NYC May 14 Low Temp: Will 54-55°F Hit?

Spring in New York City is a forecaster’s headache. The overnight low on May 14 could land anywhere across a 20-degree range, and right now one narrow band is drawing the most trader attention. The 54-55°F outcome sits at 31.5% implied probability, a meaningful jump after a 9% price move in the last 24 hours. The market is pricing uncertainty, not science, and the science here is genuinely uncertain.

Total trading volume stands at $1,601 with $752 changing hands in the last 24 hours. Liquidity sits at $7,929. Those are thin numbers. At this volume level, a single new forecast update or a shift in the National Weather Service model run can move price sharply before the 2026-05-14 12:00:00 resolution window closes.

How the May 14 NYC Low Temperature Contract Works

This contract resolves based on the official lowest temperature recorded in New York City on May 14, 2026. The National Weather Service Central Park station is the standard reference point for NYC temperature records. A YES on the 54-55°F outcome pays out if the overnight low falls within that two-degree band. Every other temperature range is a competing outcome.

• 54-55°F (primary outcome): YES at $0.32 / 31.5% implied probability
• 56-57°F: competing outcome
• 52-53°F: competing outcome
• 50-51°F: competing outcome
• 58-59°F: competing outcome
• 60-61°F: competing outcome
• 48-49°F: competing outcome
• 46-47°F: competing outcome
• 62-63°F: competing outcome
• 45°F or below: competing outcome
• 64°F or higher: competing outcome

The NO side of this contract wins if the May 14 overnight low lands anywhere outside the 54-55°F window. That is ten competing outcomes. The National Weather Service’s 48-hour model guidance, particularly the GFS and NAM short-range runs, will be the most reliable signal as the resolution date approaches. A warmer-than-expected airmass pushing overnight lows above 57°F, or a late cold intrusion pulling temperatures below 52°F, both send this contract to zero.

Momentum and Market Signals

The 24-hour price gain of 9.0% combined with a trend score of 30.87 and flat 1-hour movement suggests a single catalyst pushed price upward and traders have since held their positions. The most likely driver is a recent National Weather Service model run placing the May 14 overnight low closer to the 54-55°F corridor, with subsequent guidance confirming that range. Price has stabilized since the jump, which typically means the market is waiting for the next forecast update rather than acting on new information.

The $1,601 total volume and $7,929 liquidity are both low. This is a thin market. A single large trade of a few hundred dollars can reprice the contract by several percentage points. The 24-hour volume of $752 suggests active but small participation. Treat the current 31.5% probability as directionally meaningful but not deeply liquid-verified conviction.

• 1h change: flat (0.0%). The market has absorbed the 24-hour move and is waiting on fresh NWS guidance.
• 24h change: +9.0%. A meaningful single-session gain pointing to updated forecast models favoring the 54-55°F band.
• Trend score: 30.87. Moderate upward momentum, not a runaway signal.
• Volume at $1,601 total. Thin liquidity means new NWS model runs in the next 36 hours carry outsized price impact.
• Ten competing outcomes. Even at 31.5%, this is the leading band. No single alternative outcome commands majority probability.

Lines Analysis: What the NWS Data Is Telling Us

Here’s what the measurements are telling us. May 14 overnight lows in New York City historically cluster in the 50-60°F range during mid-May, with the climatological average overnight low for mid-May at Central Park sitting in the low-to-mid 50s. The 54-55°F band is genuinely the modal outcome based on historical frequency. That is why the market has assigned it the highest single probability even while holding the NO side above two-thirds.

The risk to the 54-55°F outcome is real and comes from both directions. A stronger-than-forecast ridging pattern over the Northeast could push lows into the 58-62°F range, eliminating this contract entirely. Conversely, a late-season cold front arrival ahead of schedule could pull temperatures into the 50-53°F corridor. The National Weather Service’s 72-hour deterministic runs and the ensemble mean will signal which risk is materializing. Neither direction looks dominant at this writing, which explains why the market has settled around 31.5% rather than moving sharply toward or away from YES.

Signals to monitor before resolution:

• National Weather Service 48-hour forecast for Central Park overnight low: the single most important number. Any NWS guidance landing below 53°F or above 56°F directly reprices this contract.
• GFS and NAM model agreement on May 13 overnight temperatures: divergence between models signals higher forecast uncertainty and could suppress the YES price even if the mean sits at 54-55°F.
• NOAA ensemble spread for the May 14 overnight window: a tight ensemble spread around 54-55°F would be a bullish signal for YES. A wide spread is bearish for any specific band.
• Observed high temperature on May 13: warmer-than-forecast daytime highs often signal a warmer overnight floor, pushing the distribution toward the 56-57°F or 58-59°F bands.
• Surface frontal analysis from NWS New York: any cold front timing shift of six hours or more can move the overnight low by two to four degrees.

The $1,601 in total volume reflects a market that has found a tentative equilibrium. The data currently supports the 54-55°F band as the most likely single outcome. That is not the same as saying YES is likely. With ten competing outcomes and thin liquidity, the market is pricing a probability distribution, not a consensus call.

LINES VERDICT

Narrow Leader, Crowded Field

The 54-55°F band holds the leading position in a highly fragmented market, supported by mid-May climatology and recent forecast model movement. With ten competing outcomes and thin volume, no single band commands strong conviction.

What the market says: 31.5% probability means traders see the 54-55°F band as the most likely single outcome but still assign nearly a 70% chance the overnight low lands somewhere else entirely. The thin liquidity means this price can shift sharply on any NWS model update before the 2026-05-14 12:00:00 resolution.

Key unknown: The National Weather Service 48-hour deterministic forecast for Central Park overnight low on May 14 is the single data point that will reprice this contract. Any guidance landing outside the 53-56°F range moves probability mass away from this outcome immediately.

Scientific Context

New York City’s mid-May temperature climatology is well-documented by NOAA. The Central Park station, one of the longest continuous urban temperature records in the United States, shows overnight lows in the 50-60°F range as the dominant May 14 historical distribution. The 54-55°F band sits near the center of that range. Urban heat island effects keep NYC overnight lows consistently warmer than surrounding suburban and rural stations, which matters when evaluating ensemble model output calibrated to broader regional grids. The market price of 31.5% is consistent with the climatological frequency of that specific two-degree band appearing as the overnight minimum. No recent NOAA climate anomaly data or NWS special statements would materially shift the base rate before the resolution date.

Frequently Asked Questions

• What does 31.5% probability mean here? The market assigns a roughly one-in-three chance that NYC’s official overnight low on May 14 falls specifically between 54 and 55 degrees Fahrenheit, as measured at the National Weather Service Central Park station.
• What does the NO side represent? The NO contract covers all nine other temperature bands plus any reading outside the defined ranges. Any overnight low below 53°F or above 55°F resolves this specific outcome as NO.
• What data event would move this price the most? The National Weather Service 48-hour forecast issued on May 12 or May 13 carries the most weight. A forecast low outside the 53-56°F range would sharply reprice the YES contract.
• When does this market resolve? Resolution closes at 2026-05-14 12:00:00, based on the official overnight low recorded by the National Weather Service for New York City on May 14.
• Is the $1,601 volume reliable enough to trust the price? Volume this thin means the 31.5% probability is directionally informative but not deeply tested. A few hundred dollars of new trading can move price by several percentage points before resolution.
