589 FXUS65 KVEF 271916 AAA AFDVEF Area Forecast Discussion National Weather Service Las Vegas NV 1216 PM PDT Mon May 27 2024 .SYNOPSIS...A stray thundershower or two is possible into early this evening in the southern Sierra but otherwise dry conditions are expected areawide. Afternoon breezes can be expected each day with temperatures several degrees above normal into early next week. && .DISCUSSION...Extensive cumulus field across the central and east central Nevada mountains just after noon. Satellite also shows cumulus congestus becoming more apparent on the southern Sierra. Latest run of the HRRR continues to shows several showers, maybe a stray thunderstorm developing after 2 pm along the Sierra crest, from upper Bishop Creek north into Mono County. Elsewhere, seasonably warm temperatures will lead into a pleasant evening for those final Memorial Day outings. Hate to sound like a broken record, but model agreement remains good in the synoptic scale features over the next week. Only real player will be the passage of a trough through the northern tier states Tuesday-Thursday. No significant winds expected from the system, just our typical daily south-southwest breezes. Only minor day-to- day temperature fluctuations with high generally 4-7 degrees above normal. Last item, there is a wildfire in the lower CRV north of Yuma that could send smoke/haze northward into the Parker Strip/southern Mohave County at times. && .AVIATION...For Harry Reid...Light east winds are expected through the early afternoon. After 21Z, there is moderate confidence (60% probability) that winds will become southeast. If this does not occur, east winds will continue through the afternoon. No matter what direction sets up for this afternoon, winds will remain under light with a nearly 100% probability for wind speeds to remain under 10KT. Typical overnight south-southwest winds set up this evening and will continue through early Tuesday morning. After a brief period of light and variable winds Tuesday morning, southeast winds at 8KT or less are expected to set up around 18Z. Sometime in the afternoon, winds will shift southwest and increase. This likely wont occur until at least 21Z, but could be as late as 23Z-00Z. Wind speeds over 10KT are likely (80% probability or higher), with a low chance (30%) for gusts over 20KT, when the southwest winds arrive. No significant clouds or weather are expected through the period with just a few cumulus clouds developing around 12kft this afternoon. For the rest of southern Nevada, southwestern California, and northwestern Arizona...Breezy south to southeast winds are expected at KBIH this afternoon. Winds will remain elevated out of the southeast after sunset before transitioning to a typical light northwest wind around midnight. Gusts to around 20KT are possible at KBIH this afternoon. At KDAG, typical breezy west winds will develop around 00Z, with gusts falling off around midnight but continued elevated wind speeds through the night. Otherwise, light and diurnal wind patterns are expected across the region today through tonight.
