Low pressure located this evening over the Nebraska/ KS region with a frontal system extending east will move East NE before starting to move more eastwards..
This low pressure will be located over central Illinois by Friday afternoon . This low should move east from there into eastern Indiana by Friday evening and will begin to push a warm front towards the region.
This is what you call a SWFE ..or a South West Flow Event..warmer air will begin to penetrate into the upper levels..while at the surface some seasonable to slightly below seasonal air will be in place.
Due to the timing of this system in the over night period..we have included the potential for mainly higher elevations to receive a winter mix but for the most part we are expecting a cold rain across the region.
Generally at this time we think that snow accumulations would be less then an inch with surface temperatures in the coldest areas in the middle 30s overnight…
This low should slide south of PA..and off the east coast…
Rain should develop towards the midnight hour and last into early Saturday AM
