DISCUSSION
THROUGH SATURDAY.
OUR BAND OF LIGHT TO MODERATE RAIN HAS SET UP ALONG THE I-15 AND I-
40 CORRIDORS. RAIN RATES HAVE GENERALLY BEEN AROUND 0.10" PER HOUR
OR LESS, WITH RAINFALL TOTALS ACROSS THE AREA RANGING FROM A TRACE
TO 0.33" AS OF 1230PM. HAVE SEEN ONLY A FEW LIGHTNING STRIKES SO
FAR, WITH BEST ODDS OF ADDITIONAL STRIKES ON THE NORTHERN EDGE OF
THE PRECIP BAND. BARRING ANY MORE ROBUST CONVECTIVE DEVELOPMENT,
ANTICIPATING RAINFALL REMAIN LIGHT TO MODERATE. ACTIVITY IS
EXPECTED TO WANE THIS EVENING ONCE THE SHORTWAVE MOVES THROUGH.
CLOUDS AND PRECIP WILL KEEP TEMPERATURES WELL BELOW NORMAL FOR
EARLY SEPTEMBER. HIGHS WILL RANGE FROM THE UPPER 70S TO LOW 90S
ACROSS THE AREA, WITH THE VALUES ON THE HIGHER END LIKELY BEING
"MIDNIGHT HIGHS".
AS THE PACIFIC TROUGH LIFTS NORTHWARD TOMORROW, WE LOSE THE FORCING
AND SOME OF THE MOISTURE THAT HELPED PRODUCE THE WIDESPREAD RAIN
TODAY. WE'LL STILL HAVE SOME HIGH CLOUDS AROUND, BUT DRIER
CONDITIONS RETURN ALONG WITH SEASONABLE TEMPERATURES. ENSEMBLE
GUIDANCE CONTINUES TO SHOW A RIDGE RETROGRADING BACK INTO THE DESERT
SOUTHWEST LATER THIS WEEK, PROMOTING A WARMING TREND THROUGH AT
LEAST THURSDAY. BY THAT TIME, THE FORECAST CALLS FOR HIGHS 3-7
DEGREES ABOVE NORMAL, WITH VALUES ECLIPSING THE CENTURY MARK OVER
MOST OF THE MOJAVE DESERT. HOWEVER, GUIDANCE ALSO KEEPS MODEST
MONSOONAL MOISTURE IN PLACE, ALLOWING LOW (LESS THAN 30%)
SHOWER/STORM CHANCES TO LINGER OVER THE HIGHER TERRAIN. A
WEAKENING OF THE RIDGE AND TRANSITION TO MORE ZONAL FLOW NEXT
WEEKEND SHOULD SCOUR MOISTURE OUT AND BRING TEMPERATURES DOWN
SLIGHTLY.
