Crisp nights, warm afternoons, and sunny skies aren't going anywhere anytime soon. While it’s ideal weather to spend time outdoors, the dry conditions elevate fire risks, so exercise extra caution with any outdoor burning. Over in the tropics, there are a few areas to monitor.

Tonight & Tomorrow: Clear skies and light winds will set up another crisp night across the region. Temperatures will fall fast, ultimately bottoming out in the upper 40s north and lower 50s south. Light jackets will no longer be necessary a few hours after sunrise as highs jump through the 60s and 70s. Look for a high in the mid-80s on Thursday under sunny skies.

Up Next: A strong ridge of high pressure in the upper atmosphere will overspread the region and hold firm straight through the weekend. Acting like an invisible shield repelling clouds and precipitation, sunshine will continue to dominate. That will push highs into the middle, and possibly upper 80s throughout the rest of the workweek. Despite the daytime warmth, nights will remain chilly with lows dipping into the low 50s.

Expect afternoon highs to take a step back through the weekend as slightly cooler air marches in from the east. High clouds will also factor into the forecast early next week, potentially trimming daytime highs by a degree or two into the lower 80s. Rain will also remain difficult to find, amplifying drought concerns. The lack of rain only amplifies drought concerns. Dry vegetation often increases the risk of grass fires in fall, so do exercise caution when burning, even without an official Red Flag Warning.

The Tropics: Subtropical Storm Josephine formed off the East Coast on Wednesday afternoon. Once attached to fronts, the system has finally shed those off, allowing the storm to officially be designated as subtropical. In essence, a subtropical system is a hybrid storm of sorts, partially tropical and partially non-tropical. They draw power from both warm ocean water (tropical source) and the clash of warm/cool air in the atmosphere (extratropical source). A full explanation of subtropical storms can be found HERE. Josephine will not technically make landfall, but its proximity to the East Coast will bring high winds, coastal flooding, and dangerous surf to parts of the New England and Mid-Atlantic coasts.

Meanwhile, another region of low pressure located several hundred miles east-southeast of Bermuda is producing a disorganized area of thunderstorms. There is a low chance of development with this system as it slowly drifts north through the Atlantic.
