Another large storm, currently in Oregon, will move south along the West Coast through Saturday, keeping warm and relatively dry air over our area with breezy to windy southwest winds for Saturday.
The storm will first move eastward into the Great Basin tomorrow before lifting to the northeast through Idaho on Sunday, brushing our area with a cold front with gusty winds Sunday afternoon. Models keep the airmass relatively dry, and have trended any Sunday afternoon storm weaker, or even non-existent in some models.
Following quickly on Monday, another Pacific storm approaches the northwest coast, allowing cool air from western Canada to spread over the western third of the US. The storm is further off the coast than the previous storm and allows some dry air from the southwest to be transported over Colorado for Monday and Tuesday, and possibly Wednesday. There will still be a chance of afternoon storms for each day, though, as numerous waves of energy travel over our area.
After traveling south along the West Coast on Monday, this storm is forecast to turn eastward around midweek and travel across southern Arizona and New Mexico, bringing increasing chances of cool and mostly showery weather for Thursday and Friday.
If you’ve made it this far, I am traveling this upcoming week and will likely be unable to publish forecasts prepared on Saturday, May 21 and Sunday, May 29. Also, the daily forecast might become more periodic next week, likely being refreshed every second or third day.
