There is high risk of severe weather later today in the Mid-Atlantic region as several ingredients come together to enhance upward motion and destabilize the atmosphere. There were some showers around earlier today, but the late afternoon and evening hours will present the greatest risk for the severe weather. The primary hazards on the table include damaging wind gusts and heavy rainfall, but isolated tornadoes cannot be ruled out. Showers and thunderstorms can linger on Wednesday; especially, along and to the south and east of the I-95 corridor as the cold front pushes towards the eastern seaboard. Refreshing air will follow the frontal passage on Wednesday night and great weather is destined for the Mid-Atlantic region on Thursday and Friday.

Severe weather affected the Mid-Atlantic on Saturday, and another high risk is on the way for this afternoon and evening as a cold front pushes towards the region. Not everyone will get hit by the strong-to-severe storms, but ingredients are coming together for what looks like multiple rounds of showers and thunderstorms...some of the storms can be severe and some of the rain will be heavy…watch out for localized flash flooding. Showers and thunderstorms can linger into Wednesday; especially, along and to the south and east of the I-95 corridor. A refreshing air mass will arrive on Wednesday night and the weather looks great for Thursday and Friday.

Severe weather affected the Mid-Atlantic region on Saturday, and another threat is on the way for later tomorrow. Not everyone will get hit by the strong storms, but ingredients are coming together for what looks like multiple rounds of showers and thunderstorms...some of the storms can be severe and some of the rain can be heavy. Showers and thunderstorms can linger into mid-week; especially across the southern part of the Mid-Atlantic and then a refreshing air mass will arrive on Wednesday night and Thursday. Meanwhile, there is an intensifying tropical system over the northern Gulf, and it is likely to reach named tropical storm status (would be Bertha) in the near term.

High pressure builds into the region today and the new work week will start off on a nice note with plenty of sunshine and moderately warm conditions. The next cold front approaches later tomorrow and it can bring us multiple rounds of showers and thunderstorms...some of the storms can be strong-to-severe and some of the rain can be heavy. There can be lingering showers into mid-week, but a refreshing air mass is to follow into the Mid-Atlantic region for much of the second half of the week.

Following the passage of a weak cold front and combined with some more wildfire smoke in the area which can dim the skies at times, temperatures today will get knocked down a bit from recent days. The wildfire smoke had its origins in southern Canada and the low-level wind flow has pushed it into the Mid-Atlantic region. An active weather day is setting up for Saturday as a frontal system and an impressive wave in the upper atmosphere will likely produce numerous showers and thunderstorms during the first half of the weekend. Some of the storms on Saturday can be strong-to-severe and some of the rainfall can be heavy. The front should clear the area on Sunday with improving weather conditions likely going into the early part of next week.

There is the threat of severe weather and heavy rainfall on Saturday in the Mid-Atlantic region as the overall weather pattern will result in high instability across the area. The pattern will feature an intense ridge of high pressure centered over the Rocky Mountain States with northwesterly flow over the Great Lakes/Northeast US. Often, this kind of flow results in “lines” or “complexes” of thunderstorms dropping to the south and east from the Great Lakes to the northeastern states and that is on the table for the first half of the weekend. The potential exists for damaging winds, isolated tornadoes, heavy rain and localized flash flooding as precipitable water amounts in the atmosphere will climb to quite high levels. Meanwhile, wildfire smoke from Canada will continue to be an issue as we slide into the end of the week, and it will dim the skies at times through Friday.

Today will be another hot one in the Mid-Atlantic region with afternoon highs well up in the 90’s in many areas and there will be areas of smoke from still-active Canadian wildfires to our north and west. In fact, the wildfire smoke could stick around into tomorrow given the current directional flow of low-level air and it will certainly dim the skies at times. There can be a shower or thunderstorm later today, tonight, and on Friday, and the weekend will get off to an active start with a renewed chances of showers and thunderstorms on Saturday.

Temperatures will soar today to near the century mark in the DC metro region with strong high pressure ridging extending into the area from the Northern Plains. A frontal system will pass through the area later in the day and it may usher in some wildfire smoke from Canada that can stick around for a couple of days and dim the skies at times. It stays rather hot during the next couple of days and then the pattern becomes much more unsettled this weekend with the chance of strong-to-severe thunderstorms and some heavy rainfall on both days.

The overall weather pattern may be setting up for a severe weather and heavy rain threat in the Mid-Atlantic region during the first half of the upcoming weekend. The pattern will feature an intense ridge of high pressure centered over the Rocky Mountain States by the weekend with northwesterly flow over the Great Lakes/Northeast US. Often times, this kind of flow results in “lines” or “complexes” of thunderstorms dropping to the south and east from the Great Lakes to the northeastern states and that is on the table for Saturday. The potential exists for heavy rain/flash flooding as well as precipitable water in the atmosphere will climb to high levels. The weekend threat will be preceded by hot weather that can see temperatures surge to near the century mark on Wednesday anywhere along the DC-to-Philly-to-NYC corridor. One final note, wildfire smoke from Canada will likely drop south and east into the Mid-Atlantic region during the next couple of days and it certainly can dim the skies at times.

High pressure in the upper part of the atmosphere will expand to the Mid-Atlantic region today from the Northern Plains leading to hotter weather around here for the next few days. In fact, temperatures are likely to reach the lower 90’s today, and then soar to near 100 degrees on Wednesday – likely the hottest day of the week. The next few days will generally be relatively quiet in terms of precipitation chances though an isolated thunderstorm or two will be possible. More widespread unsettled weather returns at the end of the week and during the early part of the weekend with the approach of a cold frontal system. This unfolding pattern for the early part of the weekend could result in a heavy rain/flash flooding threat for the Mid-Atlantic region and possible strong-to-severe thunderstorms.
