Temperatures will be rising, but the National Weather Service is predicting that at the peak of the heat wave tomorrow, the thermometer will not reach 90 degrees.

Thirsty farms and gardens might get some relief on Saturday.

High pressure will be building into the North Country today and will remain the dominant weather feature through Friday. This should supply the region with lots of sunshine and summer-like temperatures.

A weak cold front will bring a chance of showers and thunderstorms on Saturday, but dry conditions return for Sunday right through next week as high pressure returns.

Highs today are expected in the low 80s, tomorrow about 88 degrees, and, on Saturday, about 86 degrees with a 40 percent chance of rain or thunderstorms.

Into next week, highs are not expected to top 80 degrees.
