Through Wednesday, calm weather is predicted before a passing weather system brings increasing winds and rain chances, as well as colder temperatures, to the area Thursday and Friday, according to the forecast.
Temperatures will quickly climb back up to near or above seasonal averages this weekend and into early next week, thanks to high pressure building in from the west.
This will place the area on the western edge of a synoptic scale trough that is now affecting most of the continental United States. Despite the fact that temperatures are still several degrees below average and sky are generally clear, today and tomorrow will be rather calm.
Breezes will increase up a little on Wednesday, with brisk west southwest winds in the late afternoon and early evening.
During midweek, the next shortwave will migrate southward over the Pacific Northwest and Great Basin, passing through the local region Thursday night and into early Friday morning.
Precipitation is expected to begin Thursday evening and continue until early Friday morning, according to the forecast. With the arrival of this storm late Thursday night, snow levels decrease swiftly, hitting valley bottoms by early the next morning.
However, if the precipitation clears out before the colder air mass has a chance to settle in, the odds of that happening are reduced.
There is low to moderate confidence in these facts because of the unpredictability in the timing of this system, which should become clearer over the following 24 hours. The most visible effect will be felt on Thursday as a result of the winds, which will grow in strength out of the west southwest throughout the afternoon.
Blowing dust issues, as well as isolated critical fire conditions, are once again a possibility, mainly in Cochise County, Arizona.
On Friday, cooler air will begin to flow in, lowering the minimum and maximum temperatures by several degrees compared to Thursday.
Temperatures will swiftly rebound, though, as a ridge of high pressure rises in over the weekend. It is expected that high temperatures will return to normal by Saturday, and that they will rise a few degrees above usual on Sunday and Monday.
