Area Forecast Discussion National Weather Service Elko NV 339 AM PDT Fri Jul 16 2021 .SYNOPSIS...Hot weather continues well into the weekend with a slight cool down for the next couple of days. Potential exists for showers and storms clear into Friday, with central and eastern Nevada as the main focus for storm locations. Look for a break Saturday before activity returns once again Sunday. && .SHORT TERM...Today through Saturday evening. Dry southwest flow over northwest Nevada provides a contrast with the relatively moist unstable environment of eastern Nevada. Ruby Mountains divide the two distinct air masses. The environment is less moist over eastern Nevada this afternoon, resulting in a down tick of convective activity compared to Thursday afternoon. Much of the diurnally driven convection will be centered over White Pine County, but could extend into southeast Elko County and as far west as southern Eureka County. Storms will be pulse types with isolated cores producing brief heavy showers. A weak upper level disturbance shears northeast across the northern Great Basin, leading to an eastward push of drier air. Some mid level moisture lingers over east central Nevada. While some build-ups will occur, uncertain whether these evolve into isolated storms since precipitable water is lower. .LONG TERM...Saturday night through next Thursday...All models continue to depict a strengthening upper level ridge near the four corners region. Meanwhile an upper level low will be off shore of western Canada. The resulting southerly flow will bring subtropical moisture northward. Look for increasing moisture over central Nevada as precipitable water values increase to over 0.80 inches. Storms could start out as a mix of wet and dry along and south of the US Highway 50 corridor, while north of this line, storms are anticipated to more on the drier side. Storm speeds are forecast to be on the slow slide at 10 knots or less however. High temperatures will be in the 90s to low 100s, though temperatures in northern Nevada may be cooler due to possible cloud cover. Light showers are expected during the overnight, especially in central Nevada. Overnight lows will be in the 50s and 60s. By Monday, the model solutions are continuing to show the upper ridge across the Rockies, mainly in southwestern Wyoming. A mean southerly flow will remain, allowing for moisture moving northward. Precipitable water values will also increase, reaching as high as an inch or so in eastern Nevada, with drier air remaining in portions of Humboldt county. CAPE values are forecast to be around 500 or so J/kg in central Nevada and so went with mainly wet storms for the forecast area. One concern that needs to be watched is the threat for heavy rain and possible flooding from Monday and beyond. Gusty winds to 50 mph will also be possible with storms. Highs will be in the upper 80s to mid 90s with the cooler temperatures being seen in central Nevada due to the cloud cover. Some isolated showers may be possible during the overnight with lows in the 50s and 60s once again. On Tuesday the upper ridge will wobble in eastern Utah and northwest Colorado. This will keep the moisture across mainly central and eastern Nevada. The best CAPE will also remain in eastern Nevada. 0-3km shear of 25 knots will be coincident in eastern Nevada. Shear will be better in northwestern Nevada but CAPE will be more limited. Even so, could see some strong to isolated severe storms possible Tuesday and will need to keep an eye on this. Highs will be in the upper 80s to mid 90s once again. SOme light showers may be possible in the north, but otherwise, skies are expected to be mostly cloudy with overnight lows again in the 50s and 60s. For Wednesday and Thursday, all models are still showing the upper ridge over Colorado and Wyoming. An upper trough will enter the picture off the British Columbia coast. Precipitable water values remain at an inch or more across northern and central Nevada. Will continue to see showers and thunderstorms on both days. Highs are forecast to be in the upper 80s to upper 90s. Again the threat for strong storms and possible moderate to heavy rain/flooding exists so a watchful eye will be needed. && .AVIATION...Conditions are expected to be VFR at all sites. However, thunderstorms on station will be possible at KELY along with outflow winds to 40 knots after 19Z. Winds will be breezy at all sites. && .FIRE WEATHER...A mix of wet and dry afternoon thunderstorms today with erratic wind gusts. The best chance for local heavy showers will be fire zone 425. Storms may produce some rainfall with isolated cores producing heavy showers. Storms will wane this evening and Saturday is expected to be dry. A few build-ups over eastern Nevada, but convective potential is lower. Breezy afternoon conditions over northwest Nevada and along the northern border. Combined with low humidity, elevated fire weather conditions but below critical thresholds. Moisture increase early next week for showers and thunderstorms with potential for wetting rains over eastern Nevada, possibly as early as Monday afternoon. && .LKN WATCHES/WARNINGS/ADVISORIES... None. && 88/85/86/88
