Fxus65 krev 202241 afdrev area forecast discussion national weather service reno nv 341 pm pdt Fri sep 20 2019 Synopsis Temperatures will begin to warm today through Sunday before another cold front brings gusty winds, shower chances, and a slight cool down into Monday. A warmup will occur Tuesday-Thursday before another cooler weather system moves into the region late next week. Short term The main change to the inherited forecast was to slightly slow down the forward progression of the cold front Sunday into Monday. Freezing fog was also added for the sierra valleys north of lake tahoe. The big weather story is the variable weather expected in the next 7-10 days. Temperatures: after some chilly weather this morning, we will begin to warm up going into the weekend. Expect mid to upper 70s in western nv and mid-60s to low 70s for sierra valleys Saturday and Sunday. A slight cool down will occur Monday as a weak cold front passes across our area. Highs will then warm to nearly 4-7 degrees above normal by Wednesday. This translates to low 80s in western nv and 70s for sierra valleys on Tuesday. Winds: light winds are expected this evening through Saturday, before the pressure gradient tightens ahead of an approaching cold front Sunday. Winds are forecast to gust as high as 30 mph for most areas Sunday afternoon ahead along cold front. Localized travel and recreation impacts are possible with this system. Winds Monday behind the front will be breezy out of the north northwest, however minimal impacts are expected. Precipitation: dry conditions will prevail Saturday and most of Sunday. Showers are possible Sunday afternoon into Monday. Best chances will be north of interstate 80 to the oregon border. Some higher mountain snow showers are possible, but confidence is low. -johnston

Long term Tuesday through next weekend... well, if you've liked the roller coaster of fall weather the last few weeks, you're going to like the long term forecast. If you prefer warmer and drier weather only, mid week is right up your alley... And you may want to stop reading at the end of the next paragraph. Warmer and drier conditions are expected for the the middle of next week as high pressure builds over the eastern pacific. Temperatures are expected to rebound to the low to mid 80s in the valleys and mid 70s in the sierra, about 5 degrees above average. For the long range forecast, ensemble models are good agreement that another trough will move into the region during the second half of next week, likely lasting into the weekend. This will bring increasing chances for additional precipitation along with much colder temperatures back to the region. By next weekend, daytime high temperatures could be back down to 10-15+ degrees below normal. -zach Aviation Mostly clear skies expected for tonight with areas of freezing fog in the sierra valleys, including trk with lifr conditions. Otherwise,VFR conditions continue through the weekend. Winds will increase on Sunday afternoon ahead of another cold front moving through the region. These increasing winds will bring some mountain wave turbulence and wind gusts at the terminals up to 25-30kts. -hoon Rev watches warnings advisories Nv... None. Ca... None.

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.
