KEY MESSAGES

- Headline heat sets in to start the new week.

- Rain chances are sporadic after today, with isolated to scattered storms possible early in the week, and again late in the week.

DISCUSSION

Issued at 100 AM CDT Sat Jul 25 2026

Though showers have dwindled for the time being, some energy within the northwest flow aloft will initiate another round of showers/potential thunderstorms late tonight into Saturday. Pops still look to peak around 60% with PW's pushing 2", so locally/efficient rain producers will be the most likely storm hazard, should one occur.

The strength of the broad Western U.S. ridge aloft further envelops its grip eastward/across our FA during the first half of the week. As a result, our temps/humidity will build as well, with peak headline heat indices up to around 110 degrees possible, particularly Monday-Tuesday. Isolated storm chances within this time period will serve only to reinforce the sticky high humidity, offering little relief.

The high retrogrades over the latter half of the week, backing off its peak intensity here but remaining warm with highs in the lower half 90s. While much of this time period looks dry, some modeling suggests a more robust wave dives south and pushes a cold front across the Ohio Valley next weekend; expect storm chances then to be on the increase if this model signal holds.

AVIATION /12Z TAFS THROUGH 12Z SUNDAY/

Issued at 100 AM CDT Sat Jul 25 2026

Mid-high level VFR bases will persist today, but scattering these out tonight will occur, which may leave some fog potential. Some lingering shower/storm activity is possible until then, especially today during the daylight hours. Though a possible storm that might offer otherwise, it would appear the bulk flight transit will operate with Visual Flight Rules in effect, excepting if fog restricts vsbys toward the end of the planning phase hours of the forecast.
