Your Saturday Forecast – Ridge Shifts West Next Week

Another day of widespread 100 degree highs across the state today, then we begin to see highs drop back to more seasonal levels as our current ridge of high pressure and its heat dome begins to drift west. This will also bring better rain chances into the state throughout the week as the ridge remains centered over the desert southwest through most of next week. Today, most of the state will remain dry, but we will see some slight to 20% chances for seeing scattered showers develop this afternoon across far east and southeast Texas coastal zones. Nothing too severe with any of these spotty showers…just the general threats of lightning and brief heavy downpours to be aware of if you’re out and about this afternoon across this portion of the state.

Highs today…sweltering once again with widespread 100 degree readings across the state. Lower humidity levels will keep heat index readings closer to the actual temperatures for areas west of the I-35 corridor. However, widespread heat index readings between 105 up to 110 will be felt across areas east of the I-35 corridor towards the Texas/Louisiana border. Heat Advisories remain in place through 7pm this evening for several counties across far east and northeast Texas. After today, we should see the need for these heat advisories diminish as the high pressure ridge shifts west and we begin to see the cool(er) effects of more easterly flow across the region.

A Look Ahead – Chances for more widespread rainfall increase Monday and Tuesday as the center of the high pressure ridge settles in over the desert southwest and opens the door for the approach of a weak upper level disturbance from the east. Unfortunately, not everyone will see rain, with the best chances remaining across the eastern half of the state. After Wednesday, with the high pressure ridge still centered well west of the state, the northern half of the state will likely see the return of northwest flow in the upper levels. This pattern tends to increase the chance of seeing nocturnal convection in form of squall lines that move south out of Oklahoma during the late evening and continue overnight into the early morning hours. Not a lot of confidence in that scenario just yet, but it will be worth watching as we get into the latter part of our next work week.
