The most significant weather impacts, including thunderstorms and dangerous heat, will occur along and south of the I-20 corridor. Numerous showers and storms are expected this afternoon, with very moist air potentially causing heavy rainfall in slow-moving storms. Storms should diminish quickly in the evening, leaving mostly quiet and humid conditions overnight.
A very moist tropical air mass will continue to flow into the area, pushing the stalled boundary northward. Expect surface dewpoints in the mid to upper 70s and high humidity levels. The extra moisture means extra clouds and storms. And the increased cloud cover and rain will limit daytime temperatures. That said, the increased humidity will give a bump to the Heat Index and Experienced Temperatures.
Next week, an upper-level trough will move eastward, bringing continuous moisture and scattered daily showers and storms. By Tuesday, as what is left of Beryl weakens and turns northeast, we will see a shot for more rain – but the specifics of where that rain will be – and be heaviest – is still TBD.
Speaking of Beryl, it is reorganizing and restrengthening in the Gulf.
While it may be able to strengthen, there may be a bit of a functional limit to just how big – in physical size – it can get.
The upper-level low to the west and the ridge to the east are going to limit the volume the system can grow into, but they will not impact the strength.
In fact, given the direction Beryl is moving and the mid-level and upper-level flow ahead of it, we may see some beneficial venting and pre-conditioning of the atmosphere ahead of Beryl which would allow it to grow – quickly – in strength as it approaches the coast of Texas.
But the area that would be impacted by the strongest part of Beryl would still be small, since the volume of space is limited.
