ARKLATEX (KSLA) - Some parts of the ArkLaTex will have to deal with two types of extreme weather on Friday: severe storms and dangerous heat.

A SEVERE THUNDERSTORM WATCH has already been issued for parts of NW LA and SW AR. The Severe Thunderstorm Watch is in effect until 7PM.

Even if your parish or county is not under the Severe Thunderstorm Watch, you still need to keep a close eye on the sky. The latest severe weather outlook from the Storm Prediction Center has most of the area still under a Slight or Marginal Risk of severe weather this afternoon.

The main threats with the strongest storms that develop this afternoon will be large hail and damaging winds. However, the tornado threat is not zero. Heavy rain and frequent lightning will be secondary concerns.

Overall, our storm chances are not very high on Friday, so not everyone will see rain. The best chance of storms will coincide with the greatest threat of severe weather. Parts of SW AR and NW LA will have the best storm chances this afternoon and evening. However, showers and storms could develop further west this afternoon.

By 4 p.m. on Friday, the latest run of FutureTrack shows strong storms dropping to the southeast across parts of NW LA. Keep in mind, a few of these storms could produce damaging wind gusts and hail.

The threat of strong to severe storms should be winding down around 8 p.m. The latest run of FutureTrack shows the strongest storms southeast of the ArkLaTex by 8 p.m.

The heat and humidity will be fuel for the storms that develop this afternoon. However, many will not see any rain or storms this afternoon. Many will just have to worry about beating the heat. With afternoon highs in the low to mid 90s and dew points near or above 70 degrees, max heat indices will be close to 105 degrees in some locations. With heat index values that high, we need make sure to take it easy outside this afternoon and stay hydrated.

On Saturday, the greatest threat of severe weather will lift north of the ArkLaTex. However, a strong to severe storm can't be ruled out across the northern edge of the ArkLaTex, mainly along and north of the I-30 corridor.

The latest run of FutureTrack shows a cluster of showers and storms developing across Oklahoma and impacting the I-30 corridor late tonight or first thing Saturday morning.

By 4 p.m. Saturday, the better storm chances will be just north of the ArkLaTex. However, a storm or two could develop far enough south to impacts parts of SE OK and SW AR.

By midnight on Sunday, the better storm chances will still be north of the ArkLaTex. However, once again, a storm or two could impacts places along and north of the I-30 corridor Saturday night through Sunday morning.

With the all the heat and humidity around, a few pop-up showers and storms will be possible Sunday afternoon. At this time, strong to severe storms are not expected at this time.

The main weather headline for many this weekend will not be storm chances but the heat. Max heat indices in some spots could approach 105 degrees on Saturday and Sunday, so make sure you and your family beat the heat. You probably don't want to over do it outside this weekend and make sure to stay hydrated.

The KSLA First Alert Weather Team will keep you updated on the severe weather risk. Here's how you can stay weather aware:
