Area Forecast Discussion
National Weather Service Las Vegas NV
220 AM PDT Mon May 31 2021

.SYNOPSIS...
Dry conditions and an upward trend in temperatures can be expected
through at least Thursday. Hottest days will be Wednesday and
Thursday with highs reaching within a couple degrees of daily
records for some areas. Heat impacts will be the main concern as
heat risk increases to "high" for locations including Las Vegas by
Thursday. Gusty winds will begin Thursday and continue into the
weekend.

&&

.SHORT TERM...Today and Tomorrow.
A dry and hot day Memorial Day will set the stage for the rest of
the week with highs approaching the century mark for Las Vegas and
higher for the lower desert valleys. The big question mark for many
thermometer watches will be if Memorial Day will also be the first
100 degree day of the year, which would also score us a 100 for the
month of May. The NBM deterministic is sticking with 99 officially
with some bias corrected guidance pushing it to 100. Of note, the
01Z NBM probabilistic guidance suggests a 67% chance of 100 today
despite its 99 degree official forecast. With some high clouds
moving in this afternoon, it may just be enough to keep that 100 at
bay. So we have to wonder...it's going to be June, or it's gonna be
May?

We should safely get there Tuesday as H5 heights increase almost 7
decameters over Nevada due to a quickly building ridge. This will be
the ridge of focus for the rest of the week that resulted in our
issuance of the Excessive Heat Watch Thursday.

.LONG TERM...Wednesday through Sunday.

The forecast for this time frame has not changed much with a high
amplitude ridge forecast over the western states on Wednesday that
slowly transitions east on Thursday and Friday as troughing moves
over the PacNW. Wednesday and Thursday are still forecast to be the
hottest days of the week with temperatures warming to within a few
degrees of records. New data from the NBM this evening had only
slight changes and keeps high temperatures about 10 degrees above
normal both days. An Excessive Heat Watch is in effect for both days
for areas where high Heat Risk is forecast including Death Valley
National Park and surrounding low elevation locations, the southern
parts of Nye County including Pahrump, the Las Vegas Valley and
Mesquite area in Clark County, and the Colorado River Valley from
Lake Mead south to the Laughlin/Bullhead City area. Elsewhere,
widespread moderate heat risk is expected with the exception of the
higher elevations.

After Thursday when the high pressure ridge is gone and troughing is
present to our north, temperatures are expected to become less hot
but still above normal for next weekend. With the troughing over the
PacNW on Friday dropping south into the Great Basin, we could see
