Area Forecast Discussion National Weather Service Las Vegas NV 745 PM PST Fri Jan 15 2021

SYNOPSIS. High pressure will hold over the region through the weekend in spite of a disturbance which will produce increasing north winds Saturday. The weather pattern finally changes Monday and Tuesday as a low pressure system dives down and spins up over southern California bring chances for light precipitation to southern Nevada and surrounding areas Tuesday and possibly into Wednesday. This will be followed by a potentially stronger Pacific storm system Friday into next weekend.

UPDATE. Next shortwave of interest is currently located over the northern Great Basin and will slide southeastward tonight. Ahead of this feature, some enhanced cirrus is spilling into the region which will traverse our skies from north to south tonight. Overall, the forecast is in good shape with northerly winds picking up tomorrow, particularly across the Colorado River Valley where a wind advisory is in effect.

-Outler-

SHORT TERM. through Sunday night.

We will see increasing north-northeast winds Saturday behind a shortwave dropping quickly from the Pacific Northwest down through Utah into Arizona tonight and early Saturday morning. The strongest winds will be down the lower Colorado River Valley where gusts over 40 mph can be expected from around Katherine Landing to Lake Havasu Saturday morning through the afternoon. A Wind Advisory is in effect for these areas from 8 AM until 5 PM PST Saturday. Gusts of 20-30 mph will be common over much of Lake Mead, especially the Overton Arm and Virgin Basin. The winds will mix the boundary layer and lead to the warmest day of the week for most areas followed by 3-5 degrees of cooling Sunday and fairly light winds except gusts up 30 mph around Laughlin-Bullhead City.

LONG TERM. Monday through Friday.

A significant change in the weather pattern is shaping up for the coming week which will allow multiple low pressure systems to begin affecting our weather. The first low pressure system will spin up as energy diving down from eastern Washington/Oregon merges with a shortwave trough off the SoCal Coast late Monday to form a large closed low which is forecast to be centered near or off the SoCal Coast Tuesday. Widespread gusty north-northeast winds will likely develop across the region Monday into Tuesday then, if the system stays close enough to southern California without pulling too far to the southwest, sufficient moisture and dynamic forcing with the system will produce a favorable setup for chances of light precipitation across much of southern Nevada and areas to the south. The latest NBM grids reflect this with an extensive area of 20-30 percent probability of precip and the 12Z GEFS/ECMWF ensemble means also support this trend. However, it still looks like a general light precipitation event as the system dips southward far enough Tuesday night and Wednesday to reduce precip chances.

However, hope remains for additional chances later in the week as a large low pressure system is forecast to drop down from the northwest along the West Coast especially Friday going into next weekend which should have considerable moisture and a more favorable trajectory for widespread precipitation. Stay tuned.

AVIATION. For McCarran . No operationally significant clouds or weather today. North to northeast winds up to 10 knots expected to develop this afternoon with diurnal southwest winds tonight. Northeast winds are expected to increase late Saturday morning with speeds generally around 8-10 kts.

For the rest of southern Nevada, northwest Arizona and southeast California . Breezy northerly winds will continue in the Colorado River Valley, with gusts 20-30 knots this afternoon with winds generally less than 10 kts elsewhere. Northerly winds will increase down the Colorado River Saturday with winds 25-35 kts. Most other areas will continue to see winds 10 kts or less. No operationally significant clouds or weather today.

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.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
