NWS Las Vegas, NV wrote its last area forecast discussion before the first event at Jul 8, 8:54 AM PST, 4 hours 6 minutes earlier.
Area Forecast Discussion National Weather Service Las Vegas NV 954 AM PDT Fri Jul 8 2022 .SYNOPSIS...Temperature will steadily warm through the weekend and into early next week. Ridging over the Four Corners region responsible for our warming temperatures will aid in monsoonal moisture into AZ and eventually across southern NV and southeastern CA. Best storm chances are expected mid to late week next week. && .UPDATE...As expected, temperatures are currently running 2-3 degrees warmer than yesterday. Temperatures will continue to increase a few degrees each day through early next week. Southerly winds will pick up again this afternoon with 20-30 mph gusts expected for much of the area. Southerly wind gusts are expected to pick up again tomorrow afternoon with winds calming down on Sunday. The current forecast remains in good shape with no major changes necessary at this time. && .SHORT TERM...through Monday. Generally, quiet and warm weather is expected to continue through the weekend. Breezy southerly winds are expected again this afternoon and Saturday afternoon with gusts up to 20-30 mph. Besides some afternoon breezes, expect temperatures to steadily rise through the weekend as the broad ridge to our east begins to shift westward and build through the weekend and into early next week. Even with the increase in temperatures, temperatures will only peak to about 5- 7 degrees above seasonal normals for both the highs and lows, resulting in widespread "Moderate" HeatRisk values. Even though there is a weak shortwave that moves through NorCal over the weekend, the expansive ridge overhead is not expected to weaken at all by it. This very strong (600dm) ridge will be centered near the Four Corners region for multiple days, leading to multiple days with southeasterly flow which will aid in moisture across AZ and eventually into southern NV and southeast CA next week. The first arrival of moisture will be confined to the mid-levels, mainly in Mohave County Saturday. Even so, the best storm chances will mainly be confined to eastern AZ Saturday, with outflows moving westward Saturday night into the Phoenix metro area. Latest hires indicates 1-2 members producing isolated shallow, mid-level showers/storms may be possible near Grand Canyon and far northwest Mohave County Saturday afternoon. Surprisingly, CAMPoP didn't jump onto those minimal chances and neither did the NBM so the current forecast still communicates a dry forecast for Saturday. Given the arrival of modest mid-level moisture late evening Saturday in far northwest Mohave County, a few virga showers are possible, but confidence is low. A more likely scenario is cumulus development along the higher terrain. By Sunday, better mid-level moisture is expected to filter across Mohave County along with slightly better CAPE (50-100 J/kg). Given very dry low levels, virga showers with a few lightning strikes may be possible Sunday across western Mohave County. Current forecast is still communicating dry conditions Sunday but as we get hires data PoPs may slightly increase Sunday afternoon. Latest NAM and GFS PWATs plus 15-20 knot 700mb winds are indicating a decent signal for a low-level moisture surge on Sunday morning. If that were to occur, PoPs would likely increase more than what's currently forecast as well. By Monday, the board ridge expands even further west, slightly increasing heights, potentially making Monday the hottest day of the week. Similar low-grade moisture (0.75"-1.00" PWs) and very limited instability with warm air aloft, will continue to suppress storm development Monday afternoon. Even so, conditions will be similar to Sunday, and a few isolated shallow, mid-level virga storms may be possible Monday. .LONG TERM...Tuesday through next Thursday. On Tuesday, the ridge of high pressure responsible for the above- average temperatures will continue to strengthen. This will both maintain elevated temperatures and assist in pulling monsoonal moisture up from northern Mexico into the Desert Southwest. PWAT values will exceed 1.00" across portions of southeastern California, southern Nevada, and northwestern Arizona, peaking on Thursday, with the ECMWF ensemble means bringing PWATs over 1.25" into Las Vegas. PoPs this far out have little confidence, with highest (albeit slight) values persisting over northwestern Arizona. NBM PoPs are likely underdone when compared to the ECMWF and GFS 24-hour QPF ensemble means and considering the favorable monsoonal set up; however, it is worth noting that this morning's run of the NBMv4.0 has increased PoPs and spread them further west Wednesday and Thursday than runs 12 hours ago, so it is likely that this trend will continue as we get closer and synoptic details become more clear. What we do know is that above-average temperatures will persist through the forecast period, with Tuesday being the hottest day prior to the mid-level moisture moving into the region. Widespread "Moderate" HeatRisk will continue, with a few pixels of "High" HeatRisk along the Colorado River Valley. No heat-related headlines expected. Monsoonal convection can be expected across northwestern Arizona as soon as Wednesday afternoon, with areas further west and favoring the higher terrain not out of the question. && .AVIATION...For Harry Reid...Light and variable winds through mid- morning will give way to south-southeast winds by late morning. Some variability in wind directions is expected at times before 20Z, but generally should be between 140 and 180. After that time a more southerly wind is expected with a few gusts up to 20kts possible from mid-afternoon until just before sunset. Winds will become south- southwest for a period this evening before becoming light and variable once again overnight. Occasional high clouds will move across the area today, but no operational impacts are expected. For the rest of southern Nevada, northwest Arizona and southeast California...South winds gusting to 25kts at times can be expected for most sites once again this afternoon. KDAG will be the exception to this where light and variable winds are expected through mid-afternoon when gusty westerly winds will redevelop. Occasional high clouds will move across the region today, but no operational impacts are expected at area terminals. && .SPOTTER INFORMATION STATEMENT...Spotters are encouraged to report any significant weather or impacts according to standard operating procedures. && UPDATE...Stessman SHORT TERM...Peters LONG TERM...Varian AVIATION...Planz For more forecast information...see us on our webpage: https://weather.gov/lasvegas or follow us on Facebook and Twitter
