Ridging pattern continues to keep day to day conditions very similar. Near record highs and humid conditions will keep afternoon heat index values above 100 across much of the state. Winds remain weak and generally out of the south with an occasional gust. An western wobble and intensification of the h500 ridge will shift afternoon rain chances to northwest, west, and southern ar weds. Cams have honed in on NW ar for the most widespread coverage starting mid-afternoon. This should then slowly spread southward across the state becoming more scattered as it goes. Within any showers or storms an isolated strong wind gust and frequent lightning will be possible. Rainfall totals will likely remain under half an inch bringing no meaningful relief to drought conditions. Any shower activity will begin to dissipate from north to south after sunset.
Mid range model consensus has the h500 ridge continuing to intensify over the region to near record heights over 600dm over the mid- south. Heat headlines will likely need to be extended with some slight changes in the area possible closer to the weekend. Drier air begins to move into the region late thursday and likely shuts off rain chances until late in the weekend. Any recovery of fuels and soil moisture from any precip will quickly eroded as daily soil moisture evaporation rates of near 0.25 in almost equal expected rainfall totals from these showers and t'storms.
Some relief may be in site in the mid to long range models. They are hinting at a more active pattern starting to work its way into the region late in the weekend to next week as the ridge weakens and may allow for a shortwave and attached cold front to introduce limited rain chances across the area. Any relief would likely be short lived as the ridge wants to build back in quickly next week.
Models continue to advertise cooler temps at the end of the period that are replaced with a more realistic well above average temp under the current pattern. This is likely in part due to model climatology that is being skewed by normal temps dropping around 10 degrees by the end of the month. Any advertised heat relief should be taken with a grain of salt until a discernible breakdown in the ridging pattern occurs.

Mostly VFR conditions are expected through the period. With that said, some slight rain and thunderstorms chances are possible for northern and western locations. Periods of MVFR/IFR conditions are possible with shra/tsra. Otherwise, widespread periods of VFR conditions are expected. Winds will be out of the southeast to southerly direction this afternoon before becoming light and variable overnight.
