PRETTY QUIET WEATHER PATTERN OVER THE NEXT SEVERAL DAYS WITH
NEAR TO SLIGHTLY ABOVE SEASONABLE TEMPERATURES. A FEW WEAK
DISTURBANCES WILL MOVE THROUGH THE REGION WITH THE FIRST COMING
THROUGH TONIGHT BUT THIS FIRST SYSTEM WILL STAY MOSTLY NORTH OF
THE AREA. DID KEEP IN A SLIGHT CHANCE OF SHOWERS FOR FAR NORTH
AND NORTHWEST PARTS OF THE CWA. GUSTY WINDS WILL ALSO ACCOMPANY
THIS DISTURBANCE OVERNIGHT TONIGHT AND THIS WILL INCREASE MIXING
WHICH COUPLED WITH INCREASED CLOUDS WILL KEEP OVERNIGHT LOWS A
BIT WARMER THAN OTHERWISE WOULD BE EXPECTED.
AN OVERALL ZONAL FLOW ALOFT WILL BE IN PLACE FROM LATE MONDAY
THROUGH THURSDAY WITH ANOTHER PERTURBATION MOVING THROUGH ON
WEDNESDAY WHICH WILL BE VERY SIMILAR TO TONIGHTS DISTURBANCE
WITH BOTH ORIGINATING OVER THE PACIFIC NORTHWEST AND BRUSHING
QUICKLY THROUGH THE AREA WITH MOST OF THE ENERGY PUSHED TO THE
NORTH OF THE AREA.
BY FRIDAY MORNING, ANOTHER BROADER DISTURBANCE WILL MOVE
THROUGH THE AREA AND THIS LOOKS TO EXPAND THE POTENTIAL FOR RAIN
SHOWERS TO THE ENTIRE AREA AND POSSIBLY A FEW RUMBLES OF
THUNDER ESPECIALLY FOR THE SOUTHERN HALF OF THE CWA. A DEEPER
TROUGH WITH A MUCH COLDER AIRMASS THEN LOOKS TO TAKE SHAPE TO
MOVE INTO THE AREA FOR THE SECOND HALF OF NEXT WEEKEND. WILL
NEED TO KEEP AN EYE ON THIS SYSTEM AS THE FIRST SNOWFLAKES OF
THE SEASON MAY BE POSSIBLE.
