Area Forecast Discussion...RESENT National Weather Service Elko NV 201 PM PDT Thu Sep 9 2021 .SYNOPSIS...A couple of showers linger into this evening and overnight, but active weather ramps up for Friday. A mix of wet and dry thunderstorms are expected, coupled with gustier winds. Quiet weather conditions return for most of us on Saturday. && .SHORT TERM...Tonight through Saturday A shortwave trough moving in to our region brings a swath of moisture, reflected in PWAT values of 0.75"-1" for tomorrow. Guidance suggests some values may exceed an inch, but this may only occur close to the NV/ID border. Highest QPF totals are likely to come from Humboldt and Elko counties.It would be fair to generalize that the bulk of wetting thunderstorms should be along and north of I50, but south of the highway is more likely to see a mix of some wet and dry thunderstorms. Winds are also going to be gusty with much of the CWA seeing winds along the lines of 15 to 20 mph and gusts approaching 30 to 35 mph. Erratic and stronger winds are likely in the vicinity of thunderstorms. As the trough lifts to our north and east, most of us should see a quieter Saturday. The only exception is the possibility of some light showers and some dry thunderstorm activity in southeastern Elko and White Pine counties. Afternoon highs drop to the 80s with overnight lows mostly in the 40s. .LONG TERM...Saturday night through next Thursday Any lingering showers/storms should quickly dissipate Saturday night across the far east. For Sunday, expect a fairly westerly zonal setup with ridging to our south. Could be a few showers/storms across eastern Elko county with lingering moisture along weakening boundary. For next week, the overall pattern continues to favor a generally progressive westerly flow with a couple of troughs passing through the region. Deterministic and ensembles definitely differ on timing and other details of each system, but general trend is for one to pass through Monday/Tuesday timeframe with second one mid to late week. Moisture looks to be quite limited with these systems, but could be a few showers and even a storm or two across mainly northeast NV. Best potential looks to be Sunday and Monday afternoon/evening. Warm but more seasonable temps for the extended with highs generally in the upper 70s to 80s; around 4-8 degrees above normal for this time of year. Trending a bit cooler (70s to lower 80s) for Thursday with larger trough favored to be over western US. Nighttime lows generally in the 40s to lower 50s. Breezy winds at times with each trough passage. && .AVIATION...VFR conditions expected through the period. Showers and thunderstorms expected to develop over central NV and push north through this evening. Best potential for impacts looks to be at ELY and EKO with strong erratic winds possible. Otherwise winds will be 12-20g10g28kts through evening, then becoming 8-13kts overnight. Friday will again see winds 12-20g20g28kts, slightly stronger at ELY. Better chance for showers/storms to impact the taf sites as well, with strong erratic winds and small hail possible. && .FIRE WEATHER...Mostly wet thunderstorms are expected in most FW Zones on Friday, but parts of 425 and 426 have less of a chance at thunderstorms bringing 0.10”+ of rainfall. Dry thunderstorms are expected to stay isolated in coverage. Even though gustier winds are expected, this weather system is also bringing in a swath of moisture that’ll bring minimum RH values over 20%. && .LKN WATCHES/WARNINGS/ADVISORIES... None. && 84/87/87/84
