Area Forecast Discussion National Weather Service Elko NV 204 PM PDT Mon Aug 7 2017 .SYNOPSIS...Showers and thunderstorms expected over the coming days. Heavy rain and flash flooding possible across eastern and central Nevada through this evening. Warming and drying pattern returns late work week, but thunderstorm chances will remain across the north. && .SHORT TERM...Today through Wednesday. Sunny skies earlier today coupled with monsoonal moisture across nevada and a more northward jet is leading to a more wide spread area of convection. That is currently leading to a more uniform coverage of thunderstorms that are currently impacting the CWA. PWAT values 0.80 to 1.00 and continued slow storm motion will again lead to potential heavy downpours and an elevated risk of flash flooding over central/eastern NV, with the best potential over White Pine county. Tomorrow, drier air begins to infiltrate central NV, but with moisture and upper-level dynamics in place, still expect scattered thunderstorms across northern NV with more isolated coverage across the central. Cooler temperatures still remain but a warming trend is starting expect highs in the 80s and lows in the 50s. .LONG TERM...Wednesday night through next Monday. Models are generally in good agreement through the long term period with lingering moisture trapped under a weakening ridge, gradually being replaced by drier air that will push in from the southwest. Some isolated to scattered showers and thunderstorms will linger across northern portions of the CWA Thursday and Friday. There will also be some warming high temperatures later in the work week with highs generally in the mid 90s. Drier air takes over most of western and central portions of the CWA on Saturday, however there will also be another push of moist air pushing up into far east- central NV. Continued the trend of increasing pops and TS coverage Saturday and Sunday afternoons, with a slight chance of lingering TS over far eastern NV into Monday. && .AVIATION...Showers and thunderstorms have developed across much of central and portions of northern NV this afternoon. Best chances for impacts at or near terminals still looks like KELY and possibly KEKO through this evening, due to moderate to locally heavy rains in TS. Storms die out later this evening. Air mass should be more stable on Tuesday, with much less of a threat of TS. && .FIRE WEATHER...Today, moisture and instability overruns all of the zones and expecting scattered wet thunderstorms. Drier air will begin to push into central NV zones on Tuesday, but still expecting scattered wet storms across northern zones with an isolated mix of wet/dry storms across the central. Gusty erratic outflow winds will be possible both today and tomorrow. Nighttime RH recoveries remain very high with a lot of areas being over 60% to some areas being over 80% && .HYDROLOGY...Monsoonal moisture continues to be drawn north across NV today, resulting in scattered showers and thunderstorms across all northern/central NV. PWAT values nearing an inch at times and slow storm motion could likely lead to prolonged heavy downpours and could create areas of flash flooding. Flash flood watch remains in effect for central and parts of northeast NV through tonight. Greatest potential for flooding remains over east-central NV, but further north, the flash flooding threat will still exist, but on a lesser scale, due numerous recent large burn scars that will be susceptible to heavy rainfall. && .LKN WATCHES/WARNINGS/ADVISORIES... Flash Flood Watch through late tonight for Northeastern Nye County-Northwestern Nye County-Ruby Mountains/East Humboldt Range-South Central Elko County-Southeastern Elko County- Southern Lander County and Southern Eureka County-Southwestern Elko County-White Pine County. && 99/96/96/99
