Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0100 AM CDT Mon Jun 29 2026
Valid 291200Z - 301200Z
THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS PORTIONS OF THE NORTHERN PLAINS AND UPPER MIDWEST
### SUMMARY
Severe thunderstorms are possible from parts of the northern Plains into the Upper Midwest today. Large hail and severe winds are the primary concerns, though a couple of tornadoes may also occur.
Synopsis
A shortwave trough will advance eastward from the northern Rockies into the northern Plains today. At the surface, a low will move northward out of Nebraska into the Dakotas, with a cold front/dry line extending southward to a secondary low across the central Plains. Thunderstorm activity is likely to be ongoing at the start of the period near the northern surface low across portions of the Dakotas. Additional thunderstorm activity is expected in the wake of the morning convection near the warm front lifting across North Dakota into Minnesota and near the cold front back into portions of the Mid-Missouri Valley and central Plains.
Dakotas/Mid-Missouri Valley/Upper Midwest
Elevated supercell activity is likely to be ongoing at the start of the period across portions of the Dakotas near the surface low and nose of the low-level jet axis. The environment will be characterized by moderate to strong instability and strong deep layer shear. Guidance suggests that this will have the potential to produce large to very large hail and damaging wind.
As the low develops, a warm front will extend into North Dakota/Minnesota by the afternoon. Evolution of the morning activity remains uncertain, but it appears that additional storms will develop near the warm front and back near the low/cold front into the afternoon. Near the warm front, filtered heating through broken low to mid-level cloud cover will allow for moderate instability by the afternoon. A plume of steep low to mid-level lapse rates will advect northward through the afternoon. The favorable thermodynamic profiles and strong deep layer shear around 45-50 kts will support potential for supercells. If these storms can become surface based, they will be capable of all hazards.
Back west near the cold front/low, initial supercells are possible by the afternoon. These will have potential primarily for large hail and damaging wind. Boundary parallel deep-layer shear will likely lead to clustering/upscale growth with time. Strong to extreme instability is expected ahead of the cold front across portions of the western Dakotas into the Midwest. As the low-level jet increases into the evening, it is possible that a corridor of more favorable damaging wind potential (including significant gusts 75+ mph) may evolve. For now, confidence in convective evolution is low with a few CAMs suppressing convection towards the evening along the front amid the strong EML until later in the evening around 06z.
Kansas/Oklahoma/Texas
Isolated high-based thunderstorms are possible near the dryline in Kansas/Oklahoma/Texas. Moderate instability is expected within this region with generally weak deep layer shear. This will likely keep more widespread severe potential low. However, a few stronger storms may be capable of strong winds given deeply mixed profiles. For now, this potential remains too isolated to include probabilities.

Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 0106 AM CDT Mon Jun 29 2026
Valid 301200Z - 011200Z
THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS NORTHERN WISCONSIN INTO THE UPPER PENINSULA OF MICHIGAN
### SUMMARY
Severe thunderstorms will be possible from parts of the central High Plains into the Upper Midwest, and across parts of the Northeast on Tuesday.
Synopsis
An upper low will be present in the Canadian Prairies with a belt of stronger mid-level flow extending into the Upper Midwest. The amplified upper ridge in the Midwest/East will be somewhat suppressed as a result. A stalled surface boundary will be present from the central High Plains into the Upper Midwest. Moderate to strong mid-level northwesterlies will be present across the Northeast with possible MCVs/shortwaves moving into the region.
Mid-Missouri Valley into Upper Midwest
Convection that occurs in Minnesota overnight Monday into early Tuesday is expected to weaken as it moves eastward. Given the weakening and veering low-level jet, it does not appear this activity will have much of an impact on the environment in northern Wisconsin into the Upper Peninsula of Michigan. A stalled surface boundary will be located from northern Nebraska into Minnesota and northwest Wisconsin. Very rich moisture (mid/upper 70s F dewpoints) will exist in the warm sector. With mid-level lapse rates of 7.5-8 C/km, strong to extreme buoyancy will develop by the afternoon. With the main upper low in the Canadian Prairie, large-scale ascent will be subtle/nebulous. That said, convective temperatures should be reached at least locally with additional lift expected from lake breeze boundaries. Most models, including both global/regional models and CAMs, suggest development is probable from parts of northern Wisconsin into the Upper Peninsula. Effective shear of 40-50 kt will promote some storm organization. However, magnitude of buoyancy along with modest low-level flow will likely result in storms becoming outflow dominant. A targeted Slight Risk has been added for this potential. Damaging winds are the most likely hazard with this activity, but isolated large hail could also occur.
Farther southwest into southern Minnesota/Iowa/Nebraska/South Dakota, storm coverage is much less certain. There could be an increase in thunderstorm activity as the low-level jet increases during the evening. Should this occur, damaging winds and perhaps isolated large hail would be possible. Shear will be weaker in these areas and the severe threat will likely remain marginal/isolated.
Northeast
Questions remain as to the timing of MCV/convection moving out of Canada. Given the potential for early precipitation to occur and limit surface-based instability, the Marginal Risk has been maintained for this outlook. Nevertheless, the environment will be favorable for strong to severe storms. Effective shear is expected to be around 50 kt. Damaging winds and large hail are likely the main risks; however, if storm mode is more cellular, a greater tornado risk could also be present. Trends in guidance will need to be monitored.
Colorado/Kansas/southwest Nebraska
A modest lee trough will promote moisture advection into the central High Plains. A subtle shortwave trough moving through the central Rockies may aid in storm development. The timing of storm development is not certain, but most guidance would suggest this occurs at or after 00Z. Steep mid-level lapse rates and moderate deep-layer shear will promote organized storms that will be capable of large hail (isolated to around 2 in.) and severe winds. Low-level shear will be enhanced near the surface trough/low, but concerns over low-level thermodynamics limit confidence in a tornado threat.

NOTE: THE NEXT DAY 2 OUTLOOK IS SCHEDULED BY 1730Z
Outlook for Wednesday, July 1

any severe predictability too low
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 0346 AM CDT Sun Jun 28 2026
Valid 011200Z - 061200Z
DISCUSSION
Relatively little change is expected in the upper-level pattern from mid to late this week. A broad trough in the West will bring southwesterly flow across the Rockies and parts of the Plains. In the East, an upper ridge will persist. During the weekend, models are in general agreement that the upper ridge will flatten and broaden across the southern U.S. This pattern will favor the maintenance of a very moist airmass within parts of the Plains into the Midwest and Southeast. The lack of more notable mid-level and surface features decrease predictability with regard to where severe convection may occur. That being said, subtle surface boundaries/shortwave troughs may promote convective development each day within parts of the Plains/Midwest. Trends in model guidance will continue to be monitored, but confidence remains low in placing severe probabilities.
