As the arctic air mass starts to slowly give way starting today, temperatures will slowly begin to moderate back to more seasonable levels.
High pressure over Maine will give way to the high pressure system over the Mississippi River Valley leading to scattered to variable cloud cover and warmer temperatures overall. Temperatures today through tomorrow will range from the mid to upper 30s for highs and upper 10's to mid 20's for lows. However winds from the west at 5 to 15 mph with gusts over 20 mph will support wind chills in the 20's through tomorrow.
A weak area of low pressure will move through the Philadelphia and New York City metropolitan areas tomorrow night on through Sunday with a few scattered snow showers possible. No accumulation is expected though. Temperatures will continue to moderate as the core of the high pressure system shifts off the Southeast coast. Low temperatures will fall into the mid to upper 20's throughout the region. High temperatures on Sunday will rebound into the upper 30's to mid 40's.
High pressure will remain in control with steadily warmer temperatures. Scattered to variable cloud cover can be expected through Thursday before a cold front brings widespread rainfall to the region on Friday. Low temperatures will range from the upper 20's to lower 30's on Monday and mid 30's to lower 40's thereafter. high temperatures will range from the mid to upper 30's on Monday and then lower to mid 40's over the interior and mid to upper 40's along the coast thereafter.
