...UNSETTLED WEATHER FOR THE NORTHWEST & NORTHERN CALIFORNIA, WITH
A THREAT FOR FLASH FLOODING WEDNESDAY AND THURSDAY FROM NORTHERN
CALIFORNIA TO THE OLYMPIC MOUNTAINS...
...A POTENT CLIPPER SYSTEM WILL MOVE THROUGH THE NORTHEAST
TOMORROW INTO THURSDAY, BRINGING THE THREAT FOR THUNDERSTORMS,
STRONG WINDS, AND HIGH ELEVATION SNOW...
...THE CENTRAL PART OF THE COUNTRY WILL SEE MOSTLY ABOVE AVERAGE
TEMPERATURES PREVAIL...
AN ATMOSPHERIC RIVER IS STARTING TO BRING RAIN ACROSS THE WEST
COAST THIS AFTERNOON, BUT SHOULD BEGIN TO PICK UP IN IMPACTS FOR
THE NORTHERN CALIFORNIA COASTLINE BY TOMORROW AS THE AREA OF LOW
PRESSURE NEARS. A FLOOD WATCH IS ACTIVE FOR PARTS OF THE EUREKA
WFO AS RAINFALL TOTALS IN THE 4-6 INCH RANGE COULD RESULT IN
EXCESSIVE WATER RUN-OFF FROM RIVERS/POOR DRAINAGE. WASHINGTON
STATE WILL SEE PLUMES OF MOISTURE/RAINFALL ON WEDNESDAY, THURSDAY,
AND FRIDAY AS THE AR CONTINUES. THERE IS A MARGINAL RISK FOR
EXCESSIVE RAINFALL ACROSS BOTH THE OLYMPIC MOUNTAINS AND NORTH
CALIFORNIA/SOUTHERN OREGON WEDNESDAY AND THURSDAY IN SUMMARY. THE
OTHER HAZARD WITH THE LOW PRESSURE SYSTEM/AR WILL BE THE STRONG
WINDS. HIGH WIND WARNINGS ARE IN EFFECT FROM COASTAL ZONES OF
NORTHERN CALIFORNIA AND SOUTHERN OREGON, AS WELL AS INTERIOR
MOUNTAIN RANGES. SOME POWER OUTAGES COULD OCCUR AS SUSTAINED WINDS
IN THE 25-25 MPH RANGE, GUSTING TO 60-70 ON THE HIGH END, ARE IN
THE FORECAST. ALSO, THE STORM PREDICTION CENTER DOES HAVE A
MARGINAL RISK ACROSS NO CAL/ OR WEDNESDAY FOR LOW TOPPED
CONVECTION THAT COULD CONTAIN ISOLATED HAIL, A SPIN-UP
TORNADO/WATER-SPOUT, AND SEVERE CRITERIA WIND GUSTS.
A SWIFT MOVING COLD FRONT WILL TRAVERSE THE NORTHEAST LATE
WEDNESDAY AFTERNOON AND EARLY THURSDAY. THERE WILL BE LIMITED
CONVECTION WITH THE FRONT, BUT ANY THUNDERSTORMS THAT DO DEVELOP
MAY BRING DAMAGING WINDS TO THE SURFACE. THEREFORE, SPC HAS ISSUED
A MARGINAL RISK FOR THE THREAT OF SEVERE CRITERIA WIND GUSTS.
SYNOPTIC WINDS MAY ALSO BE RATHER GUSTY, AND WEATHER OFFICES
ACROSS THE NORTHEAST HAVE HIGH WIND WATCHES AND ADVISORIES ACTIVE.
POWER OUTAGES WILL BE POSSIBLE. COLD AIR ADVECTION ON THE BACKSIDE
OF THE LOW PRESSURE WILL BRING SOME SNOWFALL LATE WEDNESDAY ACROSS
THE MOUNTAIN RANGES IN THE NORTHEAST SUCH AS THE GREEN, WHITE, AND
THE ADIRONDACKS. THERE WERE MODERATE PROBABILITIES OF AROUND 4
INCHES IN THE MOUNTAIN RANGES OF NEW ENGLAND AND LESSER AMOUNTS IN
THE ADIRONDACKS.
THE CENTRAL PART OF THE COUNTRY, PARTICULARLY THE SOUTHERN PLAINS,
WILL SEE ABOVE AVERAGE TEMPERATURES PREVAIL INTO FRIDAY. A WEAK
COLD FRONT WILL MOVE THOUGH THE MIDWEST AND PLAINS ON WEDNESDAY,
BUT RIDGING WILL QUICKLY BUILD BACK INTO THE REGION AHEAD OF A
FORMING WESTERN TROUGH. FOR HIGH TEMPERATURES, THE SOUTHERN PLAINS
WILL BE IN THE MIDDLE TO UPPER 80S FOR THE WORK WEEK, WHICH IS
AROUND 10-15 DEGREES WARMER THAN AVERAGE FOR THE TIME OF THE YEAR.
THE CENTRAL PLAINS MAY DIP INTO THE UPPER 50S TOMORROW BEHIND THE
COLD FRONT, BUT TEMPERATURES SHOULD REBOUND INTO THE 60S AND LOW
70S FOR THURSDAY INTO FRIDAY. THE SOUTHEAST WILL GENERALLY REMAIN
MILD IN THE MIDDLE TO UPPER 70S AS THE AIR MASS MODIFIES UNDER
POST-FRONTAL HIGH PRESSURE.
