and dry weather return by Sunday, with much warmer temperatures.

.PREV DISCUSSION /449 PM MST/...Low pressure was centered over
south central Arizona this afternoon, heading toward the east.
Scattered to numerous showers have developed with daytime heating,
most widespread in the White Mountains region closer to the low.
Snow levels are around 5500-6000 feet but most of this is melting
as it falls, except above around 7000 feet. By mid evening, most
of the shower activity will diminish. The exception looks like the
White Mountains area where moist upslope flow from the north
should keep showers going overnight in some spots. By Saturday,
the low will move east into New Mexico, though moist and cool
northerly flow in eastern Arizona (Navajo and Apache counties)
will keep daytime shower chances in the 40-60% range. Chances
decrease as you head westward, with a 20% chance for Flagstaff,
Sedona, and Prescott. North-northeasterly flow will increase early
Saturday morning, producing breezy conditions especially for
Coconino and Yavapai counties. Expect sustained winds of 15-20 mph
in this area, with some gusts to around 35 mph in the favored
downslope/gap locations. Winds should start to decrease by
afternoon.

Sunday through next week - Low pressure moves well east of the
state with high pressure gradually building over the southwest US.
This will result in dry weather, light west to southwest breezes
of 10-15 mph, and much warmer temperatures - especially Tuesday
through Friday. By mid to late week, daytime highs are forecast to
be around 15 degrees above normal. These values will be within a
couple degrees of reaching daily records in some locations.
