Forecast Discussion:

Moisture has certainly increased in Phoenix this morning, with dewpoint values in the low 60s°F. However, the weather pattern over the Southwest is not ideal for thunderstorms making their way into the Valley. This week, a wave of low pressure will prevent the monsoonal high pressure from setting up where it needs to be to give Phoenix decent thunderstorm chances.

Weather-wise, Phoenix will continue to see hot temperatures--above 110°F-- today and Tuesday. Highs are then forecast to fall back below the 110°F mark by Wednesday. Moreover, winds near the ground look to be somewhat breezy Tuesday and Wednesday: at least 10-15 mph with higher gusts out of the west-southwest. Otherwise, winds are expected to be light.

In regards to dust, the dust risk is Low each day since the potential for thunderstorm outflow winds impacting the Valley with dust looks low. However, we'll keep monitoring this potential, as things can often change in the monsoon season.
