- Over the weekend, another storm system could develop in the East.
- First, parts of Kansas and Oklahoma are covered in snowfall.
- This storm could bring more snow to the Northeast, the Ohio Valley and the Appalachian Islands.
Another east coast storm could ensue over the weekend, potentially bringing more snow to parts of the Northeast, Ohio Valley and Appalachian Islands that were hit by a snowstorm earlier this week.
Similar to the storm that hit the East this week, which The Weather Channel called the Danish of the winter storm, this potential weekend eastern storm depends on the energy of two jet streams coming together.
This is because a large area of low pressure running through the middle of the plain is expected to eventually stretch eastwards.
If this lower trough of the plain can remain fairly intact heading east and coalesce with the disturbances of the northern branch of the jet, a strong low-pressure area can re-emerge in the East over the weekend.
For now, this scenario is suggested by most computer forecasting models.
But this is not guaranteed to happen. There are also typical uncertainties about the timing, the trajectory of the eastern low-pressure system, and how much cold air will be available.
For now, we’re determining our best outlook, but we’ll check for updates frequently in the coming days as the forecast becomes clearer.
First the Plains Snow
The upper low point of that plain first generates wet snow cover in some parts of the plain Wednesday and Wednesday evenings.
The largest amount of snow – more than 6 inches of patches – is expected in northwestern Oklahoma and southern Kansas.
Some easier accumulation is possible in both the Wichita, Kansas, and Oklahoma City subway areas. This can lead to ugly roads – especially bridges and overpasses – Wednesday night and early Thursday.
The outlook for Friday
Rain and some thunderstorms possible in southeast Friday.
Some precipitation should also spread to parts of the Northeast and Ohio Valley. Where there is quite cold air along the northern rim, precipitation may fall as snow, as shown on the forecast map.
By Saturday, most computer models suggest low pressure has developed somewhere along the East Coast.
As mentioned earlier, the exact trajectory of the low point will be crucial in determining where the rain-snow line will form.
For now, the chances are most likely to run from the eastern parts of the Ohio Valley and Great Lakes to the Appalachian Islands and the northeast inland.
Rainfall closer to the Northeast City Corridor 95 Northeast may rain mostly on Saturday and Saturday nights.

By Sunday, most computer models suggest that low pressure is spinning somewhere near or above New England.
Assuming this happens, the highest chance of snow accumulation on Sunday and Sunday night is over the inner northeast, primarily north and west of the 95 state.
Again, it is too early to make accurate northeast forecasts for snow and rain. Check for fresh days in the coming days.
