KEY MESSAGES

- Heat Advisory remains in effect through Friday as daily heat index values climb to around 100 degrees. Little nighttime relief with lows in the 70s. These hot conditions may linger through the Independence Day weekend, so those with outdoor plans to celebrate the holiday should make efforts to have cooling and hydration options readily available.

- Isolated thunderstorms will be possible during the afternoon/evening hours Thursday through Saturday. Coverage/probability is less than 30 percent and confined to locations along and east of Highway 65 on Thursday and locations along and east of I-49 on Friday and Saturday. There is the potential for a few strong storms with gusty winds the risk, but confidence is low at this time.

- Scattered storms (20-40%) will be possible across the area late this weekend into early next week. Temperatures will return to near normal (upper 80s to lower 90s) early next week.

SHORT TERM /THROUGH TONIGHT/

Issued at 316 AM CDT Wed Jul 1 2026

An upper level ridge of high pressure remains over the region and will remain in place through the rest of the week into the weekend. Overall temperatures today will be very similar to those that occurred yesterday. Early morning temperatures are currently in the middle to upper 70s. Lows this morning will only cool a few more degrees into the lower to middle 70s.

The warm air mass will remain over the area today as 850mb temperatures will be around 20C today. Highs will once again warm into the lower 90s with a few locations possibly warming into the middle 90s this afternoon. Dewpoints are currently in the lower to middle 70s across the area. A drier airmass remains in place in the mid levels of the atmosphere so dewpoints could mix again this afternoon into the upper 60s to lower 70s like yesterday. As a result afternoon/early evening heat index values will once again warm into the upper 90s to near 105 degrees this afternoon. A Heat Advisory remains in effect for the entire area today, and through Friday. The mixing will again allow winds to be gusty at times out of the south to southwest this morning through the afternoon hours with gusts up to around 25 mph at times.

There will be slightly more moisture in the low levels of the atmosphere today, so some diurnal cumulus clouds will be possible today across the area. A cap and drier air in the mid levels will once again keep the area dry today.

LONG TERM /THURSDAY THROUGH TUESDAY/

Issued at 316 AM CDT Wed Jul 1 2026

The upper level ridge of high pressure, with the high centered to the east of the area, will remain in place across the region through the rest of the week into the weekend. As a result temperatures each day will be very similar, as highs will continue to warm into the lower to middle 90s each afternoon with lows in the 70s each night. Heat index values in the upper 90s to around 105 degrees will continue to occur each afternoon into the weekend. The Heat Advisory currently remains in effect through Friday evening.

Slightly better moisture will build into the eastern portions of the area on Thursday and across much of the area Friday and Saturday. The cap will also weaken with peak heating each afternoon/evening Thursday through Saturday. Lift will remain more limited with the ridge over the area and the storm track to the north. Some isolated storms will be possible each afternoon as instability increases and the cap weakens each day but coverage will be limited. These isolated thunderstorms will mainly be possible (< 30%) along and east of Highway 65 on Thursday and along and east of I-49 on Friday and Saturday. Shear will be weak, but Theta-E difference will be strong enough to support the potential for a few strong storms with gusty winds the risk. Locally heavy rainfall will also be possible as storm motions will be slow. Coverage will again be limited so not all locations will be impacted.

Late this weekend into early next week the ridge of high pressure will move off to the east. Temperatures will be a few degrees cooler with highs returning to near normal with readings in the upper 80s to the lower 90s. The ensemble model members show a weak upper level disturbance moving through the region Sunday into early next week. There are still some differences between the model members on the exact timing track of the system. Some scattered storms will be possible (20-40%) as the disturbance moves through late this weekend into early next week.

AVIATION /12Z TAFS THROUGH 12Z THURSDAY/

Issued at 450 AM CDT Wed Jul 1 2026

VFR conditions will occur across the area today through tonight. Some scattered diurnal cumulus clouds will develop this morning and afternoon with cloud based around 5kft. Winds will be out of the south to southwest and gusty at times this morning and afternoon. Southerly winds will occur this evening tonight with mostly clear skies.
