Synopsis:
We’re in the midst of another well publicized heat wave that will extend at least through the end of this week. Excessive heat warnings are in effect through Sunday for the entire region. Please take necessary precautions in order to avoid heat related illness. In other news, modest moisture return into AZ has led to an uptick in clouds and may allow for a few showers/t-storms across our region later today, though the focus will remain to our south and across the higher terrain areas north/east of Phoenix. Moving ahead, drier conditions are expected into Saturday with high pressure overhead, before the ridge settles into the Great Basing region Sunday into next week. This positioning is historically favorable for increased Monsoon storm activity moving off the higher terrain areas into the lower deserts. The only caveat is whether we’ll have enough moisture in place to take advantage. We’ll have more details on this in the coming days.

For today plan on sunnier conditions later morning/into the afternoon. Daytime temperatures will quickly warm back into the 112°F-114°F range around the Valley. South/southwest winds will hover in the 5-10mph range with localized greater gusts possible into this evening. Storm activity will generally remain across the higher terrain areas north and east of the Valley and across southern AZ, but we could also see a few evening showers/storms pop up over the lower deserts if we get the help of outflow boundaries.

Tomorrow looks to be the warmest day of the week. Afternoon temperatures will max out in the 113°F-116°F range around the Valley under mainly sunny skies. Variable winds will generally stay below 10mph with no gusts of any consequence throughout the day. No storm activity expected around the region tomorrow. Hot temperatures will continue over the upcoming weekend. Highs are expected to reach around the 114°F mark both days. As mentioned above, the pattern will start to look a little more interesting for storms by Sunday and as we move into next week especially if we can draw deeper moisture back into the state.
