Area Forecast Discussion National Weather Service Las Vegas NV 1256 AM PDT Sat Jun 17 2023 .SYNOPSIS...More typical in June, dry weather returns for the next week. However, conditions will become windy on Sunday, and especially Monday as a deep area of low pressure settles over the Pacific Northwest. Temperatures briefly heat up this weekend, with Las Vegas having an outside chance at its first 100 degree day of the year. For the remainder of the week temperatures will stay below normal. && .SHORT TERM...Through Monday night. Last of the clouds has exited northwest Arizona that was associated trough shifting into the Four Corners. Wonderful outside early this Saturday morning under clear skies, light winds and below normal temperatures. If you have outdoor plans, today will be the best day of the next three. Temperatures will warm but they will still fall several degrees below normal along with slight southerly breezes developing in the afternoon. Pattern starts to take a turn for the worse on Sunday and Monday. Models have been consistent in the development of a deep trough over the Pacific Northwest. NAEFS probabilities indicate mean H5 heights are going to be extremely low for late June as compared to climatology. In fact on Monday, 100% of the the NAEFS members have H5 heights lower than any other late June reanalysis. Main impact this trough will have on the area is the return to our typical windy Spring periods. Pressure and thermal gradients start to respond on Sunday with strongest southwest winds favored across the western Mojave Desert and Spring Mountains. On Monday, widespread strong southwest winds expected areawide as gradients increase further. At this point, would like to see another model run before drawing up our wind advisory. Deep layered mixing will contribute to making Sunday the warmest day of the next 7 with highs near normal. On Monday, temperatures are expected to cool some 4-8 degrees. Impacts from the wind will be areas of blowing dust, difficult travel for high profile vehicles, as well as boating conditions, and finally potential power outages. .LONG TERM...Tuesday through Friday A deep West Coast trough is expected to linger over the region through much of next week. This will keep the area in a dry and cool weather pattern. While exact details of how the upper level system will set up through the second half of the week, cluster analysis supports this continued cyclonic flow with the trough slowly weakening and lifting out in some fashion through the period. How this evolves will play a role in the temperature and wind forecast, however in general-there is high confidence for below normal temperatures and general (non-impactful) afternoon breezes each day. CPC highlights this as well with high probabilities (70%+) for below normal temperatures in the 6-10 day outlook for the Southwest US. && .AVIATION...For Harry Reid...Light and variable wind this morning will become east or southeast at less than 8 kts mid-day. Around 23Z, winds are forecast to go southerly at 8-12 kts. A south- southwest wind around 12 kts will likely persist through the night. Other than some clouds over the mountains around 10 kft this afternoon, skies will be clear. For the rest of southern Nevada, northwest Arizona and southeast California...No significant clouds forecast across the southern Great Basin and Mojave Desert through Sunday. Generally surface will be out of the south-southwest at 8-12 kts today. Gusty west winds will stay elevated across the Mojave Desert tonight with additional strengthening on Sunday. Gusts of 30-40 kts will be most common around KDAG Sunday. && .SPOTTER INFORMATION STATEMENT...Spotters are encouraged to report any significant weather or impacts according to standard operating procedures. && SHORT TERM/AVIATION...Pierce LONG TERM...Nickerson For more forecast information...see us on our webpage: https://weather.gov/lasvegas or follow us on Facebook and Twitter
