Summer has its hold on the south making the heat the main story of this forecast. The culprits of this is our ever present Ridge in that has been sitting over the West and the upper low over Hudson Bay. The low has weakened some allowing for the ridge to expand its influence across more of the south. This has allowed temperatures to increase into the upper 90s and low 100s.
This combined with the moisture has resulted in dangerous heat indices as well. The relief that we may see is some enhanced troughing by our upper low which will work to bring increased storm chances and temperature relief to the region. Let’s break it down below.
Short-Term Outlook
The region will continue to see high temperatures in the upper 90s to low 100s spread across the region as our ridge continues to exert its influence and spread across the region. This combined with the humidity values has led to widespread heat indices values of 100 -105 with locally higher amounts possible. As a result, much of the region is under a heat advisory so extra precaution should be taken to protect yourselves from the heat and prevent heat-related illnesses, whether this be accomplished by taking frequent breaks from outdoor activities, staying well hydrated, and cooling off in any air-conditioned buildings if possible.
Extended Outlook
The heat is expected to stay put through Friday where a subtle pattern shift should result in some relief. Until then, high temperatures and moist air will pose a substantial risk for heat-related illnesses. With more troughing present, we should see a renewal in westerly flow and a reduction in subsidence keeping the heat near the surface. As a result, temperatures will “cool” to the mid 90s.
While this is still hot, this temperature is far more manageable then the upper 90s and low 100s expected in the short term. This relief will be short lived as models are indicating a return to ridging as early as next week and the Climate Prediction Center is calling for widespread above average temperatures for this time of year. Stay safe during these hot conditions everyone!
