High pressure is pushing off the coast this morning and a slow-moving low pressure system will impact the region with some rainfall from later this morning into the late night and it’ll be noticeably colder as we close out the work week. In fact, it'll be cold enough across the higher elevations regions of east-central and northeast PA this morning for some ice and/or snow to fall at the onset of this precipitation event. This late week system looks like it will get out of here just in time to squeeze out a pretty decent-looking mainly dry and noticeably milder weekend before another system impacts the region early next week. It’ll turn even warmer on Monday and Tuesday and the combination of a warm front and a cold front will likely result in occasional showers on both days and perhaps a few thunderstorms mixed in as well.

A slow-moving low pressure system will impact the region with some rainfall from late tonight into tomorrow night and it’ll get noticeably cooler as we close out the work week. The late week system looks like it will get out of here in time to squeeze out a pretty decent weekend before another system produces more rain in the area from later Sunday night into Tuesday.

The month of April began with a colder-than-normal air mass in the eastern US and it looks like we’ll have additional cold air outbreaks over the next couple of weeks or so. Teleconnection indices such as the Arctic Oscillation (AO) and North Atlantic Oscillation (NAO) both signal a sharp drop in coming days to negative territory which typically results in the penetration of cold air outbreaks from central Canada into the eastern US. Medium-range forecast maps of 500 mb height anomalies support this notion of additional cold air outbreaks as we progress through the month of April with “high-latitude blocking” in evidence over northern Canada and Greenland.

Strong low pressure over the western Atlantic will push to the northeast today and our winds will pick up in intensity with gusts to 30 mph possible during the mid-day and afternoon hours. With the return of the sunshine, temperatures should climb to 60+ degrees this afternoon, but the wind will make it feel somewhat cooler. Another low pressure system will impact the region with showers on Thursday night and rain on Friday/Friday night. The late week storm system is likely to get out of here in time for us to squeeze out a pretty decent weekend before another system threatens us with rain by Sunday night or Monday.

Low pressure will intensify rapidly later today along the Southeast US coastline and then make a push to the northeast over the western Atlantic Ocean. Its main impact will be south and east of the immediate I-95 corridor with some rain and wind at the NJ coastline, but some shower activity cannot be ruled out here later tonight. Another low pressure system will impact the region later in the week with more rainfall as a warm front arrives on Thursday night and then a cold front on Friday.

After a spring tease on Saturday with temperatures in the 70’s, a strong cold frontal passage on Sunday ushered in a cold air mass for this time of year and it looks like another early spring night is coming to the DC-to-Philly-to-NYC corridor with low temperatures generally below-freezing. On Tuesday, low pressure will form and intensify along the Southeast US coastline and then it’ll make a push to the northeast tomorrow night and early Wednesday as a full-fledged nor’easter. The corridor between DC and NYC is likely to be spared the worst of the storm’s impact, but eastern New England could very well get hard hit with strong winds and some heavy precipitation.

Another shot of cold air has pushed into the Mid-Atlantic region from central Canada and we’ll stay colder-than-normal for the next couple days as we begin the new month of April. Low pressure will intensify off the Carolina coastline by late tomorrow, but it looks like its main impact will stay just to the east of here as it slides into the western Atlantic. This system, however, still needs to be closely monitored. High pressure will build into the region for much of Wednesday and Thursday and then another low is likely to bring us some rain on Thursday night and Friday.

The warm up that began yesterday will intensify today and highs should exceed the 70 degree mark on Saturday afternoon. Unfortunately, the warm up comes to a grinding halt on Sunday as a strong cold front slides through the Mid-Atlantic region with some shower activity and a much colder air mass will become quite noticeable by Sunday night along with a stiffening north-to-northwest wind. Colder-than-normal conditions will persist through mid-week in the DC-to-Philly-to-NYC corridor resulting in a chilly start to the month of April and we’ll have to watch a coastal storm which could impact the region in the Tuesday night/Wednesday morning time frame.

Today is Opening Day for the Phillies and the timing will be just right as a significant warming trend will be getting underway in the Mid-Atlantic region. After a frosty start to the day, low-level winds will switch to a south-to-southwest direction this afternoon resulting in a push of milder air and temperatures should climb to near 60 degrees just in time for the home opener. This warm up will intensify on Friday and Saturday and despite plenty of clouds on both days, afternoon highs should reach the 60's on Friday and 70 degrees on Saturday. Unfortunately, the warm up comes to a grinding halt on Sunday as a strong cold front slides through the Mid-Atlantic region with numerous showers and a much colder air mass will become quite noticeable by Sunday night along with a stiffening north-to-northwest wind. Colder-than-normal conditions will persist through mid-week in the DC-to-Philly-to-NYC corridor resulting in a chilly start to the month of April and we’ll have to watch a storm near the southeast US coastline to see if it can push northward along the Atlantic seaboard.

It looks like we may have to wait a bit longer for sustained springtime warmth in the Mid-Atlantic region as despite a dramatic warm up on Friday and Saturday, we’ll turn sharply colder again for the first half of next week. In fact, there can be a second cold shot late next week that makes its way into the Mid-Atlantic region which would mean we may have to wait until the second week of April for more sustained springtime warmth. In addition, there will be a deep upper-level feature sliding across the southern states early next week with cold air in place across the NE US/Mid-Atlantic. This system could push off the Carolina coastline and stay south of here, but it’ll be something to closely monitor in coming days to see if it can make a run up the eastern seaboard.
