Forecast: Another Heat Wave Coming To Much Of The Area

The weather today will see more clouds and humidity, and temperatures won't be as warm as they have been the past few days. This is the beginning of a change in the pattern which results in a better chance of showers and the highest chance of widespread shower activity all summer.

Think of today as a transition between the dry and comfortable air of the past few days and some extreme heat and humidity coming Thursday through Saturday.

As a frontal system works through the area today we have the risk of showers. These showers won't be as widespread, but if you do get one, expect heavy downpours as a possibility.

The highest risk of rainfall is north of the Mass Pike today, and the lowest risk is over Cape Cod.

The shower threat ends tonight. Then it’s a three-day heat wave for many of us.

Temperatures Thursday through Saturday should exceed 90 over all inland areas and some spots along the coast like Boston. It will feel like it's in the upper-90s to perhaps as hot as 105 when the sun is out and temperatures reach their maximum.

The humidity will be about as high as it gets in New England through the first part of the weekend with dew points in the 70s. This means when we do have showers later Friday and especially Saturday they could contain very heavy rain, thunder and even a small chance of severe weather. This active pattern will last into Monday.

This may finally be the period when some much needed rain does occur and helps with the drought. Remember, we need several months of average rainfall to get out of the drought, but this may be a good start.

Wednesday: Becoming more humid with some clouds and a few showers. Highs 75-83.

Thursday: Hot and humid with hazy sunshine. Highs 88-94. Cooler on the Cape and Islands.

Friday: Partly sunny, humid and hot. Some showers possible. Highs 85-93.

Saturday: Partly sunny, humid and hot. A few showers possible. Highs 85-93.
