NWS Las Vegas, NV wrote its last area forecast discussion before the first event at Jul 24, 2:54 PM MST, 4 hours 51 minutes earlier.
Area Forecast Discussion National Weather Service Las Vegas NV 254 PM PDT Wed Jul 24 2019 .SYNOPSIS...High pressure centered east of the area will continue to provide a favorable monsoon flow into the area through Thursday, resulting in scattered thunderstorms again on Thursday. A drying trend begins Friday with hot and dry conditions expected over the weekend. Monsoon moisture is forecast to return early next week with another round of thunderstorms possible by Tuesday. && .DISCUSSION...tonight through Friday. Isolated to scattered thunderstorms will continue through the evening hours decreasing overnight as support from an inverted trough ends as it lifts away from the area. A Flash Flood Watch remains in effect until 11 pm this evening for portions of southern California, southern Nevada and northwest Arizona as the inverted trough interacts with unseasonably high PWATs and weak instability to increase rain efficiency and bring an elevated risk for flash flooding. Essentially, little movement is forecast in the position of high pressure on Thursday with little change in available moisture. However, the area of concern for more widespread storms and an increased potential for flash flooding shifts to the northern regions of the CWA. A Flash Flood Watch is in effect for Thursday afternoon/evening for portions of the southern Great Basin. High pressure shifts to southeast Arizona on Friday with precipitable water values decreasing somewhat. However, moisture remains more than sufficient for storm development, especially across the Sierra and southern Great Basin due, in part, to support provided by a trough moving into central California. This feature could help support nocturnal convection Friday night as it passes across southcentral Nevada. High pressure moves directly over the area this weekend and as a result, stabilizes the airmass over the region and ends thunderstorm chances for the time being. In addition, temperatures are forecast to soar to several degrees above normal with MOS guidance showing temperatures on Sunday in Las Vegas at or above 110 degrees. In response, excessive heat indices rise on Sunday but then lower again Monday as temperatures drop off. The high pivots east of the area Monday and re-positions near the Four Corners by Tuesday signaling a return of monsoon moisture and increasing chances for thunderstorms. In response to the increased moisture, temperatures would fall back to below normal by mid week. && .AVIATION...For McCarran...A challenging forecast through the TAF period as an active monsoon pattern lowers confidence. Complex of storms near the Peach Springs corridor this afternoon will likely do one of two things, either hold together and continue moving west into the Las Vegas Valley, or collapse, and send strong outflow towards the valley. In either case, expect another chance for thunderstorms and associated hazards around the valley this evening, then again Thursday morning. Turbulence and icing hazards expected with thunderstorms near the valley and approach corridors, along with gusty and erratic surface winds. CIGs should remain above 10 Kft with thunderstorms. For the rest of southern Nevada, northwest Arizona and southeast California...Monsoon thunderstorms will keep the forecast tricky through the TAF period. A developing complex in northwest Arizona will the be primary concern this evening, along with any outflow it may produce. On Friday, thunderstorms most likely north of a KNID- KIGM line with heavy rain and gusty, erratic winds as the primary threat; generally southwesterly winds south of the line. CIGs with any thunderstorms will likely remain above 10 Kft, but expect icing and turbulence hazards aloft in the region. && .SPOTTER INFORMATION STATEMENT...Spotters are encouraged to report any significant weather or impacts according to standard operating procedures. && DISCUSSION...Salmen AVIATION...Steele For more forecast information...see us on our webpage: http://weather.gov/lasvegas or follow us on Facebook and Twitter DISCUSSION...Salmen AVIATION...Steele For more forecast information...see us on our webpage: http://weather.gov/lasvegas or follow us on Facebook and Twitter
