Discussion:
Skies were mostly sunny throughout the day with only a small amount of isolated storm activity in the eastern and southeastern portion of the state today (July 5th) as the flow pattern over the state within the past 24 hours has shifted westerly, resulting in large amount of drying. High temperatures today were above normal by several degrees due to building high pressure and dryer conditions.

For Monday, the heat will continue with a ridge of high pressure centered over the state, as a result of a trough moving into the northwestern United States. This will result in a continued dry westerly flow across the state leaving only the extreme eastern and southeastern portion of the state with enough moisture for at least a slight chance of thunderstorms. For the valley, skies should be mostly sunny with temps about the same or a degree higher compared to what was seen on Sunday.

Much of the same on Tuesday as high pressure aloft shifts slightly to the southwest and is centered just off the coast of southern California by the afternoon/evening hours, resulting in continued dry conditions for the valley and only a slight chance of storms once again in extreme eastern and southeastern Arizona. With the high shifting slightly southwestward, high temperatures may be down a degree of two compared to Monday, but mostly sunny skies will continue.

Wednesday will be the beginning of a transition from the dry westerly conditions, to a more southerly to southeasterly moist flow. This is due to the area of high pressure centered over southern CA in the morning shifting eastward throughout the day and by the evening hours being centered along the Arizona/New Mexico border, resulting in a more moist southerly to southeasterly flow once again becoming established across the state. With this, the moisture content will likely start to increase, but not expecting any thunderstorms across the valley as the atmosphere will take some time to moisten, but the shift is promising for a nice insurgence of moisture back into the region for later in the week. High temperatures will likely be about the same as was seen on Tuesday with some high clouds possible in the afternoon and evening hours.
