Area Forecast Discussion National Weather Service Las Vegas NV 1024 AM PDT Thu Apr 21 2022 .SYNOPSIS...An active synoptic pattern will continue windy conditions through Friday for parts of the region. Temperatures will cool off in response to a storm system today and Friday and gradually warm up heading into early next week. This next system is also expected to bring late season, high elevation snowfall and valley rainfall but accumulations are expected to be minor. && .UPDATE...Breezy to gusty morning so far across the region, overall gusts have been generally 25-35 mph with some isolated gusts over 40-45 mph. Winds are expected to increase through the afternoon, with the strongest winds expected north of the I-15 corridor, specifically across Lincoln, Nye and northwestern Clark counties. Widespread gusty winds will relax some overnight, but remain gusty across the higher elevations. The region is expected to remain mostly dry through this evening with precip chances increasing tonight and through tomorrow morning from northwest to southeast across the CWA. Current forecast looks on track and no updates were needed. && .PREV DISCUSSION... /issued at 452 AM PDT Thu Apr 21 2022/ .SHORT TERM...Today through Friday. In general, expectations have not changed much in regards to this next low pressure system expected to bring strong gradient winds to the region, a strong cold front, and even precip to parts of the CWA. QPF concerns mentioned in yesterday's discussion are being realized with the latest 00Z HREF LPMM values. Most hi-res guidance with their improved spatial resolution are depicting a much more dry outcome for precip across the CWA due to a lack of moisture overcoming the Sierra block. The 00Z HRRR especially blocks almost all precip for even the Owens Valley which synoptic models were maintaining aggressive QPF for. Latest NBM does follow suit appropriately, backing off QPF numbers as much as 80% in some locations. WPC was not as aggressive in backing off desert valley numbers but either way, values were minor anyway. At this point, other than the Sierra, the best chance for rain continues to be where thunderstorms are the most likely, in direct vicinity of the low center as it swings over and when the cold front pushes through. 00Z HRRR does depict a broken line of convection moving southeast Friday afternoon into Clark County as the front arrives, and that looks like the best shot for any rain. Given the very dry pre-frontal regime however, this may turn out to be more virga than actual showers, and if so, could be a secondary area of strong wind gusts affecting the valley tomorrow evening. Will have to watch that closely as it could have implications for the Valley. Beyond precip, the main story looks to again be gradient winds. Latest trends in cold front arrival is a bit slower than this time yesterday, which means pre-frontal gradient winds could persist a bit longer than originally expected. Also, 00Z HREF means gradually increase across the board with each run, which is often the case with the hi-resolution models in this type of gradient set up. While means are modestly higher, it's enough to push wind gust potential to near advisory levels for much of the CWA at this point. Wasn't going to expand the advisory as much as we ended up doing, but there was some concern with the upper end of the probabilistic envelope showing much higher winds than advertised in the deterministic models. .LONG TERM...Saturday through Thursday. Dry northwest flow will be over our area Saturday in the wake of the aforementioned trough as it pulls away over the Four Corners and Rockies. North-northwest surface winds Saturday still look light to moderate with sustained speeds 10-15 mph across most of the area and a little stronger near Laughlin- Bullhead City with gusts 30-35 mph. High temps will be 3-5 degrees below normal Saturday with highs in the 70s across the desert zones and in the 80s in the Colorado River Valley and Death Valley. Model ensembles indicate a large ridge amplifying and migrating over the western states Sunday and Monday then moving moving away to the east ahead of a broad Pacific trough approaching the West Coast by Tuesday. This will lead to a warming trend with temperatures climbing around 5 degrees each day resulting in highs in the 90s over the deserts by Tuesday as southwest winds generally 15-25 mph develop in response to the trough. Model ensembles begin to diverge with the timing and depth of the inland progression of the trough Wednesday and Thursday. The NBM indicates a slight decrease in temperatures those days with breezy to windy conditions each afternoon. && .FIRE WEATHER...A Red Flag Warning remains in effect today across much of Clark County, the Colorado River Valley, and northwest Arizona. The upcoming storm system is still expected to enhance surface winds out of the southwest this morning and by the time RH values reach their minimums in the afternoon, about a 6-8 hour period of critical fire weather conditions looks likely for desert valleys especially. After 03Z Friday, winds may stay elevated, but RH values should be increasing and stay above critical thresholds through Friday. In fact, light wetting rains are possible for parts of Clark and Mohave counties Friday. && ..AVIATION...For Harry Reid...Winds will be on the increase this morning and continue through the afternoon with gusts around 40kts possible. Expect the strong winds to continue tonight through Friday morning before decreasing Friday afternoon. In addition, there is a chance of seeing a few showers develop on Friday along with a brief period of CIGS of 6-8kft as a cold front drops south through the region. For the rest of southern Nevada, northwest Arizona and southeast California...At KDAG, west winds increase late this afternoon and continue through much of Friday with gusts over 40kts possible. Expect areas of blowing dust and reduced visibility at times. KBIH will see increasing winds late this morning continuing through early evening before decreasing. There will be a chance of showers mainly Friday morning at the KBIH airport. Elsewhere, gusty south-southwest winds will develop later this afternoon and continue through Friday with gusts up to 30 kts in the Colorado River Valley and up to 40kts in the Las Vegas Valley. && .SPOTTER INFORMATION STATEMENT...Spotters are encouraged to report any significant weather or impacts according to standard operating procedures. && UPDATE...Peters SHORT TERM...TB3 LONG TERM...Adair AVIATION...Salmen For more forecast information...see us on our webpage: https://weather.gov/lasvegas or follow us on Facebook and Twitter
