Read off the Climate Prediction Center’s own outlook polygons for Nevada, issued October 15, 2026. The outer 33% contour is the boundary of the shaded area, where the odds sit close to even and only the direction is on the map. On the edge of the tilt means the state straddles two probability bands, so one part of it carries the higher number.

A seasonal outlook is a probability, never a promise. NOAA’s Climate Prediction Center issued the March to May 2027 outlook on October 15, 2026 and shifts the odds between three categories, warmer than normal, near normal and cooler than normal, measured against 1991 to 2020. Equal chances means the outlook has no usable signal there.

The melt

The Nevada snowpack, and when it comes off

Spring in Nevada is a question about water before it is a question about warmth. These are the dates the USDA snow network’s 58 Nevada stations normally peak and melt out, and the live reading underneath is where the pack stands against its own median for today.

  • March 28the median date the pack peaks across 58 stations
  • May 9the median date those stations melt out
  • 13.1 inmedian snow water equivalent at the peak
  • Mt Rose Ski Areadeepest station at peak, 37.4 inches at 8,810 feet

The pack is the water supply and the flood risk in one number. It melts from the bottom of the elevation band up, so a valley can be bare while Cave Mountain at 10,580 feet is still holding its snow, and a warm rain on a standing pack adds its own water to what it melts. The National Weather Service office in Las Vegas, NV issues the spring flood outlooks for Nevada.

The live pack reading loads here.

The window

How risky an early warm spell is in Nevada

A warm spell in March costs nothing by itself. It costs something when it pulls buds and blossom out ahead of the last freeze, because once a plant has broken dormancy the same 28 F night it shrugged off in February takes the crop. The two dates below are both normals, and the distance between them is the exposure.

Mar 7normal first leaf66 daysMay 12median last freeze

A wide exposed window. Leaf-out normally runs more than five weeks ahead of the last likely freeze.

In Nevada the USA National Phenology Network’s Spring Leaf Index normally fires on March 7, and the freeze normals put the coin flip at May 12, with a 1 in 10 chance of a freeze still ahead on June 11. That gap is how long plants are normally out while a freeze is still on the table: 66 days to the coin flip, 96 to the 1 in 10 date. Both ends are published normals for 1991 to 2020. Neither is a forecast.

The last freeze

When the last frost normally ends in Nevada

Every date here is a 1991 to 2020 normal, which means it is what the station did over 30 years and not what it will do in 2027. The 1 in 10 column is the one a tender crop plants against.

What spring does here

Spring hazards in Nevada

  • Snowmelt and runoff

    Nevada’s mountain snow normally reaches its deepest around March 28 and is normally gone by May 9, read across 58 snow stations. How fast that water leaves depends on how warm the melt weeks run and whether rain falls on the pack. Las Vegas, NV issues the hydrologic and flood statements for this ground.

  • A warm spell, then a freeze

    Leaf-out normally happens around March 7 in Nevada, and a freeze still has an even chance of coming after it until about May 12. That is 66 days of plants being out while a freeze is still on the table, which is what makes an early warm spell here expensive rather than welcome.

  • A deficit going into spring

    On the Drought Monitor map for August 25, 2026, 90 percent of Nevada was in moderate drought or worse, and 45 percent in severe drought or worse. Spring rain fills that hole before it does anything else, so a near normal spring can still leave the ground short.

  • Spring arrives at different times inside the state

    Across 107 NOAA stations in Nevada, Laughlin normally sees its last freeze by January 5 while Jiggs 2NE at 5,642 feet normally waits until June 16. That is 162 days between two ends of the same state.

  • A wet tilt, and what it costs

    CPC tilts March to May 2027 precipitation wet over Nevada at 40 percent odds. A wet spring is a late spring for anyone working soil: ground that holds water stays cold and stays unworkable, whatever the air temperature does. The statewide median last freeze is around May 12, and wet ground can hold planting past it.

Drought figures are the United States Drought Monitor map for August 25, 2026. Flood and snowmelt outlooks for Nevada are issued by the National Weather Service office in Las Vegas, NV.

Planting

When planting starts in Nevada

We'll tell you the earliest dates to plant vegetables in the spring and the last dates that you can plant for a fall harvest, based on average frost dates for the Reno area.

Counting from Nevada’s statewide median last freeze of May 12, cool season seed goes in while the soil is at 50 F and warm season transplants wait for 60 F. The live reading above gives the soil temperature for your own ZIP at the depth the guides use.

The research

What decides how early spring arrives

Four things move the reading at the top of this page. The forecast hub carries all of them with every quote behind them, including the snowpack and the drought.

The March to May temperature outlook

CPC’s official call on the season spring happens in. A warm tilt moves leaf-out and the last freeze earlier; equal chances move nothing.

  • The temperature outlook holds its winter shape into spring, so the March to May map is not a new pattern but the winter one carried forward.

    The evolution of the Temperature Outlooks from Dec-Jan-Feb (DJF) 2026-2027 through MAM 2027 maintain the NDJ forecast pattern in large order and are consistent with strong El Nino events through these seasons with additional attention paid to some of the historically strong events.

  • A white area on the outlook map is not a forecast of normal. It means the three categories are near their climatological odds and the outlook has no usable signal there.

    Equal chances (EC, white areas) are forecast for areas where probabilities for each category of seasonal mean temperatures and accumulated precipitation amounts are forecast to be similar to climatological probabilities.

  • CPC writes these outlooks to be read before the season starts, which is what makes a spring outlook read in autumn the right document and not a stale one.

    These climate outlooks are intended for use prior to the start of their valid period.

The ENSO state

An El Nino advisory is in effect and favored to hold through spring. It is the reason the outlook maps look the way they do, and it tilts odds rather than setting outcomes.

  • CPC has an El Nino advisory in effect and favors the event continuing through spring 2027, which is why the spring outlook looks the way it does.

    The ongoing El Nino event continues to strengthen, and an El Nino advisory remains in effect and is favored to continue through Spring 2027.

  • CPC puts an 80 percent chance on at least a strong El Nino holding through January to March, and favors an El Nino of some strength through March to May 2027.

    The official CPC ENSO Outlook forecasts high probabilities (80%) for at least a strong El Nino event to continue through the Jan-Feb-Mar (JFM) 2027 season and favors an El Nino event of any strength to continue through the Mar-Apr-May (MAM) 2027.

  • The advisory puts the chance of a strong to very strong El Nino through January to March above 83 percent.

    El Niño continues to strengthen, with a strong-to-very strong El Niño likely through January-March 2027 (remaining greater than an 83% chance).

  • A strong event raises the odds of the usual El Nino outcomes without guaranteeing any of them, which is the whole reason a tilt is not a forecast.

    With an event of this magnitude, the chances of experiencing impacts consistent with El Niño are larger, though not guaranteed (see CPC outlooks for probabilities of seasonal anomalies).

  • In an El Nino the storm track sits south of mainland Alaska, which is the mechanism behind the dry tilt there.

    The Pacific Jet is shifted southward and eastward during El Nino events and so the storm track and associated precipitation tends to be located south of most of mainland Alaska.

A pack holding the ground cold

Snow cover keeps the air above it cool and pushes warming later, which is a brake on spring the temperature outlook does not carry on its own.

  • Widespread snow cover keeps the air above it cooler and pushes spring warming later, then makes the melt faster when it comes.

    Also, when snow cover is widespread, it usually keeps air temperatures cooler and delays spring warming, which increases the potential for more rapid snowmelt.

  • A snowpack is water held in place until the thaw, so a spring that starts with a deep pack starts with its runoff already banked.

    Unlike rainfall that can reach the soil almost immediately, the snowpack can store the water for an extended amount of time until temperatures rise above freezing and the snow melts.

The gap between leaf-out and the last freeze

Both ends are published normals for the same 30 years, so the days between them are a climatology of how long plants are normally out while a freeze is still likely.

  • The First Leaf and First Bloom Indices are modeled from recent temperatures, not counted from observed plants, so a date from them is a model output.

    The First Leaf and First Bloom Indices are synthetic measures of these early season events in plants, based on recent temperature conditions.

  • The indices exist to follow spring moving across the country, which is what makes a normal leaf-out date comparable between states.

    These models allow us to track the progression of spring onset across the country.

  • The Late Bloom Index marks the tail of the season, so a state has a modeled start and a modeled end to its spring.

    The Late Bloom Index indicates when plants that bloom at the tail end of the season are flowering, effectively representing the end of the spring season.

  • NCEI describes its normals as a ruler for today and a predictor of the near future, which is exactly the job a last freeze date does.

    Normals act both as a ruler to compare today’s weather and tomorrow’s forecast, and as a predictor of conditions in the near future.

  • The normals come from a uniform 30 year period across almost 15,000 stations, which is why a station a county away can carry a different last freeze date.

    The official normals are calculated for a uniform 30 year period, and consist of annual/seasonal, monthly, daily, and hourly averages and statistics of temperature, precipitation, and other climatological variables from almost 15,000 U.S. weather stations.

  • Every tilt is measured against the 1991 to 2020 period, the same 30 years the frost dates and spring indices on these pages use.

    The Climatic normals are based on conditions between 1991 and 2020, following the World Meterological Organization convention of using the most recent 3 complete decades as the climatic reference period.

Spring forecasts in other states

The March to May 2027 outlook was issued by NOAA’s Climate Prediction Center on October 15, 2026 and shifts the odds between three categories. It is a probability, never a promise. Freeze and frost dates come from NOAA NCEI U.S. Climate Normals 1991-2020, annual/seasonal, by station (v1.0.1), a 30 year average rather than a forecast for one year. Live readings come from the National Weather Service forecast for the ZIP you enter, and the Las Vegas, NV office issues the warnings that govern.
