Europe had an extended period of colder-than-normal weather in April accompanied by lots of snow and now much of the US will experience an extended period of colder-than-normal weather as we transition from early-to-mid May. This cold snap could very well result in low temperature readings in the 30’s next week on multiple mornings in many suburban locations along the I-95 corridor – and that may not be the end of it as signs point to another cold shot later in the month.

Strong low pressure will move slowly northward today on the western side of the Appalachians and it will produce a significant rainfall in the I-95 corridor. Rain will fall heavily at times today and there can be a strong thunderstorm or two mixed in. Due to a blocking pattern in the upper part of the atmosphere, this system will linger in the Northeast US and continue to create instability in the atmosphere as we head into the weekend with more showers likely tonight, tomorrow and tomorrow night. In addition to the continuing shower threat in the Mid-Atlantic region, this strong low pressure system will usher in colder-than-normal air this weekend and it looks like it will stay below-normal around here well into next week.

All systems are go for a significant rain event in the DC-to-Philly-to-NYC corridor from late tonight into late Friday and it could even have a negative impact on the morning commute as heavy rain will be in much of the area at that particular time along with possible strong thunderstorms. Low pressure is now forming over the Tennessee Valley and it will strengthen over the next 24 hours as it pushes northward along the western side of the Appalachian Mountains.

Strong low pressure will push towards the eastern Great Lakes over the next 24 hours and this system will generate a significant rainfall for the DC-to-Philly-to-NYC corridor on the order of 1.00 to 2.00 inches. As the storm pulls northward, it’ll force somewhat milder air into the I-95 corridor on Friday and this could help generate some strong thunderstorm activity to go along with the periods of rain – some of which will be heavy at times. Following the passage of a strong cold front, colder-than-normal air will push into the region this weekend and, thanks to the formation of a classic “omega”-shaped blocking pattern in the upper atmosphere, it will stay colder-than-normal around here - and somewhat unsettled - for several days.

Two big weather stories going forward for the DC, Philly and New York City metro regions: (1) a heavy rain event is coming from later tomorrow night into Friday and it can be accompanied by strong thunderstorms and (2) an extended period of colder-than-normal weather from this weekend into the latter part of next week. This chilly stretch of weather could even result in accumulating snow in some of the higher elevations of the Mid-Atlantic region as well as in portions of the Ohio Valley and Great Lakes. Strong low pressure will form tomorrow in the south-central states - aided by tremendous upper-level energy - and then push northward towards the eastern Great Lakes. Colder-than-normal air pushes in this weekend following the passage of a strong cold front and thanks to the formation of a classic “omega”-shaped blocking pattern in the upper atmosphere, it will stay colder-than-normal for several days.

There are two big weather stories going forward for the I-95 corridor region from DC-to-Philly-to-NYC: (1) a significant rain event for later tomorrow night and Friday and (2) an extended period of colder-than-normal weather from Saturday through Thursday and this overall stretch could even result in accumulating snow in some of the higher elevations of the Mid-Atlantic region. Strong low pressure will form later today in the south-central US and then head towards the Great Lakes region on Thursday. Rain should overspread the I-95 corridor from west-to-east Thursday night and continue into Friday resulting in a soaking rainfall for DC, Philly and NYC of an inch and a half to two inches. Colder-than-normal air pushes in this weekend following the passage of a strong cold front and, thanks to the formation of a classic “omega”-shaped blocking pattern in the upper atmosphere, it will stay colder-than-normal around here and somewhat unsettled for several days.

There are two big weather stories for the I-95 corridor region from DC-to-Philly-to-NYC going forward over the next week-to-ten days: (1) a heavy rain event is coming that will be centered on late Thursday night and Friday and (2) an extended period of colder-than-normal weather from this coming Saturday through Thursday of next week and this overall stretch could even result in accumulating snow in some of the higher elevations of the Mid-Atlantic region. Strong low pressure will form at mid-week in the south-central US and head towards the Great Lakes region later Thursday. Rain should overspread the I-95 corridor from west-to-east late Thursday or Thursday night and continue into Friday resulting in a soaking rainfall for DC, Philly and NYC. Colder-than-normal air pushes in this weekend following the passage of a cold front and thanks to the formation of a classic “omega”-shaped blocking pattern in the upper atmosphere, it will stay colder-than-normal around here for several days.

A strong cold front passed through the region early this morning and the weather will improve today although it’ll become quite breezy and a bit cooler than yesterday It’ll turn even cooler on Wednesday and then another strong cold front will be headed towards the Northeast US later in the week. As this next cool shot closes in on the Northeast US, strong surface low pressure will form in the southern states supported by a vigorous upper-level system. The strong low pressure system area will push towards the Great Lakes later in the week and the result should be a soaking rain event in the DC-to-Philly-to-NYC corridor focused on late Thursday night and early Friday. Once the cool air arrives following that late week frontal passage, it will be slow to depart as an “omega-shaped” blocking pattern will unfold in the upper atmosphere across the nation. In fact, colder-than-normal conditions are likely in the Mid-Atlantic region from this weekend into late next week.

A strong cold front is crossing the Ohio Valley today on its way to the eastern seaboard and thunderstorms have increased in intensity and coverage at mid-day across eastern Ohio and western West Virginia. The surface cold front currently stretches from the Great Lakes through eastern Ohio and into eastern Kentucky and will pass through the Mid-Atlantic region late tonight. While there is a threat for strong-to-severe thunderstorms tonight in the I-95 corridor, an even greater chance is likely just west of here in places like western and central Pennsylvania and West Virginia where a tornado watch has already been issued by NOAA's Storm Prediction Center.

A strong cold front will approach the region later today from the Ohio Valley and it’ll turn windy and warmer with highs in the mid-to-upper 70's. Showers and thunderstorms are likely early tonight (7-11pm) and some of the storms can reach strong-to-severe levels with damaging wind gusts and downpours. Cooler temperatures will return to the region for tomorrow and Wednesday following the cold frontal passage and there will be another big cool shot arriving in the Northeast US by the end of the week. Strong low pressure is likely to form later this week with that next cold frontal boundary zone and the result here is likely to be a significant rain event
