NWS Las Vegas, NV wrote its last area forecast discussion before the first event at Jul 31, 6:56 PM PST, 5 hours 4 minutes earlier.
Area Forecast Discussion National Weather Service Las Vegas NV 756 PM PDT Wed Jul 31 2019 .SYNOPSIS...Shower and thunderstorm chances are forecast to decrease Thursday and Friday, with temperatures rising back above normal over the weekend. Moisture could spread back westward early next week. && .EVENING UPDATE... Shower and storm coverage has diminished right about on queue this evening as models had depicted. Still a couple isolated weak cells spotted across the region, one being just east of Barstow, a couple more in southern Mohave Co, and a couple more in the panhandle of Lincoln Co. As daytime heating fades and moisture continues to exit the area, this trend should continue. Short term models show little to no activity expected after 03Z this evening. Thus added some mentionable PoPs for the Barstow/Daggett cell, and decreased PoPs elsewhere. Also, hourly temperatures were quite a bit off from reality so populated with latest obs and utilized a cooler model guidance for the Min T overnight. && .PREV DISCUSSION... /issued at 251 PM PDT Wed Jul 31 2019/ .AVIATION UPDATE...The storm cell that formed on the southwest side of the Las Vegas Valley this afternoon produced an outflow that impacted the Vegas Valley TAF sites. Winds have undergone a southwesterly shift and will remain from the southwest until gusts die down around sunset. VCTS will remain in KLAS and KHND through 01z. TAFs have been updated to reflect this change. && .PREVIOUS DISCUSSION...251 PM PDT Wed Jul 31 2019/ .DISCUSSION...Thunderstorm chances will continue into the evening before ending overnight. For Thursday, models have high pressure centered over New Mexico and northern Texas with the main monsoon moisture plume shifts east over eastern Arizona/western New Mexico. 1-1.5 inch precipitable water values are forecast over the eastern potions of San Bernardino County, Clark County, southern Lincoln County and all of Mohave County. 850 mb dewpoint temps are forecast to be lower but still sufficient for efficient rain producing storms, especially in Mohave County. Some drying is forecast across the western regions but inch PWATs hang tough over the southeastern CWA. We are currently forecasting dry conditions Friday however this could change if some of the latest model moisture and instability trends hold. In fact, the same could hold true for the weekend and into early next week before drier/more stable air moves in. && .AVIATION...For McCarran...The southeasterly winds that we saw this morning have been replaced by due easterly winds that will remain in place through the remainder of the afternoon with gusts as high as 25 kts. Once gusts die down around sunset, winds will persist out of the east around 8 kts before becoming light and variable through the overnight hours. Light southeasterly winds expected to pick up Thursday early-afternoon and last through much of the day. With regard to precipitation near the terminal, convection began later than originally expected. An isolated shower or storm in the Las Vegas Valley cannot be ruled out for the remainder of the afternoon, though confidence is low; VCTS is in the TAF until 01z. Low clouds aoa 12 kft will rise overnight resulting in SCT aoa 20 kft for the remainder of the TAF period. For the rest of southern Nevada, northwest Arizona and southeast California... Southern Nevada TAF sites can expect gusty easterly winds to remain in place until around sunset before decreasing to a sustained 8 kts through the early evening. Overnight, light and variable winds take hold. During the early-afternoon hours of Thursday, light southeasterly winds will pick up and last through the afternoon. Colorado River Valley TAF sites will experience gusty southerly winds until around sunset when winds become light and variable. Isolated showers and thunderstorms in the vicinity of the southern Nevada and NW Arizona terminals remain possible this afternoon. VCTS will stay in the TAFs for these sites until 01z. CIGs expected to rise through the overnight hours resulting in clear skies for the SE California sites and SCT aoa 20 kft for the remainder of the sites through the TAF period. && .SPOTTER INFORMATION STATEMENT...Spotters are encouraged to report any significant weather or impacts according to standard operating procedures. && UPDATE...TB3 DISCUSSION...Salmen AVIATION...Varian For more forecast information...see us on our webpage: http://weather.gov/lasvegas or follow us on Facebook and Twitter
