8/31 – Rob Knight’s “Hot & Humid” Midday News Forecast

The combination of moisture flow and daytime heating will pop afternoon showers/t-storms as high temps will max out in the low 90s. Heat index values in the 100-105 range are expected. High pressure will be moving towards the area and will be in place by tomorrow and will lower rain chances considerably.

Models show upper high-pressure to the east and west of the area for much of the week. This seems to be the predominant pattern recently. Dry air will be in place Wednesday into Thursday morning s with the moisture levels increasing a bit Friday into Saturday as a shallow frontal boundary moves into the area. This should be enough forcing for some isolated to scattered diurnal convection by Friday, continuing into Saturday, before another boundary moves into the area.
