Area Forecast Discussion National Weather Service Las Vegas NV 303 AM PDT Mon Aug 10 2020

SYNOPSIS. Expect hot, dry and breezy conditions through much of the upcoming week with temperatures expected to be hottest at weeks end. Without any significant precipitation on the horizon, the main concern will be elevated wildfire spread risk along with continued mid-summer heat. By late week into the weekend, an increase in heat may be in store that could result in a higher risk of heat related impacts.

SHORT TERM. today and Tuesday.

Quiet weather is expected across the region through Tuesday with temperatures forecast to be slightly above normal. Skies will be generally clear except for afternoon buildups over the Sierra where a small chance of a shower or isolated thunderstorm is possible. Hazy conditions will continue across parts of the area due to smoke from the Apple fire but surface visibility reductions are not anticipated. Afternoon breezes are likely today and Tuesday with gusts 20-30 mph over the southeast CWA today and more widespread gusts of 20-25 mph on Tuesday. Moisture is forecast to increase to our south as Tropical Storm Elida, currently south of Baja, strengthens to a hurricane and moves WNW across open waters. Precipitable water trends show this system sending moisture northward into northwestern Mexico and southwestern Arizona through Tuesday.

LONG TERM. Wednesday through the Weekend. Agree in a large part with the day shifts discussion on the pros and cons of the long term period as it pertains to moisture increase and the implications for convection late week.

While the overall outlook is relatively unchanged in the 00Z model suite, it does appear that two things are increasing in confidence: a period of slowly increasing PWAT values across the southern third of the CWA and a building subtropical ridge positioning over the Great Basin by the weekend. While the previous AFD did a thorough job of what uncertainties exist with this synoptic set up and its implications for PoPs, the more obvious signal this will flag is increased heat risk over the weekend and into next week.

A close examination of the Day 5-7 12Z ensemble suite shows further increased confidence in this sub tropical high inching farther west by the weekend, strengthening, and eventually settling over the Colorado River Valley on Sunday. Nearly 40% of the total 90 ensemble members of the EC/GEFS/CMC are suggesting a more amplified ridge than the mean, with significant contributions from all three and the EC leading that solution. 12z ECELAS reflects the increase above 110 degrees for KLAS and would not be surprised to see that value increase further if trends hold. Also of note is the Min Ts again increasing into the mid to upper 80s potentially. Extrapolating this to heat risk, this safely raises the category to major for the LV Valley, Co River Valley, and southern Mohave County. Thus, very soon the discussion for Excessive Heat Watches will likely be needed, should these model trends continue.

FIRE WEATHER. Hot and dry conditions persist with elevated fire conditions for the region through much of the upcoming week. Winds across Mohave County could approach critical thresholds both this afternoon and Tuesday afternoon. With the brief and isolated nature of the wind forecast at the moment, no fire hazard products were issued.

For northwest Arizona . Afternoon breezes will increase again today and Tuesday, leading to elevated and near-critical conditions as afternoon humidity drops near the single digits with poor overnight recovery.

For the southern Great Basin . Afternoon cumulus buildups will increase a little bit each afternoon through midweek, with some isolated dry lightning concerns in northern fringes of zones 460 and 461 by Tuesday.

AVIATION. For McCarran . Light and variable winds early this morning will become easterly and should gradually lead to enhanced southeast winds over 10 knots mid-afternoon through early evening. A few gusts to 20 knots are possible. Typical light south-southwest winds will develop around sunset and continue overnight into early Tuesday morning under a clear sky. For the rest of southern Nevada, northwest Arizona and southeast California . No significant weather is expected across the region today and tonight. Winds at TAF sites gusting 15 to 20 knots will be common in the afternoon hours otherwise speeds will generally be less than 10 knots under mostly clear skies. Areas of smoke and haze will linger, especially southeast California due to ongoing wildfires.

SPOTTER INFORMATION STATEMENT. Spotters are encouraged to report any significant weather or impacts according to standard operating procedures.

SHORT TERM . Salmen LONG TERM . TB3 AVIATION . Adair

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.
