Wednesday the low pressure will organize over the Central Plains will a warm front will move north in the Ohio Valley. This warm front will be the approximate location of the track of the low pressure system.
The low pressure will intensify early Thursday as it moves through the Ohio Valley. Moisture will be spread north of the cold front and ahead of the low pressure producing snow and a wintry mixture. The heaviest snow will fall just to north of the area that receives the icy mixture. As the system passes, additional moisture may be added from Lake Erie.
Current snowfall predictions from Wednesday through Friday morning are for more than ten (10) inches for counties along the lake shore. Total amounts will depend on how quickly the low jumps to the East Coast
The low pressure will intensify further off the East Coast on Friday allowing a return to much colder air advecting into the region on northerly winds. High temperatures on Friday will not rise above 20 degrees.
The extreme cold will be short lived as high temperatures on Saturday will rise to near 30 degrees. Another front will move through on Sunday which will usher a return to colder than normal temperatures for early next week. How cold this air mass will be is not agreed upon by the models at this time, but subzero temperatures will be possible overnight. Locals wanting a break from the persistent cold pattern may get their wish as there are indications that late next week the weather pattern will alter with the trough migrating to the Western USA.
