THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF THE SOUTHERN HIGH PLAINS
CORRECTED FOR WORDING
SUMMARY
Thunderstorms associated with severe wind gusts and a tornado threat are expected this evening into tonight from parts of New Mexico northeastward into the southern High Plains. A more isolated severe threat will be possible in parts of the Desert Southwest this afternoon.
Desert Southwest/Southern Rockies/Southern High Plains
A mid-level shortwave trough will move across California into the Desert Southwest today. Ahead of the system, a sufficiently moist airmass will be in place across parts of southern and central Arizona, where scattered thunderstorms will develop during the afternoon. Large-scale ascent and strong deep-layer shear will support an isolated severe threat with cells that initiate and develop within weak instability. Supercells with potential for isolated severe wind gusts will be possible as a larger-scale band of storms becomes more well-defined.
Ahead of this convective band, moisture advection will take place today in the southern High Plains of eastern New Mexico and west Texas. Surface dewpoints will gradually increase into the lower to mid 60s F. Along and near the moist axis, moderate instability will develop in the late afternoon and early evening. The large-scale line segment is expected to become increasingly organized as it approaches the instability axis. The potential for severe wind gusts and a few tornadoes will likely become maximized as the line moves through the stronger instability this evening over eastern New Mexico and west Texas.
RAP forecast soundings this evening from Roswell, NM northward to Clovis, NM have 0-6 km shear in the 55 to 65 knot range with some veering winds with height and substantial low-level speed shear. 0-3 km storm-relative helicity is forecast to reach the 250 to 350 m2/s2 range in parts of eastern New Mexico in the early to mid evening. This will support a tornado threat with supercells that form within the large-scale band. Severe wind gusts will also be possible with the more intense parts of the line segment. Severe wind gusts above 70 knots may occur with the faster-moving bowing structures. The severe threat may continue into the overnight period as the line moves northeastward into northwest Oklahoma and southern Kansas.

Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 0102 AM CDT Sun Nov 01 2026
Valid 021200Z - 031200Z
THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS OVER MUCH OF OKLAHOMA…NORTHERN TEXAS…AND SOUTH-CENTRAL AND EASTERN KANSAS
### SUMMARY
Scattered severe storms are expected across parts of the central and southern Plains late Monday afternoon into the evening, with damaging wind gusts and a few tornadoes the main threats.
Synopsis
A deep upper trough will move out of the Rockies and into the Plains, with a leading speed max moving swiftly across western TX and toward the MO Valley during the day. Meanwhile, a stronger speed max will move across NM and into KS, OK, and northwest TX by late in the day, and across the remainder of KS and OK overnight.
A surface low will deepen across central NE, with a cold front moving into western NE and KS. A dryline will extend roughly from central KS into western OK and west-central TX by 00Z, with mid 60s F dewpoints across the warm sector. A 50-60 kt southerly low-level jet will develop late in the day into the overnight period, also aiding northward advection of moisture. At least a narrow zone of supercell potential is evident near the dryline late in the day, with a few tornadoes and damaging wind possible. The severe risk should persist through the late evening with damaging winds and possible QLCS storm mode, along with an isolated tornado risk.
Parts of northern TX across OK and into eastern KS
Capping due to relatively cool boundary-layer temperatures will inhibit storms for much of the day, with a zone of steeper low-level lapse rates near the dryline. Initial cell development is expected there, from south-central KS into western OK and northwest TX after 21Z, with increasing coverage of storms through the evening as the system continues eastward. Effective SRH of 200-300 m2/s2 will be common, though effectiveness away from the dryline will depend on how warm the boundary layer becomes. At the very least, initial cells would appear to have a tornado risk, with sufficient instability of 1000-1500 J/kg. A conditional risk of an EF2 tornado exists due to favorable shear, and depending on destabilization. Storms may become more linear with time as they move across OK, north TX and eastern KS, with decreasing instability after 06Z.

Scattered storms will occur from the Sabine and Lower Mississippi Valleys northward into the Mid Mississippi Valley on Tuesday. A few thunderstorms may produce damaging gusts.

Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0232 AM CST Sun Nov 01 2026
Valid 031200Z - 041200Z
THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS OVER PARTS OF THE LOWER TO MIDDLE MISSISSIPPI VALLEY AND TOWARD THE SABINE RIVER
### SUMMARY
Scattered storms will occur from the Sabine and Lower Mississippi Valleys northward into the Mid Mississippi Valley on Tuesday. A few thunderstorms may produce damaging gusts.
Discussion
On Tuesday, an amplified upper trough will move east out of the Plains and toward the MS Valley, with an expansive region of south/southwest winds aloft from the Sabine Valley to the Upper Great Lakes. Southerly surface winds will further transport moisture northward with 60s F dewpoints to the Mid MS Valley, and upper 60s F into the Lower MS Valley.
The elongated surface trough/wind shift will support rain and thunderstorms through the period as the trough gradually shifts east. Some diurnal increase in storm intensity is possible, and the greatest potential for isolated severe storms should be over southern parts of the MS Valley and to the Sabine River where instability will be strongest. Wind profiles will be marginally supportive of severe storms with 30-35 kt effective shear over southern areas. Farther north into MO and IL, shear will be stronger, but instability will be quite weak. Strong wind gusts appear to be the main threat.

NOTE: THE NEXT DAY 3 OUTLOOK IS SCHEDULED BY 1930Z
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.
When no specific risk areas are shown, you might see one of these phrases:

Day 4-8 Convective Outlook NWS Storm Prediction Center Norman OK 0331 AM CST Sun Nov 01 2026
Valid 041200Z - 091200Z
DISCUSSION
An upper trough will move from the MS Valley toward the OH Valley and Great Lakes on Wed/D4, with a secondary trough moving across the Four Corners and into the Southern Plains. An occluded surface low will also move across the upper Great Lakes, with a cold front moving across the OH/TN Valleys and toward the Appalachians. While low-level moisture will support rain and thunderstorms along this front, the lifting of the upper system and weak instability will result in decreasing severe risk. This weakening trend should continue into Thu/D5 as the front moves across the Mid Atlantic and off the East Coast. Behind these systems, the pattern will favor high pressure and minimal chances of thunderstorms.
