Gusty winds are expected to target most of the state on Tuesday at the same time snow will be falling in Denver. Who will see what intensity, read on for and view the model within for details …
A cold front is expected to move through Wyoming and Colorado on Tuesday, where I have issued over my national page the Winter Storm Watch (Click here to read that). The cold-air in the Great Basin as a result will create a thermal gradient with the hotter air in Arizona. This will bring winds through the Las Vegas and Utah areas early Tuesday and eventually jet out into below the passes and canyon south and west of the mountains.
Level 5 intensity will be seen along the Rim and Colorado River Valley, according to my wind model. Values of intensity 6 and isolated 7 will surround the Bullhead City area so those of you there should prepare for this wind event.
As shown in the model below, the Phoenix and Tucson Metro areas are in the level 3-4 zones, which isn’t too strong, but it will be noticeable. The model below is the AZWF Wind Gust Model and the intensity values included.
