CONDITIONS CONTINUE THIS WEEKEND INTO NEXT WEEK
DISCUSSION
SATELLITE HAS CLEAR SKIES OVER INTERIOR CALIFORNIA THIS
AFTERNOON, WITH TEMPERATURES IN THE 70S AND 80S. WE ARE EXPECTING
HIGHS TO REACH INTO THE UPPER 80S TO LOWER 90S TODAY, WITH COOLER
CONDITIONS WITHIN THE HIGHER TERRAIN. WINDS REMAIN LIGHT, WITH
OCCASIONAL BREEZY WINDS WITHIN THE DELTA, NORTHERN SAN JOAQUIN
VALLEY, AND SOUTHERN SACRAMENTO VALLEY THIS EVENING. THIS WILL
HELP COOL TEMPERATURES OFF QUICKLY THIS EVENING AND OVERNIGHT.
CLOUDS WILL MOVE BACK IN THROUGH THE DELTA AND SPREAD THROUGH THE
SOUTHERN SACRAMENTO VALLEY AND NORTHERN SAN JOAQUIN VALLEY
OVERNIGHT INTO TOMORROW MORNING. THIS BRINGS OVERCAST TO BROKEN
CLOUDS AND LOWER CEILINGS. ONCE THE SUN RISES TOMORROW CLOUDS WILL
START TO MIX OUT AND TEMPERATURES CLIMB.
TEMPERATURES WILL BE AROUND SEASONAL AVERAGES SUNDAY INTO THE
WEEK AHEAD, WITH A FEW DAYS SLIGHTLY ABOVE AVERAGE. WE WILL
CONTINUE THIS DRY AND MILD WEATHER PATTERN THROUGH THE WEEK, WITH
AFTERNOON HUMIDITY CONDITIONS IN THE 30-50 PERCENT RANGE ACROSS
THE VALLEY, OUTSIDE A POCKET OF DRIER CONDITIONS OVER THE NORTHERN
SACRAMENTO VALLEY. AS WE APPROACH NEXT WEEKEND, MODELS START TO
DIVERGE ON A SOLUTION AS THEY TRY TO HANDLE THE BREAKDOWN OF THE
RIDGE OVER THE SW UNITED STATES. BREAKDOWN OF THE RIDGE WOULD
ALLOW FOR UPPER LEVEL SYSTEMS TO TRANSLATE ACROSS THE AREA, WHILE
A STAGNANT RIDGE WOULD CONTINUE OUR DRY CONDITIONS.
AVIATION
VFR CONDITIONS PREVAIL THROUGH THE EVENING HOURS, WITH POTENTIAL
MVFR CONDITIONS 6Z THROUGH 16Z FOR THE SACRAMENTO SITES. THIS IS
DUE IN PART TO THE LOW STRATUS DEVELOPING WITHIN THE DELTA PUSHING
INTO THE SACRAMENTO METRO LATER THIS EVENING AND THROUGH THE MID
MORNING HOURS. THIS WOULD BRING 1000-3000 FOOT CEILINGS AT TIMES,
WITH A BKN TO OVC CLOUD DECK. OTHER SITES WOULD SEE SCT TO FEW
CLOUDS AROUND 5000 FEET. OTHERWISE, DURING THIS AFTERNOON AND
EVENING A FEW GUSTS TO 20KTS WILL BE POSSIBLE FOR RDD AND RBL.
STO WATCHES/WARNINGS/ADVISORIES
