Silas_Sancona Posted September 25, 2019 Report Share Posted September 25, 2019 After one of the driest and hottest summers, both categories likely coming in within the top 10 this year, the first day.. and week of Autumn arrived yesterday quite dramatically across Arizona.. Thanks in part to a duo of dying tropical systems ( Lorena and Mario ) moving into a favorable position in/ around Baja Sur, and an anonymously strong, and early low pressure area that rode down the east side of the Sierras yesterday, and is currently anchored, but wobbling over Puerto Penasco ( what happens when one sips too much Patron silver, lol ) Arizona recorded not one but 3 Tornadoes. F-0 up near New River ( far north side of the Phoenix Metro ) an F-1 in Wilcox ( east of Tucson ) and a warned storm this morning down toward Sells ( way out in the middle of nowhere, due South of Casa Grande, near Ajo ) First time in 3 years the area NWS has issued Tornado Warnings. Valley saw multiple rounds of heavy rain / Flash flooding, strong storms ( meanest looking/ strongest storms last night were mainly the north / north east sides of the Valley). Heaviest rainfall, (amounts between 4-7") fell up in the Tonto Basin, north east of Mesa / Apache Junction,( to my north east. ) Large hail, and on top of all that, tops of the San Francisco Peaks in the shadow of Flagstaff were dusted with about an inch of Snow. Pretty crazy, and what a sudden change considering our dud of a Monsoon season, and relentless heat, due, in part, to the lack of rain this summer across most of the state( S.E. AZ was doing better than the rest of the state though ). Tucson and most of Southern / S. Eastern AZ got dumped on late last night / today. Dry most of the day today here but storms are re firing and headed north south of Ajo. Tomorrow's forecast could include more heavy rain / flooding, and strong storms as round 2 moves in, and might continue on/ off thru the morning hours of Thursday. Supposed to clear out and warm a bit Friday / over the weekend, ( only 90-92f at best though. Not bad for the end of September ) but, some hints of another possible wet spell later on. Hoping the focus of heavier rain tonight - Thursday Am is overhead.. Got some rain yesterday but nothing like the 1"+ amounts seen over a good chunk of the Valley, excluding the rain gauge at Sky Harbor.. Only received like .12" while areas a couple miles east or north saw 1-2" amounts.. Pretty crazy spread across such a short distance. San Diego / L.A. Basin?, don't be surprised if you also see some showers tomorrow / Thursday also. Same general pattern may usher in quite a good episode of early season Snow over the Northern Rockies, possibly into the N. Plains over the weekend / sometime next week. Same Trough settling into the Western States might drop our overnight lows into the low 60s / upper 50s across the Valley for acouple mornings.. Regardless, no more 100f highs forecast going forward.. looks like that's ended for the year. After a relatively silent, dry, and sizzling Summer, this week is my kind of way to kick off the fall.. Hopefully October brings more.. Welcome, to the start of Northern Hemisphere Autumn, 2019. 4 Link to comment Share on other sites More sharing options...
