Are You Ready for Snow? National Weather Service

Looks like our parched ground will get some moisture!


Big Idea

  • Back-to-back storms are coming
  • Starting with rain, changing to snow
  • One this weekend, and one on Monday-Tuesday
  • It’s going to be really cold, too
  •


Winter has arrived!


Forecast Update:


Back-to-back storms are on tap starting tomorrow. Expect rain showers changing to accumulating snow across the Prescott area this weekend and again next Monday - Tuesday. The long-range forecasts are indicating still another storm system next weekend (yet long-range forecasts remain very uncertain). Bottom line is that there is good confidence in a forecast of heavy snowfall and increasingly cold temperatures Sunday through Tuesday. Below is the latest briefing information from the NWS:



Expect an extended period of Winter Weather Conditions from Friday through Tuesday. The focus of this five day period will be two storms, the first expected Saturday and Sunday, the second expected Monday and Tuesday.


There will be a period of more showery weather ahead of the first storm on Friday, with a brief period of more showery weather between the storms Sunday night. Snow levels will fall steadily with each storm, reaching 4000 feet by Sunday and as low as 2000 feet by Tuesday morning. This means larger areas for medium to high impacts, especially with the event on Monday and Tuesday.


Key Points:

  • Two winter storms will impact the area over the next several days.
  • The first storm arrives Saturday, lasting into Sunday. Expect medium impacts due to snow, mainly over the higher terrain.
  • The second storm arrives Monday, lasting into Tuesday. Expect medium to high impacts over a larger area. Light snow accumulations are possible by Monday night down to our lowest elevations, with heavy snowfall possible above 5000 feet.
  • Bitter cold temperatures Wednesday and Thursday morning. Low temperatures ranging from the single digits to lower teens above 4000 feet.


The latest location-specific snow forecasts are below.
