UPCOMING RAINFALL TO HELP THE PERSISTENT DROUGHT IN THE DESERT SOUTHWEST! (credit: NWS Phoenix, Arizona)
DISCUSSION: As a drought continues to linger across much of the Southwestern United States, there may be some minor relief heading to that part of the country later this week! This looped satellite imagery clearly depicts a low-pressure system beginning to develop well to the southwest of Southwestern U.S. at this time. As this low-pressure system begins to track towards the continental U.S. the potential for measurable rainfall will increase; helping to alleviate more of the ongoing drought situation plaguing that part of the country for quite a long time-running. It is likely that as this moisture begins to track further inland, the higher-terrain across parts of Southern California, Arizona, and New Mexico will help to generated locally heavier rainfall via the enhanced lifting of moisture-laden air-streams over elevated topography (a.k.a. orographic lifting).
