SYNOPSIS

Gradually warming temperatures and dry conditions are in store for much of the week and into the weekend, along with typical afternoon breezes.

DISCUSSION

Aside from weak troughing over the west, quasi- zonal flow largely remains in control through much of this week. Gradually warming temperatures and dry conditions are expected through at least at least Saturday as a result. Winds look to generally remain light, however the aforementioned troughing will keep some typical spring- time afternoon breezes (20-30 mph) over the higher terrain.

A weak low looks to eject off the Pacific into the southwest early next week. Ensemble guidance continues to signal towards an increase in PWATs from the resulting increase in moisture advection into Arizona. As of now, a few isolated afternoon showers and possibly thunderstorms look probable over the White Mountains this weekend, then potentially spreading to more of the higher terrain for Monday and Tuesday. However, surface moisture at this point still looks fairly minimal, so much of the activity at this time looks to be high-based in nature.
