Heavy rain from a good monsoonal push, caused flash flooding in eastern Nevada.
The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Elko, NV wrote its last area forecast discussion before the first event at Aug 13, 12:20 PM PST, 4 hours 10 minutes earlier.
Area Forecast Discussion National Weather Service Elko NV 120 PM PDT Sat Aug 13 2022 .SYNOPSIS...Active weather pattern to continue into the next as monsoonal moisture is drawn into the Silver State. Coverage and activity looks to wane for Sunday and the first part of next week before intensifying again for the late-week period. && .SHORT TERM...Today through Sunday night A very similar setup to yesterday is expected today with respect to storms, once again there will be a sharp east to west gradient today with respect to storm chances. A sharp theta-E gradient sits near and along the Lander/Eureka county line. Although not exactly co-located, are strong gradients of PWAT values, and surface dew points. This quasi-dry-line feature is also highlighted in this mornings wind field with W-SW winds in Humboldt and Lander Counties, and SE-E winds in eastern NV. To the west drier air has filtered into the area, with surface dew points in the 20s, RH values in the single digits, and PWAT values of less than 0.4” nearly eliminating any probability of convection as well as elevating fire weather concerns. To the east of that boundary PWAT values of 0.75” or greater exist and dew points are in the 50s. Storm motion will still be rather slow to erratic given weak steering southwesterly flow aloft over the region, and with that a localized flash flooding threat exists again with the stronger cells that do form. The main questions for the day given this setup is how far east will this dry-line push, and if/how fast dry air aloft over western NV will mix eastward. Models are split as to possible solutions to these questions which will have a big impact on possible thunderstorm development today especially for W and SW Elko County. Sunday looks to be one of the more quieter days with regards to thunderstorm chances as the better monsoon moisture looks to be pushed into UT. But a few isolated storms will still be possible along the UT NV border. As for winds and temperatures, look for highs in the middle 80s to mid 90s today and Sunday, with light S to SW winds of 5 to 10 MPH. The only areas to watch will be Humboldt and western parts of Lander county give the warm and dry conditions, it is also likely to see the strongest winds outside of any convection as W-SW of 15 to 25 MPH are expected with the strong heating. .LONG TERM...Monday through next Friday. Models are trying to show an upper level ridge circulation trying to develop over northern Nevada beginning on Monday, with a weak upper trough out to the west in the eastern Pacific. Convective activity is expected to be limited for those areas south of the I-80 corridor. Highs on Monday will be in the 80s and 90s. Quiet weather is expected during the overnight with lows in the 50s and 60s. The ridge is expected to shift slightly to the east with troughing evident over Arizona and southern Nevada by Tuesday. Another round of convective activity is anticipated across central Nevada, but the return flow of the upper ridge may bring moisture around the western periphery of the ridge. Have kept pops low across north- central Nevada at this time. Otherwise, temperatures will continue to remain in the 80s and 90s with the warmest temperatures seen in the northern sections. Light showers are possible in portions of Humboldt county during the overnight with lows in the 50s and 60s. Wednesday through Friday, the upper ridge will maintain a position somewhat east of the area. This will keep a slow moisture seep over the forecast area, leading to gradual increases in thunderstorm activity northward. Afternoon highs will continue to be in the 80s and 90s with overnight lows in the 50s and 60s. Winds will remain on the light side. && .AVIATION...Showers and thunderstorms are possible at the KEKO and KELY terminals this evening. KBAM and KWMC will remain storm free once again. Winds will remain light at less than 20KT. Look for convective activity tomorrow afternoon across KEKO-KELY-KTPH with sunny conditions for KWMC and KBAM. && .FIRE WEATHER...Very dry air and elevated fire weather concerns have settled back into Humboldt and NW Lander counties. Expect single digit RH values across zones 437 and 424 with west to southwest winds in the range of 10 to 20 kt. Otherwise, no significant fire weather concerns for the next several days across other zones with general winds remaining light and chances for showers and thunderstorms continuing. && .LKN WATCHES/WARNINGS/ADVISORIES... None. && 98/86/86/98
