National Weather Service Las Vegas NV
111 PM PDT Fri Apr 19 2024

.SYNOPSIS...-- Changed Discussion --Expect the weather will have its ups and downs over
the course of the next week with the pattern transitioning from
high pressure ridging followed by low pressure troughing. This
will result in well above normal temperatures continuing through
Tuesday then cooling back to seasonal levels late next week. In
addition, there will be gusty winds for much of next week and
a chance for showers late next week.-- End Changed Discussion --

.DISCUSSION...

-- Changed Discussion --A weak disturbance over the area today will move east tonight with
enhanced southwest winds across the deserts of San Bernardino
County this evening. No significant winds are expected with gusts
generally in the 20-30 mph range. high pressure ridging bringing
us well above normal temperatures and widespread minor and
localized moderate heat risk over the weekend. The gusts will
become more localized by late evening becoming light overnight.

High pressure ridging will bring us well above normal temperatures
over the weekend into early next week with high temperatures
expected to reach and possibly eclipse 90 degrees in Las Vegas and
100 degrees in Death Valley. The unseasonably warm conditions
across the region will raise heat risk into the minor-moderate
category, especially by Sunday and Monday. Minor heat risk levels
will be more widespread while moderate levels will be more
localized to the lower elevation desert areas such as Death Valley
and the Colorado River Valley. At this point, no heat products
are in effect or planned due to the warmer, above normal
conditions we have already experienced the past few days and more
importantly, the extent or upper limit of temperatures that are
forecast. Record highs through Monday are generally around 5-7
degrees above the forecasted high temperatures.

Wednesday through Friday...The weather pattern will become more
active within both the northern and southern jet streams with low
pressure systems potentially bringing impacts to the much of the
western CONUS. Forecast uncertainty is generally high which
currently limits pinning down the extent of impacts that can be
expected.-- End Changed Discussion --
