WEATHER BLOG: Sunday

Looking at surface analysis the cold front has passed through our region last night and is well offshore. Today will be a cooler day behind the front but with a westerly wind our temperatures will top off around seasonable levels. Normal for this time of the year is 64 degrees. It will be windy with the westerly flow with winds sustained 10-20 mph and gust near 25-30mph. As we go into tonight the winds will lessen up as high pressure moves across the Southeast. Tomorrow we will see a little less mixing as the pressure gradient is not as strong so our high temperatures will be around the same
temperature as today even with warmer 850mb temperatures. A warm front will be draped across Virginia where the warmest air will remain tomorrow. Tuesday will be our warmest day as the high pressure shifts off the east coast and a low pressure system moves through the Great Lakes into Ontario. This is going to lift the warm front north into New England. This is going to shift our winds from the west to southwest Tuesday.

This will allow for our surface temperatures to rise to near 70 degrees with the cold front back in western NY/PA. The front will come closer to the eastern seaboard Tuesday night with a broken line of showers moving into western areas of the viewing area. The front will slow down once Wednesday as it pushes into the Atlantic ridge. This will allow for showers to persist during the day on Wednesday as the front slowly moves through the region by the evening. Thursday will be a drier day as high pressure moves in and our temperatures really cool off with highs near 60 degrees. Friday another a cold front will approach the region from the west with a more major air mass change. A northern piece of energy bringing the cold air along with it will move into the Northeast while a southern system will move into the Southeast. The northern piece will bring rain to the western parts of the viewing area by the evening which could be
tricky with the trick or treating in the western suburbs. The rain will move into the I-95 corridor by the midnight hour or so. This will allow for a dry evening from I-95 eastward. From this point on it will all depend on if the southern system will merge with the northern system. Right now it could merge off the coast of DELMARVA to Newfoundland so we will keep an eye on this. But cooler weather will be ushering in for the weekend.
