Fast-moving low pressure is generating more rain in the Mid-Atlantic region, but it will be replaced by high pressure as we begin the last weekend of April. Unfortunately, that high pressure system will also be a quick-mover and a strong cold front will arrive later in the day on Saturday and late day/early evening showers are likely, maybe even an isolated thunderstorm. Much cooler-than-normal air will push into the region for late Saturday night and Sunday with highs confined to the 50’s as we close out the weekend. A major warm up will begin in earnest on Tuesday as temperatures climb well up into the 70’s and this warmer-than-normal stretch of weather should continue through the end of the work week. In fact, temperatures later next week should easily reach the 80’s for highs and some spots may see a flirtation with the 90 degree.

A much better day is on tap for today following the dreary day on Wednesday which was filled with clouds and light rain. Today’s dramatic improvement will be rather short-lived; however, as a quick-moving low pressure system will impact the region on Friday with more clouds and rain. High pressure then rapidly pushes into the area on Saturday, but this will be quickly followed by a strong cold front passage on Saturday night and the front could spawn a few showers around here during the PM hours. Following this cold frontal passage, much cooler air will return for later Saturday night and Sunday with temperatures again below-normal for this time of year. Looking ahead, a major warm up is coming to the Mid-Atlantic region for the Tuesday-to-Friday time period of next week with the 80’s very likely for highs on some of those days.

There will be another chilly shot of air dropping southeastward this weekend into the Northeast US and Sunday will turn out to be cooler-than-normal for this time of year, but there are signs that a major warm up is coming next week. In fact, it looks like the major warm up will coincide quite nicely with the calendar change to May (on Tuesday) with the 80’s quite likely for highs during this warm stretch of weather - perhaps even with a run at the 90 degree mark at some point later next week. Looking even farther ahead, next week’s warm up does not appear to be the end of the cooler-than-normal air masses coming our way as it is likely to turn much cooler again during the second week of the new month.

Low pressure will move slowly through the region today and there will be plenty of clouds and residual occasional light rain and drizzle. A better day is on tap for Thursday, but another low pressure system should bring more rain to the area by the end of the work week. High pressure will build into the area on Saturday and then a cold frontal passage on Saturday night will usher in cooler air for Sunday.

Low pressure will move slowly over the next couple of days from the Gulf region to the Mid-Atlantic coastline and this will result in a soaking rain event around here from late today into later tomorrow. Rainfall amounts from later today into Wednesday will likely end up in the 1-2 inch range in the DC-to-Philly-to-NYC corridor. Another low pressure system and its associated cold front may affect the region with more rain at the end of the week.

High pressure that provided us with a nice weekend will push off the New England coastline later today and this will open the door for a soaking rain event in the Mid-Atlantic region. Low pressure will lift slowly northward from the Gulf states to the Mid-Atlantic coastline over the next couple of days and the likely result will be 1-2 inches of rainfall in the DC-to-Philly-to-NYC corridor by the time later Wednesday rolls around. Another low pressure system and cold front may affect the region by the early part of the weekend.

A strong cold front pushed through the region on Thursday and ushered in more unseasonably cold air for the region. Temperatures today will be confined to the lower 50’s for highs which is way below-normal for this time of year and winds will continue to be quite strong out of the northwest generating lower wind chills. The weekend will be decent with dry and cool conditions prevailing as high pressure moves into the Northeast US. Looking ahead, there is the chance for a strong low pressure system to develop near the Mid-Atlantic coastline by the middle of next week and this could lead to another significant rain event for the region.

Low pressure will push east of here later today and drag a cold front through the region accompanied by occasional showers. This front will usher in another unseasonably cold air mass for this time of year and strong northwest tonight and Friday will make it feel even colder than the actual air temperature. Highs on Friday will be confined to the low-to-mid 50’s which is well below normal for mid-April. The weekend will feature dry and cool conditions as high pressure moves into the Northeast US. Looking ahead, there is the chance for a strong low pressure system to develop near the Mid-Atlantic coastline by the middle of next week and this could lead to another heavy rain event for the region.

It’ll turn milder today compared to yesterday’s chill, but more unseasonably cold air is headed our way for the latter part of the week. Low pressure will trek across the northern states over the next couple of days and generate more accumulating snow for the Upper Midwest and Northeast US. This system will drag another cold front through our region and strong NW winds will pump in colder-than-normal air for Thursday night and Friday following some shower activity on Wednesday night and Thursday.

A vigorous upper-level feature is dropping southeastward from the Great Lakes region this afternoon and headed right over the DC-to-Philly-to-NYC corridor. As a result, showers are breaking out generally in areas north of the PA/MD border and they should head towards Philly and NYC later in the day and a couple of showers could very well sneak as far south and east as the DC metro region. Much colder-than-normal air is entrenched in the region and there can be some snowflakes seen around the big cities later today into early tonight.
