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.
