DAYS 1-5 ( JULY 10-14)
Tropical Storm Fay formed just off the East Coast of the US yesterday and will make a rapid run up the coast, center making landfall over the northern Mid Atlantic tonight then racing northward up the Hudson Valley region early Saturday morning. This is going to be a very quick “event” for us here in the form of a gusty breeze, a couple waves of showers / downpours and potential thunder (which carry a slight potential of a few damaging wind gusts), and tropical humidity, and then it’s gone, just like that, leaving us with a sun/cloud mix Saturday but still quite humid. Also a lingering trough behind Fay may help ignite some afternoon showers and thunderstorms Saturday, but right now the greatest chance for this to happen is just west of the WHW forecast area, some making their way in weakening or scattered form into the region during the evening or night. Humidity comes down a notch Sunday but another weak trough swinging through may still help fire off a shower or thunderstorm in a few places during the afternoon / early evening so can’t forecast totally dry. If there is one “significant” change to this outlook it is that a slightly stronger disturbance seems slated to want to make a passing visit on Monday, and that will again increase the risk of showers and thunderstorms before drier air finally arrives for Tuesday.

DAYS 6-10 (JULY 15-19)
Limited risk for any shower / thunderstorms in weak to moderate westerly air flow much of the time. Temperatures near to above normal.
DAYS 11-15 (JULY 20-24)
A slightly stronger west to northwest flow aloft means a warm pattern with limited shower / storm chances but probably no extreme heat either.
