DISCUSSION

(This afternoon through Sunday) Issued at 129 PM CDT MON JUL 27 2026

Upper-level ridging shifts east through the work week, setting the stage for significant heat risk. Tuesday stands out as the hottest and most oppressive day, with highs reaching the upper 90s to near 100 degrees. Combined with dew points in the mid- to upper 70s, heat indices will approach 110. A Heat Advisory has been issued, beginning this afternoon for western areas and expanding area-wide through Tuesday. While the MCS train persists, the primary track appears to remain east of our area on Tuesday, limiting rain chances. However, rounds of showers and storms remain possible as shortwave energy rotates along the ridge's periphery. By mid-week, the ridge suppresses as a trough builds over the East Coast and a deep low develops over New England. This pattern change will allow for a gradual cooldown, with highs trending into the upper 80s and low 90s by Friday.
