Fischer Short Range 10/26
As we push into Thursday, cold air begins to filter in from the north and west. The cold front that has been moving across the Midwest will move into Kentucky and Pennsylvania. Cold air advection is expected over the Indiana and Illinois throughout the day.
The precipitation will start to shift farther east with the front. Also in the tropics, Rina will begin to push northward bringing with it large amounts of rain.
For Friday, the colder air really begins to take hold. A much larger portion of the midwest has 850mb temperatures below the freezing mark. A ridge will also start to take shape to the west stablizing the weather pattern.
A large portion of the country looks to be dry for Friday. However, an area of rain will begin to work into Washington state. These showers will then begin to move south and east into Montana. Down in the Caribbean, the largest amounts of precipitation associated with Rina will begin to move toward Cuba as Friday progresses.
