THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS THIS AFTERNOON AND EVENING ACROSS PORTIONS OF WEST CENTRAL TEXAS

### SUMMARY

Scattered thunderstorms are possible across portions of Texas centered on the Edwards Plateau. Hail and gusty winds are the primary threats.

West Central TX

Morning radar/satellite imagery shows a slow-moving MCS over western north TX, tracking slowly southeastward. This activity is associated with a weak upper low and related low-level warm advection over the region. An outflow boundary along the southern flank of this MCS will likely be the focus for afternoon thunderstorm development in a moist and moderately unstable air mass. Storms that form will track southeastward across the SLGT risk area, posing a risk of damaging wind gusts and some hail.

CO/NM

Scattered afternoon high-based thunderstorms are expected to form over the mountains and foothills of northern NM/southern CO. These storms will be in a deeply mixed air mass, capable of locally gusty winds and hail for a few hours before weakening.

Upper MS Valley

A surface cold front will sweep eastward across the upper MS Valley this afternoon as an upper trough currently over the Dakotas approaches the region. Scattered showers and thunderstorms are expected to form along/ahead of the front during the peak-heating period. The strongest cells may pose a risk of hail and gusty winds. But overall the risk is expected to be rather marginal.

THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF THE UPPER MIDWEST

### SUMMARY

Thunderstorms associated with large hail and severe wind gusts, and perhaps a tornado or two are expected on Wednesday in parts of the Upper Midwest.

Upper Midwest

A belt of strong mid-level flow will be in place on Wednesday across the far northern U.S. Within the flow, a 60 to 80 knot mid-level jet is forecast to move eastward across far southern Saskatchewan. The exit region of this feature will overspread the upper Mississippi Valley during the day, strengthening large-scale ascent and deep-layer shear. At the surface, a cold front will advance eastward through the eastern Dakotas. Ahead of the front, surface dewpoints will likely reach the lower to mid 60s F from the mid Missouri Valley northeastward into the upper Mississippi Valley. During the afternoon, surface-based thunderstorms are expected to form along the western edge of the moist airmass, from eastern South Dakota into western Minnesota. These storms are expected to gradually increase in coverage, moving eastward into the upper Mississippi Valley during the late afternoon and early evening.

NAM forecast soundings near the instability axis at 00Z/Thursday from central Minnesota into far northwest Iowa have MLCAPE in the 1500 to 2500 J/kg range, 0-6 km shear around 45 knots, and 700-500 mb lapse rates near 7.5 C/km. This environment will favorable for severe storms. The stronger cells could become supercellular and have a large hail threat. Hailstones greater than 2 inches in diameter will be possible with supercells that form in areas that destabilize the most. Some model solutions suggest that cells could be separated enough to favor discrete modes. By early evening, forecast soundings increase 0-3 km storm-relative into the 200 to 250 m2/s2 range. These factors would support an isolated tornado threat with the more intense supercells. A wind-damage threat will also be possible with supercells, and with organized short line segments. The severe threat should continue into the mid to late evening as storms move eastward into the far western Great Lakes region.

Outlook Summary

Thunderstorms associated with large hail and severe gusts will be possible on Thursday in parts of the central Plains and mid Mississippi Valley. Marginally severe storms will also be possible in parts of the Great Lakes and central High Plains.

Valid 131200Z - 141200Z

THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF THE CENTRAL PLAINS AND MID MISSISSIPPI VALLEY

### SUMMARY

Thunderstorms associated with large hail and severe gusts will be possible on Thursday in parts of the central Plains and mid Mississippi Valley. Marginally severe storms will also be possible in parts of the Great Lakes and central High Plains.

Central Plains/Mid Mississippi Valley/Great Lakes

An upper-level trough will move eastward into the Great Lakes region on Thursday, as a cold front advances southward into the central Plains, mid Mississippi Valley and southern Great Lakes. Along and to the south of the front, surface dewpoints in the upper 60s and lower 70s F, will likely contribute to the development of moderate instability by afternoon. As surface temperatures warm during the day, thunderstorms are expected to form along the front, with several clusters of strong to potentially severe storms moving southeastward across the central Plains, mid Mississippi Valley and southern Great Lakes region.

The greatest potential for severe storms appears to be from northeast Kansas east-northeastward into north-central Illinois where the models suggest that the strongest instability will develop. Along the front, the NAM has the strongest instability in northeast Kansas, where MLCAPE is forecast to peak in the 4000 to 5000 J/kg range in the late afternoon. At that time, the NAM forecast sounding at Kansas City has gradually veering winds with height, 0-6 km shear near 30 knots, and 700-500 mb lapse rates around 7.5 C/km. This environment would support a potential for supercells with large hail. However, with northwest mid-level flow aloft, persistent convective clusters may tend to organize into line segments with wind-damage potential. The chance for severe wind gusts could extend east-northeastward along a narrow corridor of instability into north-central Illinois, northern Indiana and Lower Michigan. Due to more widely-spaced storms in the Great Lakes region, the threat may be more isolated with northeastward extent.

Central High Plains

An upper-level ridge is forecast to move eastward through the Rockies on Thursday. A narrow axis of maximized instability and moisture is forecast by afternoon to the east of the ridge from northern Kansas into northeast Colorado and far southwest Wyoming. As surface temperatures warm during the day, isolated to scattered thunderstorms may develop near the instability axis. Although flow is forecast to be relatively weak in the low-levels, speed shear in the mid-levels could be enough for an isolated severe threat. Hail and/or marginally severe wind gusts would be the primary threats.

Valid 141200Z - 191200Z

DISCUSSION

Friday/Day 4 to Sunday/Day 6

From Friday to Sunday, an upper-level ridge is forecast to move eastward from the Great Plains to the northeast, as a shortwave trough moves northeastward from the Four Corners to the upper Mississippi Valley. A somewhat narrow corridor of instability, oriented from southeast to northwest, is forecast ahead of the trough on Friday and Saturday. As the trough moves out into the central High Plains, isolated to scattered thunderstorms appear likely to develop across parts the instability corridor, with the greatest convective coverage likely in the evening and overnight period when the airmass is less likely to be capped. A severe threat could be associated with the stronger cells within the clusters that form near areas of moderate to strong instability. The main uncertainty involves the position of the instability axis relative the approaching trough. Some models suggest that the two will be far removed from each other, which introduces a lot of uncertainty concerning any potential scenario.

On Sunday, the shortwave trough is forecast to move into the upper Mississippi Valley, and out-run the stronger instability located in the mid Missouri Valley. Strong to potentially severe storms may still develop in association with the trough, but the forecast position of the warm sector relative to the trough introduces uncertainty into the forecast.

Monday/Day 7 and Tuesday/Day 8

On Monday, an upper-level trough is forecast to move into the western U.S., as southwest mid-level flow remains over much of the central U.S. It appears that a moist and unstable airmass will be located from the central Plains into the upper Mississippi Valley, where isolated to scattered strong to severe storms will be possible each day. However, model spread is large concerning the timing of shortwave features and the positioning of instability. For this reason, uncertainty is considerable for Monday and Tuesday.
