Looking at the surface chart, radar and infrared satellite.

High pressure continues to exit the region as a very strong cold front approaches the region. Ahead of the front a strong southwest flow is going to develop hiking temperatures to above average levels for today into tomorrow morning. Currently temperatures are mild and the region is dealing with a mix of sun and some clouds.

On the radar and satellite we can see the disturbance moving up out of the Midwest into the Great Lakes. As well as another disturbance in the southern stream over the Southeast US. Both of these features are going to slightly interact, which will help enhance impacts in our region.

Ahead of the cold front rain will be very heavy at times. We're also going to be seeing Embedded thunderstorms. A few of these thunderstorms could possibly be strong to severe. Due to the chance of winds mixing down to the surface 

Winds  of 10-30 miles an hour With gust of 40-50 even as high as 60 or 65 miles an hour. could bring down some trees and or power lines leading to scattered power outages and perhaps some damages. General rainfall amounts of 0.5 to 1.0 inches with localized higher amounts possible can be expected.  Moderate to heavy rain could lead to ponding on roadways and some localized urban flooding due to clogged drains. The cold front is going to come through the region moving west to east and should be moving across Maine Friday evening and exiting the region tomorrownight.

Behind the cold front Temperatures are going to crash. They will likely fall 30-35 ° F in a few hours.  This will likely lead to a flash freeze, causing wet surfaces to ice up and turn into black ice.

on Friday, Lake effect snow first sets up east of the  lakes Erie and Ontario and then as the system pulls away these bands will shift south and east. Those who get under the most significant parts of the band could see several inches of lake snow.

After this storm leaves the region We are going to stay in an active and volatile Pattern For the next couple of weeks, As these frontal systems come through everyday or two bringing a temperature rollercoaster with chances for rain, mix and snow. I'll be posting a small update on the long range pattern later today.
