PROGNOSTIC DISCUSSION FOR 6 TO 10 AND 8 TO 14 DAY OUTLOOKS
NWS CLIMATE PREDICTION CENTER COLLEGE PARK, MD
300 PM EST WED MARCH 05 2025
6-10 DAY OUTLOOK FOR MAR 11 - 15 2025
THE GEFS, EUROPEAN ENSEMBLE MEAN (ECENS), AND CANADIAN ENSEMBLE MEAN (CMCE)
SOLUTIONS ARE IN GOOD AGREEMENT ON THE MID-LEVEL MEAN CIRCULATION PATTERN
ACROSS THE FORECAST DOMAIN DURING THE 6-10 DAY PERIOD, AND SHOW GOOD CONTINUITY
WITH YESTERDAY’S SOLUTIONS. THE ECENS AND CMCE MODELS PREDICT A MODERATELY
STRONG ANOMALOUS RIDGE CENTERED OVER THE CENTRAL PACIFIC NEAR 40N/160W WITH
MAXIMUM POSITIVE HEIGHT ANOMALIES OF ABOUT 120 METERS. THE GEFS HAS A SOMEWHAT
WEAKER RIDGE IN THAT SAME GENERAL VICINITY, BUT ITS GREATEST POSITIVE HEIGHT
ANOMALIES ARE FORECAST OVER THE WESTERN PACIFIC. THE THREE ENSEMBLE MEANS ALSO
FORECAST ANOMALOUS TROUGHING THAT EXTENDS FROM ALASKA EASTWARD ACROSS NEARLY
ALL OF CANADA AND SOUTHWARD ACROSS THE WESTERN HALF TO TWO-THIRDS OF THE
CONTIGUOUS U.S. (CONUS). THE STRONGEST NEGATIVE HEIGHT ANOMALY CENTER (NEAR
-150 METERS) IS PREDICTED NEAR THE COAST OF THE PACIFIC NORTHWEST. ANOMALOUS
RIDGING IS PREDICTED OVER MUCH OF THE EAST. OVER THE CENTRAL PACIFIC, NEAR TO
SLIGHTLY ABOVE NORMAL 500-HPA HEIGHTS ARE FORECAST ACROSS THE VICINITY OF THE
HAWAIIAN ISLANDS.
THE 6-10 DAY TEMPERATURE OUTLOOK FAVORS ABOVE NORMAL TEMPERATURES FROM THE
CENTRAL AND SOUTHERN GREAT PLAINS EAST-NORTHEASTWARD TO THE ATLANTIC SEABOARD.
MAXIMUM PROBABILITIES FAVORING ABOVE NORMAL TEMPERATURES RANGE FROM 80-90
PERCENT OVER THE MID-ATLANTIC REGION. BELOW NORMAL TEMPERATURES ARE FAVORED
WEST OF THE CONTINENTAL DIVIDE, WITH A SLIGHT EXTENSION MAINLY INTO THE
NORTHERN HIGH PLAINS. MAXIMUM PROBABILITIES FAVORING BELOW NORMAL TEMPERATURES
RANGE FROM 80-90 PERCENT OVER CALIFORNIA AND PARTS OF ADJACENT STATES. THIS
LARGE-SCALE TEMPERATURE PATTERN IS CONSISTENT WITH NEARLY ALL TEMPERATURE TOOLS
AND THE PREDICTED MID-LEVEL CIRCULATION PATTERN. TEMPERATURES NORTH OF A LINE
FROM ABOUT WESTERN NEBRASKA EASTWARD TO THE UPPER GREAT LAKES HAVE BEEN REDUCED
A BIT FROM THE AUTOMATED AND CONSOLIDATED TEMPERATURE TOOLS, TO ACCOUNT FOR A
STORM SYSTEM THAT MAY DEPOSIT A SWATH OF SIGNIFICANT SNOW ACCUMULATION TO THIS
REGION. THERE IS SIGNIFICANT UNCERTAINTY REGARDING THE ALASKA TEMPERATURE
OUTLOOK, BUT THE BEST CHANCES FOR BELOW NORMAL TEMPERATURES ARE OVER THE
NORTHERN AND FAR EASTERN PORTIONS OF THE MAINLAND, AND THE PANHANDLE. THIS IS
ATTRIBUTED TO THE FORECAST OF MID-LEVEL TROUGHING, BELOW NORMAL HEIGHTS, AND
EASTERLY FLOW AT THE SURFACE AND MID-LEVELS. MOST OF THE REMAINDER OF THE STATE
IS FAVORED TO EXPERIENCE NEAR NORMAL TEMPERATURES WITH THE EXCEPTION OF THE
EASTERN ALEUTIANS AND ALASKA PENINSULA, WHERE THERE IS A SLIGHT TILT TOWARDS
ABOVE NORMAL TEMPERATURES IN WEST-SOUTHWEST FLOW AROUND THE CREST OF THE
CENTRAL PACIFIC RIDGE. AT LOWER LATITUDES, RELATIVELY WARM SEA-SURFACE
TEMPERATURES (SSTS) AND NEAR TO SLIGHTLY ABOVE NORMAL 500-HPA HEIGHTS TILT THE
ODDS TOWARDS ABOVE NORMAL TEMPERATURES FOR THE HAWAIIAN ISLANDS, AND IS ALSO
SUPPORTED BY THE AUTOMATED AND ERF CON TEMPERATURE TOOLS.
THE 6-10 DAY PRECIPITATION OUTLOOK FAVORS ABOVE NORMAL PRECIPITATION OVER A
LARGE PORTION OF THE CONUS, WITH THE GREATEST PROBABILITIES RANGING FROM 70 TO
80 PERCENT OVER CALIFORNIA AND PARTS OF NEIGHBORING STATES. MOST OF THE
PRECIPITATION TOOLS SUPPORT THIS LARGE-SCALE ANOMALOUS WETNESS. THE FORECAST IS
ALSO CONSISTENT WITH PREDICTED ONSHORE FLOW AND MID-LEVEL TROUGHING (WEST) AND
MOIST RETURN FLOW FROM THE GULF (EAST). DURING THE 6-10 DAY PERIOD, THE
ENHANCED STORMINESS IS PREDICTED TO BE FOCUSED ACROSS CALIFORNIA AND PARTS OF
THE FOUR CORNERS STATES, WITH A GRADUAL NORTHWARD SHIFT OF THE PRECIPITATION
FORECASTED DURING WEEK-2. BELOW NORMAL PRECIPITATION CHANCES ARE ENHANCED FROM
MUCH OF THE SOUTHERN PLAINS INTO WESTERN LOUISIANA. FOR ALASKA, THERE ARE
VARIATIONS AMONG THE PRECIPITATION TOOLS, BUT A REASONABLE COMPROMISE FAVORS
INCREASED CHANCES OF ABOVE NORMAL PRECIPITATION OVER THE EXTREME SOUTHWESTERN
MAINLAND, THE ALASKA PENINSULA, AND THE ALEUTIANS, ASSOCIATED WITH BROAD
SURFACE LOW PRESSURE. BELOW NORMAL PRECIPITATION IS SLIGHTLY FAVORED OVER THE
NORTHERN HALF OF THE MAINLAND, CONSIDERED TO BE SUFFICIENTLY REMOVED FROM THE
MEAN STORM TRACK AND JET STREAM. THE GREATEST DISCREPANCIES IN THE
PRECIPITATION TOOLS CONTINUE TO BE IN SOUTHEAST ALASKA, WHICH IS WHY NEAR
NORMAL PRECIPITATION IS FAVORED THERE. FOR HAWAII, THE AUTOMATED AND ERF CON
PRECIPITATION TOOLS FAVOR INCREASED ODDS OF ABOVE NORMAL PRECIPITATION DURING
THE 6-10 DAY FORECAST PERIOD.
THE OFFICIAL 6-10 DAY 500-HPA HEIGHT BLEND CONSISTS OF 30% OF TODAY'S 0Z GFS
ENSEMBLE MEAN CENTERED ON DAY 8, 40% OF TODAY'S 0Z EUROPEAN ENSEMBLE MEAN
CENTERED ON DAY 8, AND 30% OF TODAY'S 0Z CANADIAN ENSEMBLE MEAN CENTERED ON DAY
8
FORECAST CONFIDENCE FOR THE 6-10 DAY PERIOD: ABOVE AVERAGE, 4 ON A SCALE OF
1-5, DUE TO GENERALLY GOOD AGREEMENT AMONG THE MODELS AND TOOLS, OFFSET BY SOME
DIFFERENCES IN THE TOOLS REGARDING THE ALASKA SURFACE FIELDS.
8-14 DAY OUTLOOK FOR MAR 13 - 19 2025
DURING WEEK-2, THE MULTI-MODEL ENSEMBLES ARE IN FAIRLY GOOD AGREEMENT ON THE
MAIN LARGE-SCALE CIRCULATION FEATURES ACROSS NORTH AMERICA, BUT THERE ARE
SIGNIFICANT DIFFERENCES UPSTREAM IN THE PREDICTED PHASE AND AMPLITUDE OF THE
ANOMALOUS RIDGE THAT WAS CENTERED OVER THE CENTRAL PACIFIC (40N/160W) DURING
THE EARLIER 6-10 DAY PERIOD. THOUGH THE MODELS HAVEN’T CONVERGED ON A UNIQUE
SOLUTION, THEY SHIFT THE RIDGE WESTWARD AND SOMEWHAT TO THE NORTH
(40-46N/175W-170E) DURING WEEK-2. THE PREDICTED AMPLITUDES OF THIS ANOMALOUS
RIDGE ARE IN EXCESS OF +150 METERS (GEFS) AND NEAR +100 METERS (ECENS AND
CMCE). THE ANOMALOUS TROUGHING DEPICTED BY THE MODELS IN THE EARLIER 6-10 DAY
PERIOD IS FORECAST TO CONTINUE OVER ALASKA, AT LEAST THE WESTERN HALF OF
CANADA, AND MOST OF THE CONUS. THE DYNAMICAL MODELS PREDICT A MAXIMUM NEGATIVE
HEIGHT ANOMALY OF -90 TO -120 METERS, LOCATED IN THE GENERAL VICINITY OF THE
PACIFIC NORTHWEST COAST. IN ADDITION, 500-HPA HEIGHTS ARE FORECAST TO BE CLOSE
TO NORMAL ALONG THE EASTERN SEABOARD AND MODESTLY ABOVE NORMAL OVER THE GULF
COAST/FLORIDA. OVER THE VICINITY OF HAWAII, 500-HPA HEIGHTS ARE PREDICTED TO BE
NEAR OR SLIGHTLY ABOVE NORMAL DURING WEEK-2.
THE 8-14 DAY TEMPERATURE PATTERN FAVORS ABOVE NORMAL TEMPERATURES FROM THE
SOUTHERN PLAINS EASTWARD AND NORTHEASTWARD TO THE ATLANTIC COAST. MAXIMUM
PROBABILITIES FAVORING ABOVE NORMAL TEMPERATURES RANGE FROM 50-60 PERCENT OVER
THE MID-ATLANTIC REGION. MUCH OF THIS RELATIVELY WARM AREA IS FORECAST TO BE
ASSOCIATED WITH SOUTHWESTERLY RETURN FLOW CIRCULATING AROUND AN AREA OF SURFACE
HIGH PRESSURE OVER THE WESTERN ATLANTIC. THIS IS WELL SUPPORTED BY THE
AUTOMATED AND REFORECAST TEMPERATURE TOOLS, BUT THE BIAS-CORRECTED AND RAW 6Z
GEFS TEMPERATURES (WHICH STRONGLY INFLUENCE THE NAEFS) DIFFER BY FAVORING
WIDESPREAD BELOW NORMAL TEMPERATURES. THIS SEEMS SIGNIFICANTLY LESS LIKELY TO
BE VERIFIED THAN THE OTHER MODEL SOLUTIONS AND HAS THEREFORE BEEN DISCOUNTED.
FROM THE UPPER GREAT LAKES, UPPER MISSISSIPPI VALLEY, NORTHERN HALF OF THE
LOWER PLAINS, AND MUCH OF THE HIGH PLAINS WESTWARD ACROSS THE ROCKIES TO THE
PACIFIC COAST, UNDER A LARGE MID-LEVEL TROUGH AND WELL BELOW-NORMAL HEIGHTS,
BELOW NORMAL TEMPERATURE CHANCES ARE SIGNIFICANTLY INCREASED RELATIVE TO
CLIMATOLOGICAL ODDS. MAXIMUM PROBABILITIES FAVORING BELOW NORMAL TEMPERATURES
RANGE FROM 70-80 PERCENT FOR MANY AREAS WEST OF THE CONTINENTAL DIVIDE. THE
BELOW NORMAL TEMPERATURES FAVORED OVER THE NORTH-CENTRAL CONUS ARE DUE TO THE
FORECAST OF A POWERFUL LOW PRESSURE SYSTEM THAT IS EXPECTED TO DEPOSIT A
SIGNIFICANT AMOUNT OF SNOW ACROSS MUCH OF THIS REGION IN THE DAYS 8-11
TIMEFRAME, IN COMBINATION WITH COLD AIR ADVECTION. THE ALASKA TEMPERATURE
OUTLOOK FOR WEEK-2 FEATURES BROADER COVERAGE OF FAVORED BELOW NORMAL
TEMPERATURES RELATIVE TO THE EARLIER 6-10 DAY PERIOD, WITH MOST OF THE STATE
FAVORED TO BE ANOMALOUSLY COLD. THIS IS SUPPORTED BY THE MANUAL HEIGHT BLEND
AND MOST OF THE SURFACE TEMPERATURE TOOLS, THOUGH SOME TOOLS FAVOR ANOMALOUS
WARMTH ACROSS THE ALEUTIANS AND THE ALASKA PENINSULA. WELL TO THE SOUTH OVER
THE CENTRAL PACIFIC, ABOVE NORMAL TEMPERATURE CHANCES ARE FAVORED FOR THE
HAWAIIAN ISLANDS DUE TO SURROUNDING ANOMALOUSLY WARM SSTS AND NEAR TO ABOVE
NORMAL MID-LEVEL HEIGHTS.
THE 8-14 DAY PRECIPITATION PATTERN FAVORS ABOVE NORMAL PRECIPITATION FOR MOST
OF THE LOWER 48 STATES. AS WAS THE CASE DURING THE EARLIER 6-10 DAY PERIOD,
THE FAVORED ABOVE NORMAL PRECIPITATION OVER THE WEST IS ATTRIBUTED TO A
COMBINATION OF ONSHORE FLOW AND A FAIRLY DEEP WESTERN CONUS TROUGH ACCOMPANIED
BY WELL BELOW NORMAL HEIGHTS. THE ANOMALOUS WETNESS OVER THE EAST IS DUE TO
INCREASED INFLOW OF GULF MOISTURE AND THE PASSAGE OF WHAT COULD BE A
SIGNIFICANT SPRING STORM SYSTEM DURING THE FIRST HALF OF THE FORECAST PERIOD,
ACCOMPANIED BY A VARIETY OF WEATHER-RELATED HAZARDS. THIS STORM SYSTEM IS
EXPECTED TO FORM IN THE LEE OF THE COLORADO ROCKIES AND TRAVEL ACROSS THE
CENTRAL PLAINS TOWARDS THE GREAT LAKES REGION. TODAY’S GEFS, ECENS, AND CMCE
HAVE COME INTO VERY GOOD AGREEMENT ON THE DEVELOPMENT AND EVOLUTION OF THIS
FEATURE. IN THE WARM SECTOR, HEAVY RAINFALL AND STRONG THUNDERSTORMS ARE
POSSIBLE OVER A LARGE PORTION OF THE EAST. CLIMATOLOGICALLY, THE LOWER
MISSISSIPPI VALLEY IS MOST FAVORED FOR THUNDERSTORM ACTIVITY). NORTH AND WEST
OF THE STORM TRACK, HEAVY SNOW AND STRONG WINDS ARE A DECENT POSSIBILITY.
RESIDENTS FROM ABOUT THE CENTRAL PLAINS NORTHEASTWARD TOWARDS THE GREAT LAKES
REGION ARE ADVISED TO MONITOR FUTURE DEVELOPMENTS WITH THIS POTENTIALLY
POWERFUL SPRING STORM SYSTEM. IN THE WEST, MAXIMUM PROBABILITIES FAVORING ABOVE
NORMAL PRECIPITATION RANGE FROM 50-60 PERCENT OVER THE WEST COAST STATES AND
ARIZONA, REFLECTING A GRADUAL REDUCTION OF PROBABILITIES FROM THE LAST SEVERAL
DAYS. BELOW NORMAL PRECIPITATION IS FAVORED FROM THE SOUTHERN PLAINS INTO
WESTERN LOUISIANA, WELL REMOVED FROM THE PREDICTED MEAN STORM TRACK AND JET
STREAM. THIS PRECIPITATION PATTERN FORECASTED OVER THE LOWER 48 STATES IS
STRONGLY SUPPORTED BY THE AUTO AND CONSOLIDATED PRECIPITATION TOOLS. OVER
ALASKA, THERE IS SIGNIFICANTLY MORE UNCERTAINTY IN THE PRECIPITATION OUTLOOK
THAN OVER THE CONUS. A SUBJECTIVE CONSENSUS OF ALL THE AVAILABLE PRECIPITATION
TOOLS FAVORS A SLIGHT TILT TOWARDS RELATIVE DRYNESS OVER APPROXIMATELY THE
NORTHWESTERN HALF OF THE MAINLAND, WITH ABOVE NORMAL PRECIPITATION FAVORED OVER
THE SOUTHERN MAINLAND, THE ALASKA PENINSULA, AND THE ALEUTIANS. THE REMAINDER
OF ALASKA, WHICH COMPRISES A SUBSTANTIAL PORTION OF THE STATE, IS FAVORED TO
HAVE NEAR NORMAL PRECIPITATION. THE HAWAIIAN ERF CON AND AUTOMATED
PRECIPITATION TOOLS PREDICT A WEAK TILT IN THE ODDS TOWARDS ABOVE NORMAL
PRECIPITATION FOR MOST OF THE ISLANDS DURING WEEK-2.
THE OFFICIAL 8-14 DAY 500-HPA HEIGHT BLEND CONSISTS OF: 30% OF TODAY'S 0Z GFS
ENSEMBLE MEAN CENTERED ON DAY 11, 40% OF TODAY'S 0Z EUROPEAN ENSEMBLE MEAN
CENTERED ON DAY 11, AND 30% OF TODAY'S 0Z CANADIAN ENSEMBLE MEAN CENTERED ON
DAY 11
FORECAST CONFIDENCE FOR THE 8-14 DAY PERIOD: ABOVE AVERAGE, 4 ON A SCALE OF
1-5, DUE TO GENERALLY GOOD AGREEMENT AMONG THE MODELS AND TOOLS, OFFSET BY SOME
DIFFERENCES IN THE TOOLS REGARDING THE ALASKA SURFACE FIELDS.

NOTES:
AUTOMATED FORECASTS ARE ISSUED ON SATURDAY AND SUNDAY. OCCASIONALLY MANUAL
INTERVENTION IS NECESSARY TO ADDRESS QUALITY CONTROL AND CONSISTENCY ISSUES. IN
THESE CASES, FORECASTS ARE MANUALLY DRAWN BUT A FULL DISCUSSION IS NOT ISSUED.
THE NOTATION FOR THE CATEGORICAL FORECAST INDICATED ON THE MAPS IS THE SAME AS
THAT IN THE TABLES: A-ABOVE N-NEAR NORMAL B-BELOW
THE TEMPERATURE MAP SHOWS REGIONS WITH > 33% CHANCE OF BEING WARMER (ORANGE,
"A"), COLDER (BLUE, "B"), OR CLOSE TO (UNSHADED, "N"). HISTORICAL AVERAGE
VALUES FOR THE CALENDAR PERIOD OF THE FORECAST (DASHES, "F"). LABELS ON THE
SHADED LINES GIVE THE PROBABILITY (> 33%) OF THE MORE LIKELY CATEGORY (B OR A).
PROBABILITY OF N IS ALWAYS < 40%.
THE PRECIPITATION MAP SHOWS REGIONS WITH > 33% CHANCE OF BEING WETTER (GREEN,
"A"), DRIER (TAN, "B"), OR CLOSE TO (UNSHADED, "N"). HISTORICAL MEDIAN VALUES
FOR THE CALENDAR PERIOD OF THE FORECAST (DASHES, "INCHES"). LABELS ON THE
SHADED LINES GIVE THE PROBABILITY (> 33%) OF THE MORE LIKELY CATEGORY (B OR A).
PROBABILITY OF N IS ALWAYS < 40%.
IN THE SOUTHWEST AND OTHER CLIMATOLOGICALLY DRY REGIONS - THERE WILL BE A
GREATER THAN 33.3% CHANCE OF NO PRECIPITATION AND OCCASIONALLY EVEN A NORMAL
(I.E. MEDIAN) VALUE OF ZERO - ESPECIALLY DURING THE DRY SEASONS. IN SUCH CASES
A FORECAST OF NEAR NORMAL IS EFFECTIVELY A FORECAST OF LITTLE OR NO
PRECIPITATION.
THE CLIMATE PREDICTION CENTER USES 1991-2020 BASE PERIOD MEANS AS REFERENCE IN
THE CLIMATE OUTLOOKS.
THE NEXT SET OF LONG-LEAD MONTHLY AND SEASONAL OUTLOOKS WILL BE RELEASED ON
MARCH 20.
