Area Forecast Discussion National Weather Service Las Vegas NV 337 AM PST Sat Jan 25 2020
SYNOPSIS. Dry weather conditions are expected for today with periods of passing high clouds and seasonally warm temperatures. A weak weather system will pass across the region on Sunday; increasing rain and higher elevation snow chances across northern Inyo County and the southern Great Basin as well as creating breezy conditions across the area going into Monday.
DISCUSSION. Through Friday.
A pair of systems will bring mainly wind impacts to the region on Sunday and Wednesday, with above normal temperatures expected for most if not all of the upcoming week.
Quiet weather expected today ahead of the next upper-level trough. By Sunday, the aforementioned trough will swing ashore, move east across California and Nevada, then deepen and dig southward as it passes the region. Some west to southwest wind enhancement in the usual favored corridor is expected with a little lower confidence on widespread post frontal winds later Sunday into Monday. The current track should allow a cold front to traverse the entire CWA, so would lean towards strong frontal winds moving south across the region Sunday evening and night, with lingering north breezes for the entire area on Monday. Only about 5 degrees of cooling is expected from highs on Sunday to Monday, not enough to cut temperatures back to even seasonal normals.
The next upper-level trough which should arrive near Wednesday continues to look more interesting. The Euro has been slowing trending towards the GFS with a deeper and further west system, and is now even a bit further west than the GFS. Thus, agreement has increased on a shortwave coming ashore near the CA-US international border, with much of the energy quickly digging southward across the intermountain west down to the other international border. As is typical of this track, prefrontal winds look fairly minimized, but with a stout cold front with strong frontal and post frontal winds likely for much of the area. While the pattern is a match for at least advisory level winds for the region, guidance does not seem to indicate an attendant sharp cooldown that would support strong winds. Additionally, ensembles still express great uncertainty in timing, which subtracts from overall confidence even more.
By Thursday, ridge of high pressure takes back control of the area, with winds relaxing and temperatures resuming a warming trend through the end of the week, approaching or exceeding 10 degrees above normal by next weekend.
AVIATION. For McCarran . Expect light winds favoring typical diurnal directions to continue through today into Sunday, generally remaining below 6-8 knots. High clouds will continue to stream overhead through the early morning with some clearing by late morning before another round of high and mid level clouds move across southern NV by late afternoon.
For the rest of southern Nevada, northwest Arizona and southeast California . Some breezy north winds are expected again this afternoon down the Colorado River Valley, mainly impacting KIFP with gusts to 15-20 knots. Elsewhere, expect light winds following typical diurnal directions to continue through today. High clouds will continue to stream overhead through the early morning with some clearing by late morning across the Mojave Desert before another round of high and mid level clouds move across the region later this afternoon.
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.
