Area Forecast Discussion National Weather Service Las Vegas NV 917 AM PDT Sun Sep 27 2020

SYNOPSIS. Warm weather will continue today before an incoming dry cold front delivers gusty north winds tonight and Monday along with temperature briefly dropping several degrees. Temperatures will quickly rebound by midweek with dry conditions persisting into next weekend as a strong ridge of high pressure rebuilds over the region.

UPDATE. Main concern is the potential for critical fire weather conditions with the increased winds accompanying the weak frontal passage expected later tonight into tomorrow. Overall, guidance continues to be underwhelming in terms of expected wind maxima. Decided to wait until the newest guidance comes in before making a decision on whether to upgrade the Fire Weather Watch or pull it . stay tuned.

PREV DISCUSSION. /issued at 304 AM PDT Sun Sep 27 2020/

SHORT TERM. Today through Monday.

North winds generally gusting 15-25 mph have already developed across Inyo County and south central Nevada early this morning in response to the increasing pressure gradient over the Great Basin associated with the broad trough digging over the Intermountain Region and central states. North-northeast winds will continue to increase today and especially tonight through Monday morning as the system digs and increases the pressure gradient across our region. However, impacts will be minor as gusts will generally be in the 25- 35 mph for most of the region. The latest high res models indicate enhanced speeds on the mountains and higher terrain as well as the Colorado River Valley and the latest winds grids are a blend of the NBM and ARW 4km. Gusts may approach 40 mph near Laughlin-Bullhead City early Monday morning due to terrain-induced gap flow but most of Lake Mead and Lake Mohave will generally see speeds of 10-20 mph and some gusts to 30 mph late tonight through early Monday afternoon. No wind headlines are planned besides fire weather concerns. Temperatures will be down a few degrees today as heights lower followed by a more noticeable drop tonight and Monday with the north-northeast winds. Highs of 90-95 degrees Monday for most over the desert zones will be close to seasonal normals.

LONG TERM. Tuesday through Saturday.

A large ridge of high pressure will build across the Western U.S. Tuesday onward. This will initiate a warming trend with near normal temps Tuesday rising to 5-10 degrees above seasonal normals Wednesday into the weekend. Winds will also be lighter underneath the ridge with little in the way of cloud cover.

FIRE WEATHER. An incoming cold front will bring gusty north winds and dry conditions to the region tonight through Monday. The Colorado River Valley will see the best potential for RH values less than 15 percent and gusts around 35 mph especially over the area from Laughlin and Bullhead City to Mohave Valley. A Fire Weather Watch has been posted for Monday morning through the afternoon.

AVIATION. For McCarran . Northeasterly winds developing later this morning may decouple and go light and variable overnight tonight before another reinforcing shot of northerly winds arrives Monday. Mainly blue skies expected, with increasing potential for low-level wind shear and clear-air turbulence later Sunday into Monday.

For the rest of southern Nevada, northwest Arizona and southeast California . North to northeasterly winds will take over much of the region today, strongest in the usual favored areas such as the Colorado River Valley. Another, stronger, shot of northerly winds expected by Monday. Generally blue skies outside a few high, thin clouds with low-level wind shear and clear-air turbulence hazards increasing into Monday.

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