Area Forecast Discussion National Weather Service Las Vegas NV 154 AM PST Mon Dec 16 2019
SYNOPSIS. High pressure will bring quiet weather through Tuesday except for gusty north winds down the Colorado River Valley. A weak storm will pass by Wednesday with increased cloud cover, then high pressure will return Thursday through Saturday. Stronger storm systems could bring wet periods from Sunday through Christmas.
DISCUSSION. Aside from cirrus over SE CA, skies were clear over our CWA early this morning. Winds were light, and temperatures were seasonably chilly. Only impactful weather today and tomorrow will be gusty north winds down the Colorado River Valley. As noted by previous shift, conditions will be very close to Lake Wind Advisory criteria today, and perhaps Tuesday as well. Tricky forecast in that different pieces of model guidance not only give different answers of whether or not Advisory criteria will be reached today, but also whether today or Tuesday will see the stronger winds. Will hit it on social media today, and let what happens today serve as another piece of guidance to help make a decision for tomorrow. As also noted by previous shift, the storm system reaching the West Coast Tuesday night and crossing our area Wednesday continues to look weaker with each successive model run. Expect no precip outside of the Sierra, and little or none there. The storm will reverse the pressure gradients helping to drive the northerly winds down the Colorado River Valley, thus shutting them down after Tuesday. High pressure noses back in Thursday, bringing more dry weather through Saturday. By that time, the next storm system, which looks much more impressive (at least for now) than the one on Wednesday, will be nearing the West Coast. As is typical, there is some model spread with regards to the timing and strength of this storm, as well as whether there will be one or more additional storms hot on its heels. The main message is dry weather through Saturday, with temperatures below normal early in the week rising to near or slightly above normal at the end of the week, with a chance of a wet period next week.
AVIATION. The main forecast concerns today center around the breezy northerly winds. An easterly component will increase today, though how northeasterly vs northerly the winds will go remains difficult to pin down. Winds calm down once again after sunset, with another round of northeast winds possible for Tuesday.
For the rest of southern Nevada, northwest Arizona and southeast California . Main weather concern through the period is northerly winds across the region. The strongest will be in favored areas down the Colorado River Valley, with a more northeasterly direction across the Mojave Desert, including KDAG. Speeds diminish significantly with sunset, and winds favoring drainage trends expected tonight.
SPOTTER INFORMATION STATEMENT. Spotters are encouraged to report any significant weather or impacts according to standard operating procedures.

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.
