I’m RV’ing through parts of New Mexico, Arizona, Utah and Wyoming this Thursday – Saturday, 28-30 April. Some updates and responses may be delayed due to limited communications!
A series of storms moving west to east, all bringing a combination of high elevation snows, heavy rains, severe thunderstorms and strong winds.
Extended outlooks are more general in nature than the daily short term forecasts. Beyond a week, there is often significant uncertainty in the location and intensity of specific weather events. I will note where there is less, or greater, confidence than normal in these extended outlooks.
