All good things, such as springlike weather in January, must come to an end. A storm is expected to drop temperatures and showers across Arizona, beginning late Wednesday.
In the Valley, the forecast precipitation totals are in the range of two-tenths of an inch and lower, the National Weather Service said. The higher elevations could see a half-inch by the time the storm departs early Friday.
Because this low-pressure system will be tapping moisture from the warm tropics, snow levels should remain fairly high: 9,000 feet on Wednesday night, falling to 8,000 feet by Friday.
Thursday is expected to be the most active day for precipitation.
Daytime highs at the end of the work week should drop into the low 70s, which still is slightly above normal for this time of year.
For more than a week, temperatures have been hovering at a level more suitable for late March. Today's official high for the Valley was 80 degrees; it marked the first time in 2009 the mercury reached that level. That reading was 12 degrees warmer than normal, but four short of the record set in 1950.
Wednesday's forecast high is 79, which would tie the record high for the date.
