Throughout Memorial Day weekend, allergy sufferers in the Boston area and much of New England face elevated tree pollen levels. While the weekend starts with mostly cloudy and cooler conditions on Thursday, which may bring some morning sprinkles, moderate tree pollen levels will persist. As the weekend progresses, Friday is expected to bring more sunshine and comfortable air, but this brighter weather will contribute to a rise in pollen counts. Saturday will remain cool and mainly dry, continuing the trend of elevated allergy concerns across southern New England. However, showers are forecasted to become more widespread on Sunday and into Memorial Day Monday, providing temporary relief by lowering pollen levels for some individuals. Unfortunately, as the region transitions into the following week, warmer weather and intervals of sunshine will return, leading to another increase in tree and grass pollen levels by Tuesday and Wednesday. Allergy sufferers should prepare for fluctuating conditions throughout this period.
