High pressure slid off the coast yesterday allowing for warmer and more humid air to push into the Mid-Atlantic region from the Tennessee Valley and it’ll stay quite warm and humid here likely right through the first half of the upcoming weekend. A weak frontal system has stalled out just to our south and it’ll result in more unsettled weather around here; especially, later in the week. While showers and thunderstorms should be relatively isolated today and Thursday, they'll become more numerous on Friday and especially on Saturday. Some of the storms that form late Saturday can be severe as a strong cold front arrives. Following the frontal passage it'll turn slightly cooler and less humid on Sunday and the beginning of the next work week looks quite comfortable in the Mid-Atlantic.

High pressure sat on top of the region yesterday providing us with comfortable weather conditions, but it’ll turn warmer and more humid later today as a weak disturbance and associated cool front approach the region. That frontal system will then stall nearby on Wednesday and then it bounces back to the north as a warm front later in the week. As a result, we’ll have somewhat unsettled weather for the reminder of the week and upcoming weekend with a daily shot at showers and thunderstorms primarily focused in the late day and evening hours. Any thunderstorm that forms in the type of weather pattern can be on the strong side with locally heavy rainfall. A stronger cool front could push through the area later in the weekend perhaps leading to less humid and slightly cooler conditions by early next week.

The week will start off comfortably warm in the Mid-Atlantic region with relatively low humidity levels, but as high pressure pushes off the east coast over the next couple of days, the heat and humidity will build into the area. After highs today in the mid 80's, it looks like we'll climb to near 90 degrees for the remainder of the week. With the uptick in moisture after today, there will also be an increasing chance of showers and thunderstorms for the middle and latter parts of the week.

The warmest stretch of weather so far this season will continue for the next couple of days with highs near 90 degrees before it turns cooler and less humid for Sunday and Monday. There can be an isolated shower or thunderstorm late today or early tonight, but an even better chance exists for late tomorrow as a strong cold front arrives. Some of the thunderstorms that form late tomorrow can reach strong-to-severe levels. After a comfortable start to the new week, the heat and humidity will build up again by the middle of next week.

High pressure will continue to control the weather around here today providing us with another day of sunshine and very warm conditions. The humidity will increase today as the temperatures climb to the 90 degree mark for afternoon highs. Temperatures will climb to 90 degrees on Friday afternoon as well and there can be some shower and thunderstorms activity late in the day and tomorrow night and the threat for showers and storms will continue on Saturday as a frontal system approaches the region. It’ll turn a bit cooler early next week following the passage of the frontal system.

High pressure will build into the area today and help produce plenty of sunshine to go along with quite warm temperatures and moderate humidity levels. Temperatures will climb to 90 degrees on Thursday and Friday and there will be an increase in humidity as well in this first extended stretch of summer-like weather for our area. There can be some shower and thunderstorm activity late Friday, Friday night and Saturday as a frontal system approaches the region. It’ll turn a bit cooler early next week following the frontal passage.

Showers and thunderstorms associated with a warm frontal passage will pull away later this morning and the afternoon promises to become quite warm and humid with partial sunshine. The second half of the week will feature the first extended stretch of summer weather so far this year in the Mid-Atlantic region with high temperatures near 90 degrees on Wednesday, Thursday, Friday and Saturday. A couple of weak disturbances this weekend could bring a return of showers and thunderstorms to the Mid-Atlantic region and it should turn slightly cooler early next week.

The first stretch of summer-like weather is coming our way this week and highs during the second half of the week will approach the 90 degrees on a daily basis. High pressure will push offshore today and lose control of our weather after providing a very nice weekend in the Mid-Atlantic region. A warm front will lift through the region late tonight and likely produce showers and thunderstorms from late tonight into Tuesday and some of the rain can be heavy at times. High pressure will build back into the area at mid-week and it’ll turn summer-like for the second half of the week.

A strong cold front is passing through the region early today with clouds and lingering showers, but it’ll pave the way for a nice break in the action from the recent very wet weather pattern here in the Mid-Atlantic. Winds will increase noticeably from a northwesterly direction and the humidity will drop sharply later today compared to recent days. High pressure building over southeastern Canada should be strong enough and close enough to produce decent weather around here through much of the upcoming weekend. More showers and thunderstorms will likely return to the Mid-Atlantic region on Monday and Tuesday and temperatures will climb well into the 80's.

An unusually strong low pressure system for the 20th of June will move towards northwestern Pennsylvania by later today and a strong surface cold front will slide towards the east coast. At the same time, a powerful wave of energy in the upper part of the atmosphere will move over the Mid-Atlantic region. As a result, there can be an outbreak of severe thunderstorms from later this afternoon into early tonight that could impact the DC-to-Philly-to-NYC corridor. Once the strong cold front clears the coast by early tomorrow, the threat for rain will wind down, humidity will drop, and the winds will pick up noticeably from a northwesterly direction gusting to 30 mph at times. High pressure will build into the area later tomorrow and it may just stay in control for most of the upcoming weekend, but more showers are possible around here by Sunday night or Monday.
