CURRENTLY THIS AFTERNOON, TROUGHING IS CENTERED TO OUR EAST WITH
SURFACE HIGH PRESSURE REMAINING IN PLACE. THIS WILL CONTINUE THE DRY
PATTERN WE'VE HAD IN RECENT DAYS WITH MILD DAYTIME TEMPERATURES AND
ANOTHER COOL NIGHT TONIGHT. ON SATURDAY, RIDGING WILL LEAD TO HEIGHT
RISES WITH SURFACE HIGH PRESSURE SHIFTING TO THE SOUTH. THIS
INCREASE IN HEIGHTS AND SOUTHERLY FLOW WILL LEAD TO WARMER
TEMPERATURES THAN TODAY. A SYSTEM WILL ALSO MOVE NORTHEAST OF OUR
AREA WITH A FRONTAL BOUNDARY APPROACHING FROM THE NORTHWEST SATURDAY
NIGHT. THIS WILL LEAD TO A RETURN OF RAIN CHANCES WITH INSTABILITY
AND DYNAMICS REMAINING LARGELY TO THE NORTHEAST, KEEPING CONVECTION
OUT OF OUR AREA. HOWEVER, WSW 850MB FLOW WILL REACH 40 TO 50 KTS.
WHILE THE SETUP DOES NOT REALLY FAVOR MOUNTAIN WAVES, SYNOPTIC WINDS
THIS STRONG WILL LIKELY LEAD TO ADVISORY-LEVEL WINDS IN THE
MOUNTAINS WITH BREEZY CONDITIONS AREA-WIDE. BEHIND THE FRONT, COOLER
AND DRIER CONDITIONS WILL RETURN BY SUNDAY.
HIGH PRESSURE WILL REMAIN ON MONDAY, BUT A WEAK INITIAL SYSTEM TO
OUR WEST COMES INTO VIEW. THIS WILL LEAD TO ANOTHER RETURN OF LOW-
END RAIN CHANCES ON TUESDAY. BY THE MIDDLE OF THE WEEK, HOWEVER,
DEEPENING TROUGHING WILL BECOME CUT OFF FROM THE MAIN FLOW WITH A
MORE ROBUST SYSTEM APPROACHING FROM THE WEST WITH SOUTHERLY FLOW
PULLING THE FRONTAL BOUNDARY BACK NORTHWARD. A LOT STILL REMAINS
UNCERTAIN ABOUT THE OVERALL EVOLUTION AND TRACK OF THIS SYSTEM, BUT
A RETURN OF HIGHER RAIN CHANCES IS EXPECTED DURING THE SECOND HALF
OF THE WEEK REGARDLESS.
