We’re finally getting some moisture...
Partly to mostly cloudy all week, with at least a slight chance of rain or snow flurries each day. The best chance for accumulating rain will be Friday – Saturday, possibly changing to snow, with 1”-3” of snow accumulation Saturday to Sunday. Breezy Tuesday – Wednesday and again Friday to Sunday. Highs generally in the upper 40s to mid 50s, cooling into the lower 40s by Sunday. Lows in the upper 20s to 30s.

An upper-level low will cut off from the jet stream on Tuesday and stall just west of the northern Baja of California. It will direct moist flow across Arizona for the next few days and produce considerable clouds and scattered light rain or wet snow showers, but the accumulations will be light, as lifting over northern Arizona will be minimal. The low will lift back northward amid the Jetstream and propagate eastward across southern Arizona on Thursday in advance of a colder and deeper upper-level trough on tap for this coming weekend. This second trough will produce stronger lifting and lower snow levels, with possibly accumulating rain on Friday to Saturday, changing to snow Saturday evening to Sunday. Long-range forecasts are indicating a third storm next Monday – Tuesday that could bring additional rain or snow accumulation. Here’s hoping and praying we receive some much needed precipitation and a little bit of drought relief! I expect an average of over an inch of liquid water equivalent to accumulate across the Prescott area by next Tuesday.
