SYNOPSIS

Mostly dry and mild conditions expected through the weekend, with a slight chance of showers across eastern Arizona. Unsettled and cooler weather looks to return early next week.

DISCUSSION

A low will pass well to our south this evening, which will keep us dry. There may be a few isolated showers that find their way near the White Mountains but for the most part expect the dry conditions to continue.

A weak shortwave will cross through northern and northeast Arizona on Friday, gradually pushing into New Mexico on Saturday. This wave will allow temperatures to become slightly cooler and with limited moisture only some isolated showers may occur late Friday and Saturday. Any shower activity looks to be confined to Apache County and mainly across the higher terrain. Dry air will then quickly move into the region with everywhere drying out by Saturday evening.

A weak ridge will then move across the region on Sunday as a closed Pacific low starts to move into southern California. The gradient will tighten up and we will start to see an increase in south- southwest winds on Sunday and Monday. Additionally, the southerly flow will be able to tap into a better moisture pool, which may help bring more showers to the region on Sunday. Models seem to agree that the low will flatten a bit on Monday before deepening and pushing inland and across Arizona. The details are still a bit muddled this far out but the weather looks to be cooling off and remaining unsettled through the middle of the week.
