Area Forecast Discussion National Weather Service Reno NV 214 PM PDT Sun Jul 5 2020

SYNOPSIS.

Average summer temperatures will continue through Monday before a very slight cool down for mid week, then temperatures warm to slightly above average by next weekend. Afternoon and evening breezes are expected again this afternoon with a noticeable increase for Monday afternoon which will bring heightened fire weather concerns. No appreciable precipitation is forecast over the next week.

DISCUSSION.

For this afternoon/evening, with a trough over the east Pacific Ocean moving over the West, the Zephyr is slightly enhanced by an uptick in winds aloft. Expect breezes with peak gusts in the 25 mph to around 30 mph range. These gusts, though short of critical fire weather levels, can still cause fires to grow in size and intensity so please take care to prevent wildfires.

For tomorrow afternoon/evening, as the trough axis moves across northern CA/NV, red flag warnings and lake wind advisories are in effect. Expect peak gusts generally in the 25-40 mph range. This raises concerns for recreation areas, lake conditions, and high profile vehicles. Expect choppy waves for area lakes likely resulting in unsafe conditions especially for small watercraft, like kayaks and paddleboards. Consider postponing boating activities on area lakes until a day with less wind. For discussion of the fire threat, please see the Fire Weather section below.

For the rest of next week, expect a slow warming trend starting Wednesday as a high pressure system over the 4-corners builds westward. Very dry conditions persist over the east Sierra/ northwest CA/ western NV and no thunderstorms are currently forecast through Saturday. However, subtle changes in the flow between a Pacific Northwest Low and the 4-corners High could result in moisture transport (southerly flow) over the area which could raise the chances for thunderstorms by next weekend. JCM

AVIATION.

Widespread VFR conditions continue into the week ahead. Breezy afternoon and evening winds will continue through around 03z this evening with peak gusts generally in the 20-30 kts range. Winds tomorrow afternoon will be a bit stronger than today with peak gusts up to 35 kts possible from about 18-04z. There is also a small chance (less than 10%) for thunderstorms to develop north of Susanville late Monday afternoon. JCM

FIRE WEATHER.

Only significant change to the fire weather forecast today was to upgrade the remaining Sierra and northeast California zones to Red Flag Warnings for Monday. Those areas are lower confidence for seeing widespread winds in excess of 30 mph, but exposed midslopes and ridges could see an extended period of critical to near critical conditions with very low humidities. The highest confidence for winds remains in western Nevada where gusts of 35-40 mph are likely.

The very dry airmass started to move into the region this morning with relative humidities dropping into the teens and 20s along the Sierra ridges. Many areas will likely see poor humidity recoveries tonight, especially along the midslopes and ridges. Minimum humidities are expected to be very low on Monday, even for our normally dry desert environment, as that dry air works into the region. Areas in western Nevada will likely see humidities in the single digits to low teens, with teens possible in the Sierra and northeast California tomorrow afternoon.

Lighter afternoon winds are expected on Tuesday with gusts returning to the 20-25 mph range. No precipitation is in the forecast with near average temperatures and winds expected for the rest of the week. -Zach

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
