The European model is the outlier, six degrees above the next tool, and the range without it is 10.5\u00b0F. The reason for the large spread is uncertainty in how long the coastal low clouds hold on. The National Weather Service office serving Los Angeles describes the setup in their <a href=\"https:\/\/forecast.weather.gov\/product.php?site=LOX&amp;issuedby=LOX&amp;product=AFD\">forecast discussion<\/a>. They note seasonably warm weather away from the immediate coast, far interior areas continuing to bake under triple-digit temperatures all week, and low clouds with locally dense fog developing along the coast that could linger into the afternoon in some areas. Just exactly how long it lingers will decide the high. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Note: uncertainty in day-ahead temperatures corresponds to <a href=\"https:\/\/www.interactivebrokers.com\/campus\/traders-insight\/ibkr-climate-energy\/energy-expenditure-implications-of-next-day-temperature-forecasts\/\">significantly different energy use and expenditure across metro areas<\/a>, which can inform operating and financial considerations for various entities involved in energy.

Raw physical models are flexible and can handle weather situations they have never seen (they are not explicitly trained on historical data but rather adhere to the laws of physics), but forecasts apply to a relatively large discrete grid box that contains the <a href=\"https:\/\/data.forecastex.com\/regulatory\/UTermsandConditions.pdf\">weather station<\/a> rather than the single point where the station sits, causing them to carry systemic biases relative to the stations.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The <a href=\"https:\/\/vlab.noaa.gov\/web\/mdl\/lamp\">Aviation Forecast<\/a> is a <a href=\"https:\/\/en.wikipedia.org\/wiki\/Model_output_statistics\">model output statistics<\/a> system.

It lists a ladder of contracts at different strikes, and each price is the ForecastEx probability that the day&#8217;s extreme passes that strike. Comparing ForecastEx with the other systems therefore requires converting that ladder into a central estimate. The 50 percent level is the ForecastEx implied median, so where two adjacent listed strikes bracket that crossing, the central value is interpolated between them. Where the ladder does not bracket 50 percent, because every listed strike sits far in or far out of the money, no central value is recorded and ForecastEx is left unscored rather than extrapolated beyond the quoted ladder. That reflects how the strikes happened to be listed rather than anything about forecast quality, so it should count neither for nor against ForecastEx.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<h2 id=\"h-further-reading\" class=\"wp-block-heading\"><strong>Further Reading<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Prediction market basics<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><a href=\"https:\/\/www.interactivebrokers.com\/campus\/traders-insight\/ibkr-climate-energy\/the-value-of-climate-prediction-markets\/\">The Value of Climate Prediction Markets<\/a> \u2014 The case for why prediction markets can represent the best collective knowledge about our energy and climate future.<\/li>\n\n\n\n<li><a href=\"https:\/\/www.interactivebrokers.com\/campus\/traders-insight\/ibkr-climate-energy\/daily-high-temperature-markets-at-forecastex\/\">Daily High Temperature Markets at ForecastEx<\/a> \u2014 how the daily temperature contracts are built and settled.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Temperature markets and energy<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><a href=\"https:\/\/www.interactivebrokers.com\/campus\/traders-insight\/ibkr-climate-energy\/energy-expenditure-implications-of-next-day-temperature-forecasts\/\">Energy expenditure implications of next-day temperature forecasts<\/a> \u2014 what day-ahead temperature uncertainty costs utilities, energy traders and risk managers.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Hurricane and climate contracts<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><a href=\"https:\/\/www.interactivebrokers.com\/campus\/traders-insight\/securities\/esg\/hurricane-forecast-contracts\/\">Hurricane Forecast Contracts<\/a> \u2014 how the count and landfall contracts work.<\/li>\n\n\n\n<li><a href=\"https:\/\/www.interactivebrokers.com\/campus\/traders-insight\/ibkr-climate-energy\/disaster-insurance-applications-of-forecast-contracts\/\">Disaster Insurance Applications of Forecast Contracts<\/a> \u2014 using landfall contracts as parametric cover.<\/li>\n\n\n\n<li><a href=\"https:\/\/www.interactivebrokers.com\/campus\/traders-insight\/securities\/macro\/hurricane-forecast-contracts-as-a-diversifying-asset-in-an-investment-portfolio\/\">Hurricane Forecast Contracts as a Diversifying Asset in an Investment Portfolio<\/a> \u2014 correlation properties against conventional assets.<\/li>\n\n\n\n<li><a href=\"https:\/\/www.interactivebrokers.com\/campus\/traders-insight\/bundling-no-hurricane-landfall-forecast-contracts-to-reduce-downside-risk\/\">Bundling &#8220;NO&#8221; Hurricane Landfall Forecast Contracts to Reduce Downside Risk<\/a> \u2014 constructing a bundle across locations.<\/li>\n<\/ul>\n\n\n\n<h2 id=\"h-climate-contracts\" class=\"wp-block-heading\"><strong>Climate Contracts<\/strong><\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li><a href=\"https:\/\/www.interactivebrokers.com\/campus\/traders-insight\/securities\/commodities\/global-crop-yield-forecast-contracts\/\">Global Crop Yield Forecast Contracts<\/a> (<a href=\"https:\/\/www.interactivebrokers.com\/predictionmarkets\/app\/?utm_source=googlead&amp;utm_medium=paid_search&amp;utm_campaign=US_ForecastTrader_C&amp;utm_term=%22market+predictions%22&amp;utm_campaign_id=23792472669&amp;placement=search#\/786030244\/product-details\/contracts?exchange=FORECASTX&amp;conid_yes=810314078\">view here<\/a>).<\/li>\n\n\n\n<li><a href=\"https:\/\/www.interactivebrokers.com\/campus\/traders-insight\/securities\/esg\/how-quickly-will-the-globe-warm-paris-agreement-forecast-contracts\/\">How Quickly Will The Globe Warm?
