Synopsis...dry and seasonable weather can be expected through
the week followed by a cooling trend late in the weekend. Breezy
conditions will develop Thursday then again Saturday night and
Sunday as fast moving weather systems brush the region.
Discussion...this evening through next Monday.
In general there is no significant weather impacts expected over
the course of the upcoming week. A weak system, currently moving
over the region, has funneled a shallow layer of moisture up the
Colorado River today leading to flat cumulus fields across southern
Mohave County. Behind this system ridging will build in from the
east Pacific and linger overhead through Wednesday morning. This
will increase temperatures 3-6 degrees above normal by Tuesday,
which will continue through at least Wednesday.
The next weather system is progged to move across the west Thursday.
As it swings toward the intermountain west, gradient winds will
increase Wednesday and Thursday, with the strongest winds expected
Thursday. Overall, there has been little change in the expected
winds, with gusts peaking around 30-35 miles per hour Thursday afternoon and
evening. Temps will drop over the weekend in response to an
attendant cold front pushing southward Thursday night/Friday morning.
Aviation...for McCarran...no significant impacts expected through
the next 30 hours for klas. A benign weather pattern will allow for
traditional diurnal wind patterns to govern the valley today. Thus,
variable but generally easterly light winds below 8 kts can be
expected through the afternoon before a return to west-southwesterly
light winds tonight. The few high cirrus this morning will push east
leaving sky clear to prevail through at least mid day tomorrow if not
For the rest of southern Nevada, northwest Arizona and southeast
California...no significant impacts for all terminals through the
next 24 hours. Only mentionable wind is minor gust potential due to
a shift to north winds tomorrow late morning into the afternoon for
keed/kifp, but gust potential will top out at 10-15 kts at best. Few
clouds at 25kft but VFR throughout.
