As expected the expanding region of high pressure across the ArkLaTex has resulted in temperatures at or above 100 degrees in many areas. We have already tied the record high of 104 degrees in Shreveport. Highs will be in the 102 to 105 degree range through Sunday, with a cool down expected by the middle of next week.
Tonight we will see a little relief after sunset as lows will fall into the mid and upper 70s under mostly clear skies.
The warm up will be fast again on Friday. AN EXCESSIVE HEAT WARNING will be in effect from 11 a.m. until 8 p.m. Heat index values will be near 110 degrees. It will be mostly sunny throughout the day. There will be a southwest breeze of 10 miles per hour, which may provide only a little relief if you have to be outside.
The center of the ridge of high pressure will be closest to us Saturday, so I think we’ll see quite a few areas at or above 104, in what might turn into the hottest day of this stretch. The ridge will begin to retreat westward late in the weekend and open us up to returning rain chances by next Tuesday. Scattered showers and storms will be possible during the middle of the week, cooling highs to near normal levels in the mid 90s.
