DISCUSSION
THROUGH SUNDAY.
IN THE WAKE OF YESTERDAY'S DISTURBANCE, LATEST WATER VAPOR IMAGERY
INDICATES ANOTHER SHORTWAVE EXTENDING FROM THE NORTHERN ROCKIES
SOUTHWESTWARD INTO NORTHERN CALIFORNIA THAT WILL SWING EASTWARD
TODAY. AS THIS WAVE MOVES OVER THE AREA, PRECIPITATION CHANCES
WILL BE MAINTAINED, MAINLY ACROSS NORTHERN INYO COUNTY AND THE
SOUTHERN GREAT BASIN WHERE ISOLATED TO SCATTERED SHOWERS ARE
EXPECTED THROUGH THIS AFTERNOON, GRADUALLY TAPERING OFF FROM WEST
TO EAST THROUGH THE EVENING. THIS AFTERNOON WHEN ASCENT IS
MAXIMIZED BENEATH THE PASSING WAVE, THERE IS A 10 TO 20 PERCENT
CHANCE OF EMBEDDED THUNDERSTORMS, WHICH COULD RESULT IN LOCALIZED
ENHANCEMENTS TO WINDS AND RAINFALL RATES. ADDITIONALLY, SNOW
LEVELS REMAIN AROUND 7000 FEET, SO FOR LOCATIONS ABOVE THIS
ELEVATION, A DUSTING TO AN INCH OR TWO OF SNOW CAN BE EXPECTED
BEFORE PRECIPITATION COMES TO AN END. OVERALL, QPF REMAINS FAIRLY
LIGHT, UNDER 0.25 INCH FOR MOST. TEMPERATURES TODAY WARM ABOUT 3
TO 5 DEGREES OVER YESTERDAY, THOUGH REMAIN AROUND 5 TO 10 DEGREES
BELOW NORMAL FOR LATE APRIL, TOPPING OUT GENERALLY IN THE LOWER
50S ACROSS THE HIGHER TERRAIN TO THE LOWER 70S ACROSS THE DESERT
VALLEYS.
TUESDAY ONWARD, A QUICK RETURN TO ABOVE NORMAL TEMPERATURES IS
EXPECTED, WITH ENSEMBLES AND CLUSTER ANALYSES REMAINING IN FAIRLY
GOOD AGREEMENT REGARDING THE EVOLUTION OF THE UPPER PATTERN. MID-
LEVEL RIDGING WILL BUILD OVER THE PACIFIC NORTHWEST AND GREAT
BASIN, WITH YET ANOTHER TROUGH EXPECTED TO DEVELOP OFF OF THE
SOUTHERN CALIFORNIA/BAJA COAST MIDWEEK. THIS SYSTEM IS PROGGED TO
TRANSLATE EASTWARD THROUGH THE END OF THE WORK WEEK, AND WILL BE
ACCOMPANIED BY AN UPTICK IN CLOUD COVER AND A RETURN OF LOW-ORDER
PRECIPITATION CHANCES, MAINLY SOUTH OF I-15 WEDNESDAY NIGHT AND
THURSDAY. GIVEN THE EXPECTED TRACK NEAR THE US/MEXICO BORDER,
MOISTURE ON THE NORTHERN PERIPHERY OF THIS SYSTEM WILL BE PALTRY,
WITH ONLY LIGHT SHOWERS EXPECTED AT THIS TIME. THAT SAID,
AFTERNOON HIGHS WILL BE TEMPERED SLIGHTLY ACROSS SOUTHERN ZONES ON
THURSDAY, BEFORE THE WARMING TREND RETURNS FRIDAY INTO THE
WEEKEND AS SHORTWAVE RIDGING BUILDS OVER THE REGION.
