Surface Map 2 PM Tuesday
Well, it’s not exactly pretty, but at least our weather is for the most part dry & fairly comfortable. A low pressure system and associated frontal structure centered just of the mid-Atlantic coast this afternoon continues to supply some cloudiness to our region courtesy of the south to southwest steering flow aloft. High pressure centered over the Canadian Maritimes is still exerting enough influence to keep us dry. Next significant weather system is a cold front that will bring a band of showers or rain in by late Thursday or Thursday evening (based on current timing).
Sky becomes partly cloudy tonight. Lows mostly in the 50′s (some upper 40′s in the cold pockets to the north). A combination of clouds & some sun Wednesday. Highs in the 70′s. Partly cloudy Wednesday night. Lows 58-63. Partly to mostly cloudy Thursday. Showers or rain by late in the day or evening. Highs 76-81. Mostly sunny Friday. Highs 70-75. Early peek at the weekend: looks mostly dry. Partly cloudy. Maybe a scattered shower. Highs 68-73.
Two very different days coming up this weekend. Saturday will be warm & humid with some showers & t-storms around in the afternoon & evening. A couple of these could become strong to severe. Highs will be in the 80′s. Sunday will be mostly sunny with low humidity and highs between 75-80.
It is going to be muggy tonight, with a partly cloudy sky and low temperature holding between 65-70. There may be some areas of fog or low clouds around early Saturday morning, however it will become partly sunny until some showers and storms get going during the afternoon. The threat for some showers & t-storms will continue into part of Saturday night, followed by late clearing. Lows cool to the mid 50′s-low 60′s by sunrise Sunday.
