Area Forecast Discussion
National Weather Service Las Vegas NV
1001 AM PDT Tue Jul 6 2021

.SYNOPSIS...Temperatures will climb well above normal Wednesday
into early next week as a strong area of high pressure builds
overhead. Southeast flow Thursday and Friday will bring a brief
period of increasing moisture, mainly to northwest Arizona and the
lower Colorado River Valley, though hot conditions will continue.
&&

.UPDATE...We're on track to be a few degrees warmer today than
yesterday across the region as the ridge meanders overhead.
Besides some patchy mid-level clouds across the eastern half of
the CWA, expect dry and mostly clear skies today. No forecast
updates were necessary this morning.

.PREV DISCUSSION... /issued at 218 AM PDT Tue Jul 6 2021/

.SHORT TERM...Today through Wednesday.

Temperatures will continue their upward trend today and Wednesday
adding another 2-3 degrees each day which will kick off another
prolonged period of excessive heat extending into early next week.
Forecast highs exceed record values for Bishop beginning Wednesday
while other sites such as Las Vegas and Death Valley will be within
2-3 degrees of records. No changes are planned to the Excessive Heat
Watch going into effect Wednesday through Monday.

Some mid level clouds could be seen on satellite loops being drawn
up from southwest and central Arizona in weak southeast flow. There
are no concerns of any convection today or Wednesday as low levels
remain dry with dewpoints in the 30s and the air mass remains quite
stable with a capping layer above 500 mb.

.LONG TERM...Thursday through next Monday.

On Thursday, high pressure will be centered east; near the Four
Corners region. This will open the door for an intrusion of moisture
as ensembles indicate precipitable water values in excess of 1 inch
returning into southern Mohave County, up the Colorado River Valley
and San Bernardino County deserts. This will help temper the
temperatures slightly and potentially introduce the possibility of a
shower/thunderstorm back into southern Mohave and eastern San
Bernardino County though the probability is currently less than 10
percent so there is no mention in the weather grids.

Friday-Monday: High pressure center shifts back west over Nevada and
the Mojave Desert. Temperatures for the weekend into early next week
will be at their hottest. An Excessive Heat Watch has already been
issued for another long duration heat event. The current forecast is
dry but there will be some mid-level moisture circulating under the
ridge that could potentially pop a storm along the southern Sierra
crest over the weekend.
