SYNOPSIS

Warmer temperatures and dry weather will continue through next week.

DISCUSSION

High pressure will build across the region today, remaining over the Desert Southwest through the weekend and into next week. With that we will see warming temperatures with highs rising to 10-20 degrees above normal. The warmth looks to peak between Saturday through Tuesday before the ridge starts to shift to the east and allowing a slight cool down to occur (but still remaining above normal).

A weak shortwave looks to pass through on Saturday, clipping the northeastern part of the state. Moisture is very limited so not expecting much in the way of precipitation. Perhaps a few sprinkles may reach the ground, but otherwise it will remain too dry at the surface and remain virga.

Winds will generally be out of the west to northwest through Saturday and around 10-20 mph. This wave moving through on Saturday will briefly tighten the pressure gradient so we may see some slightly breezier winds, perhaps a few gusts around 25-30 mph, through the afternoon.

As we head towards mid week, the ridge shifts to the east as a weak wave passes to the west. Winds will be more southerly through midweek with some additional moisture being advected into the area. An isolated chance for a high-based shower or thunderstorm may occur, mainly Tuesday onward across the higher terrain.
