Temperature and precipitation trends in AccuWeather's 30-Day Forecast can help with Memorial Day planning.
AccuWeather Expert Senior Meteorologist Alex Sosnowski said that people should not use long-range forecasts as a strict guide but rather look at how the weather patterns evolve.
A typical weather pattern involves a storm crossing the U.S. every three to five days or so, and long-range forecasts can show the trends in precipitation and temperatures as a result.
"On average, a given weather pattern may last three to five days, but there are some exceptions where you can lock into longer patterns of sunshine or cloudy weather," Sosnowski said. "This spring has been a good example of a longer-lasting weather pattern."
Drier and warmer spells versus cooler and wetter periods can be spotted in the AccuWeather 30-Day Forecast. Weather trends can be observed by watching how far above or below normal temperatures are expected to be and by following the chance of precipitation and precipitation amounts.
Each day in the AccuWeather 30-Day Forecast includes the forecast high and low temperatures, the patented AccuWeather RealFeel® temperature, sky conditions and chance of precipitation, wind speed and direction, rain, snow and ice amounts, thunderstorm probability, cloud cover and UV index.
Along with the forecast, historical information, such as normal temperatures, records and temperatures recorded one year ago, is provided.
If a given forecast high is 65 degrees for Memorial Day, the normal high for the date is 60 degrees and the record high for the date is 77 degrees, a lot of information can be gathered. Conclusions like 'it might not be ideal weather for swimming, but it might be great weather for hiking' can be made from these details.
A graph at the bottom of the detailed 30-Day Forecast has a plot of the average high and average low compared to AccuWeather.com's forecast high and low for each date. Record highs and lows are plotted on the map as well. This graph can provide a quick view of useful information for planning.
