Marine Weather and Tides
8/26/2020 The 7 day forecast is taking about 5 seconds to load but it will eventually load. NOAA is still working on it.
8/18/2020 NOAA continues to have trouble. Wind guest will occasionally be left off graphs. I am working with NOAA to resolve the issue.
12/16/2019 NOAA is having trouble with requests that include wind gusts. I am posting graphs without wind gusts until it gets fixed.
10/9/2019 Updated the Marine Zones.
9/4/2019 Fixed the weather maps due to NOAA moving them.
7/25/2019 New feature in the Airports section gives a link to 5 minute updates for data reports.

SYNOPSIS. Dry conditions and above normal temperatures will persist for the next week. Smoky and hazy skies will also continue, with the worst conditions likely in the Owens Valley. Breezy conditions this afternoon and Friday afternoon will keep fire danger elevated before winds settle down over the weekend.
SHORT TERM. through Friday. Satellite loop showed no water or ice clouds over our CWA early this morning, although plenty of smoke and haze remained in place. Evening shift did some work on the sky grids with a recently introduced tool which incorporates smoke, and these grids looked good, so made no changes. Low pressure coming onshore in the Pacific Northwest early this morning will track east along the Canadian border through Friday, with only breezy afternoon winds for our region. These winds will remain well below Red Flag thresholds, although exceptionally dry fuels will keep fire danger elevated. Temperatures will remain well above late September normals, with KLAS likely to see the 96th 100F day of the year, which would trail only the 100 such days observed in 1947.
LONG TERM. Weekend through Mid-Week Next Week. Only minor change in the long range forecast is a reversal in the Max T trends moving into next week and into the middle of the week. Initially was expecting temperatures to begin to climb or at least stay consistent but both ECE/MEX output shows an overall decrease in top end temperatures for next week. After interrogating ensemble clusters this looks like it may be due to a trend of deepening the mid-CONUS low and tempering H5 heights somewhat across the eastern half of the CWA. This doesn't deter the prospect of a stout, amplified ridge for the western CONUS, but this just may not be as broad as originally thought. Ended up blending the previous forecast values with the latest NBM highs to compromise since there is still considerable mean variance with this particular feature and its positioning.
AVIATION. For McCarran . Light winds becoming southeast to south late-morning, shifting to south to southwest in the afternoon with gusts increasing to around 20 kts by late in the afternoon/evening. Some light turbulence below 15 Kft and weak low-level wind shear around 10kts possible most of the day before surface winds switch to southwest. Areas of smoke will linger with no impactful reductions in surface visibility expected.
For the rest of southern Nevada, northwest Arizona and southeast California . South to southwest winds expected to increase in the afternoon with smoke staying aloft outside of the Owens Valley. Visibilities at KBIH will continue to be impacted with periods of instrument conditions likely.
SPOTTER INFORMATION STATEMENT. Spotters are encouraged to report any significant weather or impacts according to standard operating procedures.
