Halloween Is Around The Corner! Will Your Forecast Be Clear And Calm Or Full Of Spine-Chilling Rains?

Halloween Proofing That Halloween Costume?

BOO! Did I scare you? No? Well, your Halloween forecast might!

Check out the breakdown of who should be spending the days leading up to Halloween waterproofing and insulating their costumes.

Trick: Northwest Set For A Scary, Soggy Halloween

I hope nobody is planning on going as a sweet treat this year, because you might just melt with all the rain expected. A new storm system will come ashore by Halloween and likely stick around into the bewitching hours. In addition to the rain, winds could also be increasingly gusty from the Pacific Northwest to the Northern Rockies. If you can wait for the weekend, there may be drier periods.

Treat: Southwest, Much Of The Rockies Likely To Have Best Costume

Just a few passing clouds and mild temperatures are likely to make these regions quite nice for trick-or-treating this year. Afternoon temps in the 60s, 70s and 80s will drop into the 50s and 60s after sundown. Parents might want to pack an extra jacket for the little boos in Colorado, Wyoming and Utah, and temps in some spots into the 40s or cooler if you’re in a high-elevation spot.

Potential Trick: Spooky Temp Drop Expected In The Northern Plains and Much Of The Midwest

While it could be worse this time of the year, you’re going to want an extra layer for your little monster. Afternoon temps will be in the 30s and 40s in the western Great Lakes, but will fall into the 30s across much of the Midwest by midnight. Some will be haunted by temps near freezing in the Dakotas by late evening. From the Central Plains east to parts of Illinois, temps will be less frightening – 40s and 50s throughout the evening. Clouds are likely to pass through the entire area and overcast skies are possible closer to the Great Lakes.

Trick Then Treat: Northeast Will Be Watching The Timing Of A Low-Pressure System

Timing is key for the Northeast! A low-pressure system will be moving up the East Coast late in the week, and the exact speed (and size) of that storm will determine if the Northeast has rain and maybe some screaming winds outside to contend with. But on the black-cat-tail end of that system, northwesterly winds and cold air could mean toil and trouble for the Great Lakes with some lake-effect precipitation. And a few models are showing a ghostly cold spot that could support some lake-effect snow. A bit of flexible scheduling might be a treat for Halloween celebrations, because moving things to Saturday will help make sure things are clear so you can take to the skies on your broomstick.

Trick: Southern Plains Could See Light Rain

Here's a project for any little witches and wizards in the Southern Plains! A bit of light rain could be heading for your trick-or-treating territory, but timing could work out in your favor to keep the rain after midnight in the darkest hours of Saturday morning... This could be a good opportunity to practice some weather-related spellwork to keep the forecast from changing too much and to keep the rain at bay!

Treat: Much Of The Southeast To See Mild Temperatures

Mostly tranquil weather is likely with temperatures falling through the 40s and 50s in the Tennessee Valley and Carolinas and the 50s and 60s along the Gulf Coast. The only low-probability ghoul in the forecast is that if Melissa comes out of the Caribbean slower than forecast, it could kick up waves along any beach parties. Melissa will not bring any rain, wind or witches to the Southeast. A few passing phantom clouds are possible high in the sky across the Southeast.
