Clouds will thicken up this morning and another round of snow and/or ice is headed our way for later today and early tonight. Precipitation should break out this afternoon – most likely in the form of snow – but it should transition to a wintry mix by early tonight. Temperatures should slowly rise tonight and that should allow for the changeover of the wintry mix to plain rain by late tonight. A coating to an inch of snow and ice accumulations likely before the changeover to plain rain. Wednesday promises to be a milder day with occasional rain and some fog; however, the more important story will be the approach of yet another Arctic cold frontal system. That front will pass through the region late Wednesday and this will begin a downward trend in temperatures that could set the stage for significant snow on Thursday.
Once the Arctic front reaches the east coast, it will stall out due to the alignment of the upper-level winds which will prevent any significant movement to the southeast. At the same time, copious amounts of moisture will begin heading northeast along the stalled out frontal boundary zone and colder air will be pushing in from the northwest. The result could very well be a significant snow event on Thursday with preliminary estimates in the 4-8 inch range for the I-95 corridor. Very cold weather closes out the work week.
