Area Forecast Discussion National Weather Service Reno NV 229 AM PDT Mon Aug 3 2020

SYNOPSIS.

Warm and dry conditions with gusty winds again this afternoon and evening. A gradual cool down to near normal will occur through the week with chances for thunderstorms returning the middle into the end of the week.

DISCUSSION.

The air mass remains extremely dry today (0.18 inches precipitable water yesterday afternoon is near record lows for August based on the history of measurements taken by weather balloons since 1956). Humidity "recoveries" were very poor again this morning and afternoon relative humidities will be in the single digits this afternoon. This dry air along with westerly gusts 25-35 mph this afternoon will create pockets of enhanced fire danger this afternoon and evening (similar to yesterday). These conditions are not widespread or long enough in duration for a warning, but be especially careful not to cause a spark.

Smoke from the Stump, Red Salmon Complex and North Fires will create haze for portions of northeast CA and northwest NV this morning especially in Lassen and Plumas Counties, and likely also in the Tahoe Basin and Reno/Sparks areas. When westerly breezes kick in this afternoon the haze may clear out somewhat for areas near and south of I-80.

A saggy trough over the West will provide a slight cooling of temperatures starting Wednesday. Atmospheric moisture will slowly increase, with the current forecast calling for afternoon/evening thunderstorms in the Surprise Valley and far northern Washoe County on Wednesday, and for Thursday for portions of Alpine and Mono Counties and north of Portola-Gerlach. With the dry air in place ahead of this, and lack of deep moisture (PWAT values around 0.5"), small rain cores are likely with a definite concern for dry lightning starts. Storm coverage, however, looks to remain isolated. JCM

AVIATION.

The biggest flight weather concern for this period will be some reductions to slant-wise visibility on terminal approach. Smoke from fires in northern California will continue to produce hazy conditions for the next 24 hours, possibly longer if fire activity increases.

Otherwise, typical afternoon breezes can be expected with dry, VFR conditions. The chances of thunderstorms will be Wednesday and Thursday as a trough moves into the region. However, these storms will be isolated and limited to locations north of a Susanville to Gerlach line and along the Sierra/Sierra Front of Alpine and Mono Counties. Boyd/Mittelstadt

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerous of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
