Highs in the low-to-mid 80s in July? Awesome, right?! Well, maybe not, when you factor in the humidity. Even after days upon days of this moist air mass, getting used to dew points near and above 70 isn’t too easy. We’re going to get some more time to “acclimate” while dodging showers and storms in the days ahead.

Through Tonight: We stay mostly cloudy with scattered showers and thunderstorms in the evening, trending mainly to just showers overnight. While periodic showers remain likely, and may drop heavy rain in spots, not everyone will see much overnight. Lows fall to near 70 in the cool spots, perhaps up closer to the mid-70s downtown. Light south winds help keep us in the soup.

Tomorrow (Tuesday): It’s another mostly cloudy day on average, but we should also see some sunnier times in between the thicker overcast. Any daytime heating just promotes more precipitation, and periods of heavy showers and thunderstorms continue to be likely at times. There are some signs there could be more in the way of widespread rain tomorrow compared to today, but that’ll be hard to pin down for sure until tomorrow. Highs range from near 80 to the mid-80s as a light south wind persists.
