PROGNOSTIC DISCUSSION FOR 6 TO 10 AND 8 TO 14 DAY OUTLOOKS
NWS CLIMATE PREDICTION CENTER COLLEGE PARK, MD
300 PM EDT WED MARCH 27 2024
6-10 DAY OUTLOOK FOR APR 02 - 06 2024
DYNAMICAL MODEL FORECASTS ARE IN GOOD AGREEMENT ON THE OVERALL LARGE-SCALE MEAN
500-HPA HEIGHT PATTERN DURING THE 6-10 DAY PERIOD, BUT ONLY IN FAIR AGREEMENT
WITH MODEL SOLUTIONS FROM YESTERDAY. AT THE START OF THE PERIOD, A STRONG RIDGE
IS CENTERED NEAR GREENLAND, WITH ALL ENSEMBLE MEANS SHOWING A CLOSED MID-LEVEL
HIGH WITH 500-HPA HEIGHTS OF AROUND 555 DM. TO THE SOUTH, A STRONG TROUGH IS
CENTERED OVER THE NORTH ATLANTIC (FARTHER EAST THAN YESTERDAY) WITH AN
ELONGATED STRETCH OF SUBNORMAL 500-HPA HEIGHTS EXTENDING WESTWARD INTO THE
NORTHEASTERN CONTIGUOUS UNITED STATES (CONUS). THESE TWO FEATURES ARE
REPRESENTATIVE OF A STRONG NEGATIVE PHASE OF THE NORTH ATLANTIC OSCILLATION
(NAO). THE MAGNITUDE OF THE NEGATIVE NAO WEAKENS WITH TIME, BUT IT SHOULD
REMAIN NEGATIVE THROUGH THE NEXT TWO WEEKS. IN APRIL, A NEGATIVE NAO GENERALLY
CORRELATES WITH BELOW-NORMAL TEMPERATURES ACROSS MUCH OF THE CONUS, ESPECIALLY
WEST OF THE MISSISSIPPI RIVER, AND WITH ABOVE-NORMAL PRECIPITATION IN PARTS OF
THE FAR WEST, THE CENTRAL GREAT PLAINS, AND MUCH OF THE SOUTHEAST.
HISTORICALLY, HOWEVER, THERE HAS BEEN CONSIDERABLE VARIABILITY, SO THESE
CORRELATIONS AREN’T HARD-AND-FAST RULES. YESTERDAY, IT APPEARED THAT THESE
HISTORIC CORRELATIONS WOULD LARGELY BE FAVORED FOR THE CURRENT 6- TO 10-DAY AND
WEEK-2 PERIODS, BUT DUE TO CHANGES IN TODAY’S GUIDANCE, THE FORECASTS DO NOT
AGREE AS WELL WITH THE HISTORIC CORRELATIONS, PARTICULARLY IN THE WESTERN HALF
OF THE CONUS.
MEANWHILE, A MID-LEVEL RIDGE IS EXPECTED TO BE CENTERED IN THE NORTH PACIFIC AT
THE BEGINNING OF THE PERIOD, WITH ABOVE-NORMAL HEIGHTS EXTENDING NORTHWARD INTO
CENTRAL AND SOUTHERN ALASKA, AND EASTWARD INTO A SECOND POSITIVELY-TILTED RIDGE
AXIS FROM WESTERN CANADA TO THE NORTH PACIFIC NEAR THE NORTHWESTERN CONUS
COAST. TO THE EAST, A MID-LEVEL TROUGH IN THE CENTRAL CONUS IS EXPECTED TO BE
IMPINGING ON THE EASTERN CONUS IN THE WAKE OF A MID-LEVEL RIDGE PUSHING OUT TO
SEA. AS THE MID-LEVEL TROUGH SHIFTS EASTWARD, THE GREATEST NEGATIVE 500-HPA
ANOMALIES WILL COVER THE NORTHEAST, WITH A WEAK POSITIVELY-TILTED TROUGH AXIS
EXTENDING SOUTHWESTWARD TO A SECONDARY ANOMALY CENTER IN THE SOUTH-CENTRAL
GREAT PLAINS. THIS IS THE SECOND CONSECUTIVE DAY THAT DYNAMICAL MODELS HAVE
WEAKENED THIS FEATURE. THE PATTERN FAVORS A RELATIVELY WEAK SURFACE LOW
PRESSURE SYSTEM MOVING THROUGH THE NORTHEAST WITH A TRAILING COLD FRONT
EXTENDING SOUTHWARD TO OFF THE MID-ATLANTIC COAST AND INTO THE SOUTHEAST. THIS
IS FORECAST TO TRIGGER MODERATE PRECIPITATION IN THE NORTHEASTERN CONUS (DUE TO
THE SURFACE LOW PRESSURE CENTER) AND THE SOUTHEAST (ALONG ITS TRAILING COLD
FRONT).
THE PATTERN IS FAIRLY PROGRESSIVE OVER THE 5-DAY PERIOD, BUT HAS TRENDED A
LITTLE LESS SO COMPARED TO YESTERDAY. OVER AND NEAR NORTH AMERICA, THE MEAN
HEIGHT FIELD DOESN’T FIT TELECONNECTIONS WELL, IMPLYING THAT THE PATTERN IS IN
TRANSITION, WHICH WOULD SUPPORT A CHANGING, PROGRESSIVE REGIME. BY THE END OF
THE PERIOD, THE MID-LEVEL TROUGH WILL HAVE MOVED THROUGH THE EAST AND INTO THE
ATLANTIC, LEAVING A VERY WEAK RIDGE WITH NEAR NORMAL 500-HPA HEIGHTS OVER THE
EASTERN CONUS. FARTHER WEST, A SIGNIFICANT MID-LEVEL TROUGH WILL HAVE DROPPED
INTO THE WESTERN CONUS. THE GEFS AND EUROPEAN ENSEMBLE MEAN ARE MUCH WEAKER
WITH THIS FEATURE THAN THE CANADIAN ENSEMBLE MEAN, AND ARE THE PREFERRED
SOLUTION BASED ON A PREPONDERANCE OF THE GUIDANCE. THE STRONG ANOMALOUS RIDGES
NEAR THE DAVIS STRAIT AND IN THE NORTH PACIFIC LOOK TO WEAKEN SOME, BUT AREN’T
EXPECTED TO HAVE MOVED MUCH. THIS MAINTAINS ABNORMALLY HIGH 500-HPA HEIGHTS
OVER MOST OF ALASKA (ESPECIALLY THE SOUTHERN TIER) IN THE GEFS AND CANADIAN
ENSEMBLE MEANS. THE EUROPEAN ENSEMBLE MEAN SHOWS A SIGNIFICANT MID-LEVEL TROUGH
APPROACHING ALASKA FROM THE WEST, BRINGING 500-HPA HEIGHTS DOWN TO NEAR NORMAL
BY THE END OF THE PERIOD. AT THIS TIME, A SOLUTION SIMILAR TO THE GEFS AND
CANADIAN ENSEMBLE MEANS IS FAVORED BASED ON A PREPONDERANCE OF THE TOOLS, WHICH
KEEP ANOMALOUS MID-LEVEL RIDGING ACROSS MOST OF ALASKA. THIS CONFIGURATION
WOULD RESULT IN AN UNUSUALLY STRONG MID-LEVEL JET STRETCHED WEST-TO-EAST ACROSS
THE STATE.
THE DYNAMIC MODELS ARE SOMEWHAT MORE CONSISTENT WITH EACH OTHER THAN YESTERDAY,
BUT THE RAW AND DERIVED TEMPERATURE AND PRECIPITATION FORECASTS BASED ON THE
ENSEMBLES REMAIN SIGNIFICANTLY INCONSISTENT. THE 6- TO 10-DAY TEMPERATURE
FORECASTS HIGHLIGHT THE SITUATION WELL. RESULTS FROM THE BIAS-CORRECTED
ENSEMBLE OUTPUT AND THE REFORECASTS ARE IN SOME CASES SHARPLY DIFFERENT FROM
THE RAW MODEL OUTPUT. RAW TEMPERATURE OUTPUT FROM THE GEFS, EUROPEAN ENSEMBLE
MEAN, AND CANADIAN ENSEMBLE MEAN ARE BROADLY SIMILAR, WITH BELOW-NORMAL
TEMPERATURES FORECAST FROM THE CENTRAL AND SOUTHERN APPALACHIANS THROUGH THE
MISSISSIPPI VALLEY, IN THE SOUTHERN PLAINS, AND IN MOST AREAS FROM THE ROCKIES
WESTWARD. BIAS-CORRECTIONS, HOWEVER, RESULT IN A MORE DIVERSE SET OF RESULTS.
THE GEFS CHANGES LITTLE WHILE THE EUROPEAN BIAS-CORRECTION SIGNIFICANTLY RAISES
TEMPERATURES ACROSS MOST OF THE CONUS. THE CANADIAN ENSEMBLE BIAS CORRECTION
ALSO WARMS THE CONUS, BUT NOT TO THE DEGREE NOTED IN THE EUROPEAN. THE
REFORECAST TEMPERATURES THROW MORE UNCERTAINTY INTO THE MIX, BEING EVEN WARMER
THAN THE BIAS CORRECTIONS. THIS IS MOST DRAMATIC IN THE GEFS, WHERE THE
REFORECASTS SHOW MUCH OF THE CONUS WARMER THAN NORMAL, IN OPPOSITION TO THE
GEFS RAW OUTPUT. SIMILAR ISSUES CAN BE SEEN IN THE PRECIPITATION TOOLS. GIVEN
THIS BROAD DISPARITY, THE OFFICIAL FORECAST REFLECTS A BLEND OF THE TOOLS,
LEANING TOWARD THOSE THAT APPEAR TO BEST AGREE WITH THE FORECAST SURFACE AND
MID-LEVEL WEATHER PATTERN, AND IN THE DIRECTION OF THE MOST RECENTLY OBSERVED
BIASES. THE DISPARITY ALSO LOWERS FORECAST CONFIDENCE, SO MOST AREAS TILT ONLY
SLIGHTLY IN THE DIRECTION OF ONE EXTREME, IF AT ALL.
CONSIDERING ALL THESE FACTORS, ABOVE-NORMAL TEMPERATURES ARE FAVORED ACROSS THE
GREAT BASIN AND ADJACENT PARTS OF THE WEST COAST, NORTHERN MAINE, AND SOUTHERN
FLORIDA. ONLY SMALL PARTS OF THE AREAS IN MAINE AND FLORIDA HAVE ODDS EXCEEDING
40 PERCENT FOR WARMER-THAN-NORMAL CONDITIONS. SUBNORMAL TEMPERATURES ARE
FAVORED ALONG AND NEAR THE MISSISSIPPI VALLEY AND ACROSS THE SOUTHERN TIER OF
THE CONUS FROM THE SOUTHERN ROCKIES TO THE CENTRAL GULF COAST. ODDS FOR COOLER
THAN NORMAL WEATHER EXCEED 40 PERCENT IN PARTS OF THE LOWER MISSISSIPPI VALLEY
AND SOUTHERN GREAT PLAINS, EXCEEDING 50 PERCENT IN PART OF THE BIG BEND. THIS
LEAVES A LARGE PROPORTION OF THE COUNTRY WITH NO TILT OF THE ODDS TOWARD EITHER
EXTREME, INCLUDING MOST OF THE ROCKIES AND PLAINS, AND MOST AREAS FROM THE
EASTERN GREAT LAKES AND APPALACHIANS TO THE EAST COAST.
SURPLUS PRECIPITATION IS ANTICIPATED ALONG THE GULF COAST AND THE EASTERN
SEABOARD IN ASSOCIATION WITH A SURFACE LOW PRESSURE AND FRONTAL SYSTEM MOVING
THROUGH THESE REGIONS EARLY IN THE PERIOD. SURPLUS PRECIPITATION IS ALSO
FAVORED IN THE NORTHERN AND SOUTHERN ROCKIES, AND NORTHERN INTERMOUNTAIN WEST.
MEANWHILE, DRIER THAN NORMAL WEATHER IS FAVORED ALONG THE CENTRAL WEST COAST
AND OVER A LARGE PART OF THE GREAT PLAINS, MISSISSIPPI VALLEY, AND LOWER OHIO
VALLEY. ONLY RELATIVELY SMALL SWATHS OF THE NORTHERN INTERMOUNTAIN WEST, LOWER
OHIO VALLEY, SOUTHEAST, AND NORTHEAST HAVE ODDS EXCEEDING 40 PERCENT IN EITHER
DIRECTION.
THE FORECAST PATTERN ACROSS ALASKA, WITH ANOMALOUSLY HIGH 500-HPA HEIGHTS IN
SOUTHERN AND CENTRAL ALASKA AND NEAR TO BELOW NORMAL HEIGHTS FARTHER NORTH,
FAVORS A STRONG WEST-TO-EAST MID-LEVEL JET STREAM ACROSS THE STATE. THIS SHOULD
RESULT IN SOMEWHAT MORE STORMINESS THAN NORMAL, WITH TEMPERATURES NOT DEVIATING
TOO FAR FROM NORMAL. A SLIGHT TILT TOWARD INCREASED CHANCES FOR BELOW-NORMAL
TEMPERATURES IS FAVORED OVER MUCH OF THE MAINLAND, WITH SLIGHTLY ABOVE-NORMAL
TEMPERATURES PREDICTED FOR THE ALEUTIANS AND NORTHEASTERN MAINLAND. IN A LARGE
PART OF THE CENTRAL AND WESTERN MAINLAND, ODDS FOR WETTER THAN NORMAL
CONDITIONS EXCEED 50 PERCENT.
A MID-LEVEL TROUGH NEAR HAWAII FAVORS COOLER AND WETTER THAN NORMAL CONDITIONS
THERE.
THE OFFICIAL 6-10 DAY 500-HPA HEIGHT BLEND CONSISTS OF 45% OF TODAY'S 6Z GFS
ENSEMBLE MEAN CENTERED ON DAY 8, 20% OF TODAY'S GFS SUPERENSEMBLE MEAN CENTERED
ON DAY 8, 20% OF TODAY'S 0Z EUROPEAN ENSEMBLE MEAN CENTERED ON DAY 8, AND 15%
OF TODAY'S 0Z CANADIAN ENSEMBLE MEAN CENTERED ON DAY 8
FORECAST CONFIDENCE FOR THE 6-10 DAY PERIOD: BELOW AVERAGE, 2 OUT OF 5, DUE TO
FAIR AGREEMENT ON THE PREDICTED CIRCULATION PATTERN, OFFSET BY MARKED DISPARITY
IN THE RAW AND DERIVED TEMPERATURE AND PRECIPITATION TOOLS FROM THE DYNAMIC
MODELS.
8-14 DAY OUTLOOK FOR APR 04 - 10 2024
THE WEEK-2 500-HPA HEIGHT FORECAST IS EXPECTED TO BE LESS PROGRESSIVE THAN
DURING THE 6- TO 10-DAY PERIOD, WITH 500-HPA ANOMALIES SHIFTING LITTLE BETWEEN
THE START AND THE END OF THE PERIOD. AN EXITING MID-LEVEL TROUGH SHOULD LEAVE A
WEAK 500-HPA RIDGE IN ITS WAKE ACROSS THE EASTERN CONUS WHILE A MID-LEVEL
TROUGH IS REINFORCED IN THE WESTERN CONUS, ALTHOUGH A FEW INDIVIDUAL SHORTWAVES
WILL EJECT FROM THE MEAN TROUGH TOWARD THE CENTRAL AND EASTERN CONUS. AT HIGHER
LATITUDES, ANOMALOUS RIDGING IS EXPECTED TO PERSIST NEAR THE DAVIS STRAIT AND
IN THE NORTH PACIFIC OCEAN.
THE UNCERTAINTY RESULTING FROM THE RAW AND DERIVED TEMPERATURE AND
PRECIPITATION TOOLS CARRIES INTO WEEK-2, BUT WITH THE LESS PROGRESSIVE PATTERN,
THEY END UP IN BETTER AGREEMENT THAN DURING THE 6-10 DAY PERIOD. A MEAN
MID-LEVEL RIDGE IN THE EASTERN CONUS FAVORS ABOVE-NORMAL TEMPERATURES ACROSS A
LARGE PART OF THE EASTERN GREAT PLAIN, MISSISSIPPI AND OHIO VALLEYS, UPPER
SOUTHEAST, GREAT LAKES, AND NORTHERN APPALACHIANS. WARMER THAN NORMAL WEATHER
IS ALSO EXPECTED IN SOUTHERN FLORIDA. MEANWHILE, THE MEAN MID-LEVEL TROUGH
IMPLIES COOLER THAN NORMAL WEATHER FROM THE ROCKIES WESTWARD. ENHANCED CHANCES
FOR SUBNORMAL TEMPERATURES EXCEED 50 PERCENT ALONG THE WEST COAST STATES AND IN
THE NORTHERN INTERMOUNTAIN WEST. THESE ODDS ARE GREATER THAN THOSE FOR EITHER
EXTREME DURING THE 6- TO 10-DAY PERIOD, OUTSIDE A SMALL PART OF THE BIG BEND.
WITH THE MEAN TROUGH IN THE WEST EJECTING OCCASIONAL SHORTWAVES TOWARD THE
MID-LEVEL RIDGE IN THE EAST, UNDER CYCLONIC MID-LEVEL FLOW, ABOVE-NORMAL
PRECIPITATION IS FAVORED OVER MUCH OF THE CONUS FROM THE INTERMOUNTAIN WEST TO
THE APPALACHIANS AND SOUTH ATLANTIC STATES. INCREASED ODDS FOR DRIER THAN
NORMAL CONDITIONS ARE RESTRICTED TO MUCH OF NEW ENGLAND.
THE UNUSUALLY STRONG WEST-TO-EAST MID-LEVEL JET ACROSS ALASKA IS FORECAST TO
CONTINUE THROUGH WEEK-2. ENHANCED ODDS FOR ABOVE-NORMAL PRECIPITATION CONTINUE
THROUGH MOST OF THE STATE, ALONG WITH INCREASED CHANCES FOR NEAR- TO
ABOVE-NORMAL TEMPERATURES, AS THE CIRCULATION PATTERN GENERALLY PRECLUDES
INTRUSIONS OF UNUSUALLY COLD OR WARM AIR FROM OTHER PARTS OF THE GLOBE.
CONTINUED BELOW-NORMAL 500-HPA HEIGHTS, REPRESENTING A CONTINUING WEAK
MID-LEVEL TROUGH, FAVOR COOLER AND WETTER THAN NORMAL CONDITIONS AGAIN FOR
WEEK-2 ACROSS HAWAII.
THE OFFICIAL 8-14 DAY 500-HPA HEIGHT BLEND CONSISTS OF: 45% OF TODAY'S 6Z GFS
ENSEMBLE MEAN CENTERED ON DAY 11, 20% OF TODAY'S GFS SUPERENSEMBLE MEAN
CENTERED ON DAY 11, 20% OF TODAY'S 0Z EUROPEAN ENSEMBLE MEAN CENTERED ON DAY
11, AND 15% OF TODAY'S 0Z CANADIAN ENSEMBLE MEAN CENTERED ON DAY 11
FORECAST CONFIDENCE FOR THE 8-14 DAY PERIOD: NEAR AVERAGE, 3 OUT OF 5, WITH THE
TEMPERATURE AND PRECIPITATION TOOLS COMING INTO BETTER AGREEMENT THAN DURING
THE 6- TO 10-DAY PERIOD, ALONG WITH FAIR AGREEMENT AMONG MODEL FORECASTS OF THE
WEEK-2 MEAN 500-HPA HEIGHT PATTERN.

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
APRIL 18.
