the Great Lakes. A closed low over the Lower CO Valley will further retrograde to west of Baja CA. A surface cyclone over eastern Upper MI at 12Z Saturday will deepen as it rapidly progresses into QC. A full-latitude cold front will arc southwestward, crossing the eastern Great Lakes and Midwest on Saturday. The trailing portion will slow its southern movement over TX and likely be modulated by convective outflows.

TX to the Lower MS Valley

Primary changes are to add a CIG1 area for very large hail potential in TX, and shift/expand the cat 2-SLGT risk north-northeast per latest guidance.

While TX will largely remain within a flat to low-amplitude mid-level ridge between the aforementioned troughs/lows well to its north and west, seasonably rich low-level moisture atop an undercutting cold front should support regenerative convection through much of the period. With the west-southwesterly mid-level flow regime, steep mid-level lapse rates will be maintained over the pre-convective warm sector. Low-level flow will become increasingly weak and diffluent, yielding a favorable deep-layer wind profile for hail growth. Primary uncertainty is the degree of surface-based development towards late afternoon/early evening along the composite front/outflow. Current indications are that CIG2-type giant hail potential might evolve with more discrete/isolated convection in the south-central TX vicinity. For now, will incrementally add a CIG1 and defer to later outlooks for a possible categorical upgrade.

Farther east-northeast across the Lower MS Valley, clusters may be consolidating into line segments by mid-late morning Saturday. These may yield an increase in mainly damaging wind and brief tornado potential as the warm/moist sector destabilizes downstream. An extensive swath of widespread convection is anticipated during the afternoon. But this should become increasingly aligned with the deep-layer shear vector. In conjunction with decreasing low-level hodograph curvature, setup may only favor sporadic damaging winds before storm intensities wane after sunset.

OH Valley to the Lower Great Lakes

No adjustment has been made to the level 2-SLGT risk area. At least scattered convection should be ongoing upstream over parts of the Midwest and Mid-South along/ahead of the aforementioned cold front. This activity may not entirely decay, with renewed storm development possible along the large-scale outflow that will probably remain displaced appreciably east of the front. Where adequate insolation can occur amid steep mid-level lapse rates, an uptick in storm intensity should occur midday into the afternoon. Overall amplitudes still seem to favor non-significant severe, but a scattering of damaging winds, a couple tornadoes, and isolated marginally severe hail all appear plausible. These threats should wane after sunset and with eastern extent towards the Appalachians.

You are looking at an outlook that is part of the medium range forecast (the outlook for days 4-8). The most important thing to note is that lack of a risk does not mean zero risk. Generally speaking, confidence has to be pretty high for the Storm Prediction Center to have an outlook area this far into the future.

Valid 081200Z - 131200Z

DISCUSSION

Sunday/Day 4 and Monday/Day 5

A moist airmass in the Gulf Coast region on Sunday will advect northward into the east-central U.S. on Monday. Over the top of this airmass, west-southwesterly mid-level flow will be in place. Although large-scale ascent is forecast to be limited on both days, isolated strong to marginally severe thunderstorms will be possible in the afternoon in areas that heat up sufficiently. The greatest potential for severe storms appears to be on Monday afternoon in the Ark-La-Tex, where moisture and low-level flow are currently forecast to be maximized.

Tuesday/Day 6 to Thursday/Day 8

On Tuesday, model forecasts move an upper-level system across northern Mexico, and retain southwesterly mid-level flow over much of the south-central U.S. A moist and unstable airmass is forecast over much of the southern and central Plains eastward into the lower to mid Mississippi Valley. It appears that large-scale ascent associated with the upper-level trough will gradually increase over the southern and central Plains on Tuesday. In response, scattered thunderstorms should develop over parts of the moist sector Tuesday afternoon and evening. Although model forecasts have slowed the progression of the upper-level low, a belt of strong mid-level flow is still forecast over the south-central U.S. on Tuesday. This suggests that deep-layer shear will support severe thunderstorm development, potentially across a broad area. The severe threat is expected to continue from evening into the overnight period as the upper-level trough approaches.

On Wednesday, the upper-level trough and an associated cold front is forecast to move into the western Gulf Coast states. Ahead of the system, a moist and unstable airmass appears likely by afternoon. Thunderstorms that develop near and ahead of the front could have a severe threat. However, there are still questions about the timing of the trough and front. If model runs continue to suggest that the system will move into the western Gulf Coast states on Wednesday, then a risk area may need to be added. An isolated risk may also develop on Wednesday northeastward ahead of the front in parts of the Tennessee and Ohio Valleys.

On Thursday, the upper-level trough is forecast to move into the eastern U.S., as the cold front moves offshore into the western Atlantic. Thunderstorms with an isolated severe threat would be possible along parts of the Eastern Seaboard before the front passes. However, uncertainty at this extended range is considerable.
