What forecasters said that day
The local office's own words before this high wind warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Las Vegas, NV wrote its last area forecast discussion before this high wind warning went out at Aug 19, 1:38 PM MST, 11 hours 33 minutes earlier.
Area forecast discussion, Aug 19, 1:38 PM MST, 11 hours 33 minutes before
Area Forecast Discussion National Weather Service Las Vegas NV 138 PM PDT Sat Aug 19 2023 .SYNOPSIS...Rich moisture related to approaching Tropical Cyclone Hilary will begin to advance into the Mojave Desert today with increasing shower and thunderstorm activity expected. This trend will continue into Sunday as the remnants of Hilary lift northward. Widespread heavy rain, gusty winds, and instances of major flooding are expected. Hilary's remains will exit the region by Monday but moist monsoonal conditions will persist much of the week with daily storm chances and temperatures remaining below normal. && .SHORT TERM...through Monday night. Our region still on track to see historic rainfall through Monday which will lead to significant flash flooding for parts of the Great Basin and Mojave Desert. Currently, Category 2 Hurricane Hilary lies off the southern Baja Peninsula. Satellite shows a considerable amount of mid/high clouds already streaming northward into the region. What has changed from last nights update is that the official track shifted slightly to the east. In intensity, Hilary is forecast to be tropical storm strength as it reaches southern California Sunday afternoon. Hilary will go through further weakening as it moves rapidly northward at around 30 kts becoming extra-tropical Monday. Precipitable water values are currently 150-250% of normal across southern California. As Hilary approaches those values rise to 250- 300% of normal across a large swath of western San Bernardino, Inyo, southern Nye and Esmeralda Counties. This coincides well with WPC's Excessive Rainfall Outlook of Moderate to High Risk for those regions. QPF Outlook still paints 2-4" in the lower elevations and 4" up to as much a 10" for the mountains in those risk area. Eastern Clark and Mohave Counties remain of the eastern side of the heaviest rainfall predictions, falling somewhere between 1-2" possible. This will likely come in several rounds, particularly tonight-Sunday morning and again Sunday night through Monday morning, then tapering off Monday afternoon and evening. Regarding wind threat. With Hilary forecast to be tropical storm strength as it arrives in southern California Sunday afternoon guidance continues to support sub-tropical storm strength south to southeast winds across southern San Bernardino County, lower Colorado River Valley and southern Mohave County. However, there remains some uncertainty in how strong these winds will be as Hilary may interact with the Baja Peninsula and weaken over the next 36 hours. Would like to wait at least 1 more model run before we consider wind advisories or even a short fused high wind warning for southern San Bernardino and southern Mohave Counties late Sunday afternoon and night. Temperatures through the short term period will be well below normal thanks to the abundance of clouds and moisture, with high temperatures Sunday likely to challenge record daily low maximum temperatures for many areas. .LONG TERM...Tuesday through Saturday. Following the exit of what is left of Hilary on Monday, widespread low level moisture will remain in place. Synoptically, an expansive ridge will remain parked over the central US with a southerly flow featured across the southwestern states. This will result in at least low-grade monsoonal conditions persisting most of next week, with daily storm chances favored in the higher terrain, but possibly drifting into the lower elevations in the afternoon and evening hours. Subtle shortwave features embedded in the flow may also result in some days being more active than others and promote more lower elevation activity. For now, NBM PoPs keep fairly generous storm chances going through the week across Northwest Arizona and southern Nevada, with slight chances across most of southeast California. With the abundance of moisture and continued daily storm activity, temperatures remain cooler than average by 5-10 degrees, but should trend warmer heading into the end of the week. && .AVIATION...For Harry Reid...Dense overcast likely will limit any convection in and around Las Vegas the rest of this afternoon and evening. Leading edge of deeper moisture ahead of Hilary will arrive this evening and continue into Sunday morning with periods of moderate rainfall, lower cigs and lower visibility. Prevailing visibility will be 3-5SM with cigs around 3-4 kft, but they could potentially fall below 3 kft. Air mass looks to become more unstable Sunday afternoon with breaks in the clouds as several bands around a decaying Hilary pass across southern Nevada. Prevailing winds should remain less than 10 kts and favor an east to southeast component this afternoon. For the rest of southern Nevada, northwest Arizona and southeast California...Scattered thunderstorms are expected across the region once again today. The best chance is into this evening across northwest Arizona and Inyo County. Any storms that do develop will be capable of producing gusty, erratic winds. Away from thunderstorm activity, winds of less the 10kts generally from the east and southeast can be expected. Moisture from Hilary will begin to spread across the area this evening into Sunday, resulting in steady light to moderate rain developing from south to north. In addition to the moderate rain reduced visibilities down to 2 to 4 SM at times and CIGs less than 2kft will be possible, with the degraded conditions continuing into Sunday night. && .SPOTTER INFORMATION STATEMENT...Heavy rain, high winds, and flash flooding reports are requested through the weekend as the remains of Hurricane Hilary lift through the Western Mojave Desert. && SHORT TERM/AVIATION...Pierce LONG TERM...Outler For more forecast information...see us on our webpage: https://weather.gov/lasvegas or follow us on Facebook and Twitter
