Forecast Highlights:

Over the last few days, hot and humid conditions were observed across the region along with scattered thunderstorms; most of these storms so far stayed north, west and south of the area so far. Starting today, more widespread storms are expected across the region as a blocking pattern develops with a frontal system stalling over the East Coast for the next 7-10 days, with most, if not all days featuring a risk of showers and thunderstorms, possibly heavy.

June 25, 2013: Heat, Humidity, Storms Continue

Forecast Overview:

Today - Thursday: As the frontal system slowly makes its way towards the region, scattered afternoon/evening storms are expected across the region again on Wednesday and Thursday, focusing mostly north and west of NYC. Wednesday will be hot again with highs in the upper 80s to low 90s away from the coast and mid to upper 80s near the coast, although Thursday will slightly cool down with increased cloud cover, with highs reaching the mid 80s to near 90 degrees along with continued humid conditions.

Thursday Night - Beyond: A stronger low pressure will develop over the interior Northeast on Thursday night, tracking north into Canada as a frontal system stalls over the East Coast due to strong ridging in the western Atlantic. This setup will result in tropical moisture spreading up the coast, with this pattern likely continuing through the first week of July resulting in most of, if not all days containing a risk of scattered thunderstorms, potentially heavy. There is a higher risk of storms on Thursday night into Friday as the low pressure makes its closest approach before tracking into Canada, with scattered storms expected to continue into the weekend and next week. It will not rain in the entire area every day, as the storms are expected to remain generally scattered. By the time this pattern ends in early July, parts of the region especially north of NYC may receive several inches of rain.

June 24, 2013: Stormy Pattern Begins Today

Forecast Highlights:

As a hot and humid air mass spread into the region, temperatures peaked in the upper 80s to mid 90s away from the coast, which along with humid conditions resulted in heat index values reaching the mid to upper 90s. Scattered storms formed across parts of the region today, only the first day in what is likely to be a long stretch of stormy conditions as a frontal system stalls over the East Coast, resulting in a risk of storms for most days into the first week of July.

June 23, 2013: Heat Continues; Stormy Pattern Develops

Forecast Highlights:

A stretch of several days of hot and humid conditions begins today, with temperatures through Wednesday in the mid 80s to low 90s, humidity resulting in higher heat index values, and a risk of isolated storms during most afternoon/evenings, especially north/west of NYC. As a trough begins to set up over the central US, temperatures will cool down for the late week into next weekend as a wetter pattern likely develops.

June 22, 2013: Hot, Humid Next Week

Forecast Highlights:

Dry and seasonable conditions continue across the region today with highs reaching the low to mid 80s away from the coast. A warmer and more humid air mass will spread in from tomorrow through the middle of next week, however, resulting in temperatures reaching the upper 80s to low 90s along with a risk of isolated thunderstorms and heat index values near the mid 90s.

June 20, 2013: Seasonable Weekend, Then Hot, Humid

Forecast Highlights:

A high pressure remains in control through the late week and weekend, with temperatures slowly warming up and generally remaining near average along with mostly sunny skies. A warmer air mass will spread in by Sunday, with heat and humidity returning for the Sunday-Wednesday time frame along with a risk of isolated thunderstorms, increasing by mid-late next week.

June 19, 2013: Sunny, Mild Ending To Week

Note: The 2013 Atlantic hurricane season is now posted in the Long Range Forecasts page.

Forecast Highlights:

A cold front moved through the region last night after having produced widespread showers and thunderstorms, some of them strong/severe, especially over northern NJ where 1-2 inches of rain fell and flash flooding was observed. A high pressure building into the region will provide mostly sunny skies and mild temperatures through Saturday, followed by a hot and humid air mass building into the region for next week along with a risk of scattered thunderstorms.
