Tracking heat and humidity along with storms starting Friday

TONIGHT: Partly cloudy and muggy with lows in the upper 60s. A few storms possible late, especially north of I-70.

TOMORROW: A few showers and storms early, with heat and humidity returning by afternoon. Highs in the upper 80s with a heat index in the low 90s.

EXTENDED: As low level winds kick up tonight, we'll see a few storms work in our direction overnight, especially along and north of the I-70 corridor. We could have some lingering showers and rumbles through late morning, but much of Friday is looking warm and humid as highs bounce back into the upper 80s. The heat index will rise to between 90-92 by late afternoon. A complex of storms developing near a stalled front to our north late Friday night may drop as far south as I-70 again, with heavy downpours and isolated small hail and diminish early Saturday morning. Saturday will be hot and muggy with highs in the upper 80s and a heat index around 93. We may see isolated to scattered redevelopment of storms along the boundary leftover from the morning round, especially late in the day as we reach peak heating. The lack of wind shear overall will limit the severe threat, but storms could be efficient rain producers and cause localized flooding. Our best shot at rain over the weekend will be Sunday through Monday as a more organized low pressure system works east off the Plains, bringing a low chance for severe weather yet again due to the lack of wind shear. That said, water content in the atmosphere will be high again, so local flooding will be the main concern, especially through Sunday night. Scattered storms continue Monday, keeping temperatures in the lower 80s. From there, a larger ridge of high pressure builds right over top of us with a blocking pattern setting up to our west and east, trapping us in some more intense heat for the rest of the week. I expect temperatures to reach the 90s starting Tuesday or Wednesday, with heat indices between 98-101 degrees through late next week.
