No big changes in the pattern as we start the weekend here in central New York. High pressure just off the East Coast and low pressure now in the mid Mississippi Valley are conspiring to keep plenty of tropical moisture over central New York. With this moisture still over us Saturday and temperatures once again approaching 90 degrees, we see no reason why there wouldn’t be a few scattered showers and thunderstorms around in the afternoon. It certainly sounds like a broken record: there will be more heavy downpours in any storm that forms.
Thereafter, we will finally start to see some subtle changes in the pattern later this weekend into early next week. The stubborn and stalled trough, or low pressure in the middle and upper atmosphere is forecast by most computer models to move east and over the Northeast in the Sunday-Monday time frame. This will result in slightly “cooler” temperatures as well as a somewhat greater threat for more widespread showers and thunderstorms.
Once the trough of low pressure moves through later Monday we will lose our tropical feed of moisture but it will still feel a bit humid at least through the middle of next week. In addition, our temperatures will take a run at 90 degrees again Tuesday and especially Wednesday.
It still pretty far out in time, but there are signs that the humidity may ease a bit at the end of the upcoming weekend.
