A sprawling area of high pressure, or fair weather, dominates across the Northeast Friday into Saturday with sunshine and dry air.
The combination of sun, slightly warmer than normal temperatures and no rain makes for some beautiful days, but also drives up both the pollen count and the brush fire danger.
Temperatures will jump to near 70 Saturday as the warm-up continues, but Sunday will be summery, with highs near the mid-80s. Warmth is moving northeast out of the Central Plains, and is expected to arrive to New England for Easter Sunday, producing some Saturday evening and night showers on its leading edge, then boosting temperatures for many by Easter Sunday afternoon.
U.S. & World
Though most of New England will squeeze through Easter without rain, recurring showers are likely in the North Country, and we all may find some scattered showers or thunder by Sunday evening, driven by an approaching cold front and fueled by somewhat humid air.
Though the air left behind for Patriots Day will be cooler, it’ll still be much warmer than normal at 65-70 degrees for afternoon highs, which will great for spectators but very warm for runners of the Boston Marathon, making both hydration and heat management key factors.
Cooler weather takes hold for the rest of next week as an onshore wind develops, bringing increased clouds and a higher chance of showers.
The record for April 16 is 87, but the all-time record for any Easter Sunday is 94 in 1976. We should fall short of those values, but it will feel every bit as warm Tuesday. There is a slight risk for an afternoon storm, but that will be late in the day and should be mainly across western New England.
