NWS Elko, NV wrote its last area forecast discussion before the first event at Aug 3, 12:42 AM PST, 11 hours 1 minute earlier.
Area Forecast Discussion National Weather Service Elko NV 142 AM PDT Thu Aug 3 2023 .SYNOPSIS...Look for isolated to scattered showers and thunderstorms today, but areal coverage will diminish each afternoon as drier air will be moving into the area. Temperatures will be near normal. && .SHORT TERM...Today through Friday night. Isolated to scattered showers with several thunderstorms can be seen on radar at this time. A moist airmass continues to reside over the forecast area as many locations have dewpoints in the upper 40s to mid 50s. Model solutions are showing weak ridging trying to build over northern and central Nevada today. The moist air mass will remain in place as precipitable water values are forecast to be at or above 0.80 inches north of the US Highway 50 corridor. Available CAPE will be around 200-600 J/kg and negative lifted indices will allow showers and thunderstorms to again develop this later morning and afternoon. Forecast storm motion will be a little faster than yesterday but brief moderate rain from some of the stronger convective cells are possible. Outflow winds to 40 mph are also possible from some of the stronger cells. Highs today will be in the 80s. Some shower activity will continue into the evening, but will dissipate before midnight. Overnight lows will be in the 40s and 50s. Weak ridging continues to build slowly over northern and central Nevada on Friday. Residual moisture and instability will be limited to locations north of and including the I-80 corridor. Winds will remain light with highs generally in the 80s to lower 90s. Look for showers to continue during the evening but ending before midnight. Lows will be in the 40s and 50s. .LONG TERM...Saturday through Thursday Saturday through Sunday: Upper level low which has been slowly moving through the Great Basin region will finally be departing for Montana but not before giving far northern NV one last day of thunderstorm chances Saturday. Sunday through Tuesday: Upper level ridge will slide back west but the upper pattern looks to remain rather flat over Nevada due to influence of a upper low over eastern Washington, Idaho panhandle region. This low will not move much for the first part of the week. With the flat flow NV will be under the influence of westerly winds aloft so quiet weather will be expected but good news temperatures will be warming, but will remain near normal. After Tuesday, models disagree with the evolution of the upper pattern ans the ECMWF wants to keep the flow zonal. However, the GFS wants to dig an upper trough into the Pacific NW which would push a decent cold front through northern NV Wednesday morning dropping temperatures well below normal along with shower chances. Given the lack of agreement at this time, will keep the forecast dry for now. Temperatures will begin a slight warming as thunderstorm chances wane. Highs will range in the lower 80s to lower 90s through the week. Overnight lows will range in the mid 50s to mid 60s for most with the exception of SE Elko county with lows in the mid to upper 60s. Winds look to be breezy out of the W to SW with speeds ranging from 10 MPH to 20 MPH with gusts up to 30 MPH in the afternoons, before dropping to 5 MPH to 10 MPH during the overnights. && .AVIATION...Primary flight category will be VFR for all terminals for the next 24 hours. Another round of convection will impact all terminals except KTPH with afternoon showers and thunderstorms Thursday. Brief periods of MVFR or IFR conditions if heavier showers and thunderstorms move over the terminal generally in the 20Z-03Z time frame. Impacts will include brief heavy rainfall, small hail, erratic and gusty outflow winds up to 45KT, lightening, lowered ceilings and terrain obscuration. After 00Z, precipitation will become mainly stratiform with ceilings above 12kft. Chances of TS range from 30-40% along interstate 80 with higher chances farther east near KEKO. KELY is similar with a 30% of TS Thursday afternoon. && .FIRE WEATHER...The moist air mass will continue to reside across most of northern and central Nevada. Isolated to scattered showers and thunderstorms are expected to develop north of and including the US Highway 50 corridor later this morning and afternoon. Some of the stronger cells could drop brief moderate rain, especially in the north and northeastern sections of the state. In addition, strong convective wind gusts to 40 mph are possible as well. Look for the air mass to slowly dry out Friday with the expectation of showers and thunderstorms north of and including I-80. Look for the isolated showers and storms across mainly northeast Nevada through the weekend. Outside of this area, quiet weather will be the rule. No fire weather concerns are noted through the weekend. Highs will be in the 80s to low 90s with dry conditions. && .LKN Watches/Warnings/Advisories... None. && 86/93/98/86

DPThe Elko radar (KLRX), 113 km away, was scanning. The volume nearest the first event began at 19:41 UTC.
2 flash flood, 1 thunderstorm wind. Local standard time, as filed.
Station (MPVN2) Martin Creek Raws, Elevation 6439 feet.
Heavy rain from a thunderstorm caused an area of water approximately six to ten inches deep to run over portions of Tenth Street and Silver Street in Elko. The water covered the road and went over adjacent sidewalks.
Heavy rain from thunderstorms produced localized flooding at the intersections of 5th and Fir Streets. Photos from the public show water 3-6 inches deep over the roadway, with some folks taking to using Kayaks for their amusement.
