510 FXUS65 KABQ 182324 AAA AFDABQ Area Forecast Discussion...UPDATED National Weather Service Albuquerque NM 524 PM MDT Wed Sep 18 2024 ...New AVIATION... .SYNOPSIS... Issued at 230 PM MDT Wed Sep 18 2024 Drier and warm Thursday ahead of the next storm system with some breezy southwest winds across the western and northeast highlands. Shower and storm chances return along and east of the central mountain chain Friday and Saturday as the system moves through the far northern parts of the forecast area. A few storms could become strong to severe. Western and central areas will generally be dry and breezy with cooler temperatures Saturday behind the cold front. Dry and mild areawide Sunday and Monday behind the storm. Low forecast confidence for the middle of next week. && .SHORT TERM... (This evening through Thursday night) Issued at 230 PM MDT Wed Sep 18 2024 Splendid weather conditions today have provided a welcome break from the active pattern of late. A large dry intrusion sliding over the region today is allowing humidity levels to fall to between 20 and 30% with slight southwest breezes and seasonably mild temperatures over most of the area. Tonight will be similar to last night under clear skies and decreasing winds. There is a non-zero probability for a patch of low stratus to develop over the far southeast plains late tonight but confidence is also very low. Thursday will feature slightly stronger southwest winds as a 565dm H5 low center approaches from SoCal. A batch of cirrus is expected to slide north over the region with little impact other than a brief period of filtered sunshine. Temps will trend a few degrees warmer with southwest breezes in the 20 to 30 mph range. Humidity will trend even lower with many areas in the 10 to 20% by midday. Just enough moisture will return to southeast NM to allow a few high- based showers to develop with gusty winds around the Caprock. Thursday night will be similar to tonight but with slightly warmer temps, increasing cirrus, and deeper moisture advecting into the eastern plains. && .LONG TERM... (Friday through Tuesday) Issued at 230 PM MDT Wed Sep 18 2024 A 569 dam upper low will be over the southern CA during the day Friday and just south of Las Vegas, NV Friday evening along with a 592 dam upper high centered over the TX Big Bend. Increasing upper level divergence aloft ahead of the upper low combined with higher surface and mid level moisture along and east of the central mountain chain due to return flow on the western flank of the upper high will result in the development of scattered showers and storms across the central mountain chain moving northeast across the eastern plains later in the afternoon and evening. Instability does not look that impressive on Friday with some MLCAPE values around 750 J/kg across the northeast plains, according to the NAM. However with effective bulk shear values of 40 to 50 kts, storms will be capable of becoming strong to severe. Training cells Friday afternoon will result in a concern for flash flooding on the HPCC burn scar, but it looks like the heavier QPF sets up just east across the northeast highlands. Meanwhile, areas along and west of the central mountain chain will remain dry with breezy south and southwest winds across the middle and lower RGV and western highlands. Temperatures will be 5 to 10 degrees above seasonal averages. As the upper low moves northeast towards the Four Corners Friday night into Saturday morning, positive CVA and upper level divergence will help keep a chance for showers and storms across the northeast part of the state overnight. The upper low moves across the NM/CO border during the day Saturday. Some showers will be possible under the upper low due to some mid level moisture in the circulation, but much drier air will be surging north and east along the southern part of the upper low and behind the Pacific cold front. Temperatures cool by 5 to 10 degrees across western and central NM on Saturday behind the Pacific front with dry conditions and gusty west winds. The front along with positive CVA ahead of the upper low circulation will result in the development of more showers and storms across northeast and parts of east central NM midday Saturday with fast storm motion to the northeast. Showers and storms across northeast NM will be more capable of becoming strong to severe on Saturday due to high surface moisture, MLCAPE values as high as 2500 J/kg, and effective bulk shear values of 50 to 60 kts. Storms should exit north and east of NM during the mid evening hours. Drier air behind the system will allow temperature to efficiently cool for most Saturday night Sunday morning with mountain valley locations likely getting below freezing, mid 30s to near 40 across northern and western valley locations, 40s to near 50 in the middle and lower RGV and 50s to near 60 across eastern NM. Can`t rule out a few stray showers across far northeast NM as the upper low moves through. Sunday will be dry with slightly below average temperatures areawide with a backdoor front through all of eastern NM. A light to moderate east canyon wind could be possible in the ABQ Metro Sunday evening as the backdoor front tries to seep through the central mountain chain. Forecast uncertainty increases next week due to deterministic and ensemble guidance differing and flip flopping on the evolution of the next upper level trough diving south across the Rockies and Great Plains with a upper high over the Pacific coast. Return flow across eastern NM will bring back some modest moisture across that part of the state resulting in a chance for a shower or storm, but the upper level pattern could turn into either an Omega Block (ECMWF) or a Rex Block (GFS) over the western US and southern Rockies mid next week. Stay tuned! && .AVIATION... (00Z TAFS) Issued at 511 PM MDT Wed Sep 18 2024 VFR prevails through the TAF period. Prevailing southwesterly winds taper off this evening, returning at lesser speeds Thursday afternoon. && .FIRE WEATHER... Issued at 230 PM MDT Wed Sep 18 2024 There are no widespread critical fire weather conditions expected for the next 7 days. A strong storm system approaching from the west will spread breezy south to southwest winds across the region thru Friday. Western NM will see driest conditions with min RH falling to between 10 and 15% each afternoon. Eastern NM will be on the wetter side of the storm with increasing storm chances Friday and Saturday. Some of this activity may become strong to severe. Stronger west winds will spread over the rest of the area Saturday with cooler temps. A backdoor cold front entering eastern NM Sunday will keep temps cool across the east with breezy northerly winds. Forecast confidence into next week decreases considerably as model guidance is struggling with the weather pattern across the western U.S. && .PRELIMINARY POINT TEMPS/POPS...
