Yesterday featured high temperatures near the 100 degree mark in many locations along the DC-to-Philly-to-NYC corridor with 98 degrees recorded at DCA, 96 degrees at IAD , and 97 degrees at BWI. The bad news with respect to this current hot spell is that the peak of the heat may actually come today with numerous 100 degree readings on the table in the I-95 corridor. The good news is that much relief is in sight and next week looks much closer-to-normal in terms of overall temperatures.
The very strong ridge of high pressure to our north will weaken later in the week and also shift southward. As a result, the heat will not be quite as intense by the time we get to Thursday afternoon and much relief is likely by the end of the work week on Friday. In addition, the chance of PM showers and thunderstorms will return to the area on Wednesday as the ridge begins to break down and this threat of rain will increase on Thursday…any thunderstorm that forms can be strong-to-severe on both of these days.

Yesterday featured high temperatures near the 100 degree mark in many locations along the DC-to-Philly-to-NYC corridor with a record-breaking 99 degrees recorded at Philly International Airport (PHL). The bad news with respect to this current hot spell is that the peak may actually come later today with numerous 100 degree readings on the table in the I-95 corridor compared to Monday. The good news is that much relief is in sight by the end of the work week on Friday and next week looks much closer-to-normal in terms of overall temperatures.
The last time Philadelphia officially reached 100 degrees at the International Airport (PHL) was on July 18th, 2012…and it could happen again later today. The very strong ridge of high pressure to our north will weaken later in the week and also shift southward. As a result, the heat will not be as intense here on Wednesday and there will be a chance of PM showers and thunderstorms. Temperatures drop even further on Thursday as a back door cool front approaches the region and the chance of showers and thunderstorms will increase. Any thunderstorm that forms on both Wednesday and Thursday can be strong-to-severe. This back door cool front could actually bring much relief by Friday as an ocean flow of air could develop and end the work week on a cool note.

The next couple of days will remain moderately warm and there will be scattered showers and thunderstorms; primarily focused on the afternoon and evening hours. The pattern turns warmer and drier for the Thursday to Sunday time period and afternoon highs are likely to be back in the 90’s by Friday and Saturday.

The official Atlantic Basin tropical season was barely underway in June of 1972 when a polar front interacted with an upper-level trough of low pressure over the Yucatan Peninsula. Within a few days, a tropical depression formed and the system moved slowly eastward and emerged in the western Caribbean Sea by the middle of the month. The depression began to intensify over the warm waters of the Caribbean Sea and soon became Tropical Storm Agnes – the first named storm of the 1972 tropical season. Ultimately, Agnes would reach hurricane status, grow to a diameter of about 1000 miles, and become the costliest hurricane at the time to hit the US and the Commonwealth of Pennsylvania was the prime focus of its wrath.

High heat and humidity will be the rule for the next few days in the Mid-Atlantic region with very strong high pressure ridging in control. Temperatures will climb right through the 90’s on Monday and Tuesday and likely reach the 100-degree mark in many locations. The strong ridge tends to weaken later in the weak - beginning on its northern perimeter - and this should lead to scattered afternoon and evening showers and thunderstorms around here beginning at mid-week and that threat of PM rain likely lasts through the weekend. There will be a reduction in temperatures later in the week as the ridge breaks down such that we’ll likely be back to near the 90-degree mark for highs by week’s end.

After a weekend with intense heat, the first half of the work week will be noticeably cooler and there can be scattered showers and thunderstorms on each day. Temperatures today should pretty close to the 80-degree mark following the upper 90’s experienced in most locations this past weekend.

The big story across much of the eastern US is the high heat and humidity and northern Alabama will experience these conditions through the week. Temperatures right through the week should climb well up into the 90’s for afternoon highs and the humidity levels will remain high and at quite uncomfortable levels.

High heat and humidity will be the rule for the next few days in the Mid-Atlantic region with very strong high pressure ridging in control. Temperatures will climb right through the 90’s on Monday and Tuesday and flirt with the 100-degree mark in some locations. The last time Philadelphia officially reached 100 degrees at the International Airport (PHL) was on July 18th, 2012. The strong ridge tends to weaken later in the weak - beginning on its northern perimeter - and this should lead to afternoon and evening showers and thunderstorms around here beginning at mid-week and that threat of PM rain likely lasts right through the weekend. There will be a reduction in temperatures later in the week as the ridge breaks down such that we’ll likely be back in the lower 80’s for highs by week’s end.

Powerful thunderstorms barreled through the DC-to-Philly-to-NYC corridor late yesterday causing widespread damaging wind reports and power outages (e.g., 250,000 customers without power in SE PA). The passage of the surface cold front has lead the way to noticeably lower humidity today in the Mid-Atlantic region and there will be plenty of sunshine to go along with warm conditions.
The moderate humidity of today will give way to an extended stretch of high heat and humidity from later this weekend into at least the middle of next week. A very strong ridge of high pressure that has been stuck out west in recent days will move into the eastern states by later this weekend. This repositioning of the strong upper-level ridge will lead to high temperatures well up in the 90’s for multiple days all along the DC-to-Philly-to-NYC corridor...perhaps some spots can reach the 100-degree mark during this stretch. One final note, there is a good chance for a complex of thunderstorms to drop southeastward across New York State and New England later this weekend and it could produce showers and thunderstorms in the NYC metro region on Sunday.
