Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1239 AM CDT Fri Oct 30 2026
Valid 301200Z - 311200Z
THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF ARIZONA
### SUMMARY
Thunderstorms with isolated severe wind gusts and hail will be possible in parts of Arizona today.
Arizona
An upper-level trough will move northeastward today from the eastern Pacific into California and Arizona. Ahead of the trough, a north-to-south corridor of low-level moisture and instability will be in place over parts of southern and western Arizona. Along the moist axis, surface dewpoints in the 60s F will contribute to weak destabilization by afternoon. As surface temperatures warm, scattered thunderstorm development is expected near the moisture and instability axis. RAP forecast soundings from 22Z to 00Z near this axis have 0-6 km shear in the 30 to 40 knot range with 700-500 mb lapse rates near 7 C/km. This should be enough for a marginal hail threat with rotating cells. Low-level lapse rates will also become steep from the surface to near 850 mb suggesting isolated severe wind gusts will also be possible. The storms associated with any severe threat are expected to remain unorganized.

Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1240 AM CDT Fri Oct 30 2026
Valid 311200Z - 011200Z
NO SEVERE THUNDERSTORM AREAS FORECAST
### SUMMARY
Severe thunderstorms are not expected on Saturday.
Discussion
Shortwave ridging will occur from the Northern Plains to the Upper Great Lakes on Saturday as a shortwave trough exits the Maritimes and multiple waves converge across the West. In the wake of the northeastern trough, high pressure will become centered over the Mid Atlantic, with dry low-level trajectories over much of the eastern CONUS.
Easterly surface winds will maintain a boundary near the Gulf Coast, though southerly winds may bring upper 60s well inland across eastern TX into LA. Here, scattered showers and thunderstorms will be likely within a weak low-level warm advection regime. Lapse rates will be poor with little if any severe potential.
Elsewhere, cool temperatures aloft will exist along the West Coast and into much of the Intermountain West as an amplified upper trough moves ashore late in the day over WA/OR/CA, and another southern-stream wave approaches southern CA and northern Baja overnight. While shear will increase across most of the region, instability will be quite weak, with isolated lightning possible from eastern ID southward across the Great Basin late in the day and overnight.

Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0230 AM CDT Fri Oct 30 2026
Valid 011200Z - 021200Z
THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS OVER MUCH OF CENTRAL AND EASTERN NEW MEXICO…AND SMALL PARTS OF WESTERN TEXAS
### SUMMARY
A few severe storms are anticipated from central New Mexico into parts of western Texas late Sunday into Sunday night.
Discussion
An amplified upper trough will move across the Great Basin on Sunday, while another wave to the south moves across northern Baja CA and into AZ. By late in the day, gusty south winds will increase across the Rockies and into the southern High Plains, as low pressure develops over WY through 00Z.
During the late evening and overnight, a prominent cold front will move out of AZ and into NM as the parent wave aloft continues northeastward across NM and into the central to southern High Plains. The surface low is forecast to deepen overnight into CO, with a surface trough into eastern NM and western TX through 12Z Monday.
After a full day of heating, low-level lapse rates will be steep, and gusty winds overnight should maintain relatively warm temperatures ahead of the cold front. Dewpoints from the upper 40s to mid 50s F should also be maintained ahead of the front, with thunderstorms developing near the cold front after about 03-06Z. Deep-layer shear will be strong, with supercell wind profiles. Instability will be marginal over central NM, perhaps supporting locally severe gusts or marginal hail, with a potentially greater concentration of severe storms into eastern NM where low-level moisture will be more abundant with MUCAPE over 1000 J/kg. The strongest cooling aloft will spread over northern NM and into the TX Panhandle, and this is where a potentially greater hail and wind threat could develop. Both cellular and possibly QLCS storm mode will be possible, with storms tied to the cold front. A small corridor of higher severe probabilities could be added in later outlooks as trends warrant.

Note on Medium Range Outlooks
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:
- Predictability Too Low: This means that severe storms might be possible, but forecasters aren't confident enough about where or when they might occur. Think of it as the models showing different possibilities, like pieces of a puzzle that haven't come together yet.
- Potential Too Low: This means forecasters are fairly confident that widespread severe weather is NOT expected on that day. While isolated storms might still occur, the chance of reaching severe criteria across any given area is very low.

Day 4-8 Convective Outlook NWS Storm Prediction Center Norman OK 0359 AM CDT Fri Oct 30 2026
Valid 021200Z - 071200Z
DISCUSSION
A large positive-tilt upper trough will move into the Plains on Monday/D4, with a surface low moving from the central Plains into the Upper MS Valley. A substantial low-level moisture plume with mid 60s F dewpoints will spread north ahead of the developing low and cold front, aided by 40+ kt south/southwest 850 mb winds. The main severe threat should develop during the afternoon along the cold front, where MUCAPE on the order of 1000 J/kg will be likely. Effective deep-layer shear will be near 50 kt, with sufficient low-level turning with height to support both supercells and linear structures late. Damaging winds and perhaps a couple tornadoes will be possible, with sporadic large hail as well.
By Tue/D5, the trough is forecast to become more amplified, with more of a meridional flow pattern aloft spreading across the MS Valley. Substantial rain and thunderstorms are likely along the cold front and elongated surface trough. There is some potential for damaging winds/bows from eastern TX into AR, LA, and MS, but substantial uncertainty exists given marginal instability and widespread clouds/precip.
This system will generally swing eastward across the southeastern states from Wed/D6 into Thu/D7, with at least low-end potential over some of the Gulf Coast states.
