Houston is trading stormy days for steamy ones this week

HOUSTON, Texas (KTRK) -- Houston is trading stormy days for steamy ones as the first heat dome of summer settles in across Texas this week.

After a stormy start to Father's Day, sunny and drier conditions settled in and we're keeping that theme going this week. Temperatures tonight will fall from the low 90s to mid-upper 70s by Monday morning. It's going to be a warm start to Monday at that mark with the chance for a light passing showers as the gulf breeze gets going. It is going to be breezy Monday with southerly winds around 20 mph. The day will be drier and with more sunshine, allowing for temperatures to climb into the low 90s. We'll have an afternoon heat index Monday between 100 to 105.

What's the outlook for work week?

This week is the first official week of summer, and it's surely going to feel like it! A heat dome will set up over west Texas that will also keep Southeast Texas hot with morning lows starting in the mid-upper 70s and afternoon highs climbing into the low-mid 90s. Humidity levels will remain high enough that some days could have Heat Advisories with a heat index of 108 or hotter.

So, how much rain did the Houston area pick up this past week?

Checking local rain gauges and rainfall estimates from 13 Alert Radar, much of Houston and Harris County picked up between 3 to 7 inches of rain this past week. Some communities saw over 9 inches of rain too. Farther south, some of the highest totals come from Brazoria and Galveston counties with over a foot of rain falling near Seabrook. Houston's official rainfall total for June is nearing 8", which is 4" above normal through the first 20 days of the month.
