ARKLATEX (KSLA) - Summer's grip on the ArkLaTex is about to get even tighter. Yes, it's about to get even hotter.
By the end of the work week, an upper-level ridge or an area of high pressure be anchored over the ArkLaTex. With the ridge over head, strong subsidence or sinking motion of the air in the atmosphere will lead to hot temperatures and sizzling sunshine.
In the summer, high pressure should be represented by a big red H instead of big blue one.
The only way to beat the heat over the next couple of days will be to jump in the pool or stay inside. Afternoon highs for the rest of the work week and through the weekend will be in the mid to upper 90s.
We are not going to get any help from the humidity either. The Muggy Meter below shows sticky to oppressive conditions through next week, so that means the air is going to be very humid. Dew point temperatures will likely be in the low to mid 70s.
With highs in the mid to upper 90s and dew points in the low to mid 70s, max heat indices will be well above 100 degrees and could hit 105 degrees or higher each afternoon. With heat indices that high, you need to make sure to take some extra precautions to beat the heat, especially if you're going to work or spend a lot of time outside.
Most will not be cooled off by rain anytime soon. The latest run of FutureTrack shows most places won't even see a drop of rain through the upcoming weekend.
A complex of showers and storms will develop north of the ArkLaTex late Tuesday through Tuesday night and drop to the southeast. This complex might get close enough to the ArkLaTex to throw a shower or storm our way late tonight or first thing Wednesday morning. However, the better rain chances will remain north of the area. Only places along and north of I-30 will have a chance of rain.
Most will probably have to wait until next week before they see any rain. However, it's probably not going to be substantial.
From this distance, it looks like places along and south of I-20 will have the best chance of early next week.
With the heat and lack of rainfall over the next 7 days, drought conditions will continue to worsen and expand across the area.
