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.

The big story around here (and across much of the nation) is the scorching heat that can result in record-breaking highs around here today, tomorrow, and on Sunday. Temperatures should peak later today near 100 degrees, and they’ll surge on Saturday and Sunday well up into the 90’s. Relief is on the way for early next week with noticeably cooler conditions expected for Monday, Tuesday and Wednesday along with the chance of showers and thunderstorms.

The big story across much of the nation is the influx of high heat and humidity and the southeastern states will be impacted as well. After highs today not far from 90 degrees, temperatures will then surge well up into the 90’s over the weekend and early next week and humidity will be a very noticeable factor as well.
