(This evening through next Tuesday) Issued at 148 PM PDT Wed Jul 2 2025 Upper level ridge over the southwestern high plains is continuing to interact with a weakening upper level trough over central California for the next few days. Monsoonal mid level moisture has been transported northward into Nevada thanks to the broad southerly flow created by the two weather features. For Wednesday and Thursday afternoons there will be a 10% to 30% of a mix of wet and dry isolated to scattered thunderstorms for central and northern Nevada. After Friday the upper low will collapse as it shift east, allowing a more northern stream trough to replace it. This will primarily shift the focus for a 15%to 25% chance for storms across northern Nevada for the 4th of July. From Saturday onward the pattern looks to dry back out as high pressure builds across northern Mexico into the Arizonian and New Mexico. This will change the upper flow to a drier SW flow, with any monsoonal moisture shifted well into New Mexico which is more of a typical early July pattern for the Great Basin. Temperatures for the period will continue to cool a bit for Wednesday and Thursday with highs ranging in the mid 80s to mid 90s with lows in the mid 50s to mid 60s. Independence day will be our coolest day of the stretch as high will be in the low 80s to low 90s with lows in the low 50s to low 60s. Saturday as high pressure returns temperatures will climb again back into the low 90s to low 100s by early next week. Winds through the holiday will remain breezy during the afternoons out of the S to SW with speeds of 10 to 20 mph with gusts up to 30mph possible. During the evenings and overnights winds drop to become light and variable. After Saturday, with the upper ridge building in winds will shift out of the WSW at 5 to 15mph with gusts up to 25 MPH possible. FORECAST CONFIDENCE & DEVIATIONS: There is high confidence in the possibility for the development of isolated to scattered coverage of a 10% to 30% chance of a mix of wet and dry thunderstorms this afternoon and Thursday. There is moderate to high confidence a 15% to 25% chance for a mix of isolated dry and wet thunderstorms for northern Nevada on Friday. There is moderate confidence for near critical fire weather conditions over central Nevada with a low confidence of near critical fire weather conditions over portions of Humboldt, and western Elko Counties. The main deviation from the previous forecast was to increase POPs over northern and north central Nevada to better capture the current thunderstorm development trends over the region and to increase POPs for Thursday and Friday as model trend are reflective of higher storm chances. && .AVIATION... (18Z TAFS) VFR conditions expected to be the dominant category at all terminals, however blowing dust from thunderstorm downdrafts may bring reduced visibility. Breezy southerly/southwesterly winds this afternoon at 10-15 kts, gusts up to 20-25 kts at all terminals, expected to last into the evening. High based thunderstorms over KEKO, KBAM, KELY, KENV, and KTPH continue this afternoon, dissipating during the evening. VCTS expected at KEKO and KELY. AMD NOT SKED for KELY due to visibility sensor. && .FIRE WEATHER... Elevated fire weather conditions continue this afternoon as monsoonal moisture enhances isolated dry thunderstorm conditions across central and northern Nevada along with high daytime winds and low RH values. Tomorrow, conditions look to be the same with isolated dry thunderstorms starting from northern Nevada, elevated winds and low RH. Next weather system Friday bring critical chances of fire weather with high winds and low RH for zones NV425, NV426, and NV427 for the afternoon. && .LKN Watches/Warnings/Advisories...
