Outlook for Friday, July 3

Outlook Summary

A swath of damaging to severe gusts is expected across southern Lower Michigan over the next few hours. Scattered damaging gusts are also likely over portions of the Mid Atlantic. Otherwise, scattered wind damage and large hail are still expected from parts of Nebraska into Iowa today. Isolated to scattered severe storms remain possible extending eastward from the northern/central Plains into the Midwest and Tennessee Valley.

THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS FOR PORTIONS OF EASTERN NEBRASKA INTO WESTERN IOWA AND SOUTHERN LOWER MICHIGAN

### SUMMARY

A swath of damaging to severe gusts is expected across southern Lower Michigan over the next few hours. Scattered damaging gusts are also likely over portions of the Mid Atlantic. Otherwise, scattered wind damage and large hail are still expected from parts of Nebraska into Iowa today. Isolated to scattered severe storms remain possible extending eastward from the northern/central Plains into the Midwest and Tennessee Valley.

20Z Update

The main change made to this outlook was to upgrade southern Lower MI to a Category 3/Enhanced Risk, driven by 30 percent/CIG1 wind probabilities. A cold-pool-driven MCS, with some bowing tendencies and a history of producing numerous measured gusts in the 60-70 mph, is rapidly approaching southern Lower MI. KGRR inbound velocity data shows a rear-inflow jet exists with this MCS, and surface observations/latest mesoanalysis show a favorable environment in place for bow-echo persistence. Surface temperatures are exceeding 90 F in spots, amid 70-75 F surface dewpoints, yielding a gradient of 1500-3500 J/kg MLCAPE. Up to 30 kts of effective bulk shear coincides with this buoyancy gradient, with vectors oriented normal to the MCS leading-line orientation. Therefore, the expectation is for a damaging wind swath to occur over southern Lower MI with the passage of this MCS. At least scattered gusts will likely exceed 50 kts in intensity, and a few of these gusts may exceed 75 mph.

30 percent wind-driven probabilities were also added over portions of eastern PA into far southeastern NY and NJ, where surface temperatures are exceeding 100 F in spots ahead of a developing multicellular cluster. While vertical wind shear is modest, the well-mixed boundary layer is yielding low-level lapse rates well over 8 C/km on a widespread basis, with corresponding DCAPE approaching 1500 J/kg. As such, several of the stronger storm cores may produce wet downbursts capable of at least tree/wire damage on a scattered basis, and a few severe gusts are also possible.

Otherwise, the previous forecast (see below) remains on track.

.PREV DISCUSSION… /ISSUED 1100 AM CDT Fri Jul 03 2026/

SD/NE

Water vapor loop shows a weak shortwave trough over central WY approaching the Black Hills region. This, along with remnant outflow boundaries from recent convection, will aid in the development of scattered thunderstorms over western SD/NE by mid/late afternoon. Steep mid-level lapse rates and supercell structures will promote the risk of very large hail in the initial storms over the Black Hills. Activity is expected to organized into a bowing MCS during the evening and track roughly along the NE/SD border with a risk of severe wind and hail.

NE/IA/Northwest MO

Moderately strong southerly low-level winds over KS will maintain a hot/humid air mass across southeast NE today. Thunderstorms are expected to intensify along pre-existing outflow boundaries by late afternoon and develop/move into IA. Large CAPE in this region (MLCAPE > 4000 J/kg) and sufficient westerly flow aloft will pose a risk of supercells capable of large hail and damaging winds through the evening hours.

IA/IL/IN/MI/OH

A remnant outflow boundary is also tracking eastward across the MS river into northern IL. The air mass ahead of this boundary is very moist and unstable with dewpoints in the mid 70s and peak diurnal CAPE values expected to exceed 3500 J/kg. Models differ on convective evolution of storms that form in this regime, but there is potential for an upscale-growing MCS producing a swath of wind damage from northern IL into parts of IN/MI and northwest OH this evening.

NY/PA/NJ

Hot and humid conditions are present across much of the northeast states today, with full sunshine leading to steep low-level lapse rates and moderate CAPE. It is unclear how many thunderstorms will form in this region today given weak forcing. However, the environment is conditionally favorable for damaging winds in any convective clusters that can persist.

TN Valley/Southern Appalachians

A widespread moist and unstable air mass will aid in the development of disorganized and slow-moving thunderstorms again this afternoon and early evening. Weak winds aloft suggest chaotic storm evolutions, but the strongest cells will pose a risk of locally damaging winds gusts and small hail throughout the area.

Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1232 PM CDT Fri Jul 03 2026

Valid 041200Z - 051200Z

THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS FROM THE UPPER OHIO VALLEY INTO THE MID ATLANTIC…AND OVER THE CENTRAL PLAINS

### SUMMARY

Clusters of storms may evolve across parts of the Allegheny Plateau into Mid Atlantic, and across the central Great Plains Saturday afternoon and evening, posing a risk for damaging wind gusts. Large hail is also possible across the Great Plains.

Synopsis

An upper trough will be located over eastern Canada, with southern periphery sweeping across the Northeast with 30 kt midlevel westerlies extending as far south as PA/NJ. To the west, a weak upper trough will move across the northern and central Plains, with embedded disturbances related to thunderstorms into parts of the Midwest. Relatively cool temperatures aloft will exist across the Plains region, aiding destabilization.

At the surface, a trough will extend from the TX Panhandle into MO, IL, and IN, with a moist and unstable air mass nearby. Easterly winds north of this trough will maintain moderate moisture levels into the central High Plains. A surface trough will also deepen over the Northeast and Mid Atlantic during the day, providing a focus for storms during the afternoon from VA into PA/NJ.

PA…VA…MD…DE…NJ

Substantial moisture and instability will exist across the region, with tall CAPE profiles and 3000-4000 J/kg MUCAPE common with 70s F dewpoints and daytime heating. Storms may develop in several areas, including southern NY into PA and OH, and, within the trough VA into PA/NJ.

CAMs generally suggest scattered cells developing by mid afternoon over much of VA and into PA, MD, DE and NJ. Scattered wind gusts of 40-50 kt appear likely, with isolated stronger gusts. Weak westerlies aloft may support slow east/southeastward moving cells.

CO…NE…KS

Scattered storms are forecast to develop from southeast WY into the Front Range, as well as western NE, during the afternoon beneath cool temperatures aloft and where low-level easterlies will aid moisture advection into the heated air mass. Directional shear may favor a few cells capable of severe hail, including near the Colorado Springs area. Addition cells or clusters may spread southeastward across western NE and northwest KS, with damaging gusts possible.

A more substantial severe risk may develop into south-central KS and perhaps far northern OK late in the day. Here, locally larger SRH will exist north of a weak surface low. Instability will be large as temperatures warm into the 90s F and dewpoints remain in the upper 60s F. Veering wind with height and effective shear near 40 kt suggest a few supercells initially, with large hail and locally damaging wind gusts. A brief tornado cannot be ruled out. During the evening, CAMs suggest an MCS may develop, dropping southeastward across southern KS, including the Wichita area, and into northern OK. Damaging wind gusts would be the main concern.

Parts of Central MO

CAM signals are mixed with timing of convective systems near the surface trough. However, strong instability will be present across the entire region. Depending on later model output, the Slight Risk may need to be extended farther into MO/I-70 corridor as predictability increases.

Valid 051200Z - 061200Z

THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS OVER PARTS OF THE MID ATLANTIC REGION

### SUMMARY

Developing thunderstorm clusters may pose a risk for damaging wind gusts across parts of the Mid Atlantic and parts of the southern Great Plains Sunday afternoon and evening. Isolated severe storms may affect northern North Dakota late.

Mid Atlantic States

Although wind fields aloft will weaken compared to the previous day as the upper trough lifts out of the Northeast, upper 60s to low 70s F dewpoints will remain over much of the region. Afternoon storms are likely to develop from PA southward across the Appalachians, and these will move eastward into a zone of strong heating/steep low-level lapse rates into MD/VA. Gusty winds are likely, some damaging through the evening.

Northeast NM into northwest TX

East to southeast surface winds will prevail across the southern Plains on Sunday, which will aid westward moisture advection into NM. Shear will be weak, but southeastward-propagating clusters of storms appear likely late in the day and into the night as storms move into TX. Sporadic severe gusts may occur.

Northern ND

A substantial upper trough will move into the Canadian Prairies late on Sunday, with the base of this trough sweeping across MT and ND overnight. A cold front will develop into far eastern MT and western ND late in the day, proceeding toward the Red River by Monday morning. Forecast soundings show moderate instability developing, with veering winds with height and hodographs favorable for slow-moving supercells. Aiding any such development into the night will be a nocturnal low-level jet. Isolated large hail appears most likely.

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.

Day 4-8 Convective Outlook NWS Storm Prediction Center Norman OK 0402 AM CDT Fri Jul 03 2026

Valid 061200Z - 111200Z

DISCUSSION

Medium-range guidance suggests that a modest mid-level ridge, along an axis from the eastern Great Basin into the Upper Midwest by early next week, may gradually become suppressed by a low-amplitude short wave trough emerging from the Great Basin by the middle of next week. It appears that this will occur as a much more substantive trough and embedded low, within the stronger westerlies confined to the higher latitudes, progress inland across British Columbia and the Canadian Rockies. This could be accompanied by some potential for organized severe thunderstorm development across parts of eastern Montana into the Dakotas by next Tuesday and/or Wednesday, but enough spread persists within latest model output to preclude 15 percent or greater severe probabilities at this time.

A preceding trough within the stronger westerlies is forecast to slowly progress east of the Canadian Prairies through Hudson Bay, Ontario, Quebec and the remainder of the eastern Canadian Provinces by late next week. It is possible that a corridor of boundary-layer moistening and destabilization ahead of an associated cold front could support increasing risk for thunderstorms across parts of the lower Great Lakes through New England by next Thursday into Friday. However, the extent of this potential, and the degree to which it could pose a risk for damaging wind gusts remains uncertain at this time.

Otherwise, severe potential in lower-latitudes, if any, will likely generally be associated with sub-synoptic developments yet to evolve and of rather low predictability at this time range.
