Finally More In The Way of Sunshine For Memorial Day
Showery Rains Arrive Wednesday
Today is Memorial Day and do take a little time out today to remember those who served and gave their lives for this great nation of ours. Weather today is going to be good overall. It has been a slow march this weekend of low pressure in New England which is now far offshore. As a result we should see more sunshine today, fewer clouds and higher temperatures. We will reach highs in the low to mid 70s in most places though the coast will be cooler with local sea breezes. There may still be a few scattered showers well inland and north in Upstate NY and New England but we expect those showers to stay there and not make it down to the coast.

Tonight skies will become partly to mostly clear with most lows in the upper 40s to middle 50s. Tuesday should be a day with plenty of sunshine but there will be some high clouds coming in later in the day as we get set for another round of showery rains for the second half of the week. High temperatures Tuesday will be in the low to middle 70s except cooler along south and east facing shorelines.
The stubborn upper trough that has been over the Northeast and Atlantic Canada is finally moving out to the east. This is now going to allow low pressure developing in the Southern Plains to head to the northeast. Over the last few days and through the holiday weekend, a frontal boundary has been stalled across the Deep South to the Plains. This has created rounds of thunderstorms with severe weather in the mix. There also has been considerable amounts of rain and flash flooding.
High pressure is going to move offshore and we will set up an onshore flow Wednesday. A warm front sets up to the south and an expanding area of showery rains north of the warm front will head northeast through the Ohio Valley, Mid Atlantic states and into the Northeast US during the day Wednesday. Showery rains develop from southwest to northeast across Eastern Pennsylvania to New York State and New England.
East winds will mean temperatures Wednesday across the area will be mostly in the low to mid 60s for highs. It will actually be warmer to the northeast where clouds may take longer to increase and winds are more southerly rather than easterly. Shower rains will last into early Thursday. Then we could see a break followed by a chance for showers and thunderstorms later Thursday into Thursday night. Highs Thursday should be back into the 70s.
The cold front with this next system passes but another upper trough drops into Southeastern Canada and the Northeast for Friday and Saturday. This means another period of cold unstable air aloft and that brings clouds and the chance for showers both days. It is not an all day rain set up but one where days start with sunshine only to give way to clouds and then some scattered showers in some places. Genuine improvement likely waits for Sunday.
