Other than a few showers on Saturday afternoon and evening, the last several days have been almost identical to each other. It's been a relative rarity this year to cobble together three or four nice days in a row but since Sunday we have been able to do just that thanks to a blocking pattern out in the Atlantic, which helps keep us in the "nice" pattern on the dry side of the upper level low in the Atlantic. Knowing that we have not always been the beneficiaries of such nice weather in May before as upper lows have been cruelly parked overhead, this stretch of nice weather has been beneficial for farmers who have been able to work their fields, beneficial for outdoor enthusiasts who have been tired of being cooped up indoors, and beneficial for pollen producing trees and flowers as allergy levels have been miserably high.
Daily high temperatures have changed little over the past five days, with only Allentown's 69 degree high on Saturday the one exception from a "stuck in the seventies" pattern that the region has seen. High temperatures have varied little of late, a rare exception to a Spring that would feature 30 and 35 degree temperature swings from one day to the next as warm fronts would bring a tease of warmth and cold fronts would slap March back in our face -- all in the course of 18-30 hours in several instances this year. These temperatures are generally where we should be at this time of the year -- Philadelphia has been one or two degrees above average each day since Saturday while Allentown has averaged exactly to "normal" each day.
In May, being average is not a bad place to be!
