Silas_Sancona Posted February 28 Report Share Posted February 28 A nice last day of winter on deck today.. One storm, and two cool nights ahead ..before what looks to be a nice stretch of weather ahead.. At least by the current forecast. Some other weather thoughts have a couple more storms in the cards for the area beyond next weekend. We'll see what happens.. As winter ends, a quick comparison between this and last winter here.. ( ** Via Accuweather past temp data for Chandler, AZ ) Dec: 22 **Unable to retrieve data ( from Accuweather ) for Dec. '21. Needless to say, December of 2021 started off hot / above normal, then trended below normal near/after X-mas. Lows below 35F : 3 ^Lows below 30F: 0 Highs below 55F: 3 Highs above 75F: 0 Dec. 22 Lowest, 30F Jan: '22 '23 Lows below 35F : 2 *8 ^ Lows below 30F: 0 0 Highs below 55: 1 *4 Highs above 75F: 0 0 Jan. 23 Lowest, 30F. Jan. '23 most below 55 and 35 readings recorded. Feb: '22 '23 Lows 35F and lower: *5 1 ^ Lows Below 30F: 0 0 Highs 55 and lower: *4 2 Highs above 75F : *10 1 Highs 90F+ 0 0 Feb. 23 Lowest, 30F. Feb. '22 most below 55 and 35 readings. Feb. '22 = Highest total of 75F+ readings recorded. ^ = What whatever station Accuweather uses recorded. Various neighborhood stations via WX Underground saw lower readings during the same events each month, so yes, some parts of town did drop below 30F at least once or twice per month this winter. *= Highest total of X readings recorded each month per winter season. As spring starts, some stuff to watch as we head for some March Madness.. For the moment, like where things may be headed, but not putting a stamp of approval on any forecast for now.. ***Photo / Info Credit: Spot On Weather *** ECMWF forecasts: GEFS Forecasts: In a nutshell: The "idea" of an overall pattern shift to a cooler East / milder ..or warmer.. West occurring over the next couple weeks appears to have some teeth.. For the moment anyway.. Doesn't mean we'll see an early start to nothing but upper 80s / 90s, or that it will Snow in Florida, though " False Spring " may get a hard kick to the N**s in some areas back there soon. For the West, If it does trend back toward positive, would like to see the PNA higher than +1 for a change to sustained, and widespread above normal temperatures. ***Since it is seldom discussed, a simplified idea of what both the EPO ( Eastern Pacific Oscillation ) and WPO ( Western Pacific Oscillation ) phases ( in winter ) mean, ...for the Southwest / CA specifically.. Both Teleconnections influence rainfall / our wonderful "Nuke Fests" during the summer as well. *** Keep in mind, these are " general " ideas on what effects each can have on the weather during a particular phase. Obviously, other teleconnections in the atmosphere can amplify or dampen the influence of each / both at any given time. *** EPO Phases ( In Winter / Spring ) Positive: Cool / Cold and Dry Negative: Warm / Wet WPO Phases: Positive: Warm / Dry Negative: Cool / Cold / Wet Link to comment Share on other sites More sharing options...
