DISCUSSION

(Tuesday through next Monday) Issued at 1038 PM CDT MON JUL 27 2026

Water vapor imagery this evening reveals a strengthening upper level ridge across the Four Corners region and an upper trough pushing through the Great Lakes region. Several shortwaves will rotate around the periphery of the high, which will keep low to medium chances for showers and storms in the forecast. Tuesday's activity looks to remain east of the region as the ridge shifts slightly east across the Southern Plains. By mid-week, the ridge begins to retreat south and west as the trough along the East Coast deepens and pushes a front through the region. This will allow the aforementioned shortwaves to inch closer to the region, bringing better chances for showers and storms, generally to the south of the front, through Thursday. Another upper trough cuts across the Plains into the Ohio Valley over the weekend. This will send a front our way, leading to increased rain chances over the weekend.

The main story over the next couple of days will be our increasing heat risk. Temps in the upper 90s along with muggy conditions will warrant a major heat risk across most of the region Tuesday with heat indices approaching 110 degrees. The latest ECMWF EFI hints at an unusually warm day tomorrow, especially across the southern half of the CWA. Highs tomorrow will be about 10 degrees warmer than usual for this time of the year. As a result, the Heat Advisory remains in effect through Tuesday evening. We will knock off a couple of degrees by mid week as the ridge retreats back west. High temps look to settle into the upper 80s to low 90s by Friday.

FIRE WEATHER

A warm and humid air mass will keep fire weather concerns in check for the week. MinRH values are expected to remain above 50 percent through Wednesday. Some drier air begins to work in from the east on Thursday and Friday with RHs dropping to around 40 percent. However, winds will be light enough to negate any fire weather impacts.
