Area Forecast Discussion National Weather Service Las Vegas NV 908 PM PDT Thu Apr 2 2020
SYNOPSIS. Breezy to locally windy conditions will continue over the weekend with potential for some strong winds on Sunday across portions of the area. An area of low pressure will slowly move south down the California coast early next week with the low finally moving inland during the second half of the week for an extended period of wet and cooler weather.
UPDATE. No updates are needed this evening with clear skies and generally light winds expected across the region overnight.
PREV DISCUSSION. /issued at 245 PM PDT Thu Apr 2 2020/
SHORT TERM. through Saturday.
There has been a notable decrease in north wind speeds since the morning update. Now seeing most peak wind gusts at or less than 30 mph. The winds will continue to relax overnight as and Friday as the broad trough over the northern Great Basin/northern Rockies weakens. Much cooler this afternoon with 2 pm temperatures running 7-15 degrees below Wednesday. There will only be a minor jump in temperatures Friday, back closer to seasonal normal.
Afternoon southwest breezes along with warmer temperatures return Saturday as the next trough takes shape over the Pacific Northwest. Southwest wind gusts should peak between 20-30 mph Saturday afternoon and evening.
LONG TERM. Sunday through Thursday.
Longwave pattern across the eastern Pacific/western states transitions back into an Omega Block. This was the longwave pattern for much of March that produced Las Vegas's 3rd wettest March.
The closed low from the Pacific Northwest will slowly work south down the California coast Sunday-Tuesday. With this southward motion the main precipitation bands will impact California. For us, that means the southern Sierra Nevada and the rest of Inyo County, as well as the western Mojave Desert of San Bernardino County. Some of our neighbors to the west and north are issuing Winter Storm Watches for the northern and central Sierra. It's a bit too early for us as I'm not looking for heavy snow potential until Sunday night into Monday. Precipitation chances do spread eastward out of California into Nevada and northwest Arizona later Monday into Tuesday. Based on the latest guidance those precipitation totals will be on the lighter side.
By Wednesday and Thursday upper low finally starts its slow movement inland. This is when the details get a bit more murky. Some deterministic guidance suggests more organized bands of showers; possible thunderstorms setting up over southeast Nevada, eastern San Bernardino and Mohave Counties. Again, that is Day 6 and 7 so details will likely change.
AVIATION. For McCarran . Winds will continue to ease up through the rest of this afternoon and tonight. The direction should favor a north-northeast direction through much of the evening before becoming more westerly. On Friday, light winds in the morning will become easterly in the afternoon with speeds 8 kts or less. Mostly clear skies are expected.
For the rest of southern Nevada, northwest Arizona and southeast California . Winds will continue to weaken this evening before becoming typical diurnal direction and speeds overnight. A westerly push of winds will spread across the western Mojave Desert Friday afternoon with gusts to 25 kts by late afternoon. Within the Colorado River Valley, north winds in the morning will becoming southerly during the afternoon. Mostly clear skies are expected.
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.
