Boston meteorologists share details about the timing of today's rain, as well as tomorrow's Halloween trick-or-treating weather forecast.

Once again, there is a very amped up and active weather pattern in the Boston area during Halloween week. First, there is a major category 5 hurricane, Melissa, set to make landfall in Jamaica before charting a course off the East Coast later this week.

This fast-moving storm will produce steady to heavy rain late Thursday into the overnight. Halloween starts out wet but dries out for evening trick-or-treating.

The rain is expected to begin in Western Massachusetts between 4 and 6 p.m., before making its way north and east to Worcester, then Boston and the coast by the evening. Easterly winds are expected to pick up as the storm arrives, with gusts eventually reaching 20 to 30 mph.

The USS Nimitz is returning to its home port in Naval Base Kitsap in Washington state after having been deployed to the Middle East for most of the summer as part of the U.S. response to attacks by Yemen’s Houthi rebels on commercial shipping. The carrier is on its final deployment before decommissioning.

A storm Thursday into Halloween could bring both tricks and treats, with Hurricane Melissa possibly having an indirect impact on our rainy and windy weather.

Boston is in for more rain in the first half of the week, with sunny, cool weather setting in headed towards next weekend, according to National Weather Service forecasts.

A storm chaser from Massachusetts got a rare and dramatic look inside Hurricane Melissa after flying directly into the Category 5 storm’s eye.

A multi-million dollar partnership between Boston and U.S. Army Corps of Engineers to study coastal storm risk is one of many projects that may be in jeopardy after the Trump administration announced a pause of $11 billion in projects.
