DISCUSSION
A STRENGTHENING WAVE OF LOW PRESSURE AND ARCTIC COLD FRONT WILL CROSS
THE EVENT LOCATION LATE SATURDAY INTO SUNDAY. SNOW LOOKS TO BE THE
THE PRIMARY PRECIPITATION TYPE WITH THIS EVENT ALTHOUGH THE OVERALL
TRACK AND INTENSITY OF THE SYSTEM HAVE YET TO BE RESOLVED. CURRENT
PROBABILITIES FOR AN INCH OF SNOW OVER THE EVENT LOCATION REMAIN
BETWEEN 50 TO 60 PERCENT. THESE PROBABILITIES DROP DOWN TO 35 TO 45 PERCENT
FOR TWO INCHES OF SNOW. A WORST CASE SCENARIO WOULD BE AMOUNTS UP
TO FOUR INCHES(ALTHOUGH PROBABILITIES ARE LESS THAN 15 PERCENT)
PENDING A SLIGHT WESTWARD SHIFT OF THE GREATEST AXIS OF LIFT
AND A SLIGHT SOUTHWARD TRACK OF THE LOW. THE SNOW WILL LIKELY OCCUR
WITHIN A 6 TO 12 HOUR WINDOW STARTING LATE SATURDAY EVENING AND
CONTINUING THROUGH EARLY SUNDAY MORNING.
ARCTIC HIGH PRESSURE WILL QUICKLY BUILD IN THEREAFTER AS
LOW PRESSURE DEPARTS NORTHEAST AND THE FRONT PUSHES OFFSHORE. THIS
WILL ALLOW FOR BLUSTERY CONDITIONS AS THE PRESSURE GRADIENT TIGHTENS.
WIND GUSTS OF 25 TO 35 MPH CAN BE EXPECTED SUNDAY INTO SUNDAY NIGHT.
LOCALLY HIGHER GUSTS ARE POSSIBLE ALONG THE RIDGELINES AND WESTERN FACING
EXPOSURES. WITH THE WIND WILL COME BITTER WIND CHILLS AS TEMPERATURES DROP FROM
THE MID TO UPPER 20S SUNDAY INTO THE TEENS SUNDAY NIGHT. EXPECT WIND
CHILLS IN THE UPPER SINGLE DIGITS AND MID TEENS DURING THE DAYLIGHT HOURS SUNDAY
FALLING TO NEAR 0 OR BELOW ZERO SUNDAY NIGHT.
COLD TEMPERATURES WILL CONTINUE INTO MONDAY WITH HIGH PRESSURE OVERHEAD BEFORE
WARMING INTO THE MIDDLE OF NEXT WEEK.
