Same book different chapter. The long stretch of hot and humid weather will continue into the upcoming weekend. Ridging will break down over the southwest U.S over the weekend allowing for zonal flow aloft. At the surface we will see an increase in southerly flow, leading to increasing moisture levels and with the high moving shifting over the area this weekend, temps will come up into the mid and upper 90s. With the increase in moisture we COULD see a few isolated showers and thunderstorms that will be diurnally driven, but with the jet stream displaced to the north, the trough well to the east and the high overhead, no major disturbance is expected to move through. Have lowered rain chances accordingly to account for this. With The somewhat drier air in place, heat index values will average near 100 each afternoon.
Monday through Thursday will be more of the same around the natural state. Sunny and hot days with warm and muggy nights. Zonal flow will remain in place for the period with the high pressure shifting back and forth through the region. A stalled front will remain in place north of the state. Hot and dry for most of us during the period but have included a couple of days with rain chances to account for diurnal heating creating enough lift for those typical afternoon showers and thunderstorms. Temps will remain at to above normal for late August..
