193 FXUS65 KABQ 151143 AAA AFDABQ Area Forecast Discussion...UPDATED National Weather Service Albuquerque NM 543 AM MDT Wed May 15 2024 ...New AVIATION... .SYNOPSIS... Issued at 119 AM MDT Wed May 15 2024 Shower and thunderstorm chances increase this afternoon, mainly north of Interstate 40. Showers and thunderstorms continue into this evening and overnight thanks to a backdoor cold front sliding in from the northeast and east. Scattered to numerous showers and storms remain on track for much of the forecast area east of the Continental Divide. A few of the thunderstorms could become strong to severe over far northeast NM this afternoon and over east- central and southeast plains Thursday. Dry and much warmer weather is forecast Friday through next weekend. Sunday continues to look like the hottest day of the next week. && .SHORT TERM... (Today through Thursday) Issued at 119 AM MDT Wed May 15 2024 Convective initiation will begin around noon today along the east facing slopes of the high terrain of northern and western NM. Weak mid-level winds associated with an upper-low will favor slow storm motions over western NM so updrafts will go down as quickly as they come up. On the other hand, storms that drift off the east slopes of the Sangre de Cristo mtns will organize as they move down into the more moist and unstable environment in the northeast plains. Bulk shear of 30-40kts will be enough to organize storms as they approach the TX border. Initially, large hail will be the main threat, but wouldn`t be surprised if colliding cold pools end up creating storm clusters and shifting the severe threat more to damaging wind during the late afternoon/evening hours. Lowering cloud bases will allow for more efficient rainfall rates in the late afternoon and evening as well so flash flooding can also not be ruled out in the northeast if clusters of storms do end up developing. After sunset, all eyes turn to the central mtn chain where easterly upslope flow along the outflow aided backdoor cold front will lead to the development of widespread showers and storms. The current thinking is that precipitation rates will be on the lower side, limiting flash flooding potential over the HPCC burn scar. That being said, a solid 3-6 hours of light to moderate rainfall rates could end up producing upwards of 0.5" of rainfall overnight. The backdoor front will push through the gaps of the central mtn chain, but gusty east winds in Albuquerque appear unlikely. However, more robust convection over the central highlands during the evening hours could boost winds higher than currently forecast. Model guidance is in quite good agreement that a broad swath of precipitation will develop in central NM along a convergence zone where the backdoor front meets an upper-low crossing over the state. This cluster of showers and storms will intensify as it drifts eastward into the eastern plains during the afternoon hours Thursday. Strong vertical speed shear associated with the upper-low could organize these storms into a QCLS with both a large hail and damaging wind threat that will be maximized in the southeast plains. && .LONG TERM... (Thursday night through Tuesday) Issued at 119 AM MDT Wed May 15 2024 Lingering showers and thunderstorms will be moving off to the east of NM Thursday evening. A rapid warm up continues on track for Friday with temperatures forecast to warm 10 to as much as 20 degrees above Thursday`s high temperature readings. The warming trend continues through the weekend underneath high pressure aloft Saturday and increasing southwest flow aloft Sunday. Winds will likely increase somewhat into the breezy category Sunday beneath the increasing southwest flow aloft ahead of a southern stream closed low on approach into southern CA. GFS and ECMWF are now in better agreement with regard to Sunday night and Monday. Both models now have the northern stream (Asian Pacific or polar jet stream) kicking out the closed southern stream (subtropical jet) low over NM on Monday. Windy conditions result areawide for much of the day Monday into Monday evening. A slightly cooler airmass is forecast to move in behind the associated surface cold front Tuesday, mainly east. Global models remain in good agreement for Wednesday through the latter half of next week with dry southwest flow aloft over NM keeping the dryline east of the state. In other news, weather prediction models are now showing the first signs of the strong subsidence or sinking air that is the (doldrum) monsoon high developing over Mexico late this weekend or into early this week. Keep in mind that a rapidly cooling equatorial eastern Pacific Ocean (happening currently) is a good thing if you prefer more rain in NM during the monsoon. Why? A cooler eastern tropical Pacific results in fewer deep tropical thunderstorm clusters during summer. It`s these thunderstorms that transfer large amounts of latent heat high up into the lower atmosphere creating large temperature differences between the tropics and poles as say compared to last summer during El Nino. Weaker temperature differences between the poles and tropics result in a weaker than average southern stream or subtropical jet stream. So what? Less deep convection this upcoming summer typically helps any low level moisture advection remain in place longer for daily rounds of afternoon thunderstorms. If the subtropical jet is relatively strong like last summer due to the warmer waters associated with El Nino, dry airmasses from the Mojave Desert and Great Basin are more frequent and more likely to scour out low level moisture from western and central NM especially. && .AVIATION... (12Z TAFS) Issued at 528 AM MDT Wed May 15 2024 Showers and storms will develop over the high terrain of western and northern NM around 18Z, increasing in coverage through the afternoon. As storms drift of the northern mountains into the northeast and east-central plains, they will intensify and potentially produce large hail and damaging wind gusts. Showers and storms in central and western areas will not be severe, but could produce gusty outflow winds up to 40kts. A backdoor cold front, aided by convective outflows, will surge south and westward overnight into the Rio Grande Valley. Gusts up to 30kts are possible along and behind this boundary. A convergence zone sets up across central NM overnight, increasing the coverage of rain showers. MVFR cigs may develop in a few areas between 06Z and 12Z, favoring locations in and around the northern mtns, including KAXX, KSKX, and KLVS. && .FIRE WEATHER... Issued at 119 AM MDT Wed May 15 2024 Scattered showers and storms will favor western and northeastern NM this afternoon and evening. Storms in eastern NM will organize and potentially cluster together as they move off the central mtn chain into the eastern plains during the mid to late afternoon. Precipitation increases in coverage over central NM overnight and locally heavy rainfall could create flash flooding over recent burn scars along the central mtn chain. The severe storm threat on Thursday will focus over the southeast plains where 0.25"-1" of rain may fall. Dry weather returns Friday as the upper-low exits to the east. The drier airmass combined with rising heights and mostly clear skies will bring temps up to the highest values of the season thus far Friday and over the weekend. Increasing southwest winds will create excellent ventilation areawide during this time period, but critical fire weather conditions will also increase in coverage Sunday into the early part of next week. && .PRELIMINARY POINT TEMPS/POPS...
