As we move through Sunday afternoon across the Hudson Valley… the rain showers have become more widely scattered, and fewer in number. but the unsettled, humid conditions that have been with us for days now… will remain with us until at least mid week.
THE CAUSE…
The cause of all our atmospheric instability is a persistent trough in the SE US, and a massive ridge of high pressure over eastern Canada. The result is a stalled out frontal boundary draped over the east coast. That’s sending warm and humid air up the coast, and providing some convection to the atmosphere. So each day when the atmosphere heats up… the showers and T-Storms become more numerous and widespread. That will be the case later today and tonight, as well as Monday. Unfortunately, predicting the position of these showers & T-Storms in advance is virtually impossible. So anyone with plans will need to keep an eye on the radar, to see if a rain delay is headed your way. Over the course of the next 3 days, much of the region will see 1 to 3 inches of rain, depending on exactly where those heavier downpours set up.
RELIEF ON THE WAY….
A trough will dive in from Canada on Wednesday, and spread more widespread showers and T-Storms. However, this frontal bounday will push through the region… clearing us out by Thursday. Thursday looks cooler, much less humid, and a good deal of sunshine. Best of all… overnight lows near 50° will allow those windows to open and get some fresh air in the house.
TRACKING LEE….
Hurricane Lee will continue to lurk in the Atlantic for the next several days. There are some rumblings about Lee hitting our area. We will do a more comprehensive discussion on Lee… but right now, 90% of the data keeps Hurricane Lee out to sea. About 10% of the data suggests Lee could impact New England. We will have to watch closely, but right now almost all computer data keeps Hurricane Lee’s impacts east of the Hudson Valley. More updates to follow….
