Pattern Change with Unsettled Weather Wednesday through Next Weekend

qpf_acc-us_sc

Tonight through Tuesday will feature southerly winds and a quick return to summer conditions. The southerly winds will bring oppressive humidity values and the warmer temperatures back into Texas. The southeastern half of Texas didn’t get much, if any, relief in the heat but hopefully humidity values were a bit lower today. The northwest half of the state did get to enjoy about 36 hours of cooler/less humid weather. That will be long gone by Tuesday as surface dewpoints quickly climb back up into the 60s and 70s. This will occur ahead of a major pattern change which will result in unsettled weather for the second half of this upcoming week into next weekend.

The upper-level flow (jetstream) is fairly zonal across the northern United States. Winds are nearly zero over the southern United States, but are not your classic heat ridge with a high pressure in place. As you might expected our weather is fairly quiet when in this pattern since the jetstream is well to our north. The jetstream contains storm systems and thus we won’t have any widespread, organized precipitation chances through Tuesday.

That begins to change on Wednesday and especially so by the end of the work week. The subtropical jet stream becomes active from the eastern Pacific through northern Mexico into the northern half of Texas and Oklahoma. At the same time a cool front may be slowly moving south into Texas. Combined with copious amounts of moisture we should see several days of precipitation chances and hopefully some cooler weather. We’re not talking about a constant washout or 100 percent rain coverage/chances. Nor are we talking about a major cool-off with jacket weather. Considering we’re still several days out specific rain chances and locations will be refined as we get into the work week.

The extended range of the forecast also looks a bit interesting. Weather models differ on the exact scenario but it appears an upper level low will have a large role in our weather next weekend. Depending on the low’s position and the timeline we could see a fairly widespread rain event. Regardless of how the forecast plays out it is looking fairly unsettled with rain chances. Temperatures should stay on the cooler side in the 70s and 80s where we see rain chances, but the humidity will stay up there as abundant moisture remains in place.
