Scattered rains on Wednesday afternoon will subside into the evening with spotty showers, at best, lingering into the late night hours. While it will be mainly dry through the overnight and early morning hours, partly to mostly cloudy skies will limit overnight cooling. Plan for a daybreak start to Thursday in the upper 70s for most of us once again. We can’t rule out a spotty shower or two, especially closer to the coast, but the morning commute should be a dry, albeit very muggy, drive for most WAFB viewers.
Heading into Thursday afternoon, it’s one more day of scattered rains for the viewing area. The First Alert Forecast posts Thursday afternoon rain chances at 30 to 40 percent across the WAFB area. However, even with clouds and scattered rains, highs on Thursday will reach the low 90s for most WAFB neighborhoods.
But Thursday will be the end of our recent run of scattered rain days. A mid/upper-level ridge of high pressure currently centered to our west will expand eastward as we head into Friday and the weekend. That ridge will put a "soft lid" on the atmosphere that will not only inhibit showers across the WAFB area for Friday and the weekend, but also slow the afternoon cloud development. As a result, the First Alert Forecast has rain percentages at just 10 to 20 percent for the three-day spell. And with less cloud cover, get ready for highs in the mid 90s area-wide with some neighborhoods getting into the upper 90s for one or more of the afternoons.
Our humid Gulf air will remain in place for the weekend too, which means the humidity will be with us through the weekend. You can gear up for muggy mornings with sun-up temperatures in the upper 70s to near 80°. In addition, the humidity will make those mid 90s feel like 100° or more in the shade for extended stretches of hours each day. In fact, Heat Index readings approaching 110° are possible on one or more of the three days. Heat Advisories could be issued as a result.
Around the corner into early next week, we should see the ridge relax and retreat, allowing for a slow return of rain to the region. We are currently calling for rain chances at 20 percent on Monday, 30 percent on Tuesday, and 40 percent on Wednesday. As those rain chances rise, we should see the afternoon highs slip a bit, with mid 90s on Monday easing back to the low 90s by mid week.
The bottom line is we’re in for a run of hot weather, potentially the warmest string of days of the summer.
The National Hurricane Center (NHC) is reporting no new tropical cyclones are expected (in the Atlantic Basin) during the next five days.
