aslkahuna Posted July 4, 2011 Share Posted July 4, 2011 Easterly flow has become established and dewpoints have soared into the upper 50's to mid 60"s with boomer activity becoming more widespread. These are all indications ofn the natural establishment of the Summer monsoon over SE AZ. Based upon current data and assuming this isn't a false start, monsoon start date will be July 2nd for Sierra Vista and most likely July 3rd here. eve Link to comment Share on other sites More sharing options...

Ed Lizard Posted July 5, 2011 Share Posted July 5, 2011 SPC "See Text" ...AZ... A MONSOON-INDUCED MOIST AIRMASS WILL PERSIST ACROSS AZ INTO WEDNESDAY. WHILE CONSEQUENTIAL LARGE SCALE FORCING AND THE EXACT DEGREE OF STEERING FLOW ARE UNCERTAIN IN VICINITY OF THE UPPER RIDGE...IT SEEMS PROBABLE THAT A FEW STORMS WILL BE CAPABLE OF DOWNBURSTS WEDNESDAY AFTERNOON/EARLY EVENING ACROSS SOUTHERN AZ/PERHAPS ADJACENT LOWER CO RIVER VALLEY.

aslkahuna Posted July 5, 2011 Author Share Posted July 5, 2011 After last night's working over by a Black Wall of Doom which brough severe weather to the downtown area, most of Tucson will be quiet today. Visually boomers are all around us but we're in a large clear area. Big mamu down to the SSW. Last night's IR imagery was classic monsoon.

trjacob1 Posted July 6, 2011 Share Posted July 6, 2011 The dust storm was cool but I was really looking forward to seeing some severe thunderstorms here in Phoenix. Tucson is having a really good start to the monsoon season with 1.51 inches of rain falling during the past two days. Link to comment Share on other sites More sharing options...

aslkahuna Posted July 6, 2011 Author Share Posted July 6, 2011 This was a surprising event since we usually don't get two storms like this in a row but the dynamics associated with a monsoon disturbance triggered and extremely severe thunder stom east of Tucson. The clear skies of TUS in the afternoon was a result of the inflow into the developing storm 40 miles away. A small thunderstom ahead of the line segment reversed course and was drawn into the big storm with radar showing the smaller storm being ripped apart by the intense inflow in the mid levels. Sustained winds of 62 mph with gusts to 77 mph hit D-M, the airport has gusts to 71 mph and the UofA 81 mph with widespread damage the gust front consolidated near Casa Grande and that's where the haboob developed. Monday's storm was microbursty and was an appetizer while yesterday was a massive gust front and the main course. Dessert today? hard to say.

Msalgado Posted August 3, 2011 Share Posted August 3, 2011 Most productive? Not for NM. We're still incredibly dry even with the past few weeks of spotty rains. ABQ had the 17th driest July on record. After the next few days models show a dry pattern taking hold once again, as well. Link to comment Share on other sites More sharing options...

Reed Stough Posted August 4, 2011 Share Posted August 4, 2011 Last night we went storm chasing in PHX We intercepted two cells travelling north on the 101 - the strongest of the two was located around Princess Dr. and the 101. On the way south to Tempe, we stopped at Indian Bend and 101 and there were at least 70+mph winds. The 5 and Diner across from where we were lost most of their outdoor tables and unbrellas into the parking lot. Finally, on the way home we got hit again. It was a great night with LOTS of lightning.

aslkahuna Posted August 5, 2011 Author Share Posted August 5, 2011 Other than those two good storms on 4-5 July, the monsoon in Tucson has been crap and not worth talking about. Steve Link to comment Share on other sites More sharing options...
