[notice]Due to a busy schedule, a brief update was posted today. The next full update will be posted on Thursday, August 1.[/notice]
Since the strong ridging broke down on July 21, a cooler pattern has set up and looks to persist through the 10-day range as high latitude blocking displaces the polar vortex into southern Canada. A wave of low pressure will move through the region tomorrow, producing widespread showers and thunderstorms, capable of producing heavy rainfall with up to 1 inch expected, locally 2″ or higher. Due to the rain and cloud cover, cooler high temperatures are expected in the mid 70s to low 80s.
Partly sunny skies are expected for Friday and Saturday with drier conditions and highs in the low to mid 80s. As a cooler air mass moves into the region, highs will cool down into the upper 70s to low 80s for Sunday through the middle of next week, with overnight lows in the 50s away from NYC and the coast. A wave of low pressure looks to potentially move through the region on Tuesday and Wednesday; while the exact setup is uncertain, given the overall pattern the area would be favored to initially be in the northern end of the wave, which may produce a chilly, cloudy and rainy day on either of these days, followed by a brief warm up back into the 80s as another trough likely digs into the Midwest.
The next full update will be posted tomorrow, on Thursday. Storm updates will be posted in the afternoon and evening hours as well.
