Odds Favor Wetter than Normal July as Monsoon Season Looms

———-

The Climate Prediction Center recently released their latest monthly temperature and precipitation outlooks for July 2018. Odds are favoring wetter than normal conditions developing across much of the southwestern United States, especially in the Four Corners area. The wet conditions look to continue through September as the CPC’s three month outlook (including the months of July, August and September) shows odds favoring above normal precipitation. As far as temperatures are concerned, odds favor warmer than normal temperatures across Utah and into far western Colorado for July with above normal temperatures favored across the entire western United States through September.

What is the Monsoon?

The North American Monsoon Season typically begins towards the end of July and continues through early September. It is associated with a long duration weather pattern shift as the subtropical ridge of high pressure amplifies and moves to our east. This results in a shift in upper level winds with the flow turning to the south, allowing for moisture to be pulled northward from the Pacific Ocean and the Gulf of Mexico.
