FORECAST IN DETAIL

After a very pleasant Sunday with tolerable humidity levels, mugginess returns today. By midweek and probably lasting through the weekend, we’ll add torching heat. There’s no powerful cold front to offer much relief this week, but — on certain days, such as today — a cooling thunderstorm or two could pass by late in the day.

Today (Monday): Peak afternoon temperatures are very close to where they were over the weekend: in the upper 80s to near 90. But today feels several degrees hotter as humidity surges back into the region (dew points rise to around 70). Skies are partly sunny, but a few storms bubbling up in our western areas late in the day could jog eastward into the metro (20 to 30 percent chance). Winds are light from the southeast. Confidence: Medium-High

Tonight: There’s a 20 to 30 percent chance (highest chances in our western areas) of an early-evening storm. Otherwise, skies are partly cloudy with lows in the upper 60s in our cooler areas to the mid-70s downtown. Confidence: Medium-High

Tomorrow (Tuesday): The day is more or less a carbon copy of Monday, but high temperatures may edge a degree or two higher. Once again, an isolated late-day storm or two could pop up, but the majority of the area stays dry. Confidence: Medium-High

Tomorrow night: There might be an isolated evening storm. Otherwise, skies are partly cloudy, and lows range from the upper 60s to the mid-70s, warmest downtown. Confidence: Medium-High

A LOOK AHEAD

Wednesday through Friday are hazy, hot and humid, with highs each day mostly in mid-90s, but it feels closer to 100. Storms chances are pretty low — less than 20 percent Wednesday and Thursday — but could tick up into the 20 to 30 percent range Friday as a weak front inches closer to the region. The nights are muggy during this stretch, with lows in the 70s. Confidence: Medium-High

There is an outside chance a cool front pushes far enough south late Friday that temperatures briefly cool down a little Saturday, with highs in the 80s. But more likely than not, the front stays to our north and both weekend days are hot and humid, with highs in the 90s. With that front around, we’ll have a chance of some late-day storms, but it’s too soon to assign percentages. Confidence: Low-Medium
