Bear Mountain Resort Snow Report

524 FXUS65 KVEF 200725 AFDVEF Area Forecast Discussion National Weather Service Las Vegas NV 1225 AM PDT Mon Jul 20 2026 .KEY MESSAGES... * Monsoonal moisture remains in place over the region through next week, with thunderstorms expected each afternoon and evening. * Seasonably hot temperatures continue, though little relief will be felt overnight as moisture and cloud cover result in warm low temperatures and Minor to Moderate Heat Risk. && .DISCUSSION...Through Sunday. Very little change in the overall short term pattern as deep monsoonal moisture remains in place over the Desert Southwest. As we have seen over the past few days, thunderstorms have generally been firing late morning and afternoon across Lincoln and Mohave counties and drifting west-southwest. Overall, the instability has been generally weak across Clark, San Bernardino, and Inyo counties and any showers or storms that were able to develop were weak and short- lived. For today and Tuesday, PWATs of 1.00-1.50" will remain generally south of 1-15 with around 1.00" PWATs across the remainder of the area, so plenty of moisture will remain in place. Thunderstorm probabilities are greatest once again across Mohave and Lincoln counties, but instability begins to improve across areas like central Nye, Esmeralda, and the higher terrain of northern Inyo counties, where CAPE values increase to around 200-400 J/KG. With the center of the four corners high shifting slightly east, storms will likely have a more west to northwest progression. With a lack of any real forcing, other than daytime heating, expect most of the activity to dissipate after sunset. Still waiting to see what happens with the inverted trough that has been showing up on the past several model runs. Ensembles continue indicating a weak inverted trough/easterly wave that will translate westward midweek, though there is increased uncertainty now regarding whether this feature will make it far enough to the west to have any appreciable impact on local monsoon activity. Uncertainty increases further thereafter regarding the evolution of the upper pattern as a trough takes shape off of the Pacific Northwest. Depending on the amplitude and strength of this feature, it could displace the ridge over the Four Corners Region and temper some of the monsoonal moisture that`s been in place, especially late next week into the upcoming weekend. Temperatures will remain near seasonal normals through mid week, but the overnight lows will remain quite warm due to the monsoon moisture in place, plus any lingering overnight cloud cover from afternoon convection. The hot days followed by mild nights will result in continued widespread Minor and Moderate (Level 1 and 2) Heat Risk each day. Those who will be outdoors will need to ensure they stay hydrated and take breaks in the air conditioning whenever possible. && .AVIATION...For Harry Reid...For the 06Z Forecast Package... Lingering convection over northern Arizona has resulted in a push of southeast winds (140 to 160 degrees true) into the valley this evening. These winds will likely persist through 07Z before diminishing overnight. Winds on Monday will be similar to today, with speeds generally remaining 10 knots or less. Additional convection is likely over the higher terrain of southern Nevada, with more widespread coverage expected over northwest Arizona, so a period of gusty east to southeast outflow winds will be possible again Monday evening. Away from convection, VFR conditions will prevail under SCT to BKN skies with bases AOA 10kft AGL. Temperatures will exceed 100F on Monday between 19Z and 04Z. For the rest of southern Nevada, northwest Arizona and southeast California...For the 06Z Forecast Package...Scattered convection persists across the southern Great Basin and northwestern Arizona late this evening, with gusty outflow winds, heavy downpours, and reduced visibility the main concerns. Winds will decrease across all areas overnight. A similar pattern is expected on Monday, with scattered convection mainly across the higher terrain of southern Nevada and eastern California, and more widespread convection over northwest Arizona. Away from convection, VFR conditions will prevail under SCT to BKN skies with bases AOA 10kft AGL. && .SPOTTER INFORMATION STATEMENT...Spotters are encouraged to report any significant weather or impacts according to standard operating procedures. && $$ DISCUSSION...Gorelow AVIATION...Planz For more forecast information...see us on our webpage: https://weather.gov/lasvegas or follow us on Facebook and Twitter
