Dangerous heat this weekend

By Grant Dade - bio | email |blog

EAST TEXAS (KLTV) - The run of cooler than normal temperatures and afternoon showers and storms is about to come to an end. A strong ridge of high pressure will move into the area and this will dry out the atmosphere and allow temperatures to soar to the upper 90s to near 100 degrees. We will still have a slight chance of a shower or two this afternoon however, most areas look to stay dry.

The heat really begins to build this weekend. Temperatures Saturday and Sunday will warm to around 100 degrees with heat index values surpassing 105 degrees. The rainfall we had this week will help keep us a few degrees cooler than we could be. The sun's energy will be use to evaporate soil moisture rather than heating the Earth's surface helping to keep us around 100. If enough soil moisture is evaporated Friday and Saturday, Sunday and Monday could be very hot. Raw forecast data is putting our actual air temperatures around 102 to 105 degrees which would put our heat index close to 110 degrees. So we will have to watch our temperature trends very closely over the next few days.
