The monsoon is starving! The pesky high pressure center which briefly vacationed to the Gulf Coast earlier this week has shifted westward again. It now has two clear lobes...one across southwest New Mexico and another more problematic one off the coast of Baja California. In Colorado, we remain in-between this high and weak but broad troughing in the center of the country. …

A litter of shortwaves As promised, high pressure has pushed further south and east and is located across southeastern New Mexico this morning. Loosing some influence from this ridge, the central Rockies have become littered with mid-level shortwaves. As many as four mini-disturbances will be helping to enhance shower and storm activity later today, one of which is forecast to …

Drier Tuesday The "Four Corners" high pressure remains in-control for one more day. Models are consistent in showing that this high will weaken and slowly migrate eastward over the next couple of days. This transition will bring better chance of storms the rest of the week as southerly flow helps to advect in better monsoonal moisture. For today, though, slightly drier air …
