SFC HIGH PRES CONTD TO SLOLY SHIFT EWD TODAY WITH THE AXIS SITUATED
OVR ERN AR AT MID AFTN. THE AIRMASS MODIFIED QUITE NICELY OVR WRN
AND CNTRL AR WHERE MID AFTN TEMPS WERE IN THE 60S AND LOWER 70S. THE
COLDER AIR ASSOCD WITH THE HIGH WAS LINGERING OVR ERN AR WHERE
READINGS WERE STILL IN THE 50S.

THE AFOREMENTIONED HIGH PRES RDG WL CONT TO SHIFT EWD TNGT AND WED.
THIS WL ALLOW FOR S/SELY WINDS TO RETURN TO THE ENTIRE FA HEADING

REINFORCING SHOT OF COOLER AND DRIER AIR FOR FRI. THE NEXT CHC FOR
ANY ORGANIZED PRECIP WL RETURN TO WRN AR LATE FRI NGT...WITH BETTER
CHCS HEADING INTO THE UPCOMING WEEKEND.

LONG TERM...SATURDAY THROUGH TUESDAY

LONG TERM BEGINS WITH HIGH PRESSURE DEPARTING TO THE EAST AND
PRECIPITATION ON OUR DOORSTEP TO THE WEST. SURFACE LOW PRESSURE WILL
TRACK TOWARDS THE STATE THROUGH THE WEEKEND AND BRING PRECIPITATION
THROUGH SUNDAY EVENING. MODELS DID TEND TO COME BACK A BIT WARMER
THIS MORNING AND AS A RESULT DID BUMP TEMPS UP A DEGREE OR TWO.
HOWEVER THIS DOES STILL KEEP WINTRY PRECIPITATION IN THE FORECAST
SATURDAY MORNING AND AGAIN SUNDAY AFTERNOON. CURRENT FORECAST HAS
TEMPS STAYING STEADY OR EVEN WARMING DURING THE OVERNIGHT HOURS
SATURDAY NIGHT WITH THE COLD FRONT MOVING THROUGH THE STATE EARLY
SUNDAY MORNING. THIS WOULD RESULT IN SFC TEMPS FALLING THROUGH THE
DAY ON SUNDAY AND THE RETURN OF WINTRY PRECIPITATION CHANCES.
AGAIN...THIS SYSTEM IS STILL FAIRLY FAR OUT...AND WITH THE TIMING OF
THE FRONT LIKELY TO CHANGE...IT WOULD GREATLY EFFECT THE PRECIP TYPE
FORECAST. PLEASE CONTINUE TO MONITOR FORECAST UPDATES IN THE COMING
DAYS.

BEHIND THIS SYSTEM...HIGH PRESSURE BUILDS INTO THE REGION FOR THE
NEW WORK WEEK. THIS RESULTS IN DRY WEATHER AND SLIGHTLY BELOW NORMAL
TEMPERATURES TO CLOSE OUT THE LONG TERM.
