Forecast: Cooler Air, But More Sunshine Today

Yesterday, did you notice the humidity drop in the morning? A cold front moved through the area and ushered in much drier air.

The cooler air didn’t really get here until last night, which is why it was so warm in the afternoon Tuesday. Now that the Canadian air is here, it will hang around for a while and bring us seasonably cool weather for the next week or even two.

Tuesday could end up being the warmest day in the next 14, tough to predict this far out — but it's definitely possible.

The jet stream is re-configuring itself again in the never-ending cycle of undulations across the continent. We’ve been on the warm side of things for the past two weeks, and now we are transitioning onto the cooler side of the equation.

The first half of June often ends up with a cool period before the heat and humidity of summer take over in earnest.

There are some shower possibilities during this new pattern. The first comes on Friday. I’m not forecasting the showers to last all day, but there could be a period of them during the middle of the day.

Saturday is still shaping up as the driest of the two weekend days. It will also the turn out the warmest with highs inland getting to the mid to upper 70s. Cooler sea breezes continue over Cape Cod. Sunday brings back the chance of showers, but the timing may be such they occur late in the day.
