Rain on the way...again

The earliest snow since 1979 fell yesterday at Mt. LaCoste in the Great Smoky Mountains.

Upper level low pressure over the Ohio Valley will finally begin to slide north and east towards the Jersey Shore on Wednesday and allow moisture to move north into the St. Lawrence Valley. The high pressure that has given us a break for the last couple of days will begin to break down in coverage today. We will still have another sunny day before clouds increase tonight and rain develops on Wednesday. Look for a cool breezy day Thursday with rain all day. It appears another 15-25mm of rain is likely across the region. The Thanksgiving Weekend at this point looks sunny and seasonable.

Just a couple of tidbits from around the weather world. Yesterday record high temperatures pushed north into Montana and southern Saskatchewan. Assiniboia reached 28.8C eclipsing the previous record of 25C. Meanwhile low temperatures produced widespread frost in northern and central Michigan and temperatures in the 30's F as far south as Oklahoma City. Despite the warmth in the northern plains, it snowed in the southern Sierra Mountains yesterday and at 2pm in the afternoon it was -22C and snowing in Alert, NWT. There was even a light coating of snow across the highest elevations of the Great Smoky Mountains in Tennessee.
