After a cold frontal passage in the overnight hours, the pressure gradient between the departing low and an incoming high pressure system will tighten today and the result here will be increasingly strong winds from a west-to-northwest direction...gusting to 40 mph or so. A secondary cold front will pass through the area this evening and it will usher in a chilly air mass for the mid-week with temperatures below-normal for the middle of April. It does warm up rather quickly later in the week and the first half of the weekend is likely to feature high temperatures in the upper 70’s although showers may be a threat on Saturday with an approaching cold frontal system.

We’re not quite done yet with the cold air intrusions into the northeastern part of the nation and the next strong cold front can produce some strong-to-severe thunderstorm activity tonight in portions of the southern Mid-Atlantic region with downpours, vivid lightning and damaging wind gusts on the table. Following the passage of a strong cold front, the winds will become a big factor on Tuesday and Tuesday night with gusts of 40 mph or so from a west-to-northwest direction. The risk of severe weather will increase this weekend across the nation’s mid-section as another clash develops between incoming cold, dry air to the west and warm, humid air to the east.

After a chilly and unsettled start to the weekend, high pressure edged back into the region on Sunday and this system shifts offshore later today and a warm front will lift through the area. A strong cold front then pushes across the region from later tonight into early Tuesday and a secondary cold front crosses on Tuesday night. Winds will become a noticeable factor on Tuesday following the initial frontal passage with gusts to 40 mph or so on the table from a west-to-northwest direction. It turns much cooler at mid-week with temperatures back to well below-normal levels, but much milder weather returns for the late week and especially for the beginning of the upcoming weekend.

Wet and unsettled weather will stick around in the Mid-Atlantic region through the first half of the weekend and the colder-than-normal temperatures will remain as well. Waves of low pressure will produce occasional showers here this morning and then steadier, heavier rain from this afternoon into Saturday and total amounts can reach an inch or more which is welcome news in the still somewhat dry Mid-Atlantic region. In fact, this air mass will be chilly enough that snowflakes can mix in at times from late tonight into early Saturday and accumulations are possible across higher elevation locations of northeastern PA. High pressure will resume control later in the weekend and it should turn milder early next week; however, another strong cold front will usher in a chilly air mass on Tuesday night and Wednesday.

A strong cold front came through the region last night and it has ushered into the Mid-Atlantic region an unseasonably cold air mass for this time of year with its origins up in the Arctic region. Temperatures today will do no better than the middle 40’s for afternoon highs and there will be a strong NW wind producing much lower wind chill values. Temperatures are likely to drop to below-freezing later tonight bottoming out in the middle-to-upper 20’s across many suburban locations. With high pressure in control at mid-week, there should be plenty of sunshine on Wednesday; however, temperatures will remain below-normal throughout the Mid-Atlantic region.
