— Flooding is NOT expected today
This morning’s weather setup is very similar to Wednesday’s with Colorado being positioned just to the south of a seasonably strong early summer jet stream. In this case, the jet stream is not only separating warmer air to south from colder air to the north, but is also acting as a moisture boundary. Areas to its south are very dry this morning, as seen in the low-level water vapor imagery below from GOES-16. Note that the black colors in NM, AZ and CA are actually off the color scale because of just how dry it is. This morning’s precipitable water (PW) in Flagstaff, AZ was a mere 0.1 inch.
Closer to home, PW values are more in the 0.25 to 0.5 inch range across the state, which is still much below seasonal normal. With plenty of sunshine this morning, expect a quick warm up with some fair weather cumulus clouds likely this afternoon. Areas towards the KS border could see an isolated shower or weak storm, much like Wednesday afternoon. However, nothing that warrants a flood threat.
