FIRST ALERT SUMMARY

Skies are becoming more cloudy tonight with temperatures a bit warmer! Lows are getting down into the mid to upper 50s by the early morning hours.

A cold front is moving in tonight and will bring a 20% chance of a few isolated showers and sprinkles to the region for the early morning hours Wednesday. Most of the rain will be east of the Midlands by around 10am. Then we see sunny skies by the afternoon with high temps in the upper 70s.

High pressure over the Great Lake states will dominate our weather Thursday. This gives us sunny skies with lows in the low 50s and highs in the mid 70s.

Friday we have mid 50s in the morning and high temperatures in the low 70s by the afternoon. Clouds are starting to build once again as our high moves over New England and pushes some moisture from a low in the western Atlantic into South Carolina. There’s also a low pressure in the northern Gulf that will start moving our way.

The clouds are thicker Saturday and we add a 20% chance of showers. High temps are in the low 70s and lows are in the low 50s.

Sunday the moisture from the low pressure system moving in from the southwest reaches the Midlands and increases our chance of rain to 50%. This lasts overnight into Monday morning. As of now it looks like some rain showers for Halloween, especially in the morning. There’s still a chance most of the rain will be out of the area by the time trick-or-treating begins.

In the tropics there’s an unorganized cluster of showers to the east of Bermuda that has a 10% chance of development in the next 5 days. It is called Tropical Wave Invest 94-L. As it tracks to the west and north, we could see impacts for New England as some models have it moving inland north of New York City. But it looks like conditions are not conducive for development.

There’s another wave that has a 30% chance of development north of the Dominican Republic within the next 5 days.

There’s an area north of South America that has a 20% chance of development in the next 5 days as well. We will keep our eyes on all of these systems.
