Area Discussion for - Reno, NV

Fxus65 krev 252135 afdrev area forecast discussion national weather service reno nv 235 pm pdt Sun aug 25 2019 Synopsis Temperatures will be well above normal through the upcoming week, with the warmest conditions most likely Tuesday. Expect breezy conditions through this evening, especially north of highway 50. A few thunderstorms are possible near the sierra crest on Tuesday, with another chance for thunderstorms on Wednesday. Otherwise, dry conditions are likely to prevail through the week. Short term Changes in the short term forecast include: * adding a slight chance of thunder near the sierra crest Tuesday afternoon. * expanding thunderstorm chances to include more portions of northwest-west central nv and far northeast ca Wednesday afternoon-evening. Meanwhile, breezy conditions will continue through this evening in the wake of a trough moving across the northern rockies. Gusts up to 35 mph are expected in some areas north of us-50, with humidity values 15-20%, resulting in localized critical conditions for fire weather (as was evident yesterday with two new fire starts in lassen county), but conditions improving during the evening. Very warm and dry conditions will prevail Monday-Tuesday with lighter winds as a ridge of high pressure builds over the great basin. Additional heating on Tuesday with highs near 100 degrees in some lower elevations will lead to increased afternoon cumulus. Some of the latest guidance is showing a bit more instability near the sierra, which may just be sufficient for building a couple of brief cells along the crest late in the day. Wednesday continues to show some potential for isolated showers and thunderstorms as a weak upper disturbance combines with residual moisture from tropical storm ivo. Increasing mid level moisture cloud cover developing Wednesday morning, generally south of us-50 and east of us-95, has a slight possibility of producing a few lightning strikes, but confidence isn't sufficient enough to include thunder yet. By Wednesday afternoon, isolated thunderstorm chances increase as the disturbance pushes northward through the region. Currently the more favored areas include far northeast ca and northwest nv, and also from mono-mineral counties northward across the basin and range mainly east of us-95. The main effects of these storms are likely to be strong outflow gusts of 40+ mph. A few locations could receive short periods of heavy rain, but the potential is there for new lightning fire starts as the most storms should move at a moderate pace (around 15-20 mph). Mjd

Long term Thursday through labor day... not many changes to the inherited, long term forecast this cycle. Chances for thunderstorms Thursday afternoon evening have been taken out of the forecast at this time as new guidance suggests less moisture and more stable conditions. The residual moisture from tropical storm ivo looks to shift eastward into central eastern nevada as the center of the high pressure ridge over the southwest u.S. Rotates towards the west over southern california. Along with drier air in the mid to upper levels and relatively low pws, forecast soundings indicate stable conditions with little to no instability and a hint of a capping inversion in the afternoon. Besides for some possible cumulus build-ups along the sierra and down into mono county on Thursday, the rest of the forecast through labor day looks high and dry with typical afternoon breezes and above average temperatures. The deterministic as well as the ensemble model guidance shows a strengthening ridge over the western half of the country lasting through at least labor day. High and low temperatures are forecast to stay above normal during this time... 10-15 degrees above normal. As we head into september (the start of meteorological autumn) the averages for high and low temps begin to drop off a degree every 3-4 days. With high temps forecast in the mid to upper 90s for western nevada to start next week, meteorological autumn looks to start out quite toasty. Heightened fire weather concerns look possible Thursday onward with dry conditions at all levels in the atmosphere, hot temperatures and breezy west winds each afternoon-evening. -laguardia Aviation Clear skies andVFR conditions will persist for the rest of today and into Monday as high pressure dominates. Expect wnw winds 15-25 kts for all area terminals (ssw for ktvl) mainly north of us-50 for this afternoon likely to taper off around 03z-05z. Weaker winds are forecast for Monday from more of a northerly direction. Chances for thunderstorms begin on Tuesday afternoon with development along the sierra in mono county. Coverage increases across southern mono, mineral and churchill counties as well as some slight chances for northern washoe county on Wednesday afternoon evening. -laguardia Rev watches warnings advisories Nv... None. Ca... None. For more information from the national weather service visit... http: weather.Gov reno

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 numerious 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.
