Severe thunderstorms occurred yesterday in eastern Pennsylvania, concluding with a squall line that progressed through the tri-state area early today with heavy rain and wind gusts over 40 mph. With the upper level trough departing this morning, drier conditions will return through the late week and weekend, with temperatures gradually rebounding into the mid to upper 80s into early next week before the next potential for thunderstorms.
After an unseasonably strong low pressure system produced a widespread 1 to 2 inches of rain across the region on Saturday, an upper level trough persists over the eastern half of the US but with a gradual warming trend continuing as temperatures return into the 80s for the majority of the upcoming week.
A strong shortwave trough will progress through the region today, resulting in strong to severe thunderstorms over western NJ into Pennsylvania, with additional rain possible on Wednesday before a drier ending to the week.
Heat and humidity made a brief return to the region ahead of a strong cold front on Tuesday, producing severe thunderstorms in New Jersey, Long Island and New England but largely bypassing western parts of the tri-state area. Warm temperatures will not last for long, however, as an anomalously strong ridge becomes stationed over the western US placing the region under a cooler than average pattern with frequent rain events over the next week.
A strong cold front will progress through the region today, accompanied by a strong mid-level jet streak and a warm and unstable air mass to produce scattered strong to severe thunderstorms, capable of producing strong to damaging wind gusts and an isolated tornado risk later this afternoon. This will be the last summer-like outbreak for a while, as a trend towards an anomalously strong northeast US trough may result in a much colder and wetter ending to the week more typical of spring than late June.
The remnants of Tropical Storm Bill, the second named storm of this year’s hurricane season, passed through the tri-state area last night with substantially less impact than anticipated, with rain totals generally remaining below an inch. Additional isolated storms are possible tonight, but with an otherwise warm and humid air mass lingering through Tuesday, when a cold front may produce severe thunderstorms followed by a cooling trend into the longer range.
Drier and warmer conditions will briefly return into the tri-state area today as a weak cold front shifts to the south, with temperatures likely to rise into the mid 80s this afternoon. Rain is expected to return this weekend as Bill’s remnants continue to make the long journey from Texas to New Jersey, but with uncertainty regarding how much rain spreads into the tri-state area. Additional thunderstorms are possible towards the second half of next week as any sustained heat remains well to the south.
Yesterday’s frontal boundary shifted south of NYC after producing locally heavy rain, but will retreat again north today as a warm front before another cold front comes in from the northwest, initiating scattered thunderstorms which may produce localized strong wind gusts. Drier conditions will return for the midweek period before attention shifts to Tropical Storm Bill, currently making landfall in Texas and which may have some indirect impacts in the region in the longer range.
A weakening squall line progressed through the tri-state area last night, producing relatively weak wind gusts but with rainfall totals exceeding 1/2 to locally 1 inch. A stalled front will linger over the tri-state area today with a continued risk of isolated showers and thunderstorms continuing into Tuesday, with an otherwise dry midweek period as focus shifts into the Gulf of Mexico, where a tropical disturbance may spread inland through the US.
