PROGNOSTIC DISCUSSION FOR LONG-LEAD SEASONAL OUTLOOKS
NWS CLIMATE PREDICTION CENTER COLLEGE PARK MD
830 AM EST THU FEB 19 2026
SUMMARY OF THE OUTLOOK FOR NON-TECHNICAL USERS
LA NIñA CONDITIONS ARE PRESENT, AS REPRESENTED IN CURRENT OCEANIC AND
ATMOSPHERIC OBSERVATIONS. A TRANSITION FROM LA NIñA TO ENSO-NEUTRAL IS
EXPECTED IN FEBRUARY-APRIL 2026 (60% CHANCE), WITH ENSO-NEUTRAL LIKELY
PERSISTING THROUGH THE NORTHERN HEMISPHERE SUMMER (56% CHANCE IN JUNE-AUGUST
2026).
THE MARCH-APRIL-MAY (MAM) 2026 TEMPERATURE OUTLOOK FAVORS ABOVE NORMAL
TEMPERATURES FOR SOUTHERN AND CENTRAL PORTIONS OF THE WESTERN CONTIGUOUS UNITED
STATES (CONUS), THE SOUTHERN AND CENTRAL PLAINS, THE LOWER AND MIDDLE
MISSISSIPPI VALLEY, THE TENNESSEE VALLEY, SOUTHEAST, AND SOUTHERN MID-ATLANTIC.
A TILT TOWARD ABOVE NORMAL TEMPERATURES IS ALSO INDICATED FOR NORTHWESTERN
ALASKA. THE HIGHEST PROBABILITIES (GREATER THAN 60 PERCENT) OF ABOVE NORMAL
TEMPERATURES ARE FORECAST ACROSS PARTS OF THE SOUTHWEST. BELOW NORMAL
TEMPERATURES ARE MODESTLY FAVORED FOR MUCH OF EASTERN ALASKA AND PARTS OF THE
WESTERN GREAT LAKES, UPPER MISSISSIPPI VALLEY, AND PARTS OF THE ADJACENT RED
RIVER VALLEY.
THE MAM 2006 PRECIPITATION OUTLOOK DEPICTS ENHANCED PROBABILITIES OF BELOW
NORMAL PRECIPITATION AMOUNTS ACROSS THE SOUTHERN TWO-THIRDS OF THE WESTERN
CONUS AND FOR ADJACENT AREAS OF THE CENTRAL AND SOUTHERN PLAINS. BELOW NORMAL
PRECIPITATION IS MODESTLY FAVORED FOR SOUTHEAST ALASKA AND ADJACENT AREAS OF
MAINLAND ALASKA. THE GREATEST CHANCES OF BELOW NORMAL PRECIPITATION (ABOVE 50
PERCENT PROBABILITY) ARE INDICATED FOR PARTS OF THE SOUTHWEST. ABOVE NORMAL
PRECIPITATION IS MORE LIKELY FOR THE GREAT LAKES, OHIO VALLEY, AND ADJACENT
AREAS OF THE MISSISSIPPI VALLEY. A TILT TOWARD ABOVE NORMAL PRECIPITATION IS
ALSO INDICATED FOR THE NORTHWEST COAST OF MAINLAND ALASKA. THE GREATEST CHANCES
OF ABOVE NORMAL PRECIPITATION (GREATER THAN 40 PERCENT) IS INDICATED ACROSS THE
CENTRAL GREAT LAKES.
EQUAL CHANCES (EC) ARE FORECAST FOR AREAS WHERE PROBABILITIES FOR EACH CATEGORY
OF SEASONAL MEAN TEMPERATURES AND SEASONAL ACCUMULATED PRECIPITATION AMOUNTS
ARE EXPECTED TO BE SIMILAR TO CLIMATOLOGICAL PROBABILITIES.
BASIS AND SUMMARY OF THE CURRENT LONG-LEAD OUTLOOKS

CURRENT ATMOSPHERIC AND OCEANIC CONDITIONS
LA NIñA CONTINUED IN JANUARY 2026, WITH BELOW-AVERAGE SEA SURFACE TEMPERATURES
(SSTS) OBSERVED IN THE EAST-CENTRAL EQUATORIAL PACIFIC OCEAN. THE LATEST WEEKLY
NIñO-3.4 INDEX VALUE WAS -0.7°C, WITH THE WESTERNMOST (NIñO-4) AND
EASTERNMOST (NIñO-1+2) INDICES AT -0.1°C AND 0.5°C, RESPECTIVELY. THE
EQUATORIAL SUBSURFACE TEMPERATURE INDEX (AVERAGE FROM 180°-100°W)
SIGNIFICANTLY INCREASED, REFLECTING THE STRENGTHENING AND EXPANSION OF
ABOVE-AVERAGE SUBSURFACE TEMPERATURES ACROSS THE PACIFIC OCEAN. ATMOSPHERIC
ANOMALIES WEAKENED DUE TO SUBSEASONAL VARIABILITY, BUT STILL REFLECTED ASPECTS
OF LA NIñA. LOW-LEVEL WESTERLY WIND ANOMALIES WERE PRESENT OVER THE WESTERN
EQUATORIAL PACIFIC, AND UPPER-LEVEL WESTERLY WIND ANOMALIES CONTINUED ACROSS
THE EAST-CENTRAL EQUATORIAL PACIFIC. SUPPRESSED CONVECTION WAS WEAKLY EVIDENT
NEAR THE DATE LINE AND OVER THE EQUATORIAL MARITIME CONTINENT, WITH ENHANCED
CONVECTION LOCATED OFF THE EQUATOR. THE TRADITIONAL AND EQUATORIAL SOUTHERN
OSCILLATION INDICES WERE POSITIVE. COLLECTIVELY, THE COUPLED OCEAN-ATMOSPHERE
SYSTEM REMAINED CONSISTENT WITH LA NIñA.
PROGNOSTIC DISCUSSION OF SST FORECASTS
THE NORTH AMERICAN MULTI-MODEL ENSEMBLE (NMME) AVERAGE, INCLUDING THE NATIONAL
CENTERS FOR ENVIRONMENTAL PREDICTION (NCEP) CLIMATE FORECAST SYSTEM VERSION 2
(CFSV2), FAVOR THE ONSET OF ENSO-NEUTRAL IN FEBRUARY-APRIL 2026. THE TEAM
CONSENSUS ALSO REFLECTS THIS OUTCOME, WITH ENSO-NEUTRAL PERSISTING THROUGH THE
NORTHERN HEMISPHERE SUMMER 2026. FOR THE LATE SUMMER AND BEYOND, THERE IS A
50-60% CHANCE OF EL NIñO FORMING, THOUGH MODEL UNCERTAINTY REMAINS
CONSIDERABLE AND FORECASTS MADE THIS TIME OF YEAR TEND TO HAVE LOWER ACCURACY.
IN SUMMARY, A TRANSITION FROM LA NIñA TO ENSO-NEUTRAL IS EXPECTED IN
FEBRUARY-APRIL 2026 (60% CHANCE), WITH ENSO-NEUTRAL LIKELY PERSISTING THROUGH
THE NORTHERN HEMISPHERE SUMMER (56% CHANCE IN JUNE-AUGUST 2026).
ACCORDING TO THE ENSO TEAM, THERE IS A 75% CHANCE OF A TRANSITION TO
ENSO-NEUTRAL CONDITIONS DURING JANUARY-FEBRUARY-MARCH (JFM) 2026. ENSO-NEUTRAL
CONDITIONS ARE LIKELY TO PERSIST THROUGH AT LEAST THE NORTHERN HEMISPHERE LATE
SPRING BEFORE POTENTIALLY SHIFTING TOWARD EL NINO IN THE SUMMER AND EARLY FALL
OF 2026. WHILE THE CHANCE OF EL NINO IS HIGHER THAN THE CHANCE OF ENSO-NEUTRAL
OR LA NINA FOR THOSE SEASONS, MODEL PREDICTIONS REMAIN UNCERTAIN DUE TO LOWER
FORECAST ACCURACY AS WE PROGRESS THROUGH THE SPRING MONTHS AND INTO SUMMER.
SOME LINGERING LA NINA INFLUENCE IS EXPECTED FOR FMA 2026, BUT THE POTENTIAL
INFLUENCE OF EL NINO LATER IN THE YEAR IS TOO UNCERTAIN TO DETERMINE AT THIS
TIME.
PROGNOSTIC TOOLS USED FOR U.S. TEMPERATURE AND PRECIPITATION OUTLOOKS
DYNAMICAL MODEL FORECASTS FROM THE NMME, THE CFSV2, AND THE COPERNICUS (C3S)
MULTI-MODEL ENSEMBLE SYSTEM WERE USED EXTENSIVELY FOR THE FIRST SIX LEADS WHEN
THEY ARE AVAILABLE, AS WAS THE OBJECTIVE, HISTORICAL SKILL-WEIGHTED
CONSOLIDATION AND CALIBRATION, BRIDGING, AND MERGING (CBAM) GUIDANCE, THAT
COMBINES BOTH DYNAMICAL AND STATISTICAL FORECAST INFORMATION. COMPOSITES
DERIVED FROM THE CURRENT AND FORECAST STATE OF ENSO WERE ALSO UTILIZED.
ANALYSIS OF ANTECEDENT CONDITIONS SUCH AS EXTRATROPICAL SEA SURFACE
TEMPERATURES, SNOW COVER ANOMALIES, AND SEA ICE EXTENT PLAYED WERE CONSIDERED
WHERE APPROPRIATE. AT LATER LEADS, DECADAL TRENDS IN TEMPERATURE AND
PRECIPITATION WERE INCREASINGLY RELIED UPON IN CREATING THE SEASONAL OUTLOOKS.
PROGNOSTIC DISCUSSION OF OUTLOOKS - MAM 2026 TO MAM 2027
TEMPERATURE
ONE OF THE MAJOR FORECAST CHALLENGES FOR THE UPCOMING SPRING IS INCORPORATING
THE EXPECTED TRANSITION FROM LA NIñA TO ENSO NEUTRAL CONDITIONS. COMPOSITES
DERIVED FROM THE RECENT AND FORECAST EVOLUTION OF ENSO GENERALLY FAVOR WARMTH
ACROSS MUCH OF THE WEST AND AN AXIS OF COLDER THAN NORMAL TEMPERATURES
STRETCHING FROM EASTERN ALASKA SOUTHEASTWARD TO PARTS OF THE NORTHERN TIER OF
THE CONUS. DYNAMICAL MODEL GUIDANCE IS MUCH WARMER BUT STILL REFLECTS A
RELATIVE MINIMA IN ABOVE NORMAL TEMPERATURE PROBABILITIES FROM EASTERN ALASKA
TO PORTIONS OF THE NORTH-CENTRAL AND NORTHEASTERN CONUS. WHILE THERE ARE LARGE
DISAGREEMENTS IN THE CATEGORY OF THE FORECAST PROBABILITIES, THE CONFIGURATION
OF THE OVERALL TEMPERATURE PATTERN IS CONSISTENT AMONG DYNAMICAL AND
STATISTICAL GUIDANCE. THE MAM OUTLOOK REPRESENTS A COMPROMISE BETWEEN THE TWO
SETS OF SOLUTIONS. IN GENERAL, THERE IS VERY GOOD AGREEMENT AMONG BOTH
STATISTICAL AND DYNAMICAL MODEL GUIDANCE ON FAVORING WARMTH ACROSS THE SOUTHERN
TWO-THIRDS OF THE WESTERN CONUS. PROBABILITIES OF ABOVE NORMAL TEMPERATURES
EXCEED 60 PERCENT ACROSS PARTS OF THE SOUTHWEST WHERE THE WARM SIGNAL WAS THE
STRONGEST. CONVERSELY, BELOW NORMAL TEMPERATURES ARE FAVORED FOR EASTERN ALASKA
AND FOR THE WESTERN GREAT LAKES, AND PARTS OF THE UPPER MISSISSIPPI VALLEY AND
ADJACENT AREAS OF THE RED RIVER VALLEY. THESE AREAS OF FAVORED BELOW NORMAL
TEMPERATURES ARE CONSISTENT WITH THE NORTHWEST TO SOUTHEAST AXIS OF REDUCED
ABOVE NORMAL TEMPERATURE PROBABILITIES REFLECTED IN BOTH STATISTICAL AND
DYNAMICAL MODEL GUIDANCE. ENHANCED PROBABILITIES OF BELOW NORMAL TEMPERATURES
WERE KEPT MODEST TO REFLECT THE DIFFERENCES BETWEEN THE COLDER STATISTICAL AND
WARMER DYNAMICAL MODEL GUIDANCE. UNCERTAINTY IS ALSO HIGH ACROSS THE EASTERN
HALF OF THE CONUS, WHERE STATISTICAL ENSO COMPOSITES REFLECT LESS CONFIDENCE IN
WARMTH RELATIVE TO MODEL GUIDANCE. NEVERTHELESS, MODESTLY ENHANCED
PROBABILITIES OF ABOVE NORMAL TEMPERATURES ARE INDICATED FROM THE SOUTHERN AND
CENTRAL PLAINS EASTWARD TO THE LOWER AND MIDDLE MISSISSIPPI VALLEY, TENNESSEE
VALLEY, GULF COAST, THE SOUTHEAST, AND PARTS OF THE ADJACENT MID-ATLANTIC,
WHERE MODEL GUIDANCE AND TREND SHOW RELATIVELY STRONG WARM SIGNALS. WESTERN
ALASKA IS ALSO AN AREA OF HIGH UNCERTAINTY DUE TO WEAK OR CONFLICTING GUIDANCE.
A WEAK TILT TOWARD ABOVE NORMAL TEMPERATURES IS INDICATED FOR NORTHWESTERN
ALASKA AND PARTS OF THE ALEUTIANS, FOLLOWING DYNAMICAL MODEL GUIDANCE AND
TRENDS.
FROM APRIL-MAY-JUNE (AMJ) THROUGH JUNE-JULY-AUGUST (JJA), A NOTABLE NORTHWARD
EXPANSION OF ENHANCED ODDS FOR ABOVE NORMAL TEMPERATURES IS FORECAST ACROSS THE
CONUS. ABOVE NORMAL TEMPERATURES ARE FAVORED FOR THE ENTIRE SOUTHERN TWO-THIRDS
OF THE CONUS IN AMJ AND OVERSPREAD THE ENTIRE CONUS BY JJA. THIS EXTENSIVE
COVERAGE OF INCREASED ABOVE NORMAL TEMPERATURE CHANCES IS SUPPORTED BY
DYNAMICAL MODEL GUIDANCE AND TRENDS, ESPECIALLY ACROSS THE WESTERN CONUS.
PROBABILITIES OF ABOVE NORMAL TEMPERATURES EXCEED 50 PERCENT ACROSS THE
SOUTHWEST AND ADJACENT GREAT BASIN WITH GREATER THAN 60 PERCENT CHANCE OF ABOVE
NORMAL TEMPERATURES NOTED FOR THE FOUR CORNERS. THE STRONGEST SIGNAL FOR WARMTH
SHIFTS NORTH ACROSS THE INTERIOR WEST DURING THE SUMMER WITH GREATER THAN 50
PERCENT CHANCES OF ABOVE NORMAL TEMPERATURES REACHING THE NORTHERN ROCKIES BY
JJA. THE CONSENSUS OF DYNAMICAL AND STATISTICAL GUIDANCE HAS A RELATIVELY
WEAKER WARM SIGNAL ACROSS THE EASTERN CONUS. THEREFORE, EC IS INDICATED IN THE
GREAT LAKES AND NORTHEAST IN AMJ. BY JJA, INCREASED CHANCES OF ABOVE NORMAL
TEMPERATURES ENVELOPS THE ENTIRE EAST FROM SOUTH TO NORTH BUT WITH ONLY
MODESTLY ENHANCED PROBABILITIES. UNCERTAINTY ABOUNDS ACROSS ALASKA BETWEEN AMJ
AND JJA AS WARM DYNAMICAL MODEL GUIDANCE CLASHES WITH COLDER ENSO COMPOSITES
AND WEAK TRENDS. EC IS INDICATED FOR THE MAJORITY OF THE STATE DURING SPRING
BEFORE YIELDING TO A TILT TOWARD WARM IN EASTERN AREAS AS THE COLD SIGNAL IN
THE ENSO STATISTICAL TOOLS BEGINS TO DIMINISH. BY JAS, A TRANSITION TO EL NIñO
BECOMES MORE LIKELY, INCREASING UNCERTAINTY IN THE FORECAST PATTERN.
STATISTICAL ENSO AND TREND GUIDANCE GENERALLY DEPICT LESS CONFIDENCE IN WARMTH
ACROSS THE CENTRAL CONUS AS WE APPROACH THE FALL AND BEYOND. EC IS INTRODUCED
TO PARTS OF THE SOUTHERN AND CENTRAL PLAINS AND ADJACENT AREAS OF THE
MISSISSIPPI VALLEY DURING JAS. THIS EC AREA EXPANDS ACROSS CENTRAL CONUS DURING
ASO AS UNCERTAINTY INCREASES. LARGE AREAS OF EC DOMINATE THE CENTRAL CONUS BY
DJF AND BEYOND. INCREASED CHANCES FOR ABOVE NORMAL TEMPERATURES ARE INDICATED
FOR BOTH THE WEST AND EAST COASTS OF THE CONUS FROM JAS THROUGH AT LEAST JFM
2027 OWING LARGELY TO RECENT TRENDS. ALASKA LEANS MOSTLY WARM FROM THE LATE
FALL THROUGH NEXT WINTER DUE TO A COMBINATION OF TRENDS AND STATISTICAL ENSO
GUIDANCE.
PRECIPITATION
THE MAM PRECIPITATION OUTLOOK FEATURES INCREASED CHANCES OF ABOVE NORMAL
PRECIPITATION FROM THE GREAT LAKES SOUTHWARD TO THE OHIO VALLEY AND AREAS OF
THE ADJACENT MISSISSIPPI VALLEY, GENERALLY CONSISTENT WITH A LA NIñA
SIGNATURE. THE GENERAL CONSENSUS OF DYNAMICAL AND STATISTICAL TOOLS SUPPORT
BELOW NORMAL PRECIPITATION FOR THE SOUTHERN TWO-THIRDS OF THE WEST AS WELL AS
MUCH OF THE ADJACENT CENTRAL AND SOUTHERN PLAINS. PROBABILITIES OF BELOW NORMAL
PRECIPITATION EXCEED 50 PERCENT ACROSS PARTS OF THE SOUTHWEST WHERE RECENT
TRENDS SHOW THE STRONGEST DRY SIGNAL. UNCERTAINTY IS HIGH ACROSS THE SOUTHEAST
DUE TO A DICHOTOMY BETWEEN DRIER DYNAMICAL MODEL GUIDANCE AND WETTER TRENDS.
THEREFORE EC IS INDICATED FOR THIS AREA. EC IS ALSO INDICATED ALONG THE
IMMEDIATE EAST COAST OWING TO WEAK SIGNALS AMONG DYNAMICAL MODEL GUIDANCE. EC
IS ALSO INDICATED FOR THE NORTHWESTERN CONUS AS ABOVE NORMAL PRECIPITATION IS
FAVORED IN THE MONTHLY OUTLOOK FOR MARCH BUT THEN THE GUIDANCE TRENDS DRIER
DEEPER INTO SPRING. DYNAMICAL MODEL GUIDANCE IS IN GENERALLY GOOD AGREEMENT IN
SUPPORTING BELOW NORMAL PRECIPITATION ACROSS SOUTHEAST ALASKA AND ADJACENT
AREAS OF THE MAINLAND. A TILT TOWARD ABOVE NORMAL PRECIPITATION IS INDICATED
FOR THE WEST COAST OF THE MAINLAND, CONSISTENT WITH THE C3S, CBAM, AND TREND.
HOWEVER, PROBABILITIES WERE KEPT MODEST DUE TO RELATIVELY WEAK SIGNALS AND LACK
OF SUPPORT FROM THE REMAINDER OF THE SUITE OF STATISTICAL AND DYNAMICAL MODEL
GUIDANCE.
AS THE INFLUENCES OF LA NIñA WANE DEEPER INTO SPRING, THE AREA OF ELEVATED
ABOVE NORMAL PRECIPITATION CHANCES OVER THE GREAT LAKES DIMINISHES
SUBSTANTIALLY IN AMJ AND IS REMOVED ENTIRELY BY MJJ. A DRY SIGNAL EMERGES
ACROSS PARTS OF THE WESTERN GREAT LAKES AND UPPER MISSISSIPPI VALLEY FROM MJJ
TO JJA AND MIGRATES WESTWARD TO THE NORTHERN PLAINS DURING JAS, DRIVEN LARGELY
BY TRENDS. CONVERSELY, A NEW AREA OF INCREASED ABOVE NORMAL PRECIPITATION
CHANCES EMERGES ACROSS THE SOUTHEAST BY AMJ, DRIVEN PRIMARILY BY THE CBAM AND
TREND. THIS WET SIGNAL MIGRATES NORTHWARD ALONG THE EAST COAST DURING MJJ AND
JJA, WITH SUPPORT FROM DYNAMICAL MODEL GUIDANCE. THIS WET SIGNAL SLOWLY
DIMINISHES TO THE MID-ATLANTIC AREA AND ADJACENT AREAS OF THE APPALACHIANS BY
SON AS CONFIDENCE DECREASES. FARTHER TO THE SOUTH, A DRY SIGNAL DEVELOPS OVER
THE FLORIDA PENINSULA FROM JAS THROUGH SON, PEAKING IN COVERAGE DURING ASO,
POSSIBLY RESULTING FROM AN EMERGING EL NIñO AND ASSOCIATED REDUCED TROPICAL
ACTIVITY. FURTHER TO THE WEST, DYNAMICAL MODELS AND TRENDS GENERALLY SUPPORT A
NORTHWARD PROGRESSION OF FAVORED DRYNESS FROM THE GREAT BASIN AND CENTRAL
ROCKIES TO THE NORTHERN ROCKIES FROM AMJ THROUGH JAS. A PERSISTENT DRY SIGNAL
IS NOTED EASTWARD TO THE CENTRAL PLAINS FROM AMJ THROUGH JJA FROM THE C3S AND
CBAM, WITH SOME SUPPORT FROM TRENDS. BY MJJ, AN ENHANCED MONSOON SIGNAL EMERGES
ACROSS PARTS OF THE SOUTHWEST, SUPPORTED BY THE CFSV2, C3S, AND THE CBAM. THIS
ENHANCED MONSOON SIGNAL, WOULD BE CONSISTENT WITH DRYNESS IN THE PLAINS, AS THE
PRECIPITATION PATTERN TENDS TO BE ANTICORRELATED BETWEEN THESE TWO REGIONS.
SLIGHTLY ELEVATED PROBABILITIES OF ABOVE NORMAL PRECIPITATION ARE FORECAST TO
PERSIST FROM MJJ THROUGH ASO FOR PARTS OF THE SOUTHWEST, RELATED TO THE
POTENTIAL OF AN ENHANCED MONSOON. ACROSS ALASKA, SLIGHTLY ELEVATED
PROBABILITIES OF ABOVE NORMAL PRECIPITATION PERSIST FROM AMJ THROUGH JJA,
INITIALLY SUPPORTED BY THE C3S AND THE FINAL CONSOLIDATION DURING AMJ AND THEN
BY TREND FROM MJJ TO JJA . THEREAFTER, ABOVE NORMAL PRECIPITATION IS FAVORED
ACROSS SOUTHWESTERN MAINLAND ALASKA DURING JAS AND SPREADING EASTWARD ALONG THE
SOUTH COAST BY ASO, SUPPORTED BY ENSO COMPOSITES, TREND, AND THE CBAM. THE
FORECAST FOR LONGER LEAD TIMES LATER NEXT FALL, WINTER, AND EARLY SPRING 2027
ARE INFORMED MOSTLY BY TREND. THESE LONGER LEADS ARE CHARACTERIZED BY SLIGHT
TILTS TOWARD ABOVE NORMAL PRECIPITATION INITIALLY ALONG THE EAST COAST DURING
NDJ AND THEN MIGRATING NORTHWARD AND WESTWARD TOWARD THE NORTHEAST, GREAT
LAKES, AND OHIO VALLEY FROM DJF THROUGH FMA, AND EVENTUALLY TO THE UPPER
MISSISSIPPI VALLEY DURING MAM 2027. FARTHER TO THE WEST, A SLIGHT TILT TOWARD
BELOW NORMAL PRECIPITATION IS NOTED ACROSS THE CENTRAL PLAINS DURING ASO
MIGRATING NORTHEASTWARD TO THE UPPER MISSISSIPPI VALLEY DURING SON. WEAK TILTS
TOWARD ABOVE NORMAL PRECIPITATION PERSIST ACROSS PARTS OF THE SOUTH COAST AND
NORTH SLOPE OF ALASKA DURING THE LONGER LEADS.
