KEY MESSAGES
* DRY CONDITIONS AND WARMING TEMPERATURES WILL CONTINUE THROUGH AT
LEAST THURSDAY.
* A PATTERN CHANGE WILL BRING COOLER TEMPERATURES, ELEVATED WINDS,
AND INCREASED PRECIPITATION CHANCES TO THE AREA LATER THIS

DISCUSSION
TODAY THROUGH MONDAY.
AN UPPER-LEVEL RIDGE OF HIGH PRESSURE WILL BEGIN BUILDING OVER THE
SOUTHWESTERN US TODAY. THIS RIDGE WILL ALLOW FOR DRY CONDITIONS
ACROSS SOUTHERN NEVADA, SOUTHEASTERN CALIFORNIA, AND NORTHWESTERN
ARIZONA, AS WELL AS WARMING TEMPERATURES FOR THE NEXT FEW DAYS.
BREEZY SOUTHWESTERLY TO WESTERLY WINDS WILL PICK UP ACROSS THE
MOJAVE DESERT ON WEDNESDAY AND THURSDAY IN RESPONSE TO A LOW
PRESSURE SYSTEM OFF THE COAST OF NORTHERN CALIFORNIA. TEMPERATURES
WILL PEAK ON WEDNESDAY, GRADUALLY DECREASING EACH DAY DURING THE
SECOND HALF OF THE WEEK AS 500 MB HEIGHTS FALL IN RESPONSE TO THIS
LOW APPROACHING THE AREA.
THIS AFOREMENTIONED LOW PRESSURE SYSTEM WILL CHURN OFF THE COAST OF
NORTHERN/CENTRAL CALIFORNIA BEFORE DROPPING SOUTH AND MOVING INLAND
LATER IN THE WEEK. AS THIS SYSTEM DIGS SOUTH ALONG THE COAST, WE
WILL SEE ELEVATED SOUTHWESTERLY WINDS PICK UP ACROSS THE REGION
ALONG WITH COOLING TEMPERATURES. PRECIPITATION CHANCES WILL INCREASE
ACROSS THE REGION AS WE HEAD INTO THE WEEKEND, WITH THE MOST
WIDESPREAD PRECIPITATION CHANCES EXPECTED ON SATURDAY AND SUNDAY.
MOUNTAINS AND AREAS OF HIGHER TERRAIN WILL HAVE THE BEST
PRECIPITATION CHANCES WITH DOWNSTREAM VALLEYS EXPERIENCING SOME
DEGREE OF RAIN-SHADOWING. INCREASED INSTABILITY ASSOCIATED WITH THE
TROUGH MEANS THAT WE CAN'T RULE OUT A RUMBLE OR TWO OF THUNDER WITH
STORMS AS THE BASE OF THE TROUGH SWINGS THROUGH.
