6/25 – Payton’s Tuesday Afternoon Forecast
It’s very hot this afternoon with heat indices over 100 in many locations. It’s very hazy with dust in the atmosphere, and nothing on radar right now. It’s possible we see a few t-storms develop later this afternoon and evening. The strongest storms could produce gusty winds and very heavy rainfall. Meanwhile, a weak shortwave will track across east Texas, Arkansas and northern Louisiana. There is a marginal threat for severe weather, but the potential appears to be on the low-end.
The remainder of the week will be characterized by upper level high-pressure building across the southern half of the country from Texas to the East Coast. It will be a daily battle between daytime heating induced convection and subsidence aloft. The high-pressure will weaken heading into the weekend as an upper-level disturbance will track out of Canada across the northeastern U.S., eroding the high-pressure across the southeastern US. This will allow strong daytime heating to produce numerous afternoon thunderstorms. Expect this summertime pattern to persist into at least the first half of next week.
