Low pressure has moved nearby in the overnight hours and there will be occasional rain today that can still freeze on some untreated surfaces during the early morning hours in suburban locations. A strong cold front will push through the region early tonight and winds will become gusty behind it and it'll stay moderately cold overnight and on Wednesday. However, an even colder air mass will charge into the region late tomorrow after the passage of an Arctic cold frontal system. That system can bring some snow shower activity to the area later tomorrow - perhaps even a snow squall - and then it'll turn windy and sharply colder tomorrow night and Thursday with the coldest wind chills (and temperatures) of the season so far. Some moderation in temperatures will return by the end of the week.

There will be two different parts to the current winter weather event with phase one already well underway and phase two coming from later today through Tuesday morning. Phase one featured some accumulating snow south of the PA/MD border earlier today and has had very limited precipitation so far north of the Mason-Dixon Line. Phase two will involve heavier precipitation amounts from later today into tomorrow morning as low pressure heads towards the region from the Lower Mississippi Valley. This second phase will generally feature ‘plain’ rain across the immediate DC metro region, but icing will be a big concern across much of PA, northern NJ and NYC where temperatures will hover around the freezing mark throughout the night as precipitation intensities pick up.

Low pressure will intensify over the Lower Mississippi Valley on Monday with a cold air mass in place across the Mid-Atlantic and NE US. This system has generated a west-to-east swath of precipitation that will likely only skirt the NYC metro on its north side during much of the day before more substantial precipitation arrives tonight. With the cold air in place, any precipitation today will be in the form of snow followed by a mix of snow, sleet and freezing rain tonight with small accumulations of up to a couple of inches. There can be some impact on road conditions tonight; especially, in the northern and western suburbs of the NYC metro area. Temperatures will have a hard time rising above the freezing mark and any changeover to later rain tonight will likely still result in some icing as temperatures hover near the freezing mark. Occasional 'plain' rain is likely on Tuesday before the passage of a cold frontal system that will shut off the precipitation. It'll stay cold behind the storm on Wednesday and an even colder air mass may arrive on Thursday.

One storm system continues to impact the Mid-Atlantic/NE US today with brisk NW winds and another one will impact the same area from Monday into Tuesday. The next storm will intensify over the Lower Mississippi Valley early Monday and it will take a track across the central Appalachians and to the southern New England coast by Tuesday afternoon. As the storm intensifies on Monday, it will generate a west-to-east swath of precipitation that will push into the Mid-Atlantic region during the morning or mid-day hours on Monday. The air is likely to be cold enough for a period of snow and/or ice at the onset and there are likely to be some small accumulations before any changeover to rain; especially, from the northern and western suburbs of DC to areas near and north of the PA/MD border. The precipitation will intensify on Monday night and with temperatures hovering near freezing north of the PA/MD border, a significant buildup of ice is on the table.

There will be two storms to deal with in the Mid-Atlantic/NE US over the next few days with the first storm already impacting parts of the Mid-Atlantic region and another storm will impact the same area from Monday into Tuesday. The initial storm is going to be predominately a ‘plain’ rain event in the I-95 corridor and some of it will become heavy at times, but there are a few pockets of freezing rain at this hour in areas well to the north and west of Route I-95. Patchy fog may form as well in the overnight hours as the in flux of milder air moves over still cold grounds. The departure of this initial storm will result in an influx of another cold air mass at the end of the weekend and this could set the stage for some snow and/or ice on Monday at the onset of the next storm; especially, in areas north of the PA/MD border.

Low pressure will intensify over the southeast US today and then ride up along the Atlantic seaboard tonight and Saturday. There can be occasional light rain later today out ahead of the main system, but the heavier rainfall will take place tonight and Saturday. It'll turn milder in the overnight hours with temperatures likely rising through the 40's and reaching the middle 50's on Saturday afternoon. Patchy fog may form as well in the overnight hours as the in flux of milder air moves over still cold grounds. High pressure will return for the second half of the weekend, but it’ll be quite breezy and cold on Sunday. Another storm is likely to impact the region from Monday into Tuesday and this one could have enough cold air around at the onset for a period of snow and/or ice before a likely changeover to 'plain' rain.

There will be two storms to deal with in the Mid-Atlantic/NE US in coming days with the first storm impacting this area from Friday into Saturday and the second storm Monday into Tuesday. The initial storm will be predominately a plain rain event; however, there can be some icing at the onset early tomorrow; especially, south of the PA/MD border include the N/W suburbs of DC. By late tomorrow, enough milder air will arrive for plain rain to fall in the DC-to-Philly-NYC corridor and this can become a soaking rain event from Friday night into Saturday. The departure of the first storm will result in an influx of another cold air mass at the end of the weekend and this could set the stage for some snow and/or ice later Monday as the next storm system closes in on the area.

There will be a couple of storms to deal with over the next several days with the first one predominately a rain event, but the second one can bring some snow and/or ice to the region early next week. High pressure will stay in control of our weather today providing us with some sunshine, but it’ll be quite cold for this time of year. Temperatures will only manage to climb into the mid 30’s this afternoon and the normal high for this date is 44 degrees (at Central Park). Low pressure will form quickly in the southeast US on Friday and it’ll bring us a soaking rain event from later tomorrow through much of Saturday. There can be some freezing rain and/or ice pellets mixed in at times during the day on Friday as the next storm gets underway. High pressure will return for the second half of the weekend, but it’ll be quite breezy and cold on Sunday. Another storm is likely to impact the region from later Monday into Tuesday and this one could have enough cold air around to produce some snow and/or ice in the region.

Snow in the region should wind down by late morning and there will be some clearing this afternoon as high pressure moves closer from the Ohio Valley. That high will push overhead tonight and temperatures will drop into the lower 20’s for lows by early Thursday. Strong low pressure will move up along the east coast as we head towards the weekend and this is likely to produce heavy rainfall around from late Friday into early Saturday.
