SYNOPSIS
High pressure building from the northwest today will pass across Sunday morning and then head offshore by Sunday evening. The high will remain in control through late week. A few weak disturbances may approach from the north next weekend.

NEAR TERM /UNTIL 6 AM SUNDAY MORNING/
As an upper level trough shifts east this morning, heights rise aloft as an upper ridge builds over the eastern US. At the surface, high pressure builds in from the northwest. The air mass building in will be drier and a bit cooler than the past several days. Highs today will likely top out in the upper 70s to lower 80s. With dewpoints in the upper 40s to lower 50s, the air will have a comfortable feel.

Given the dry air mass and mostly clear skies, with no more than some thin high clouds, radiational cooling tonight should help the usual cool spots get down to the upper 40s/lower 50s.

SHORT TERM /6 AM SUNDAY MORNING THROUGH MONDAY NIGHT/
Heights continue to rise aloft through Monday night. High pressure at the surface will move overhead early Sunday and then offshore by Sunday evening, but will remain in control through the week.

The short term period will be dry and mostly sunny. Some energy rounding the upper level ridge will pass overhead Sunday afternoon/evening, but will likely just result in some high clouds.

Temperatures Sunday will be just a few degrees cooler than Saturday, with the same low dewpoints. As the high shifts offshore later on Sunday a return flow sets up and moisture increases. Dewpoints return to the mid 60s on Monday, with highs in the 80s for most.
This will likely be the last day before a heat wave sets up for the rest of the week.

LONG TERM /TUESDAY THROUGH SATURDAY/
**Key Point**

* A long duration heat wave is expected during most of next week beginning on Tuesday and lasting until Friday or Saturday. Heat index values of greater than 95 degrees are expected for much of the area during this time.

A strengthening deep layer ridge will be positioned over the East Coast by Tuesday with a surface high pressure system over the Western Atlantic. Low level flow on the west side of the high pressure will allow for a southerly or southwesterly flow through much of the extended period. This will allow for the advection of both low level moisture and warm air.

The upper level ridge continues strengthening in intensity through the middle and end of the week, eventually peaking in strength by Thursday with 500mb heights between 594 and 600dam. This highly anomalous strength in the upper level ridge will allow for a prolonged heat event to take place over the entire Northeast. By Tuesday, surface highs will be in the 90s for much of the interior portions of the area with coastal locations in the middle to upper 80s.

Heat persists through the week, eventually allowing temperatures to rise into the middle to upper 90s for interior portions of the Lower Hudson Valley, NE NJ, and southern CT. It would not be that surprising if some locations hit 100 degrees, especially into Thursday and Friday. Because this is a fairly early season heat wave, relatively cooler waters only in the 60s will shelter Long Island and immediate coastal Connecticut from experiencing the worst of the heat, but may result in some enhanced surface moisture over these areas. Heat index values will likely be greater than 95 degrees during each afternoon from Tuesday through at least Friday for everywhere except Long Island. This may eventually facilitate heat headlines.

Given the duration and intensity of the anticipated heat, it is important to take precautions to protect one's health, particularly those without effective cooling and/or adequate hydration. Some heat- sensitive industries and infrastructure will likely be impacted by the extent of this heat as well.

AVIATION /18Z SATURDAY THROUGH THURSDAY/
High pressure builds over the area from the north into Sunday.

VFR.
